INTRODUCTION
In the late 1930’s the Grumman engineers were looking at
ways to improve the performance of the F4F Wildcat. They
realized the Wildcat could not be developed any farther
and a new, larger plane would need to be designed. The
F6F Hellcat was born. It had a larger engine, higher speed,
greater rate of climb, increased range and more repower. We
had many requests for a F6F Hellcat so Top Flite developed
the Giant F6F Hellcat ARF to get you in the air quickly with
a great looking model, without the sanding and covering
required to build a kit.
For the latest technical updates or manual corrections to the
Giant F6F Hellcat ARF visit the Top Flite web site at www.
top- ite.com. Open the “Airplanes” link, then select the
Giant F6F Hellcat 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.

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

SCALE COMPETITION
The Top Flite Giant Hellcat is a scale model and is therefore
eligible to compete in the Fun Scale class in AMA competition.
We receive many favorable reports of Top Flite ARFs in scale
competition! In Fun Scale, the “builder of the model” rule does
not apply. To receive the ve 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 pro le
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.
SAFETY PRECAUTIONS
PROTECT YOUR MODEL, YOURSELF & OTHERS…
FOLLOW THESE IMPORTANT SAFETY PRECAUTIONS
1. Your Giant F6F Hellcat 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 Giant F6F Hellcat 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 un yable model. In a few cases
the instructions may differ slightly from the photos. In those
instances the written instructions should be considered
as correct.
3. You must take time to build straight, true and strong.
4. You must use an R/C radio system that is in good condition,
a correctly sized engine, and other components as speci ed
in this instruction manual. All components must be correctly
installed so that the model operates correctly on the ground
and in the air. You must check the operation of the model
and all components before every ight.
5. If you are not an experienced pilot or have not own
this type of model before, we recommend that you get
the assistance of an experienced pilot in your R/C club for
your rst 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.
6. This model has been ight-tested to exceed normal use.
However, the Hellcat should be own in a scale-like manner.
High speed straight down dives should be avoided. It was
not designed to be used for extremely high stress ying,
such as racing, or if an engine larger than one in the
recommended range is used.
WARNING: The cowl and landing gear covers included
in this kit are made of berglass, the bers of which
may cause eye, skin and respiratory tract irritation. Never
blow into a part to remove 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 berglass parts. Vacuum the parts and the work
area thoroughly after working with berglass parts.
WARNING: Drilling, sawing, sanding, or machining
wood products can expose you to wood dust, a
substance known to the State of California to cause cancer.
Avoid inhaling wood dust or use a dust mask or other
safeguards for personal protection. For more information
go to www.P65Warnings.ca.gov/wood
ENGINE SAFETY PRECAUTIONS
Failure to follow these safety precautions may result
in severe injury to yourself and others.
Keep all engine fuel in a safe place, away from high heat,
sparks or ames, as fuel is very ammable. Do not smoke
near the engine or fuel; and remember that engine exhaust
gives off a great deal of deadly carbon monoxide. Therefore
do not run the engine in a closed room or garage.
Get help from an experienced pilot when learning to operate
engines.
Use safety glasses when starting or running engines.
Use a “chicken stick” or electric starter to start the engine.
If you do ip the propeller with your ngers, wear a heavy
leather glove, such as a welder’s glove. When hand starting
gas engines, if the engine should back re, the large prop
can cause severe injury to your hand and ngers.
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.
Stop the engine before making any engine adjustments.
The engine and muf er get hot! Do not touch them during
or right after operation. Make sure fuel lines are in good
condition so fuel will not leak onto a hot engine, causing a re.
To stop a gasoline powered engine an on/off switch must be
connected to the engine ignition. Do not throw anything into
the propeller of a running engine.
ELECTRIC MOTOR
SAFETY PRECAUTIONS
WARNING A spinning propeller has the potential to
cause serious and permanent injury to yourself and
others.
WARNING Once the motor batteries are connected
the electric motor can start at any time. Make sure the
fail safe is set on your radio to prevent the motor from
starting if the transmitter signal is lost.
WARNING: Stand clear of the propeller when handling
the aircraft. Make sure the aircraft is held securely until
the battery has been disconnected.
3
ALWAYS
ALWAYS remove the propeller if the motor batteries
will be connected when working on your plane.
ALWAYS remove the motor batteries from the plane
when charging.
ALWAYS switch on the transmitter first, then the
receiver.
ALWAYS unplug the motor batteries first before
switching off the receiver then transmitter.
NEVER
NEVER touch the motor during or right after operation.
The motor gets HOT!
NEVER switch off the transmitter with the motor
batteries plugged in.
NEVER reach through the arc of the propeller when
plugging the battery into the ESC.
LITHIUM BATTERY WARNING!
This product recommends the use of a lithium
polymer (LiPo) battery. Improper handling of
a LiPo battery could result in FIRE! A lithium
battery fire has the potential to ignite surrounding areas
and may cause property damage or cause personal
injury.
For safe LiPo handling, follow ALL of these
guidelines:
MOST IMPORTANT! Never leave the battery or
charger unattended during charging or discharging.
WARNING: Read the entire instruction sheet included
with your motor batteries. Failure to follow the
instructions could cause permanent damage to the
battery and its surroundings and cause bodily harm!
ALWAYS
ALWAYS follow the charging instructions included with
your charger for charging LiPo batteries. LiPo batteries
can cause serious damage or fire if misused.
ALWAYS use a LiPo-approved charger.
ALWAYS set the charger’s output volts to match the
battery volts.
ALWAYS charge a LiPo battery in a fireproof location
away from combustible materials.
ALWAYS balance charge the battery.
ALWAYS store and transport LiPo batteries in a fireproof
container away from combustible materials.
ALWAYS KEEP OUT OF THE REACH OF CHILDREN.
ALWAYS keep LiPo batteries out of the reach of animals.
A punctured battery may cause a fire.
ALWAYS disconnect the battery and unplug the charger
after the charge is complete.
ALWAYS keep a supply of sand accessible when
charging a LiPo battery. Dumping sand on the battery
will assist in extinguishing a LiPo chemical fire.
ALWAYS remove the batteries from the plane after a
crash. Set them aside in a safe location for at least 20
minutes. If the batteries are damaged in the crash, they
could catch fire. If the battery starts to swell, quickly
move the battery to a safe location, preferably outside
away from combustible material. Place it in a bucket,
covering the battery with sand.
NEVER
NEVER use water to try and put out a LiPo fire.
NEVER charge or use a battery that is deformed, bent,
crushed or has any type of visible damage.
NEVER use a NiCd/NiMH peak charger to charge a
LiPo battery.
NEVER charge in excess of 4.20V per cell unless the
battery is rated for a higher voltage.
NEVER charge at currents greater than 1C unless the
battery is rated for a higher charge rate.
NEVER trickle-charge a LiPo battery.
NEVER allow the battery temperature to exceed 140
degrees F (60 degrees C).
NEVER disassemble or modify the pack wiring in any
way or puncture the cells, as this may result in a fire.
NEVER discharge below 2.7V per cell. It is recommended
to not discharge below 3.7V per cell.
NEVER charge the battery or set the charger on
combustible materials.
NEVER charge the battery inside a vehicle or in a
location that could be damaged in the event of a LiPo
fire.
NEVER put a LiPo battery in the pocket of any clothing.
NEVER charge the batteries in the plane. Disconnect the
batteries and remove them from the plane immediately
after landing.
NEVER allow the battery to short circuit by touching
exposed wires together. This may cause a fire.
NEVER operate or store batteries below 40˚F or above
110 ˚F (4 -4 3˚C )
We, as the manufacturer, provide you with a top quality,
thoroughly tested ARF and instructions, but ultimately the
quality and yability of your nished model depends on
how you build it; therefore, we cannot in any way guarantee
the performance of your completed model, and no representations are expressed or implied as to the performance
or safety of your completed model.
REMEMBER: Take your time and follow the instructions
to end up with a well-built model that is straight and true.

