The full-scale Zivko Edge 540T is a great two seat, competition aerobatic trainer. Great Planes has taken the best qualities of the full-scale Edge 540T and reduced it down to a lightweight, 50" electric powered ARF. The Great Planes Edge 540T EP ARF ﬂ ies much like the giant-size Edge’s, but in a much less expensive pac kage. Now you can practice f or IMAC competition without risking your larger, more e xpensive planes.

For the latest technical updates or manual corrections to the Edge 540T EP ARF visit the Great Planes web site at www.greatplanes.com. Open the “Airplanes” link, then select the “Edge 540T 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.

AMA

We urge you to join the AMA (Academy of Model Aeronautics) and a local R/C club. The AMA is the go verning body of model aviation and membership is required to ﬂ y at AMA clubs. Though joining the AMA provides many beneﬁ ts, one of the primary reasons to join is liability protection. Coverage is not limited to ﬂ ying at contests or on the club ﬁ eld. It ev en applies to ﬂ ying at public demonstrations and air shows. Failure to comply with the Safety Code (excerpts printed in the back of the manual) may endanger insurance cov erage . Additionally, training programs and instructors are available at AMA club sites to help you get started the right way. There are over 2,500 AMA chartered clubs across the countr y. Contact the AMA at the address or toll-free phone number below.

IMPORTANT!!! Two of the most important things you can do to preserve the radio controlled aircraft hobby are to avoid ﬂ ying near full-scale aircraft and avoid ﬂ ying near or over groups of people.

PROTECT YOUR MODEL, Y OURSELF

& OTHERS....FOLLOW THESE

IMPORTANT SAFETY PRECAUTIONS

1. Your Edge 540T 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 Edge 540T EP ARF, if not assembled and operated correctly, could possibly cause injury to yourself or spectators and damage to property.

2. Y ou 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 y able model. In a f e w cases the instructions may differ slightly from the photos. In those instances the written instructions should be considered as correct.

DECISIONS YOU MUST MAKE

This is a partial list of items required to ﬁ nish the Edge 540T EP ARF that may require planning or decision making before starting to build.

Radio Equipment

A 4-channel radio system with four micro servos and micro receiver are required for this plane. The servos and receiver shown in the manual are Futaba® S3115 Micro Precision Servo and the Futaba R146iP PCM receiver. For more precision, the Futaba S3150 Slim Digital Servos work great.

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

4. You must use an R/C radio system that is in ﬁ rst-class condition, and a correctly sized motor and components (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. 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 (wheel pant, cowl) 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.

The screw has a diameter of 2mm and a length of 12mm.

• Machine screws are designated by a number, threads per inch, and a length. For example 4-40 x 3/4" [19mm]

ORDERING REPLACEMENT PARTS

This is a number four screw that is 3/4" [19mm] long

with forty threads per inch.

• Socket Head Cap Screws (SHCS) are designated by a number, threads per inch, and a length. For example 4-40 x 3/4" [19mm].

This is a 4-40 SHCS that is 3/4" [19mm] long with forty

• 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.

• We recommend 30-minute epoxy only, because you will need the working time 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.

• The Edge 540T EP ARF is factory-covered with Top Flite® MonoKote® ﬁ lm. Should repairs ever be required, MonoKote can be patched with additional MonoKote purchased separately. MonoKote is packaged in six-foot rolls, but some hobby shops also sell it by the foot. If only a small piece of MonoKote is needed for a minor patch, perhaps a fellow modeler would give you some. MonoKote is applied with a model airplane covering iron, but in an emergency a regular iron could be used. A roll of MonoKote includes full instructions for application. Following are the colors used on this model and order numbers for six foot rolls.

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 6.

❏ 2. Remove the tape and separate the elevators from the

stab. 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. Caution: The Edge 540T EP was designed to be strong where needed, but light weight for excellent ﬂ ight performance. Care must be taken when assembling the plane to avoid damage.

❏ ❏ 3. Tie the string to the servo e xtension. Pull the string and

the servo lead through the wing. Untie the string from the lead.

ASSEMBLE THE WINGS

Install the Ailerons Servos & Pushrods

❏ ❏ 1. Inside the servo bay a string is taped. Carefully

remove the string from the servo bay and tape it to the outside of the wing to prevent it from dropping back into the wing. Test ﬁ t your aileron servo in the servo ba y. Enlarge the opening if required.

