The full-size Seawind is manufactured by Seawind/S.N.A., Inc. It was designed as the world’s best and fastest 4 or 5 place amphibian. It has a cruising speed of 190+ mph, allowing pilots to reach their destination quickly and comfortably. Being able to take-off and land from water or land opens up many destinations not possible with land based only planes.
Great Planes has now taken this great flying plane and developed a .60-size ARF. Now you too can fly from land or water, opening up new flying sites not available before. Many hours of development and test flying have gone into the Great Planes Seawind ARF to create an easy to build and fly amphibious plane. Whether you’re an experienced float plane pilot or new to this segment of the hobby, we at Great Planes think you will be very pleased with the Seawind ARF.
For the latest technical updates or manual corrections to the Great Planes Seawind ARF, visit the Great Planes web site at
www.greatplanes.com
. Open the “Airplane” link, then select the Seawind 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.
We urge you to join the AMA (Academy of Model Aeronautics) and a local R/C club. The AMA is the governing body of model aviation and membership is required to fly at AMA clubs. Though joining the AMA provides many benefits, one of the primary reasons to join is liability protection. Coverage is not limited to flying at contests or on the club field. It even applies to flying at public demonstrations and air shows.Failure to comply with the Safety Code (excerpts printed in the back of the manual) may endanger insurance coverage. 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 flying near full-scale aircraft and avoid flying near or over groups of people.

Though the Great Planes Seawind is an ARF and may not have the same level of detail as an “all-out” scratch-built competition model, it is a scale model nonetheless and is therefore eligible to compete in the
Fun Scale
class in AMA competition (we receive many favorable reports of Great Planes ARFs in scale competition!).In Fun Scale, the “builder of the model” rule does not apply.To receive the five points for scale documentation, the only proof required that a full-size aircraft of this type in this paint/markings scheme did exist is a single sheet such as a kit box cover from a plastic model, a photo, or a profile painting, etc. If the photo is in black and white other written documentation of color must be provided. Contact the AMA for a rule book with full details.
1. Your Great Planes Seawind 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 Seawind 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 unflyable 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.
4. You must use an R/C radio system that is in first-class condition, and a correctly sized engine and components 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 flight 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 flown this type of model before, we recommend that you get the assistance of an experienced pilot in your R/C club for your first flights. 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 flight tested to exceed normal use, if the plane will be used for extremely high-stress flying 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, canopy, wing tips and fuselage in this kit are made of fiberglass, the fibers of which may cause eye, skin and respiratory tract irritation. Never blow into a part (cowl) to remove fiberglass 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 fiberglass parts. Vacuum the parts and the work area thoroughly after working with fiberglass parts.
Remember:Take your time and follow the instructions to end up with a well-built model that is straight and true.
This is a partial list of items required to finish the Seawind ARF that may require planning or decision making before starting to build. Order numbers are provided in parentheses.
For the basic setup to fly off of water the Seawind ARF requires:
5-Channel radio (3) Micro servos with metal gears S3102 (FUTM0034)
for rudder, throttle and elevator
(4) Standard Ball Bearing servos S9001 (FUTM0075)
for (2) aileron (2) flaps
(1) 12" [300mm] Servo extension (HCAM2711
for Futaba®)
(7) 36" [910mm] Servo extension (HCAM2726
for Futaba)
(2) Y-harness (HCAM2751 for Futaba)
Option 1: If the included fixed landing gear is installed, a fifth S9001 (FUTM0075) servo and a third Y-harness (HCAM2751) will be required for the nose steering.
Option 2: If the optional retracts are installed, a 6-channel radio and a Standard S3003 servo (FUTM0031) to operate the retract air valve are required.
Radio Equipment
DECISIONS YOU MUST MAKE
We, as the kit manufacturer, provide you with a top quality, thoroughly tested kit and instructions, but ultimately the quality and flyability of your finished 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.

