Congratulations on the purchase of the Great Planes Eagle 580 Matt Chapman .46-.81/EP ARF! This latest Matt Chapman version has been designed to give even the most selective pilots the 3D performance they are looking for as well as the smooth, forgiving ﬂ ight that the sport modeler desires. With so many assembly steps already complete right out of the box, you will be able to spend more time at the ﬂ ying ﬁ eld and far less time at your workbench! In addition, bolt-on wings and bolt-on stabilizer halves eliminate the time consuming gluing and measuring procedures typically required on a model of this size, as well as make future repairs quick and easy. For the brushless motor users, the canopy hatch is securely held in place with our hook and magnet system for access to ﬂ ight batteries and can be quickly removed by simply sliding it forward and lifting it off.

For the latest technical updates or manual corrections to the Eagle 580 Matt Chapman .46-.81/EP ARF, visit the Great Planes web site at www.greatplanes.com. Open the “Airplanes” link, then select the Eagle 580 Matt Chapman .46-.81/EP ARF. If there is new technical information or changes to this model a “tech notice” box will appear in the upper left corner of the page.

PROTECT YOUR MODEL, YOURSELF

& OTHERS....FOLLOW THESE

IMPORTANT SAFETY PRECAUTIONS

1. Your Eagle 580 Matt Chapman .46-.81/EP ARF should not be considered a toy, but rather a sophisticated, working model that functions very much like a full-size airplane. Because of its performance capabilities, the Eagle 580 Matt Chapman .46-.81/EP ARF, if not assembled and operated correctly, could possibly cause injury to yourself or spectators and damage to property.

2. You must assemble the model according to the instructions. Do not alter or modify the model, as doing so may result in an unsafe or unﬂ yable model. In a few cases the instructions may differ slightly from the photos. In those instances the written instructions should be considered as correct.

3. You must take time to build straight, true and strong.

We, as the kit manufacturer, provide you with a top quality, thoroughly tested kit and instructions, but ultimately the quality and ﬂ yability of your ﬁ nished model depends on how you build it; therefore, we cannot in any way guarantee the performance of your completed model, and no representations are expressed or implied as to the performance or safety of your completed model.

Remember: Take your time and follow the instructions to end up with a well-built model that is straight and true.

DECISIONS YOU MUST MAKE

This is a partial list of items required to ﬁ nish the Eagle 580 Matt Chapman .46-.81/EP ARF that may require planning or decision making before starting to build. Order numbers are provided in parentheses.

4. You must use an R/C radio system that is in ﬁ rst-class condition, and a correctly sized engine and components (fuel tank, wheels, etc.) throughout the building process.

5. You must correctly install all R/C and other components so that the model operates correctly on the ground and in the air.

6. You must check the operation of the model before every ﬂ ight to insure that all equipment is operating and that the model has remained structurally sound. Be sure to check clevises or other connectors often and replace them if they show any signs of wear or fatigue.

7. If you are not an experienced pilot or have not ﬂ own this type of model before, we recommend that you get the assistance of an experienced pilot in your R/C club for your ﬁ rst ﬂ ights. If you’re not a member of a club, your local hobby shop has information about clubs in your area whose membership includes experienced pilots.

8. While this kit has been ﬂ ight tested to exceed normal use, if the plane will be used for extremely high stress ﬂ ying, such as racing, or if an engine larger than one in the recommended range is used, the modeler is responsible for taking steps to reinforce the high stress points and/or substituting hardware more suitable for the increased stress.

9. WARNING: The cowl and wheel pants included in this kit are made of ﬁ berglass, the ﬁ bers of which may cause eye, skin and respiratory tract irritation. Never blow into a part to remove ﬁ berglass dust, as the dust will blow back into your eyes. Always wear safety goggles, a particle mask and rubber gloves when grinding, drilling and sanding ﬁ berglass parts. Vacuum the parts and the work area thoroughly after working with ﬁ berglass parts.

Radio Equipment

The Eagle 580 Matt Chapman .46-.81/EP ARF requires a minimum 4-channel radio system with four 44 oz.-in. [3.2 kg-cm] minimum standard servos. If you are installing a glow engine, an additional standard servo is required for the throttle. For maximum performance, we recommend installing Futaba® S9252 servos for the elevators and rudder.

In addition, two 6" [152mm] servo extensions are required for the aileron servos. If you are using a radio system that does not support mixing functions, a Y-harness will also be required to connect the aileron servos to the receiver.

If you plan to install a brushless motor, you will need a 6" [152mm] servo extension for the ESC. If you plan to install a glow engine, you may also need a 12" [305mm] servo extension for the receiver pack depending on where on the model you install the pack. A 16" [406mm] servo extension is needed for an aft mounted rudder servo.

To achieve 3D control throws for the ailerons and elevators, 1" [25mm] servo arms are needed.

A charge jack receptacle is optional, but is useful for recharging and checking voltage of the receiver pack without removing the canopy hatch. Recommended part numbers for the radio components are provided below:

BUILDING STAND

• The stabilizer and wing incidences and engine thrust angles have been factory-built into this model. However, some technically-minded modelers may wish to check these measurements anyway. To view this information visit the web site at www.greatplanes.com and click on “Technical Data.” Due to manufacturing tolerances which will have little or no effect on the way your model will ﬂ y, please expect slight deviations between your model and the published values.

ORDERING REPLACEMENT PARTS

Replacement parts for the Great Planes Eagle 580 Matt Chapman .46-.81/EP ARF are available using the order numbers in the Replacement Parts List that follows. The fastest, most economical service can be provided by your hobby dealer or mail-order company.

To locate a hobby dealer, visit the Great Planes web site at www.greatplanes.com. Choose “Where to Buy” at the bottom of the menu on the left side of the page. Follow the instructions provided on the page to locate a U.S., Canadian or International dealer.

A building stand or cradle comes in handy during the build. We use the Robart Super Stand II (ROBP1402) for all our projects in R&D, and it can be seen in pictures throughout this manual.

IMPORTANT BUILDING NOTES

• When you see the term test ﬁ t in the instructions, it means that you should ﬁ rst position the part on the assembly without using any glue, then slightly modify or custom ﬁ t the part as necessary for the best ﬁ t.

• Whenever the term glue is written you should rely upon your experience to decide what type of glue to use. When a speciﬁ c type of adhesive works best for that step, the instructions will make a recommendation.

• Whenever just epoxy is speciﬁ ed you may use either 30-minute (or 45-minute) epoxy or 6-minute epoxy. When 30-minute epoxy is speciﬁ ed it is highly recommended that you use only 30-minute (or 45-minute) epoxy, because you will need the working time and/or the additional strength.

• Photos and sketches are placed before the step they refer to. Frequently you can study photos in following steps to get another view of the same parts.

BUILDING INSTRUCTIONS

Preparations

❏ 1. If you have not done so already, remove the major parts

of the kit from the box and inspect for damage. If any parts are damaged or missing, contact Product Support at the address or telephone number listed in the “Kit Inspection” section on page 7.

❏ 2. Attach a 6" [152mm] servo extension to each aileron

servo and secure the connector using 1-1/2" [38mm] pieces from the included heat shrink tubing. Center the servos with your radio system and install the servo arms to the servos perpendicular to the servo cases as shown. Be sure to reinstall the servo arm screws into the servos.