❏ ❏ 4. Install the servo into the servo opening. Drill through

the servo mounting holes with a 1/16" [1.6mm] drill bit. Remove the servo from the servo opening. Install and then remove a servo mounting screw into each of the holes you have drilled. Apply a drop of thin CA into the holes to harden the threads. Once the glue has cured install the servo into the servo opening using the servo screws provided with the servo and the 2 x 7 x 9mm servo retaining plates. If your servo uses two screws at each end, do not use the retaining plates. Center the servo and then install a servo arm as shown. The arm should be pointing towards the wingtip.

❏ ❏ 2. Install a 12" [305mm] servo e xtension onto the servo

lead. Secure the extension to the lead with tape, a piece of heat-shrink tubing or some other method to keep them from coming unplugged.

❏ ❏ 5. Thread a nylon clevis, 20 turns, onto a 6" [152mm]

wire pushrod.

HINGE LINE

CORRECT INCORRECT

❏ ❏ 6. Cut the control horn and mounting plate apart. Attach

the clevis in the outer hole of a nylon control horn. Place the control horn in line with the hole 3/4" [19mm] from the center of the servo arm. When positioned properly the control horn will rest on a hardwood plate in the aileron. Mark the location of the mounting holes onto the aileron. Drill a 3/32" [2.4mm] hole on the marks, drilling through the plywood plate and the top of the aileron.

pushrod where it crosses the aileron servo arm. Make a 90° bend at the mark. Cut the pushrod 3/8" [9.5mm] past the bend. Attach the pushrod to the aileron servo arm with a nylon FasLink.

❏ ❏ 9. Glue the carbon ﬁ ber anti rotation pin in the hole as

shown. The pin should protrude approximately 1/4" [6.4mm].

❏ 10. Repeat steps 1 to 9 for the left wing panel.

ASSEMBLE THE FUSELAGE

Install the Main Landing Gear

❏ ❏ 7. Insert two 2-56 x 5/8" [16mm] machine screws

through the control horn and aileron. Secure the control horn to the aileron with the nylon control horn backplate.

❏ ❏ 8. Slide a silicone clevis retainer over the clevis. With

the aileron servo and the aileron centered, mark the aileron

❏ ❏ 1. Insert a 4mm axle through the right main landing

gear. Secure the axle to the landing gear with a 5mm ﬂ at washer and 5mm lock nut. Note: The front of the main landing gear sweeps forward.

❏ ❏ 2. Install two 5mm ﬂ at washers on the axle, then the

foam main wheel, followed by a 4.2mm wheel collar. Secure the wheel collar on the axle with 6-32 set screw. Mark the

location where the set screw tightens on the axle and use a metal cutting ﬁ le to ﬁ le a ﬂ at spot on the axle. Apply a drop of threadlocker on the set screw and reinstall the wheel collar on the axle.

❏ ❏ 3. Position the right wheel pant over the wheel and

secure it to the main landing gear with two 2-56 x 3/8" [9.5mm] machine screws, 2mm ﬂ at washers and 2mm lock washers.

❏ 1. Glue the nylon tail gear bushing in the hole in the aft

bottom of the fuselage.

❏ ❏ 4. Attach the main landing gear to the fuselage with

three 4-40 x 1/2" [12.7mm] SHCS, 3mm lock washers and 3mm ﬂ at washers.

❏ 5. Repeat steps 1 to 4 for the left main landing gear.

Install the Tail Gear

❏ 2. Insert the tail gear wire through the aluminum tail gear

bracket. Inser t the tail gear wire and bracket in the tail gear bushing. With the tail gear bracket aligned with the bottom of the fuselage, mark and drill a 1/16" [1.6mm] pilot hole at both tail gear bracket mounting hole locations. Secure the tail gear bracket to the fuselage with two 2 x 12mm sheet metal screws.

❏ 3. Thread a 4-40 set screw into the 2.5mm wheel collar.

Remove the tail gear wire from the tail gear bracket and position the 2.5mm wheel collar under the bracket. Slide the

nylon tail gear post onto the thin tail gear wire. Insert the tail gear wire through the aluminum tail gear bracket and wheel collar while inserting the tail gear post in the bottom of the rudder. Tighten the set scre w in the wheel collar and glue the tail gear post in the rudder with thin CA.