If you would prefer to set the Seawind ARF up with flaperons, a 7-channel radio will be required.
The recommended engine size range for the Seawind ARF is .60 cu in [10cc] two-stroke, .70 – .91 cu in [11.5 – 15cc] four­stroke. Because of the limited clearance between the engine and fuselage, a 3-bladed propeller is required. A 3-bladed spinner is included in the kit.
The Seawind ARF can be built three ways.If it will be flown off of water, no landing gear is required.If the Seawind ARF will be flown from land, it comes with fixed landing gear. The third option is to install retracts.The Robart retracts (ROBQ1622) are recommended. Along with the retracts you will need the #188VRX Complete Standard Air Kit (ROBQ2307) and #190 Air Line Quick Disconnect (ROBQ2395). All three options are covered in the instruction manual.
This is the list of hardware and accessories required to finish the Seawind ARF. Order numbers are provided in parentheses.

When you see the term
test fit
in the instructions, it means that you should first position the part on the assembly without using any glue, then slightly modify or
custom fit
the part as necessar y for the best fit.
Whenever the term
glue
is written you should rely upon your experience to decide what type of glue to use.When a specific type of adhesive works best for that step, the instructions will make a recommendation.
Whenever just
epoxy
is specified you may use either 30-minute (or 45-minute) epoxy or 6-minute epoxy. When 30-minute epoxy is specified 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.

The Great Planes Seawind ARF is factory-covered with Top Flite MonoKote film. 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 giv e 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 is the color used on this model and order number for a six foot roll.
White – TOPQ0204

1. Remove the two styrofoam airplane stand ends and the
two 1-5/8" x 27-1/2" [41 x 660mm] plastic tubes. Slide the tubes into the two ends.
We are going to install the engine in the upright position first to prevent damaging other components of the plane while maneuvering the plane around.
1. Cut the “spreader bar” from the supplied Great Planes
engine mount. Use a hobby knife to remove any flashing left over from the molding process so that the halves fit together well.
2. Temporarily attach the engine mount upright to the
firewall using four 8-32 x 1" [4 x 25.4mm] socket-head cap screws, four #8 flat washers and four #8 lock washers.
3.Position the engine on the engine mount so that the front
of the drive washer (or back of the spinner) is 5-1/8" [130mm] from the firewall.Also make sure the engine is centered on the engine mount.
4. Use a Great Planes Dead Center
hole locator to mark
on the engine mount the four engine mounting holes.
5. Remove the engine mount and use a drill press, if you
have one, to drill a 9/64" [3.5mm] hole at each mark, perpendicular to the engine mount rails. Then, tap all four holes with an 8-32 [6mm] tap.
6. Using four 8-32 x 1" [6 x 25.4mm] socket-head cap
screws, four #8 lock washers and four #8 flat washers, install the engine on the engine mount.
7. Remove the four 8-32 [4mm] socket-head cap screws
from the engine mount and rotate the mount 180 degrees so that the engine is mounted inverted. Be sure to use thread­lock on the 8-32 [4mm] socket-head cap screws when reinstalling them.
1. Inser t the 11-3/4" [298mm] gray outer pushrod tube in
the fuel tank compartment through the formers as shown. Note the location that the pushrod tube hits the back of the firewall.This will give you an idea where the pushrod must e xit the firewall to allow smooth operation.