❏ 2. Use a covering iron with a covering sock on medium/high

heat to tighten the covering if necessary. Apply pressure over sheeted areas to thoroughly bond the covering to the wood.

Assemble the Wings

Before completing this section, conﬁ rm that the servos that you will be using will properly ﬁ t between the servo mounting block locations on the aileron servo hatch covers. Make adjustments with a hobby knife to the blocks as necessary for your brand of servos. The block positions are designed to ﬁ t a standard size Futaba brand servo.

❏ 3. Position each servo against the undersides of the aileron

servo hatch covers between the mounting blocks. Shim the aileron servos away from the hatch covers approximately 3/64" [1.2mm] to isolate them from vibration (a business card folded in thirds works well for this). Drill 1/16" [1.6mm] holes through the mounting tabs on the servo case into the blocks. Thread a servo mounting screw (included with the servos) into each hole and back it out. Apply a drop of thin CA to each hole to harden the wood. When the CA has dried, install the servos onto the hatch covers using the hardware supplied with the servos. If the servos you are using don’t ﬁ t between the blocks, remove material for the wood blocks.

❏ 1. Cut three arms from a four-armed servo arm for each

aileron servo. Enlarge the outer hole of the remaining arm with a 5/64" [2mm] drill bit. 3D aileron throws will require 1" [25mm] or longer servo arms.

Page 8

❏ 4. Use the strings taped inside the aileron servo hatches

to pull the servo leads through the wing panels.

❏ 6. Thread a nylon clevis 20 complete turns onto each 6"

[152mm] pushrod. Slide a silicone clevis retainer onto each clevis and connect the clevises to the outer holes of two control horns.

❏ 7. Position the control horns over the plywood plates in the

ailerons (if you cannot see them, hold the aileron at a shallow angle in good lighting or use a small pin to puncture the covering) using the position of the servo arms as a guide. Align the holes in the control horns directly over the aileron hinge line and mark the location of the control horn mounting holes.

❏ 5. Before ﬁ tting the hatches in place, thread a #2 x 3/8"

[9.5mm] self-tapping screw into each hatch mounting hole and back it out. Apply a drop of thin CA to each hole to harden the wood. Install the hatch covers to the wings using eight #2 x 3/8" [9.5mm] self-tapping screws and eight #2 ﬂ at washers.

❏ 8. Drill 1/16" [1.6mm] holes at the marks you made

through the plywood plates. Do not drill all the way through the ailerons! Thread a #2 x 3/8" [9.5mm] self-tapping screw through each hole and back it out. Apply a couple drops of thin CA glue to each hole to harden the wood. When the glue has dried, install the control horns onto the ailerons using four #2 x 3/8" [9.5mm] self-tapping screws.

Page 9

Servo Horn

Install the Tail Section

The horizontal stabilizer is a two-piece bolt-on design that can be taken off at any time by simply removing two screws. If, after this section, you decide it is easier to complete the model on your work table with the stab removed, feel free to do so as it will no longer be needed until it is time to set the control throws on the ﬁ nished model.

❏ 1. Test ﬁ t a CA hinge into each of the hinge slots in the

rudder and fuselage. If necessary, enlarge the slots with a hobby knife. When satisﬁ ed with the ﬁ t, insert a CA hinge halfway into each hinge slot in the fuselage. Push a pin through the middle of each hinge to keep them centered. Test ﬁ t the tail wheel assembly into the slot at the bottom of the fuselage.

2-56 (.074")

Pushrod Wire

FasLink

1/16"

❏ 9. Use tape or a small clamp to hold the ailerons in the

neutral position. Make a mark on the pushrods where they cross the outer holes in the servo arms. Make a 90° bend at the mark on the pushrod and cut off the excess pushrod 1/4" [6mm] beyond the bend. Attach the pushrods to the servo arms using nylon FasLinks. Thread the clevises up or down on the pushrods as necessary to center the ailerons with the servo arms centered. When satisﬁ ed, slide the silicone clevis retainers to the ends of the clevises to secure them.

❏ 2. Roughen the portion of the tail wheel wire that ﬁ ts into

the rudder with 220-grit sandpaper and clean it off with alcohol. Lightly coat that end of the tail wheel wire with epoxy and ﬁ t it into the hole in the LE of the rudder. Be sure not to get epoxy onto the nylon tab where it rotates on the wire. Lightly coat both sides of the nylon tab with epoxy and ﬁ t the rudder to the fuselage onto the CA hinges. Wipe away any excess epoxy with denatured alcohol. Remove the pins and adjust the rudder so there is a small gap between the LE of the rudder and the fuselage. The gap should be small, just enough to see light through the gap or to slip a piece of paper through. When satisﬁ ed, apply six drops of thin CA to both sides of each hinge without using accelerator. After the CA glue has hardened, conﬁ rm that the rudder is secure by pulling on it and deﬂ ecting it left and right.

Page 10

Install the Tail Servos and Pushrods

A servo bay is provided in the tail of the plane for an aft mounted rudder servo. An aft mounted rudder servo will reduce or eliminate any tail weight needed to balance the airplane with a heavier engine installed. An additional 16" [406mm] servo extension is needed for an aft mounted rudder servo. See the “Expert Tip” in this section detailing the aft rudder servo installation.

❏ 3. Slide the carbon ﬁ ber horizontal stabilizer tubes

into the fuselage with the shorter tube in the forward position. Fit the stab halves onto the tubes and slide them against the fuselage. Secure the stabs in place using two 4-40 x 1/2" [13mm] SHCS, two #4 ﬂ at washers and threadlocking compound.

❏ 1. Trim the covering from the elevator and rudder pushrod

exit slots in the fuselage. Temporarily insert a 2-56 x 36" [914mm] pushrod into each elevator pushrod exit slot. Use the position of the pushrod to align the elevator control horns onto the undersides of the elevator halves. Mark the locations of the control horn mounting holes onto the elevator halves and drill 1/16" [1.6mm] holes at the marks. Do not drill all the way through the elevator halves! Thread a #2 x 3/8" [9.5mm] self-tapping screw into each hole and back it out. Apply a couple drops of thin CA glue to each hole and let it harden. Attach the elevator control horns to the elevators using four #2 x 3/8" [9.5mm] self-tapping screws.

❏ 2. Attach a control horn onto the left side of the rudder in

the same fashion.

Page 11

❏ 3. Cut three arms from two four-armed servo arms (a long

servo arm will be needed on the elevator servo to achieve 3D control throw). Center the elevator and rudder servos with your radio system and install them onto the servos in the orientation shown with the servo arm screws. Enlarge the outer holes of each servo arm with a 5/64" [2mm] drill bit. Install the elevator and rudder servos into the servo tray as shown using the hardware supplied with the servos. Before drilling the mounting holes, test ﬁ t your throttle servo (if applicable) to conﬁ rm there is enough space for it next to the elevator servo. Be sure to harden the screw holes with thin CA as was done with the aileron servos.

❏ 5. With the rudder in the neutral position and the rudder

servo arm perpendicular to the servo case, mark where the pushrod crosses the outer hole of the servo arm. As you did with the aileron pushrods, make a 90° bend at the mark and cut off the excess pushrod 1/4" [6mm] beyond the bend. Secure the pushrod to the servo arm with a nylon FasLink. Make any adjustments necessary to the nylon clevis so that the rudder is properly centered and slide the silicone clevis retainer to the end of the clevis. Cut off the tip of the rudder control horn so it does not interfere with the elevator.