❏ 4. Install the tail wheel on the tail gear wire and press the

silicone retainer on the tail gear wire to secure the tail wheel.

❏ 2. Center the horizontal stabilizer in the slot in the fuselage.

Stand back and look at the stab in relation to the wing. The stab should be parallel with the wing. If not, sand the stab saddle until the stab and wings are aligned.

Install the Stabilizer

❏ 3. Measure the distance from the tip of the stab to the

center of the fuselage. Adjust the position of the stab until they are equal. The stringer is centered in the front of the fuselage.

❏ 1. Center the wing tube in the fuselage. Slide the wing

halves onto the wing tube and secure the wing halves to the fuselage with the nylon 10-24 thumb screws. Be careful putting pressure on the wing and fuselage. The wings may be tight the ﬁ rst time they are slid on the tube.

❏ 4. Using a ﬁ ne-point felt-tip pen, mark the outline of the

fuselage on the top and the bottom of the stab.

❏ 5. Cut the covering on the top and bottom of the stab

inside the line you have drawn. Use care to cut only into the covering and not into the wood.

HOW TO CUT COVERING FROM BALSA

Use a soldering iron to cut the covering from the area beneath the wing bolt plate. The tip of the soldering iron doesn’t have to be sharp, but a ﬁ ne tip does work best. Allow the iron to heat fully.

Use a straightedge to guide the soldering iron at a rate that will just melt the covering and not burn into the wood. The hotter the soldering iron, the faster it must travel to melt a ﬁ ne cut. Peel off the covering.

30-minute epoxy to the wood, top and bottom. Slide the stab through the fuselage so that approximately 1/2" [12.7mm] of bare wood is showing on the other side and apply epoxy to the wood. Now align the stab, remove the masking tape and wipe off any excess epoxy from the stab and fuselage. Recheck that the stab is still aligned.

You can now remove the wings and continue with the assembly of the fuselage.

Install the Elevator Hinges

❏ ❏ 1. Drill a 3/32" [2.4mm] hole, 1/2" [12.7mm] deep in the

center of each hinge slot to allow the CA to “wick” in. Followup with a #11 blade to clean out the slots. Hint: If you have one, use a high-speed rotary tool to drill the holes.

❏ 6. Wipe away the lines you drew. Insert the elevator

joiner wire in the notch at the back of the stab saddle.

Use epoxy to glue the stab in place, being careful that the stab is properly aligned.

Tip: Place a piece of masking tape on the top and bottom of the stabilizer, just outside the cut covering. Insert the stab in the fuselage so that part of the bare wood is showing. Apply

❏ ❏ 2. Use a sharp #11 blade to cut a strip of cov ering from

the hinge slots in the wing and aileron.

1" [25mm]

3/4" [19mm]

Trim the Corners

❏ ❏ 3. Cut six 3/4" x 1" [19 x 25mm] hinges from a CA

hinge strip. Snip off the corners so they go in easier. Inser t three hinges in each elevator.

❏ ❏ 4. Test ﬁ t the ele vators to the stab with the hinges . If the

hinges don’t remain centered, stick a pin through the middle of the hinge to hold it in position.

Install the Elevators

❏ 1. Install the RimFire motor using four 4-40 x 1/2" [12.7mm]

SHCS, four 3mm lock washers and four 3mm ﬂ at washers. Before installing, apply a drop of threadlock er to the threads of the SHCS.

❏ 2. Connect the ESC to the motor . The ESC can be attached

to the side of the motor box with hook and loop material.

❏ 1. Install the elevators onto the stab with the elevator

joiner wire in each elevator half. Check that both elevator halves are aligned. If not, remove the elevators and while holding one leg of the elevator joiner wire, slightly bend the other. Reinstall the elevator halves and check again.

❏ 2. Coat the inside of the two elevator joiner wire holes and

the ends of the elevator joiner wire with epo xy. Install the tw o elevator halves, remove the pins and glue the hinges with thin CA.

Install the Motor

The Edge 540T EP has been designed to use the Great Planes RimFire 42-50-800 Out-runner Brushless motor. If you will be installing a different motor, you may need to modify the plywood motor box.

❏ 3. Use hook and loop material to mount the receiver in the

fuselage. The antenna can be routed out the bottom of the fuselage and taped to the covering.