2.Drill a 3/16" [4.8mm] hole through the front of the firewall.
Roughen the outer pushrod with sandpaper. Inser t the outer pushrod tube through the firewall and the former so that it protrudes through the first former by approximately 1" [25.4mm].Trim the excess flush with the front of the firewall.
3. Install a screw-lock pushrod connector on the throttle
arm and secure it with a nylon keeper.
1.Remove the components from inside the fuel tank.Install
the three aluminum tubes in the fuel tank stopper. You will need to use a hobby knife to open the third hole in the rubber stopper.Slide the small metal plate over the tubes and thread the screw into the plate until it makes contact with the back of the rubber stopper.Do not tighten the screw.
2. Carefully bend one of the long tubes so that it will angle
up toward the top of the fuel tank when inserted. Do not kink the tube. Mark a “P” on the outside of the front plate to designate pressure.
3. Install a piece of fuel tubing on each of the other two
tubes. Attach a clunk on the ends of the tubes. Mar k a “C” on the outside of the front plate by the short tube, designating carb, and an “F” by the remaining tube, designating fill.
4. Inser t the tank stopper in the fuel tank. Check that the
two clunks are able to move freely when the stopper is inserted completely.Then, tighten the screw in the stopper to seal the fuel tank.Write “top” on the side of the fuel tank where the pressure tube sticks up.
5.Install three pieces of fuel line on the three aluminum fuel
tubes in the front of the fuel tank. Inser t the fuel tank into the fuel tank compartment, routing the fuel line out of the firewall. Make sure the top of the tank faces upward.
6. Connect the correct fuel line to the carburetor and the
fuel line plug to the fill line.The pressure line will be connected to the muffler once the cowl has been installed.

1. Position the Micro servo with the top of the servo case
flush and centered with the edge of the throttle servo tray. Use epoxy to glue the two hardwood servo tray blocks on each side of the servo against the servo mounting flanges.
2. Once the glue has cured, remove the servo, turn the
servo tray ov er and drill a 1/16" [1.6mm] pilot hole through the servo tray and into the servo tray blocks, centered in the blocks.Secure the servo tra y blocks to the servo tray with tw o #2 x 3/8" [9.5mm] self-tapping screws.
3. Attach the 1" x 1" [25.4 x 25.4mm] double-sided tape to
the servo tray, between the servo tray blocks.Then attach the throttle servo to the tape.
4. Position the plywood servo retainer over the servo and
drill a 1/16" [1.6mm] pilot hole at each end through the retainer and into the servo tray block.
5. Connect a 36" [914mm] ser vo extension to the throttle
servo.Tie the string in the fuel tank compartment to the end of the extension and pull the extension through the tube and into the fuselage.Tape or heat-shrink the leads together.
6.Insert the throttle pushrod in the pushrod tube.Insert the
Z-Bend in the throttle servo horn. Position the throttle servo in the fuel tank compartment.
7.Use a pliers to bend the throttle pushrod so that it can be
inserted in the screw-lock pushrod connector. Cut off the excess pushrod and secure the pushrod in the screw-lock pushrod connector with a 4-40 set screw.
8. Use epoxy to glue the throttle servo tray in the fuel
tank compartment.

2. Use epoxy to glue the rudder base to the bottom of
the rudder. Make sure the epoxy covers all of the bare wood surfaces.
3. Cut and install three hinges in the rudder. Install the
rudder on the fuselage following the same procedure used to install the elevator.
4. Install a 1/8" [3mm] set screw in the water rudder
control rod.
5.Insert the water rudder control rod in the quick connector
on the bottom of the rudder. Inser t the water rudder in the fuselage and connect the water rudder control rod to the water rudder. Do not trim off the excess control rod until after the rudder throws have been set.
6. Install the ailerons and flaps on both wing halves
following the same procedure used to install the hinges in the rudder and elevator.
1. Install a 36" [914mm] servo extension on the elevator
servo. Tie the end of the servo extension to the string and carefully pull the extension through the fuselage.Tape or heat­shrink the leads together.
2. Install the elevator servo in the fuselage using the
hardware supplied with the servo.