DECISIONS YOU MUST MAKE
This is a partial list of items required to nish the Giant F6F
Hellcat ARF that may require planning or decision-making
before starting to build. Order numbers are provided in
parentheses.
Gas Engine Recommendations
The recommended engine size range for the Giant F6F
Hellcat ARF is a 55 – 61cc [3.4 – 3.7 ci.] two-stroke gasoline
engine. We used the DLE-55, DLE-61 and O.S. GT60 engines.
Other engines can also be used but you may need to make
modi cations for mounting those engines.
❍ DLE-55 (DLEG0455)
❍ DLE-61 (DLEG0061)
❍ O.S. GT60 (OSMG1560)
The stock muf ers for DLE engines can be used.

Radio Equipment
The radio installation for the Giant F6F Hellcat ARF can be
achieved using four different radio set-ups: a Basic Radio
Set-up, an Advanced Radio Set-up and the S.Bus System
Set-up using S.Bus servos or non S.Bus servos. All control
surfaces require the use of a high-quality, metal geared servo
of at least 95 oz-in of torque. A servo of 40 oz-in of torque can
be used for the throttle and choke. We have included in the
back of this manual 4 diagrams showing the different set-ups,
what is required for each set-up and where the components
are used. Once you have decided on which radio set-up you
are going to use, remove the diagram and follow it as you
install the radio system. This instruction manual will show
the installation of the non S.Bus set-up.
The following list shows the common components required
for all set-ups.