INSTALL THE RADIO SYSTEM

Install the Elevator Servo

❏ 1. Cut the covering away from the lower opening on the

left side, in the rear of the fuselage for the elevator servo.

❏ 2. Install a 16" [406mm] servo extension to the elevator

servo. Secure the extension to the lead with tape, a piece of heat-shrink tubing some other method to keep them from coming unplugged.

❏ 5. Slide a silicone clevis retainer over the clevis. With the

elevator servo and the elevator centered, mark the elevator pushrod where it crosses the elevator servo arm. Make a 90° bend at the mark. Cut the pushrod 3/8" [9.5mm] past the bend. Attach the pushrod to the elevator ser vo arm with a nylon FasLink.

Install the Rudder Servo

❏ 3. Install the elevator servo into the servo openings. Drill

through the servo mounting holes with a 1/16" [1.6mm] drill bit. Remove the servo from the servo opening. Install and then remove a servo mounting screw into each of the holes you have drilled. Apply a drop of thin CA into the holes to harden the threads. Once the glue has hardened install the servo into the servo opening using the 2 x 7 x 9mm servo retaining plates. Center the servo and then install a servo arm with a hole 3/4" [19mm] from the center.

Now is the time you need to decide on which rudder control method you are going to use. Unless you are installing a heavy motor , we recommend that you use the pull-pull system to keep the weight out of the tail. To help you decide you can install the wing, cowl and canopy. Mark the C.G. location on the wing (shown on page 18). Then, place the plane on a C .G. stand and position the ﬂ ight battery in the middle of the battery tray. If the plane is slightly tail heavy, we recommend that the rudder pull-pull system be installed. If the plane is nose heavy, the rudder servo can be installed in the tail.

Rudder Pull-Pull Installation

❏ 4. Thread a nylon cle vis 16 turns onto a 2-56 x 6" [152mm]

wire pushrod. Connect the cle vis to the second hole from the base of a nylon control horn. Using the elevator pushrod, position the control horn in line with the servo arm. When positioned properly the control horn will rest on a hardwood plate in the elevator. Mark the location of the mounting holes onto the elevator. Drill a 1/16" [1.6mm] hole on the marks, drilling through the elevator. Attach the control horn to the elevator using two 2-56 x 3/4" [19mm] machine screws.

❏ 1. Install the rudder servo centered in the rudder pull-

pull servo tray. Drill through the servo mounting holes with a 1/16" [1.6mm] drill bit. Remove the servo from the servo opening. Install and then remove a servo mounting screw into each of the holes you have drilled. Apply a drop of thin CA into the holes to harden the threads. Once the glue has hardened install the servo into the servo opening using the 2 x 7 x 9mm servo retaining plates. Center the servo, and then install a servo arm as shown.

❏ 2. Cut the covering from over the two pull-pull exits at the

aft end of the two servo openings, between the openings.

❏ 3. Cut the pull-pull string in half. Put a small drop of thin

CA on one end of each piece of string. Allow the CA to cure and trim off any frayed thread. Insert the end into the pull-pull guide tubes in the fuselage. The string ma y be difﬁ cult to guide through the exit. Once the str ing will not go any further into the tube, use the point of a hobby knife to help pull the string through the exit. Tape the str ing to the side of the fuselage at the aft end to prevent it from being pulled through.

❏ 5. Insert the 2mm threaded rudder control horn rod. Center

the rod in the rudder with two 2mm ﬂ at washers and 2mm nuts on each side. A drop of threadlocker on the threads will help prevent the nuts from coming loose.

❏ 6. Thread a nylon torque rod horn onto each end of the

control horn rod. Adjust the torque rod horn so that they are both equal distance from the rudder.

❏ 4. Measure up 3/4" [19mm] from the bottom of the rudder

and make a mark. Measure in from the leading edge 1/4" [6.4mm] and make a mark. Drill a 3/32" [2.4mm] hole through the rudder, perpendicular to the centerline of the rudder.

❏ 7. Thread 2-56 nuts onto four 2-56 rigging couplers.

Slide a silicone clevis retainer ov er four threaded 2-56 metal clevises. Then, thread the clevises 10 turns onto the rigging couplers. Tighten the 2-56 nuts against the metal clevises.

❏ 8. Working from the end of the string inside the fuselage,

pass the string through a crimp, through the rigging coupler and back through the crimp. Squeeze the crimp with a pliers to secure the string in the crimp. Apply a drop of thin CA to the crimp.