it crosses the servo arm. Make a 90° bend at the mark and attach the pushrod to the servo arm with a FasLink.Cut off the excess pushrod.
7. Follow the same procedure to install the rudder servo.
Make sure the control horn is installed over the hardwood bloc k.
8. Trim the covering from over the flap and aileron
servo openings.
9. Connect 36" [914mm] ser vo extensions to the aileron
and flap servos. Use tape or heat-shrink to secure the extension to the servo lead.Tie the strings in the wing to the servo extensions and pull the extensions through the wing and out of the wing root. Install the flap and aileron ser vos in the wing using the hardware supplied with the servos.
10. Install the aileron pushrod on the aileron and aileron
servo arm following the same procedure used to install the elevator pushrod and control horn.Make sure the control horn is installed over the hardwood block.
11. Install the flap pushrod on the flap servo arm following
the same procedure used to install the aileron pushrod. Note: If you will be using a Y-harness on both of the flap
servos, you will need to install the servo arms on the same side of both flap servos so that they move in the same direction (both flaps move down at the same time),
12. Once you have the aileron and flap servos installed,
remove the horns and install the servo covers using two #2 x 3/8" [9.5mm] sheet metal screws. Remember to remove the screws and use thin CA to harden the screw holes.If you will be flying the Seawind ARF from water, we recommend that you apply a bead of silicone sealant between the servo covers and the wing to help seal the covers.
1.Use denatured alcohol to clean the 5/32" x 1" [4 x 25.4mm]
metal anti-rotation pins.Then, use epoxy to glue the pins in both wing panels, in the aft hole of the root rib. Apply a thin film of epoxy on the rib to seal the wood.
FINISH THE WING
18
Page 19
2. Inser t and glue the wing tip suppor t in the tip rib of the
left wing.
3. Test fit the left fiberglass wing tip on the left wing panel.
The wing tip curves downward. Use a felt-tip pen to mark the outline of the wing tip on the wing.
4.Remove the wing tip and use a sharp hobby knif e to trim
the covering from inside the wing tip outline.
5. Use epoxy to glue the wing tip to the wing. Make sure
that the tips are well sealed to the wing to prevent any water from getting in.You may want to apply clear tape or silicone sealant around the edges of the wing tips to seal them.
1.Insert the aluminum wing joiner in the fuselage. Space it
evenly on both sides of the fuselage.
2. Route the ser vo wires and air line tubing, if retracts are
installed, through the holes in the fuselage.
3. Secure the wing panels to the fuselage with two black
finger bolts. If you will be flying off of water, we recommend that clear tape be used to seal the joint between the wing panels and fuselage.
FINISH THE RADIO INSTALLATION
19
Page 20
4. Install the receiver on/off switch on the left side of the
radio tray.Wrap the receiver and receiver battery in foam and place them on the radio tray. If flying from the water, we recommend placing the receiver and battery in a plastic bag.
5. At this point you should have a lot of wires loose in the
fuselage.If you are like most modelers, you probably hav e a fe w #64 rubber bands that are not fuel soaked.Using these rubber bands, we are going to show you how to make harnesses to hold the servo wires, receiver antenna and air lines. This will protect them from any water that might get inside the fuselage.
6. Cut a piece of rubber band 3/4" to 1" [19 to 25.4mm]
long.Position the rubber band where needed.If you have long servo wires you may need several harnesses.The harnesses can easily be glued to the side of the fuselage with CA. For best adhesion, roughen the area with sandpaper before applying CA.
1. Glue the rubber bushing in the end of the aluminum
bailing tube, opposite the end for the machine screw. Insert the ball in the aluminum bailing tube and thread the 3-56 x 3/8" [9.5mm] machine screw into the aluminum bailing tube.
2. Use epoxy to glue the aluminum bailing tube in the hole
in the bottom of the fuselage.The rubber bushing goes to the inside of the fuselage. The aluminum bailing tube should be flush with the outside of the fuselage.Do not get epoxy in the tube.The ball must be able to move freely.The ball will float in the water and seal against the rubber bushing. In flight, the ball will roll back and allow water to escape from the fuselage.
3. Round one end of the 5/32" x 1-3/16" [4 x 30mm] wood
dowel rod.Glue the dowel in the aft end of the cabin top.The end of the dowel should be flush with the edge of the cabin.
FINISH THE FUSELAGE
20
Page 21
4. Remove the backing from the foam tape and apply it to
the cabin area of the fuselage.
5. Position the cabin on the fuselage by first inserting the
wood dowel in the hole at the top of the cabin opening.With the cabin top in position, drill a 1/16" [1.6mm] pilot hole in the front center of the cabin top and into the fuselage.Enlarge the hole in the cabin top to 3/32" [2.4mm].Secure the cabin top to the fuselage with a #2 x 3/8" [9.5mm] sheet metal screw and #2 flat washer.
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 carburetor
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 cer tain the control surfaces have remained centered.Adjust if necessary.
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 a rate in­between the high and low rates.
Note: The throws are measured at the widest part of the elevators, rudder and ailerons.
Note: If you will be flying the Seawind ARF off of water using the water rudder, once y ou hav e the rudder throws set, cut the excess water rudder control rod when the rudder is at its maximum throw.
IMPORTANT: The Seawind ARF has been extensively flown and tested to arrive at the throws at which it flies best. Flying your model at these throws will provide you with the greatest chance for successful first flights. If, after you have become accustomed to the way the Seawind ARF flies, you would like to change the throws to suit your taste, that is fine. However, too much control throw could make the model difficult to control, so remember, “more is not always better.”
These are the recommended control surface throws:
High Rate Low Rate
ELEVATOR: 5/8" [16mm] up 7/16" [11mm] up
5/8" [16mm] down 7/16" [11mm] down
RUDDER: 2" [51mm] right 1-1/8" [29mm] right
2" [51mm] left 1-1/8" [29mm] left
AILERONS: 1/2" [13mm] up 3/8" [10mm] up

