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.

INTRODUCTIONTABLE OF CONTENTS

2

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.

❏ 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.

❏ 9. Temporarily plug the throttle servo and receiver battery

into your receiver. Adjust the throttle pushrod so that the
throttle operates correctly. We normally set up our throttle so
that the engine can be stopped by moving a switch, causing
the throttle to close completely.