❏ 4. Thread a nylon clevis and silicone clevis retainer onto a 2-56

x 36" [914mm] pushrod 20 complete turns. Slide the pushrod through the rudder pushrod exit slot in the fuselage and connect it to the second inner hole in the rudder control horn.

Aft Rudder Servo Installation

❏ A. Sand and clean a 36" [914mm] pushrod with

denatured alcohol. Lightly coat 4" [102mm] of the pushrod beyond the threaded end with epoxy. Slide the included piece of carbon ﬁ ber tube over the pushrod, positioning it 1/4" [6mm] beyond the threaded end. Wipe away any excess epoxy with denatured alcohol.

Page 12

❏ B. Trim the covering from the aft rudder servo bay on the

left side of the fuselage in the location shown. Attach a 16" [406mm] servo extension to the rudder servo and secure the connection with a piece of heat shrink tubing. Install the servo using the hardware included with it. As you did with the ailerons, ﬁ nish the pushrod installation using a nylon clevis, silicone clevis retainer, and a FasLink.

Position the right elevator in the neutral position and cut off the excess pushrod 1" [25mm] behind the elevator servo arm. Join the two elevator pushrods together using two 5/32" [4mm] wheel collars, two 6-32 x 1/4" [6mm] SHCS and threadlocking compound. View the model from behind and conﬁ rm that the elevator halves are parallel. If not, make any adjustments as necessary to the clevises or wheel collars until they are.

Assemble & Install the Landing Gear

❏ 6. Attach two 2-56 x 36" [914mm] pushrods with nylon

clevises and silicone clevis retainers to the second outer holes in the elevator control horns (for 3D elevator throws, use the second inner holes in the control horns).

❏ 1. Secure the axles to the landing gear legs using the

5/16"-24 nylon lock nuts.

❏ 7. With the left elevator in the neutral position and the

elevator servo arm perpendicular to the servo case, mark the location where the left elevator pushrod crosses the outer hole of the elevator servo arm. Make a 90° bend at the mark and cut off the excess pushrod 1/4" [6mm] beyond the bend.

❏ 2. Slide a 5/32" [4mm] wheel collar onto each axle followed

by a 2-3/4" [70mm] wheel and then another 5/32" [4mm] wheel collar. Mark the location of the threaded holes in the wheel collars onto the axles. Use a ﬁ le or rotary tool such as a Dremel to grind ﬂ at spots at the marks on the axles.

Page 13

❏ 3. Reinstall the wheel collars and wheels onto the axles.

Thread a 6-32 x 1/4" SHCS into each wheel collar and tighten the screws against the ﬂ at spots on the axles. Be sure that the wheel rotates freely on the axle. Oil the axles if necessary.

❏ 4. Attach the wheel pants to the landing gear legs using

four 2-56 x 3/8" [9.5mm] machine screws, four #2 ﬂ at washers, four #2 lock washers, and threadlocking compound.

Glow Engine Installation

The Matt Chapman Eagle 580 .46 ARF is designed to be ﬂ own with a .46 to .61 two-stroke glow engine, .52 to .81 fourstroke glow engine, or a brushless out-runner motor. If you plan to install a brushless motor, skip this section as it only contains information relevant to installing a glow engine.

A 4-stroke engine is shown in this section. The installation of a 2-stroke engine will require the same procedure. A Pitts style is recommended to minimize the amount cutting required of the cowl. The stock mufﬂ er can be used. However, a section of the cowl will need to be cut away to accommodate the mufﬂ er body.

❏ 5. Attach the landing gear legs to the fuselage using four

6-32 x 5/8" [16mm] SHCS, four #6 ﬂ at washers, four #6 lock washers, and threadlocking compound.

❏ 6. Secure the tail wheel to the tail wheel assembly with a 3/32"

[2.4mm] wheel collar and a 4-40 set screw. Be sure that the tail wheel rotates freely on the axle. Oil the axle if necessary.

❏ 1. The fuel tank can be assembled as a two line system

consisting of a vent (pressure) line to the mufﬂ er and a carb line. Filling and emptying of the tank would need to be done through the carb line, or an optional fuel ﬁ ll valve (not included). The tank can also be assembled as a three line system having a vent line, carb line, and ﬁ ll line. If installing a ﬁ ll line, puncture the top of the stopper above the sealed off fuel tube hole. The ﬁ ll and carb lines should extend out 1/2" [13mm] beyond the stopper and the vent line should be bent upwards and left uncut. With the tubes installed in the stopper, ﬁ t the stopper plates loosely in place with the 3 x 25mm Phillips screw to hold the assembly together.

FILL AND CARB LINES

❏ 2. Fit the stopper assembly into the tank with the vent

line pointing toward the top of the tank, but not touching. The fuel tubing and clunks (fuel pickup) on the carb and ﬁ ll lines should almost reach the back of the tank but not touch. The clunks must be able to move freely inside the tank when assembled. Adjust the length of the fuel tubing accordingly. When satisﬁ ed, tighten the 3 x 25mm screw in the stopper to secure it in place (do not overtighten). Mark the side of the tank that must face up when installed in the plane, and we also suggest marking the tubes in the stopper.

tray. Make a strap from the included hook and loop material by overlapping the mating ends by approximately 1" [25mm]. The total length of the strap will be determined by the size of your receiver battery. Fit the strap through the slots in the motor mounting box as shown.

❏ 4. Cut a piece of foam rubber to wrap around the pack and

securely strap it to the underside of the motor mounting box. Feed the battery lead up through one of the lightening holes in the mounting box and into the fuselage. We recommend sealing the receiver pack (and foam rubber) in a plastic bag to protect it from exhaust residue. Securely strap the receiver pack to the motor mounting box.

❏ 3. For balancing purposes, a location is provided on the

underside of the motor mounting box for the receiver battery when installing a lighter weight engine. The receiver battery can also be installed behind the fuel tank or on the servo

❏ 5. Attach a 6" to 7" [152mm to 178mm] piece of fuel tubing

onto each line coming from the tank. Insert the tank into the fuselage with the correct side facing up. Fit the neck of the fuel tank through the hole in the ﬁ rewall (if the tank neck does not align with the hole in the ﬁ rewall, rotate the stopper assembly in the tank 180 degrees and ﬂ ip the tank over).

Page 15

❏ 6. Glue the plywood fuel tank brace to the fuselage as

shown. The brace should be positioned against the back of the tank.

❏ 7. If you are installing the O.S. 81FS-a engine, you will

need to trim away the nose gear bearing on the top side of the engine mount as shown. A rotary tool works well for this.

❏ 8. Using four 6-32 x 3/4" [19mm] SHCS, four #6 ﬂ at

washers, four #6 lock washers, and threadlocking compound, attach the engine mount side-mounted to the ﬁ rewall so that the engine head will be on the right side. Leave the screws slightly loose. Test ﬁ t your engine between the mount halves. Slide the mount halves against the sides of the engine and ﬁ nish tightening the mount screws.