At this stage the model should be in ready-to-fly condition with all of the systems in place including the engine, landing gear and the radio system.
1. Very Important: 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 1-1/32" [26mm] back from the leading edge of the wing.
2. With the wing attached to the fuselage, all par ts of the
model installed (ready to fly) and an empty fuel tank, place the model right-side up on a Great Planes CG Machine, or lift it right-side up at the balance point you marked.
3. If the tail drops, the model is “tail heavy” and the batter y
pack and/or receiver must be shifted f orw ard or w eight 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 Great Planes (GPMQ4485) “stick-on” lead. Begin by placing incrementally increasing amounts of weight in the nose of the fuselage until the model balances. Once you have 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, fuel and
water may soften the adhesive and cause the weight to fall off. Use 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.
1. With the wing level, have an assistant help you lift the
model by the nose of the fuselage and the bottom of the fuse under the TE of the rudder. 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 wing tip. An airplane that has been
laterally balanced will track better in loops and other maneuvers.
No matter if you fly at an AMA sanctioned R/C club site or if you fly 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 flying sites and AMA sanctioned flying events .Fill out the identification tag on page 26 and place it on or inside your model.
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 flying, 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-char ger 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 flying with batteries that are only partially charged.
Charge the Batteries
Identify Y our Model
PREFLIGHT
Balance the Model Laterally
IMPORTANT: The stated C.G. is where your model must
be balanced. The Seawind ARF does not have a C.G. range like most R/C planes. Do not move the C.G. forward or aft. Doing so will cause the plane to become difficult to control. This C.G. point has been extensively tested and you should not deviate from it.
More than any other factor, the C.G. (balance point) can have the greatest effect on how a model flies, and may determine whether or not your first flight will be successful.If you value this model and wish to enjoy it for many flights, DO NOT OVERLOOK THIS IMPORTANT PROCEDURE. A model that is not properly balanced will be unstable and possibly unflyable.
Balance the Model (C.G.)

Carefully balance your propeller and spare propellers before you fly. An unbalanced prop can be the single most significant 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.
We use a Top Flite Precision Magnetic Prop Balancer
(TOPQ5700) in the workshop and keep a Great Planes Fingertip Prop Balancer (GPMQ5000) in our flight box.
If the engine is new, follow the engine manufacturer’s instructions to break-in the engine. After break-in,
confirm that the engine idles reliably, transitions smoothly and rapidly to full power and maintains full power–indefinitely. 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.
Ground check the operational range of your radio before the first flight 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 b y your model and, while y ou 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 fly! Find and correct the problem first. 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.
Keep all engine fuel in a safe place, away from high heat, sparks or flames, as fuel is very flammable. 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, scarfs, 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 fingers to flip 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 fire.
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, fingers 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.