Rudder Servo Installation in the Tail

❏ 1. Cut the covering away from the upper opening on the

right side, in the rear of the fuselage for the rudder servo.

❏ 2. Install a 16" [406mm] servo extension on the rudder

servo. Secure the extension to the lead with tape, a piece of heat-shrink tubing or some other method to keep them from coming unplugged.

❏ 9. Attach the cle vises to the rudder servo horn in the holes

3/4" [19mm] from the center.

❏ 10. Pull the pull-pull string out of the fuselage aft end

so that the string is tight. Pass the string through a crimp, through the rigging coupler and back through the crimp. Attach the clevis to the nylon torque rod horn on the rudder and tape the string to the side of the fuselage. Repeat on the other side of the fuselage.

❏ 11. With the rudder and the rudder ser vo arm centered,

pull the string tight at the rudder and squeeze the crimps to secure the strings.

❏ 3. Install the rudder servo into the servo opening. Drill

❏ 4. Thread a nylon clevis 16 turns onto a 2-56 x 6"

[150mm] wire pushrod. Connect the clevis to the second hole from the base of a nylon control horn. Using the rudder pushrod, position the control horn in line with the servo arm.

When positioned properly the control horn will rest on a hardwood plate in the rudder. The center of the control horn is approximately 5/8" [16mm] from the bottom of the rudder. Mark the location of the mounting holes onto the rudder. Drill a 1/16" [1.6mm] hole on the marks. Do not drill completely through the rudder. Attach the control horn to the rudder using two 2-56 x 3/4" [19mm] machine screws. Remove the screws and apply a drop of thin CA to both holes. After the CA has cured, reinstall the control horn.

❏ 5. Slide a silicone clevis retainer over the clevis. With

the rudder servo and the rudder centered, mark the rudder pushrod where it crosses the rudder servo arm. Make a 90° bend at the mark. Cut the pushrod 3/8" [9.5mm] past the bend. Attach the pushrod to the rudder servo arm with a nylon FasLink.

❏ 6. Connect the ESC, voltage regulator, rudder servo,

elevator servo and Y-harness to the receiver.

❏ 7. Connect the ﬂ ight battery to the ESC and voltage

regulator. Check that all the servos are operating correctly. Arm the motor (with the prop removed) and slowly start the motor to make sure it is rotating in the correct direction.

through the slot in the battery tray, under the tray and back through the slot on the other side of the tray.

❏ 9. Attach a strip of sticky backed hook material to the

center of the battery tray. The loop material can be attached to the battery.

Apply the Decals

The box photographs show the location of the decals on the airplane. Refer to the box for the exact placement of the decals. The following tips may be useful for applying them.

1. 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.

❏ 8. Overlap by 1" [25mm] two strips of non adhesive bac ked

hook and loop material. Route the hook and loop material

2. Position decals on the model. Holding the decal down, use a paper towel to wipe most of the water away.

3. 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.

GET THE MODEL READY TO FLY

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 ser vos connected to those controls. Be certain the control surfaces have remained centered. Adjust if necessary.

These are the recommended control surface throws:

HIGH RATE

ELEVATOR: 3/4" [19mm], 12° up

3/4" [19mm], 12° down RUDDER: 3-1/2" [89mm], 30° left

3-1/2" [89mm], 30° right AILERONS: 3/4" [19mm], 15° up

3/4" [19mm], 15° down

LOW RATE

ELEVATOR: 1/2" [13mm], 8° up

1/2" [13mm], 8° down RUDDER: 2" [51mm], 17° left

2" [51mm], 17° right AILERONS: 1/2" [13mm], 10° up

1/2" [13mm], 10° down

3D RATE

ELEVATOR: 2-1/2" [64mm], 42° up

2-1/2" [64mm], 42° down RUDDER: 5" [127mm], 45° left

5" [127mm], 45° right AILERONS: 1-3/4" [44mm], 40° up

1-3/4" [44mm], 40° down

Set the Control Throws

Use 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 hav e dual rates, we recommend setting the throws at the low rate setting.

We also put exponential into the high r ates and the 3D rates to make the control throws less sensitive around neutral. These can be set up to your own preference and ﬂ ying style. We put 20% to 30% in the high rate and 50% to 60% in the 3D rates.

IMPORTANT: The Edge 540T EP 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 Edge 540T EP 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.”