❏ 9. Position the front of the engine drive washer 4-7/8"

[124mm] from the front of the engine mounting box. Mark the location of the engine mount holes onto the mount rails using a Dead Center Hole Locator. Remove the engine from the mount and use a 6-32 tap and drill set to create threads in the four mounting holes. Attach the engine to the mount using four 6-32 x 3/4" [19mm] SHCS, four #6 ﬂ at washers, and four #6 lock washers.

❏ 10. Install the throttle servo onto the throttle servo tray

using the hardware supplied with the servo. Be sure that the throttle servo is not touching the elevator servo.

useful). Roughen the outside of the included outer pushrod tube using 220-grit sandpaper. Slide the outer pushrod tube through the hole you drilled in the ﬁ rewall and through one of the lightening holes in the second former. Fit the plywood outer pushrod tube support over the aft end of the pushrod tube, but do not glue it in place yet. Position the outer pushrod tube so that it protrudes beyond the ﬁ rewall approximately 2-1/4" [57mm]. Glue the outer pushrod tube to the hole in the ﬁ rewall.

❏ 12. Install a brass screw-lock connector onto the second

inner hole of the throttle servo arm using a nylon retainer. Thread a 4-40 x 1/8" [3mm] SHCS loosely into the screwlock pushrod connector. Center the throttle servo using your radio system and attach the arm to the servo with the servo arm screw.

❏ 13. To make the throttle pushrod easier to work with inside

the fuselage, cut the remaining 36" [914mm] pushrod down to approximately 21" long [ 533mm] (do not cut off the threaded end). If you are installing an engine with a rear mounted carb, also cut off a portion of the threaded end, leaving 1/2" [13mm]. Thread a nylon clevis onto the pushrod 20 complete turns and install a silicone clevis retainer onto the clevis.

❏ 11. Drill a 3/16" [4.8mm] hole in the ﬁ rewall inline with the

throttle arm on the carburetor (an extra long drill bit is very

Page 17

should be plugged with the included aluminum fuel line plug and will conveniently ﬁ t into the ﬁ ll line clip. Be sure to replace the fuel line plug after ﬁ lling or draining the fuel tank. The pressure line will be installed onto the mufﬂ er after the cowl installation section.

❏ 16. Seal up the electric cooling hole cutout with thick CA

or epoxy.

❏ 14. Insert the pushrod through the outer pushrod tube

and through the screw-lock pushrod connector on the throttle servo arm. Connect the clevis to the throttle arm on the carburetor. Make any necessary bends in the pushrod so the pushrod can actuate the throttle without contacting the motor mounting box. When satisﬁ ed, adjust the pushrod position in the screw-lock pushrod connector so that the throttle servo properly opens and closes the carburetor. Use the radio system to test the operation of the throttle. Tighten the SHCS in the screw-lock pushrod connector and cut off the excess pushrod 1/4" [6mm] behind it. Glue the outer pushrod tube support to the second former and glue the outer pushrod tube to the outer pushrod tube support.

Brushless Motor Installation

The Eagle 580 Matt Chapman .46-.81/EP ARF is designed to be ﬂ own with a .46 to .61 two-stroke glow engine, .52 to .81 four-stroke glow engine, or a brushless out-runner motor. If you have installed a glow engine, skip this section as it only contains information relevant to installing a brushless motor.

Be sure to read and understand the instructions that come with the ESC and motor before attempting to operate the system. Also read the lithium battery handling and usage warning on page 26 of this manual.

❏ 15. CA glue the plywood ﬁ ll line clip to the bottom center

of the ﬁ rewall. The clip can be fuelproofed with epoxy. Cut the fuel tubing coming from the tank to the proper length and connect the carb line to the engine. The ﬁ ll line (if installed)

❏ 1. In order to achieve the required distance from the

ﬁ rewall to the face of the bolt-on prop adapter, the ends of the motor mount halves must be cut shorter. A hacksaw or rotary tool with a cutoff wheel work well for this. The aft motor mount half must be shortened by 7/8" [22mm] and the forward motor mount half must be shortened by 1/2" [13mm]. Reassemble the motor mount using threadlocking compound on the mount screws.

Page 18

❏ 2. Attach the out-runner motor to the brushless motor

mount using the included 3 x 8mm machine screws and threadlocking compound. If you haven’t done so yet, install the prop adapter to the motor case with the hardware included with the motor and threadlocking compound.

adapter is 4-7/8" [124mm] from the ﬁ rewall. When adjusting the aluminum motor mount, take care not to inadvertently increase or decrease the amount of right thrust from what is already built into the motor mounting box.

❏ 5. Knock out the cooling hole in the bottom of the ﬁ rewall.

❏ 3. Attach the motor mount to the ﬁ rewall using four

6-32 x 1/2" [13mm] SHCS, four #6 ﬂ at washers, four #6 lock washers, and threadlocking compound.

❏ 4. Loosen the screws that join the aluminum motor mount

halves and slide them together so that the front of the prop

❏ 6. The mounting holes in the included ESC tray match

the mounting pattern of the recommended Great Planes brushless ESC. Other brand speed controllers can be secured to the tray with the included hook and loop material.

❏ 7. Make a strap from the included hook and loop material

by overlapping the mating ends by approximately 1" [25mm]. If you are installing the recommended Great Planes ESC, make the strap 6" [152mm] long. If you are using a different brand ESC, you can use the strap to secure the ESC to the tray. The total length of the strap will be determined by the size of the ESC.

Page 19

❏ 8. Secure the ESC tray to the underside of motor mounting

box using the hook and loop strap. Use three #4 x 3/8" [9.5mm] self-tapping screws to attach the recommended Great Planes ESC to the ESC tray.

❏ 10. Connect the motor lead wires to the ESC. Wrapping

the wires around the brushless motor mount will keep the excess length neatly out of the way.

❏ 9. Use CA glue to attach the ABS air scoops to the sides

of the motor mounting box as shown.

❏ 11. Attach the hook side from a package of self-adhesive

hook and loop material (not included) to the center of the battery tray. Cut it to length as needed. As you did for the ESC, make another hook and loop strap from the included material to secure the LiPo batteries to the tray. Fit the strap through the slots in the tray as shown. Apply the loop side from the self-adhesive hook and loop material to the packs (use additional pieces to secure multiple packs together) and test ﬁ t it onto the tray. When you balance the airplane after the assembly has been completed, the exact position of the packs on the tray will be determined and you should

Page 20

mark this position on the tray for reference. Now would also be a good time to conﬁ rm that the motor will rotate the correct direction by temporarily powering up the motor using the ESC and your radio system (do not install a propeller yet!). If the motor rotates the wrong direction (it should rotate counterclockwise when viewing it from the front), disconnect any two of the three motor leads and swap their position.

Install the Receiver

❏ 1. Make a strap from the included hook and loop material to

ﬁ t your receiver. Connect the servos to the receiver, being sure that the leads will not interfere with the tail surface pushrods. Depending on the ESC being used (if applicable), you may need a servo extension to reach the receiver. Cut a piece of foam rubber (not included) to ﬁ t your receiver and strap the receiver in front of the tail servos as shown. A receiver antenna tube is provided for FM and PCM receivers. Trim the covering from the antenna tube exit slot if necessary.