1) I will not fly my model aircraft in sanctioned events, air shows, or model flying demonstrations until it has been proven to be airworthy by having been previously, successfully flight tested.
2) I will not fly my model aircraft higher than approximately 400 feet within 3 miles of an airport without notifying the air port operator. I will give right-of-way to and avoid flying in the proximity of full-scale aircraft.Where necessary, an observer shall be utilized to supervise flying to avoid having models fly in the proximity of full-scale aircraft.
3) Where established, I will abide by the safety rules for the flying site I use, and I will not willfully and deliberately fly my models in a careless, reckless and/or dangerous manner.
5) I will not fly my model unless it is identified with my name and address or AMA number, on or in the model.Note: This does not apply to models while being flown indoors.
7) I will not operate models with pyrotechnics (any device that explodes, burns, or propels a projectile of any kind).
1) I will have completed a successful radio equipment ground check before the first flight of a new or repaired model.
2) I will not fly my model aircraft in the presence of spectators until I become a qualified flier, unless assisted by an experienced helper.
3) At all flying sites a straight or curved line(s) must be established in front of which all flying takes place with the other side for spectators. Only personnel involved with flying the aircraft are allowed at or in the front of the flight line. Intentional flying behind the flight line is prohibited.
4) I will operate my model using only radio control frequencies currently allowed by the Federal Communications Commission.
5) I will not knowingly operate my model within three
miles of any pre-existing flying 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 flight;nor should any part of the model
other than the landing gear, intentionally touch the ground, except while landing.
1. Fuelproof all areas exposed to fuel or exhaust residue
such as the cowl ring, cowl mounting blocks, wing saddle area, etc. If you will be flying off of water check all the joints where water may enter and seal them with clear tape or silicone sealant.
2. Check the C.G. according to the measurements
provided in the manual.
3. Be certain the battery and receiver are securely
mounted in the fuse. Simply stuffing them into place with foam rubber is not sufficient.
4. 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.
5. Balance your model
laterally
as explained in
the instructions.
6. Use thread-locking 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.
7. Add a drop of oil to the axles so the wheels will
turn freely.
8. Make sure all hinges are securely glued in place.9. Reinforce holes for wood screws with thin CA where
appropriate (servo mounting screws, cowl mounting screws, etc.).
10. Confirm that all controls operate in the correct direction
and the throws are set up according to the manual.
11. Make sure there are silicone clevis retainers on all the
clevises and that all servo arms are secured to the servos with the screws included with your radio.
12. 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.
13. Make sure any servo extension cords you may have
used do not interfere with other systems (servo arms, pushrods, etc.).
14. Secure the pressure tap (if used) to the muffler with
high temp RTV silicone, thread-locking compound or J.B.Weld.
15. Make sure the fuel lines are connected and are
not kinked.
16. Balance your propeller (and spare propellers).17. Tighten the propeller nut and spinner.
During the last few moments of preparation your mind may be elsewhere anticipating the excitement of the first flight. Because of this, you may be more likely to overlook certain checks and procedures that should be performed before the model is flown.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.