Note: The throws are measured at the widest part of the elevators, rudder and ailerons.

FINISH THE MODEL

❏ 1. The cowl is held on with four magnets. It ﬁ ts over the

small lip and snaps into place. Note: If you will be perf orming violent maneuvers, a piece of clear tape should be applied to both sides of the cowl to help hold it in place.

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

mark the C.G. on the top of the wing at the side of the fuselage. The C.G. is located 2-13/16" [71mm] back from the leading edge of the wing at the side of the fuselage.

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 3/16" [5mm] forward or 3/16" [5mm] 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 tak eoff and mak e 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. Use a prop reamer or drill bit to enlarge the spinner

backplate to ﬁ t your motor’s prop adapter. Install the spinner backplate, propeller with washer and prop nut and the spinner cone. Secure the spinner cone to the backplate with two 3 x 10mm sheet metal screws.

❏ 3. Insert a ﬂ ight battery in the fuselage and use the hook

and loop material to hold the battery in position. Do not connect the battery to the ESC while balancing the model.

❏ 4. Install the canopy.

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 enjo y it for man y ﬂ ights,

DO NOT OVERLOOK THIS IMPORTANT PROCEDURE.

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

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

model installed (ready to ﬂ y), lift the model 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 must be shifted aft or weight must be added to the tail to balance. If additional weight is required, use Great Planes (GPMQ4485) “stick-on” lead. A good place to add stick-on nose weight is to the motor box (don’t attach weight to the cowl–it is not intended to support weight). Begin by placing incrementally increasing amounts of weight on the fuselage over the motor box until the model balances. Once y ou hav e determined the amount of weight required, it can be permanently attached.

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

At this stage the model should be in ready-to-ﬂ y condition with all of the systems in place including the motor, landing gear, covering and paint, and the radio system.

Balance the Model Laterally

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

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

❏ 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 Y our Model

No matter if you ﬂ y at an AMA sanctioned R/C club site or if you ﬂ y some where on your o wn, you should alw ays ha ve y our 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 22 and place it on or inside your model.

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 motor mounting screws and bolts loosen, possibly with disastrous effect, but vibration may also damage your radio receiver and battery.

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.

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 batteries the night before you go ﬂ ying, and at other times as recommended by the radio manuf acturer .

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 y our choice . If the initial charge is done with a fast-charger the batteries may not reach their full capacity and you ma y be ﬂ ying with batteries that are only partially charged.

Range Check

Ground check the operational range of your r adio 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 [30m] 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 motor 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. The problem may be the location of the antenna. The antenna should be as far away from the ESC and battery as possible.

MOTOR SAFETY PRECAUTIONS

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

Get help from an experienced pilot when learning to operate electric motors.

Use safety glasses when running electric motors.

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

Keep your f ace and body as w ell as all spectators a wa y from the plane of rotation of the propeller as you run the motor.

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

Radio Control

1) I will have completed a successful radio equipment ground check before the ﬁ rst ﬂ ight of a new or repaired model.

2) I will not ﬂ y my model aircraft in the presence of spectators until I become a qualiﬁ ed ﬂ ier, unless assisted by an experienced helper.

The motor gets hot! Do not touch it during or right after operation.

When working on your plane, remove the propeller if the motor battery will be connected.

Always remove the motor battery from the plane when charging.

Follow the charging instructions included with your charger for charging LiP o batteries. LiPo batteries can cause serious damage if misused.

AMA SAFETY CODE (excerpts)

Read and abide by the following excerpts from the Academy of Model Aeronautics Safety Code. For the complete Safety Code refer to Model A viation magazine, the AMA web site or the Code that came with your AMA license.

General

1) I will not ﬂ y my model aircraft in sanctioned events, air sho ws,

or model ﬂ ying demonstrations until it has been proven to be airworthy by having been pre viously, successfully ﬂ ight tested.

2) I will not ﬂ y my model aircraft higher than approximately

400 feet within 3 miles of an airport without notifying the airport operator. I will give right-of-wa y and av oid ﬂ ying in the proximity of full-scale aircraft. Where necessary, an observer shall be utilized to supervise ﬂ ying to avoid having models ﬂ y in the proximity of full-scale aircraft.

3) Where established, I will abide by the safety rules for the

ﬂ ying site I use, and I will not willfully and deliberately ﬂ y my models in a careless, reckless and/or dangerous manner.