To prevent the battery hook and loop strap ends from ever falling down out of the slots in the tray, cut small pieces of left over self-adhesive hook and loop material and attach them in the locations shown. When you unstrap the batteries from the tray, use the small pieces to hold the strap ends up and out of the way while you remove the batteries.

Although the strap could also be glued in place along the underside of the tray, doing so will prevent you from drawing the strap tightly around the packs. Allowing the strap to ﬁ t freely in the slots in the battery tray is the preferred method.

❏ 2. If you installed a brushless motor, make another strap to

secure your receiver battery next to the receiver. For balancing purposes, the receiver battery can also be installed in the front of the plane above the ESC location.

❏ 3. Openings are provided on both sides of the fuselage

for mounting an on/off switch. The hole spacing is made for a Futaba mini switch harness. If you are using a different switch, you may need to modify the opening, or mount it in a different location. An optional charge jack receptacle can be mounted below the switch.

❏ 11. Cut the covering from the cool air exit on the underside

of the fuselage in the location shown.

❏ 4. Neatly bundle and secure the excess lengths of

servo leads out of the way. If you have a radio with mixing capabilities, the aileron servos can be connected directly to two different channels on the receiver when you install the wing panels. If not, a Y-harness will need to be connected to the aileron channel on the receiver.

Page 21

Finish the Model

❏ 1. Before ﬁ tting the cowl,

make any cutouts necessary for your power system. If you are installing a glow engine, a cutout must be made for the engine head, exhaust, needle valve access, and cool air exit. A rotary tool such as a Dremel works very well for cutting holes in ﬁ berglass. We suggest proceeding slowly with this step to achieve a clean, accurate hole around the engine head. Gradually enlarge the hole as needed checking your progress frequently. A paper template of the engine head can be made. However, the cowl cheeks will make a template more difﬁ cult to use.

❏ 3. Fit the cowl onto the fuselage. Use the spinner backplate

(you may need to enlarge the hole in the backplate to match the size of your motor shaft) to center the position of the front of the cowl 1/8" [3.2mm] behind the backplate. Be sure that the colors on the cowl and fuselage are aligned. Temporarily tape the cowl in place or have a helper hold the cowl. Measure 4" [102mm] along the lines from the aft marks on the tape and mark the cowl where to drill the four cowl mounting holes.

❏ 2. Put 5" [127mm] strips of masking tape on the sides of

the fuselage parallel to the fuselage length (two per side) as shown (reference the cowl blocks glued inside the fuselage for placement of the tape). Make a mark 1/4" [6mm] behind the front of the ﬁ rewall on each piece of tape. Use a ruler to accurately draw a 4" [102mm] line from the mark onto the tape. Make a mark at the aft end of each line.

❏ 4. Drill 3/32" [2.4mm] holes at the marks you made on

the cowl through the cowl and fuselage (take care not to drill into the fuel tank). Remove the cowl and thread a #4 x 3/8" [9.5mm] self-tapping screw into each hole in the fuselage and back it out. Apply a couple drops of thin CA to each hole. Enlarge the four holes in the cowl with a 1/8" [3.2mm] bit. Install the cowl onto the fuselage using four #4 x 3/8" [9.5mm] self-tapping screws and four #4 ﬂ at washers.

Page 22

❏ 5. If you haven’t done so already, attach the mufﬂ er to the

engine and connect the vent line from the fuel tank to the mufﬂ er. Trim it to length if needed.

❏ 6. Install your propeller using the prop washer and nut

that came with the motor. Enlarge the propeller slots in the spinner cone as necessary to ﬁ t over the propeller blades. When satisﬁ ed, install the spinner cone onto the backplate using the provided screws.

❏ 8. Install the canopy hatch by ﬁ tting the canopy pins into their

mating holes in the ﬁ rewall, pushing the back of the hatch down against the fuselage, then sliding the hatch back to engage the magnets. You have now completed the assembly!

Apply the Decals

1. Use scissors or a sharp hobby knife to cut the decals from the sheet.

2. Be certain the model is clean and free from oily ﬁ ngerprints and dust. Prepare a dishpan or small bucket with a mixture of liquid dish soap and warm water–about one teaspoon of soap per gallon of water. Submerse the decal in the soap and water and peel off the paper backing. Note: Even though the decals have a “sticky-back” and are not the water transfer type, submersing them in soap and water allows accurate positioning and reduces air bubbles underneath.

❏ 7. To install the wing panels, insert the carbon ﬁ ber wing

joiner into the tube in the fuselage. Slide the wing panels onto the tube, feed the aileron servo leads through the openings in the fuselage side, and align the anti-rotation pins with their mating holes. Bolt the wings in place using the 1/4"-20 nylon wing bolts. Connect the aileron servo leads to the receiver.

3. Position decal on the model where desired. Use the pictures on the box and manual cover for reference. Holding the decal down, use a paper towel to wipe most of the water away.

4. Use a piece of soft balsa or something similar to squeegee remaining water from under the decal. Apply the rest of the decals the same way.

IMPORTANT: If using multiple battery packs that are connected with an adapter, never charge the batteries together through the adapter. Always charge each battery pack separately. Charge the batteries, then read the following precautions on how to connect multiple packs for ﬂ ying the model:

batteries that have a higher voltage. Current will ﬂ ow from the higher voltage battery into the lower one, essentially “charging” the lower voltage battery pack. This situation will likely cause heat and possibly a ﬁ re.

NO!!

BATTERY PRECAUTIONS: There are two ways to connect multiple battery packs: In Series and in Parallel.

These are two 3200mAh batteries (one 11.1V and the other 7.4V). When joined in SERIES, the result will be a 18.5V, 3200 mAh battery.

11.1V (3-Cell) 3200mAh

7.4V (2-Cell) 3200mAh

It’s okay to connect batteries with different voltages in series to achieve the new, desired voltage.

OKAY

This is a SERIES battery adapter (GPMM3143) that connects two batteries in series.

❏ 1. Connecting batteries in “Series” means to connect the

(+)’s to the (–)’s and the (–)’s to the (+)’s. This combines the voltages of the batteries, but the capacity remains the same.

These two 1500mAh batteries (both 11.1V) are being joined in PARALLEL. The result will be one 11.1V, 3000mAh battery.

OKAY

11.1V (3-Cell) 1500mAh

NEVER connect battery packs with different capacities in series or in parallel.

Check the Control Directions

❏ 1. Turn on the transmitter and receiver and center the

trims. If necessary, remove the servo arms from the servos and reposition them so they are centered. Reinstall the screws that hold on the servo arms.

❏ 2. With the transmitter and receiver still on, check all the

control surfaces to see if they are centered. If necessary, adjust the clevises on the pushrods to center the control surfaces.

❏ 3. Make certain that the control surfaces and the throttle

respond in the correct direction as shown in the diagram. If any of the controls respond in the wrong direction, use the servo reversing in the transmitter to reverse the servos connected to those controls. Be certain the control surfaces have remained centered. Adjust if necessary.

Page 24

Set the Control Throws

Use a Great Planes AccuThrow (or a ruler) to accurately measure and set the control throw of each control surface as indicated in the chart that follows. If your radio does not have dual rates, we recommend setting the throws at the low rate setting. Note: The throws are measured at the widest part of the elevators, rudder and ailerons.

Balance the Model (C.G.)