18. Place your name, address, AMA number and
telephone number on or inside your model.
19. Cycle your receiver battery pack (if necessary) and
make sure it is fully charged.
20. If you wish to photograph your model, do so before
your first flight.
21. Range check your radio when you get to the
flying field.
The Seawind ARF is a great-flying model that flies smoothly and predictably. The Seawind ARF does not, however, possess the self-recovery characteristics of a primary R/C trainer and should be flown only by experienced R/C pilots.
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.
The Seawind ARF takes off from the ground similar to any other tricycle landing gear airplane. It is recommended that no flaps be used during take off until the pilot becomes familiar with how the plane handles with flaps.
Before the model is ready for takeoff, it must first be set up to roll straight down the runway.With the engine running at a low idle, place the plane on the runway and, if your flying field permits, stand behind the model. Advance the throttle just enough to allow the model to roll. If the model does not roll straight down the runway, shut the engine off and adjust the nose gear pushrod as necessary. Do not use the rudder trim to correct the nose wheel because this will also affect the rudder. Note: Crosswinds may affect the direction the model rolls, so this test should be done in calm conditions, or with the model facing directly into the wind.
If possible, takeoff directly into the wind. If you are an experienced pilot, taking off in a crosswind is permissible (and sometimes necessary–depending upon the prevailing wind conditions and runway heading).Taking off into the wind will help the model roll straight and also reduces ground speed for takeoff.Taxi the model onto the runway or have an assistant carry it out and set it down, pointing down the runway into the wind. When ready, gradually advance the throttle while simultaneously using the left stick (rudder/nose wheel) to steer the model.Gain as much speed as the runwa y and flying site will practically allow before gently applying up elevator, lifting the model into the air. Be ready to make immediate corrections with the ailerons to keep the wings level, and be smooth on the elevator stic k, allowing the model to estab lish a gentle climb to a safe altitude before making the first turn (away from yourself). Do not “yank” back the elevator stick, forcing the plane into too steep of a climb which could cause the model to quit flying and stall.
Do a few taxi runs on the water before attempting to take off. Get used to how the model handles in water. As you use the water rudder to turn, you will notice that the Seawind ARF has a tendency to dip a wing tip float.This is normal as the CG of the airplane causes the airplane to shift balance on the main hull. It is possible that at low speeds part of the wing might also dip slightly under water.This is the reason all the wing tips and servo bays need to be sealed.
As you get ready to take off, align the airplane into the wind and then add throttle slowly. Concentrate on keeping the wings level using the ailerons while controlling heading with the rudder.The model should get up on the step within 50 feet. Let the plane pick up speed and gently pull up on the elev ator to take off.The take off run length will vary depending on the engine used.If the water is perfectly calm, add about 1/2 flaps
Taking Off from the Water
Taking Off from the Ground
CAUTION (THIS APPLIES TO ALL R/C AIRPLANES): If,
while flying, you notice an alarming or unusual sound such as a low-pitched “buzz,” this may indicate control surface
flutter
. Flutter occurs when a control surface (such as an aileron or elevator) or a flying surface (such as a wing or stab) rapidly vibrates up and down (thus causing the noise). In extreme cases, if not detected immediately, flutter can actually cause the control surface to detach or the flying surface to fail, thus causing loss of control followed by an impending crash.The best thing to do when flutter is detected is to slow the model immediately by reducing power, then land as soon as safely possible. Identify which surface fluttered (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 fluttered once, under similar circumstances it will probably flutter again unless the problem is fixed. Some things which can cause flutter are; Excessive hinge gap; Not mounting control horns solidly; Poor fit 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 flutter; Flying an over-powered model at excessive speeds.

to increase the wing lift and help the airplane get on the step quicker. This will not be necessary when taking off from choppy water.
For reassurance and to keep an eye on other traffic, it is a good idea to have an assistant on the flight 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 fly more smoothly at reduced speeds.
Take it easy with the Seawind ARF for the first few flights, gradually getting acquainted with it as you gain confidence. Adjust the trims to maintain straight and level flight. After flying around for a while, and while still at a saf e altitude with plenty of fuel, practice slow flight 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 fly around, executing various maneuvers and making mental notes (or having your assistant write them down) of what trim changes may be required to fine tune the model so it flies the way you like. Mind your fuel level, but use this first flight to become familiar with your model before 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.Slowly apply the flaps.Continue to lose altitude, but maintain airspeed by keeping the nose down as you turn onto the crosswind leg.Make your final 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 flare and the model is a foot or so off the deck, smoothly increase up elevator until it gently touches down.
One final note about flying your model. Have a goal or flight plan in mind for every flight. 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 finding 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 mak e certain you are
on the desired rates (high/low rates). A flight 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 fly in a safe manner.
GOOD LUCK AND GREAT FLYING!