5) I will not ﬂ y my model unless it is identiﬁ ed with my name

and address or AMA number, on or in the model. Note: This does not apply to models while being ﬂ own indoors.

7) I will not operate models with pyrotechnics (any device

that explodes, burns, or propels a projectile of any kind).

3) At all ﬂ ying sites a straight or curved line(s) must be established in front of which all ﬂ ying takes place with the other side for spectators. Only personnel involved with ﬂ ying the aircraft are allowed at or in the front of the ﬂ ight line. Intentional ﬂ ying behind the ﬂ ight line is prohibited.

4) I will operate my model using only radio control frequencies currently allowed by the F ederal Communications Commission.

5) I will not knowingly operate my model within three

miles of any pre-existing ﬂ ying site except in accordance with the frequency sharing agreement listed (in the

complete AMA Safety Code).

9) Under no circumstances may a pilot or other person touch a powered model in ﬂ ight; nor should any part of the

model other than the landing gear, intentionally touch the ground, except while landing.

CHECK LIST

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. Man y 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 and make sure it has a

strain relief inside the fuselage to keep tension off the solder joint inside the receiver.

❏ 4. Balance your model laterally as explained in

the instructions.

❏ 5. Use threadlocking compound to secure critical

fasteners such as the motor screws, wheel collar SHCS and 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, control horn 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 with vinyl tape, heatshrink 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. Balance your propeller (and spare propellers). ❏ 14. Tighten the propeller nut and spinner. ❏ 15. Place your name, address, AMA number and telephone

number on or inside your model.

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

your ﬁ rst ﬂ ight.

❏ 17. Range check your radio when y ou get to the ﬂ ying ﬁ eld.

Takeoff

Before you get ready to takeoff, see how the model handles on the ground by doing a fe w 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 y ou need to calm your nerves before the maiden ﬂ ight bring the model back into the pits, peak the battery and 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 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 motor 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 lik ely that you will need to apply more right rudder to counteract motor 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.

FLYING

The Edge 540T EP is a great-ﬂ ying model that ﬂ ies smoothly and predictably. The Edge 540T EP 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.

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 saf ely 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.

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. The Edge 540T EP with the recommended power system will only require full throttle in short burst. Most aerobatic ﬂ ight can be performed at around 1/2 throttle. If you observe the ﬂ ight of some of the best aerobatic pilots, they very seldom use full throttle.

T ake it easy with the Edge 540T EP for the ﬁ rst ﬂ ight, 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 battery, 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 she 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 battery power level, b ut use this ﬁ rst ﬂ ight to become familiar with your model before landing. With most electric planes it is best to have a timer set on your transmitter or a separate timer with an alarm to alert you when the batter y may be getting low. This will require a few ﬂ ights before determining the maximum ﬂ ight time you can achieve with the batteries. This will prevent the downwind auto motor cutoff over the end of the ﬂ ying ﬁ eld. With the plane properly trimmed you will want to get started with some aerobatics. This plane is

capable of just about every aerobatic maneuver you can do. Become familiar with the high and low rate settings before using the 3D rates. If you have not ﬂ own an airplane with 3D rates you should work your way into these higher 3D rates cautiously. The extreme throws can stall the air plane if you are not careful. Over controlling could also result in unwanted snaps. If you have not ﬂ own 3D you might want to consider getting help from an experienced 3D pilot. When executing down line maneuvers it is important to use good throttle management. Full power down lines could result in over stressing of the aircraft.

Make a copy of this identiﬁ cation tag and put it on or inside your model.

Landing

To initiate a landing approach, lower the throttle while on the downwind leg. Allow the nose of the model to pitch do wnw ard to gradually bleed off altitude. Continue to lose altitude, but maintain airspeed by keeping the nose down as y ou turn onto the crosswind leg. Make your ﬁ nal turn tow ard the runway (into the wind) keeping the nose down to maintain airspeed and control. Le vel the attitude when the model reaches the runwa y 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 do wn. Once the model is on the runway and has lost ﬂ ying speed, hold up ele vator 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 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 y our 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

Because of the power-to-weight ratio on 3D planes, str aightand-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.

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.

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 e xample: 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 y ou 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.

ROLLING HARRIER

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 str aight up . Be patient as this maneuver will take a while to learn.

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 either direction.