More than any other factor, the C.G. (balance point) can have the greatest effect on how a model ﬂ ies, and may determine whether or not your ﬁ rst ﬂ ight will be successful. If you value this model and wish to enjoy it for many ﬂ ights,

DO NOT OVERLOOK THIS IMPORTANT PROCEDURE.

A model that is not properly balanced will be unstable and possibly unﬂ yable.

At this stage the model should be in ready-to-ﬂ y condition with all of the systems in place including the engine or brushless motor, landing gear, and the radio system (and battery pack if applicable).

❏ 1. Use a felt-tip pen or 1/8" [3mm]-wide tape to accurately

mark the C.G. on the top of the wing on both sides of the fuselage. The C.G. is located 3-3/4" [95mm] back from the leading edge of the wing.

These are the recommended control surface throws:

3D RATE

ELEVATOR

RUDDER

AILERONS

The suggested control throw rates provided in this section may appear to be small in comparison to other aerobatic models similar in size. We do not suggest increasing the rates until after you have made initial ﬂ ights using the provided high rates. Also, it is recommended to add 40% exponential to all control surfaces. This can be changed to suit your ﬂ ying preference after you become accustomed to the ﬂ ight characteristics of the Eagle.

IMPORTANT: The Eagle 580 Matt Chapman .46-.81/EP ARF has been extensively ﬂ own and tested to arrive at the throws at which it ﬂ ies best. Flying your model at these throws will provide you with the greatest chance for successful ﬁ rst ﬂ ights. If, after you have become accustomed to the way the Eagle 580 Matt Chapman .46-.81/EP ARF ﬂ ies, you would like to change the throws to suit your taste, that is ﬁ ne. However, too much control throw could make the model difﬁ cult to control, so remember, “more is not always better.”

This is where your model should balance for the ﬁ rst ﬂ ights. Later, you may wish to experiment by shifting the C.G. up to 1/2" [13mm] forward or 1/4" [6mm] back to change the ﬂ ying characteristics. Moving the C.G. forward may improve the smoothness and stability, but the model may then require more speed for takeoff and make it more difﬁ cult to slow for landing. Moving the C.G. aft makes the model more maneuverable, but could also cause it to become too difﬁ cult to control. In any case, start at the recommended balance point and do not at any time balance the model outside the speciﬁ ed range.

❏ 2. With the wing attached to the fuselage, all parts of the

model installed (ready to ﬂ y) and an empty fuel tank, place the model upside-down on a Great Planes C.G. Machine, or lift it upside-down at the balance point you marked.

❏ 3. If the tail drops, the model is “tail heavy” and the battery

pack and/or receiver must be shifted forward or weight must be added to the nose to balance. If the nose drops, the model is “nose heavy” and the battery pack and/or receiver must be shifted aft or weight must be added to the tail to balance. If possible, relocate the battery pack and receiver to minimize or eliminate any additional ballast required. If additional weight is required, nose weight may be easily added by using a “spinner weight” (GPMQ4645 for the 1 oz. [28g] weight, or GPMQ4646 for the 2 oz. [57g] weight). If spinner weight is not practical or is not enough, use Great Planes (GPMQ4485) “stick-on” lead. A good place to add stick-on nose weight is to the ﬁ rewall

Page 25

(don’t attach weight to the cowl–it is not intended to support weight). Begin by placing incrementally increasing amounts of weight on the bottom of the fuselage over the ﬁ rewall until the model balances. Once you have determined the amount of weight required, it can be permanently attached. If required, tail weight may be added by cutting open the bottom of the fuselage and gluing it permanently inside.

Note: Do not rely upon the adhesive on the back of the lead weight to permanently hold it in place. Over time, fuel and exhaust residue may soften the adhesive and cause the weight to fall off. Use #2 sheet metal screws, RTV silicone or epoxy to permanently hold the weight in place.

❏ 4. IMPORTANT: If you found it necessary to add any weight,

recheck the C.G. after the weight has been installed.

Balance the Model Laterally

❏ 1. With the wing level, have an assistant help you lift the

model by the engine propeller shaft and the bottom of the fuselage under the TE of the ﬁ n. Do this several times.

Balance Propellers

Carefully balance your propeller and spare propellers before you ﬂ y. An unbalanced prop can be the single most signiﬁ cant cause of vibration that can damage your model. Not only will engine mounting screws and bolts loosen, possibly with disastrous effect, but vibration may also damage your radio receiver and battery. Vibration can also cause your fuel to foam, which will, in turn, cause your engine to run hot or quit.

❏ 2. If one wing always drops when you lift the model, it means

that side is heavy. Balance the airplane by adding weight to the other wingtip. An airplane that has been laterally balanced

will track better in loops and other maneuvers.

PREFLIGHT

Identify Your Model

No matter if you ﬂ y at an AMA sanctioned R/C club site or if you ﬂ y somewhere on your own, you should always have your name, address, telephone number and AMA number on or inside your model. It is required at all AMA R/C club ﬂ ying sites and AMA sanctioned ﬂ ying events. Fill out the identiﬁ cation tag on page 31 and place it inside your model.

Charge the Batteries

Follow the battery charging instructions that came with your radio control system to charge the batteries. You should always charge your transmitter and receiver batteries the night before you go ﬂ ying, and at other times as recommended by the radio manufacturer.

CAUTION: Unless the instructions that came with your radio system state differently, the initial charge on new transmitter and receiver batteries should be done for 15 hours using the slow-charger that came with the radio system. This will “condition” the batteries so that the next charge may be done using the fast-charger of your choice. If the initial charge is done with a fast-charger the batteries may not reach their full capacity and you may be ﬂ ying with batteries that are only partially charged.

We use a Top Flite® Precision Magnetic Prop Balancer (TOPQ5700) in the workshop and keep a Great Planes Fingertip Prop Balancer (GPMQ5000) in our ﬂ ight box.

Ground Check

If the engine is new, follow the engine manufacturer’s instructions to break-in the engine. After break-in, conﬁ rm

that the engine idles reliably, transitions smoothly and rapidly to full power and maintains full power–indeﬁ nitely. After you run the engine on the model, inspect the model closely to make sure all screws remained tight, the hinges are secure, the prop is secure and all pushrods and connectors are secure.

Range Check

Ground check the operational range of your radio before the ﬁ rst ﬂ ight of the day. With the transmitter antenna collapsed and the receiver and transmitter on, you should be able to walk at least 100 feet away from the model and still have control. Have an assistant stand by your model and, while you work the controls, tell you what the control surfaces are doing. Repeat this test with the engine running at various speeds with an assistant holding the model, using hand signals to show you what is happening. If the control surfaces do not respond correctly, do not ﬂ y! Find and correct the problem ﬁ rst. Look for loose servo connections or broken wires, corroded wires on old servo connectors, poor solder joints in your battery pack or a defective cell, or a damaged receiver crystal from a previous crash.

ENGINE SAFETY PRECAUTIONS

Failure to follow these safety precautions may result in severe injury to yourself and others.

• Keep all engine fuel in a safe place, away from high heat, sparks or ﬂ ames, as fuel is very ﬂ ammable. Do not smoke near the engine or fuel; and remember that engine exhaust gives off a great deal of deadly carbon monoxide. Therefore,

do not run the engine in a closed room or garage.

• Get help from an experienced pilot when learning to operate engines.

• Use safety glasses when starting or running engines.

• Do not run the engine in an area of loose gravel or sand; the propeller may throw such material in your face or eyes.

• Keep your face and body as well as all spectators away from the plane of rotation of the propeller as you start and run the engine.

• Keep these items away from the prop: loose clothing, shirt sleeves, ties, scarves, long hair or loose objects such as pencils or screwdrivers that may fall out of shirt or jacket pockets into the prop.

• Use a “chicken stick” or electric starter to start the engine. Do not use your ﬁ ngers to ﬂ ip the propeller. Make certain the glow plug clip or connector is secure so that it will not pop off or otherwise get into the running propeller.

• Make all engine adjustments from behind the rotating propeller.

• The engine gets hot! Do not touch it during or right after operation. Make sure fuel lines are in good condition so fuel will not leak onto a hot engine, causing a ﬁ re.

• To stop a glow engine, cut off the fuel supply by closing off the fuel

line or following the engine manufacturer’s recommendations. Do not use hands, ﬁ ngers or any other body part to try to stop the engine. To stop a gasoline powered engine an on/off switch should be connected to the engine coil. Do not throw anything into the propeller of a running engine.

CHECKLIST

FLYING

During the last few moments of preparation your mind may be elsewhere anticipating the excitement of the ﬁ rst ﬂ ight. Because of this, you may be more likely to overlook certain checks and procedures that should be performed before the model is ﬂ own. To help avoid this, a check list is provided to make sure these important areas are not overlooked. Many are covered in the instruction manual, so where appropriate, refer to the manual for complete instructions. Be sure to check the items off as they are completed.

❏ 1. Check the C.G. according to the measurements

provided in the manual.

❏ 2. Be certain the battery and receiver are securely

mounted in the fuselage. Simply stufﬁ ng them into place with foam rubber is not sufﬁ cient.

❏ 3. Extend your receiver antenna. ❏ 4. Balance your model laterally as explained in the

instructions.

❏ 5. Use threadlocking compound to secure critical

fasteners such as the set screws that hold the wheel axles to the struts, screws that hold the carburetor arm (if applicable), screw-lock pushrod connectors, etc.

❏ 6. Add a drop of oil to the axles so the wheels will

turn freely.

❏ 7. Make sure all hinges are securely glued in place. ❏ 8. Reinforce holes for wood screws with thin CA where

appropriate (servo mounting screws, cowl mounting screws, etc.).

❏ 9. Conﬁ rm that all controls operate in the correct direction

and the throws are set up according to the manual.

❏ 10. Make sure there are silicone retainers on all the

clevises and that all servo arms are secured to the servos with the screws included with your radio.

❏ 11. Secure connections between servo wires and

Y-connectors or servo extensions, and the connection between your battery pack and the on/off switch with vinyl tape, heat shrink tubing or special clips suitable for that purpose.

❏ 12. Make sure any servo extension cords you may have

used do not interfere with other systems (servo arms, pushrods, etc.).

❏ 13. Secure the pressure tap (if used) to the mufﬂ er with

high temp RTV silicone, threadlocking compound or J.B. Weld.

❏ 14. Make sure the fuel lines are connected and are

not kinked.

❏ 15. Balance your propeller (and spare propellers). ❏ 16. Tighten the propeller nut and spinner. ❏ 17. Place your name, address, AMA number and telephone

number on or inside your model.

❏ 18. Cycle your receiver battery pack (if necessary) and

make sure it is fully charged.

❏ 19. If you wish to photograph your model, do so before

your ﬁ rst ﬂ ight.

❏ 20. Range check your radio when you get to the ﬂ ying ﬁ eld.

The Eagle 580 Matt Chapman .46-.81/EP ARF is a greatﬂ ying model that ﬂ ies smoothly and predictably. The Eagle does not, however, possess the self-recovery characteristics of a primary R/C trainer and should be ﬂ own only by experienced R/C pilots.

Fuel Mixture Adjustments

A fully cowled engine may run at a higher temperature than an un-cowled engine. For this reason, the fuel mixture should be richened so the engine runs at about 200 rpm below peak speed. By running the engine slightly rich, you will help prevent dead-stick landings caused by overheating.

CAUTION (THIS APPLIES TO ALL R/C AIRPLANES): If, while ﬂ ying, you notice an alarming or unusual sound such as a low-pitched “buzz,” this may indicate control surface ﬂ utter. Flutter occurs when a control surface (such as an aileron or elevator) or a ﬂ ying surface (such as a wing or stab) rapidly vibrates up and down (thus causing the noise). In extreme cases, if not detected immediately, ﬂ utter can actually cause the control surface to detach or the ﬂ ying surface to fail, thus causing loss of control followed by an impending crash. The best thing to do when ﬂ utter is detected is to slow the model immediately by reducing power, then land as soon as safely possible. Identify which surface ﬂ uttered (so the problem may be resolved) by checking all the servo grommets for deterioration or signs of vibration. Make certain all pushrod linkages are secure and free of play. If it ﬂ uttered once, under similar circumstances it will probably ﬂ utter again unless the problem is ﬁ xed. Some things which can cause ﬂ utter are; Excessive hinge gap; Not mounting control horns solidly; Poor ﬁ t of clevis pin in horn; Side-play of wire pushrods caused by large bends; Excessive free play in servo gears; Insecure servo mounting; and one of the most prevalent causes of ﬂ utter; Flying an over-powered model at excessive speeds.

Takeoff

Before you get ready to takeoff, see how the model handles on the ground by doing a few practice runs at low speeds on the runway. Hold “up” elevator to keep the tail wheel on the ground. If necessary, adjust the tail wheel so the model will roll straight down the runway. If you need to calm your nerves before the maiden ﬂ ight, shut the engine down and bring the model back into the pits. Top off the fuel, then check all fasteners and control linkages for peace of mind.

Remember to takeoff into the wind. When you’re ready, point the model straight down the runway, hold a bit of up elevator to keep the tail on the ground to maintain tail wheel steering, and then gradually advance the throttle. As the

Page 28

model gains speed decrease up elevator, allowing the tail to come off the ground. One of the most important things to remember with a tail dragger is to always be ready to apply right rudder to counteract engine torque. Gain as much speed as your runway and ﬂ ying site will practically allow before gently applying up elevator, lifting the model into the air. At this moment it is likely that you will need to apply more right rudder to counteract engine torque. Be smooth on the elevator stick, allowing the model to establish a gentle climb to a safe altitude before turning into the trafﬁ c pattern.

Flight

For reassurance and to keep an eye on other trafﬁ c, it is a good idea to have an assistant on the ﬂ ight line with you. Tell him to remind you to throttle back once the plane gets to a comfortable altitude. While full throttle is usually desirable for takeoff, most models ﬂ y more smoothly at reduced speeds.

improve your skills (though it is never a bad idea!), but more importantly so you do not surprise yourself by impulsively attempting a maneuver and suddenly ﬁ nding that you’ve run out of time, altitude or airspeed. Every maneuver should be deliberate, not impulsive. For example, if you’re going to do a loop, check your altitude, mind the wind direction (anticipating rudder corrections that will be required to maintain heading), remember to throttle back at the top, and make certain you are on the desired rates (high/low rates). A ﬂ ight plan greatly reduces the chances of crashing your model just because of poor planning and impulsive moves. Remember to think.

Have a ball!

But always stay in control and ﬂ y in a safe manner.

GOOD LUCK AND GREAT FLYING!

3D FLYING

Take it easy with the Eagle for the ﬁ rst few ﬂ ights, gradually getting acquainted with it as you gain conﬁ dence. Adjust the trims to maintain straight and level ﬂ ight. After ﬂ ying around for a while and while still at a safe altitude with plenty of fuel, practice slow ﬂ ight and execute practice landing approaches by reducing the throttle to see how the model handles at slower speeds. Add power to see how the model climbs as well. Continue to ﬂ y around, executing various maneuvers and making mental notes (or having your assistant write them down) of what trim or C.G. changes may be required to ﬁ ne tune the model so it ﬂ ies the way you like. Mind your fuel level, but use this ﬁ rst ﬂ ight to become familiar with your model before landing.

Landing

To initiate a landing approach, lower the throttle while on the downwind leg. Allow the nose of the model to pitch downward to gradually bleed off altitude. Continue to lose altitude, but maintain airspeed by keeping the nose down as you turn onto the crosswind leg. Make your ﬁ nal turn toward the runway (into the wind) keeping the nose down to maintain airspeed and control. Level the attitude when the model reaches the runway threshold, modulating the throttle as necessary to maintain your glide path and airspeed. If you are going to overshoot, smoothly advance the throttle (always ready on the right rudder to counteract torque) and climb out to make another attempt. When you’re ready to make your landing ﬂ are and the model is a foot or so off the deck, smoothly increase up elevator until it gently touches down. Once the model is on the runway and has lost ﬂ ying speed, hold up elevator to place the tail on the ground, regaining tail wheel control.

One ﬁ nal note about ﬂ ying your model. Have a goal or ﬂ ight plan in mind for every ﬂ ight. This can be learning a new maneuver(s), improving a maneuver(s) you already know, or learning how the model behaves in certain conditions (such as on high or low rates). This is not necessarily to

Because of the power-to-weight ratio on 3D planes, straightand-level ﬂ ight should be at a reduced throttle and full power should be used only when the airplane is “loaded” during a maneuver. Learn to manage the throttle and experiment while in the maneuver. The power needed will depend on the maneuver being performed. C.G. also plays a large role in the 3D capability of models as well. Experiment, but keep in mind that being tail heavy is not always the best way to go.

Another thing to remember is that maximum control throw is not necessary for all 3D maneuvers. Occasionally, too much throw can place the model too far into a stall, causing it to become uncontrollable. Practice your maneuvers at a higher altitude while you become accustomed to your particular plane’s stall characteristics.

WATERFALLS

With the model pointing vertically (almost in a hover), push full down elevator and full throttle. As the model rotates and begins to point downwards, reduce the throttle (to keep the model from being pulled downwards). As the model ﬂ attens out, add power to pull the model around. Many models will require some rudder correction (usually right rudder) during this maneuver. Some planes will require aileron correction to keep the wings level.

Page 29

UPRIGHT FLAT SPINS

Pull the nose up slightly and slowly decrease power. As the model slows to a few mph, slowly apply full left rudder and power. Next, start adding up elevator as needed to keep the model ﬂ at in the spin. Most airplanes will require some aileron as well to keep the wings level. This is one of the maneuvers to experiment on; try different C.G. positions and different amounts of throw and power to see how ﬂ at the spin will go. It is possible to maintain altitude in the ﬂ at spin and in some cases it is also possible to climb during the spin.

VERTICAL HOVER

Fly a straight pass across the ﬁ eld at 75ft high and 100ft out and pull the model vertical. Roll the model until the top of it is facing you and slowly begin to reduce power. As the model begins to slow down to 10 mph or so, slowly add a little bit of power back in. You will have to adjust the throttle as needed, but make your adjustments smooth. Some right aileron may be needed to keep the model from torque rolling. Use the rudder and elevator to keep the nose pointing straight up. Be patient as this maneuver will take a while to learn.

INVERTED FLAT SPINS

This is the same as the up-right ﬂ at spin except most planes like to spin in the opposite direction, for example: right rudder and down elevator.

THE WALL

Fly straight across the ﬁ eld at a moderate speed and simply pull full up until vertical. Adjust the power as necessary to maintain a hover.

KNIFE EDGE TUMBLE

This is an impressive looking maneuver that really isn’t as difﬁ cult as it looks. (Before learning this maneuver you must be able to conﬁ dently Snap and Tumble your plane and stop the aircraft exactly, without over rotating.) Fly the model Knife Edge from the right at a moderate airspeed, using just enough rudder to maintain Knife Edge, not climbing or diving. Perform one full right negative Tumble by maintaining your rudder setting while applying full throttle, full down elevator, and full right aileron, releasing in time to end again ﬂ ying Knife Edge to the right. Note that you may need to use some positive elevator and/or left aileron to stop the Tumble at exactly Knife Edge. This maneuver is easier to the right because torque helps stop the Tumble and it can be done at varied airspeeds with proper throttle and rudder modulation.

TORQUE ROLL

This is the same as the vertical hover but without the use of right aileron to keep the model from rolling. If needed, you can use a little left aileron to speed the roll up. As the model rotates around, the controls will appear to be reversed to you but only the orientation of the model has changed.

HARRIER

The harrier is nothing more than a high angle of attack ﬂ ying stall. Check the stall characteristics of your plane before proceeding with this maneuver. Bring your plane across the ﬁ eld at 75ft high and 100ft out away from yourself. Slowly pull back on the elevator while reducing throttle. The nose of the plane should come up. Depending on the plane/setup, you may have to make constant aileron (wing walking) and rudder corrections for this maneuver. As the nose of the plane comes up, start adding in a little bit of power to help maintain airspeed. The rudder is now used to turn the model. This maneuver will take some practice as there are a lot of small corrections made to keep most planes in the maneuver.

This is one maneuver where less control is needed. Too much elevator and the model goes into an uncontrollable stall. The C.G. of the plane will have a large effect on the stability of the model during this maneuver. Some planes perform better with more elevator deﬂ ection and a farther forward C.G. while other planes prefer a further aft C.G. and less elevator deﬂ ection. Elevator to ﬂ ap mixing can be used on airplanes with marginal wing area, and some planes won’t stall so elevator to spoileron mixing will be needed.

Page 30

ROLLING HARRIER

Once you get comfortable with the up-right harrier, it’s time to work rolls into the mix. From an up-right harrier, add in left aileron and change from up elevator to down elevator when inverted. If you are comfortable with four point rolls and slow rolls, inputting rudder on the knife edges can improve the maneuver considerably. To turn the model, simply input the elevator or rudder a little sooner or later in the rotation. It’s all a matter of timing.

PINWHEEL

Climb vertically and bring the model to a vertical hover, but do not stop long enough to let the torque pull the model around (climbing or sliding slightly will not be noticeable to spectators but will keep air ﬂ owing over the ailerons and provide you roll authority to stop the torque). When the model is hanging, rock the plane left with rudder, then apply full throttle and full right rudder and hold both, completing 3/4 of a VERY tight Knife Edge Loop and ﬂ ying out Knife Edge. When done correctly, the plane pivots around the wingtip in a very small area. This maneuver can be done in either direction.