Basic Radio Set-up
The Basic Radio Set-up connects the two aileron servos,
two ap servos, two elevator servos and the rudder and tail
wheel steering servos with Y-harnesses. This method will
require a 7-channel receiver.
Note: See the included layout drawing for required servos,
servo extensions and Y-harnesses.
Advanced Radio Set-up
The Advanced Set-up has each servo plugged into the receiver
on its own channel. The channels can then be mixed together
using the transmitter. This method will require an 11-channel
receiver for the controls. A 13-channel receiver is required
for the optional drop tank and if the lights will be controlled
through the receiver.
Note: See the included layout drawing for required servos
and servo extensions.
S.Bus System
A Cutting-Edge Alternative to Standard Servo
Installation!
The innovative Futaba S.Bus system lets you unleash your
ight system’s full potential and cut down on cable clutter
at the same time. It uses digital serial data communication
technology to transmit control signals between your receiver
and servos. A single S.Bus cable can carry signals to as
many channels as your transmitter can handle. You no longer
have to worry about plugging in the wrong servo to the
wrong channel, because each servo knows what channel it
is dedicated to in advance.

analog and digital servos, too. By providing today’s pilots
with tomorrow’s technology, the Futaba S.Bus system is
nothing short of revolutionary.
Installing the S.Bus System
Installation is actually simpli ed as compared to your normal
system installation. Using the S.Bus system you plug a battery
into the SBC-1 channel changing tool, using it to program
which channel you want the servo to operate on.
Once programmed, the
servo will operate as
required, regardless of
which lead it is plug ged into.
Do this for all of the servos
that you want to operate on
the S.Bus system. Install
the servos in the airplane
and plug them into the S.Bus lead, piggybacking them one
onto another. Once completed, you plug one lead into the
receiver for all of the servos and all of the servos will function
as programmed. One lead operates up to 16 servos!
S.Bus leads are available in a number of different lengths to
accommodate installation into any size airplane, regardless
of its complexity.
There are many choices for the
S. Bus receivers; some are tiny
3-port receivers with others
being up to 18 channels. The 8
PWM outputs can be used as
you would normally set up a
model, allowing you to split the
model and have some of it set up as S.Bus while other servos
are not using the S. Bus system. Something else to note is
that some of the S. Bus servos and receivers are HV, or High
Voltage, meaning that you could run a straight 2S LiPo for
your receiver battery.
Many servo choices are
available for use in a wide variety
of aircraft from micros to the
largest models.
Your system is not limited to programming only through the
SBC-1 channel changing tool and your transmitter. Utilizing the
USB interface, the CIU-2, you can do all of the programming
using your PC. Programming with this interface gives more
exibility and programming options than can be achieved
with any other radio system. To utilize standard, non-S.Bus
servos, you simply use the S.Bus decoder instead of the
S.Bus lead.
S.Bus System Set-up (using standard servos)
This set-up allows the use of non S.Bus servos. The retract
servo (or controller for electric retracts), optional drop tank
and optional receiver controlled lights are plugged directly
into the receiver.
NOTE: See the included layout drawing for required servos,
servo extension, S.Bus hubs and S.Bus Decoders. This
set-up will also require a SBC-1 S.Bus Channel Setting Tool
(FUTM4190) or CIU-3 USB Interface (FUTM0953) to program
the S.Bus decoders.

1. If necessary, use a covering iron with a covering sock
❏
to go over the wing, ap and aileron to remove any wrinkles.
The best method to remove the wrinkles is to glide the iron
over the covering until the wrinkles disappear, then go over
the area again, pushing down on the iron to bond the covering
to the wood. If the wrinkles don’t disappear, the balsa in that
area might be exing inward. If this is happening, don’t press
down. Simply let the heat of the iron shrink the covering. If the
wrinkles momentarily disappear, then immediately reappear,
the iron may be too hot, thus causing air bubbles. Lower the
temperature of the iron or use a sharp #11 blade or T-pin
to puncture several holes in the covering, then reheat. The
suggested iron temperature is around 360 degrees F.
The Grumman F6F Hellcat went from test models to
combat in less than 18 months. Grumman built a total of
12,275 F6F Hellcats. It rst saw combat in August 1943 in
an attack on Marcus Island. The F6F Hellcat was credited
with destroying 5,223 aircraft. It had a kill-to-loss ratio
of 19:1 with the U.S. Navy/Marine Corps. The F6F Hellcat
was considered one of the best ghters of WWII.
Install the Wing Tip Light
1. The red LED will be installed in the left outer wing panel.
❏
Using a 4.8 volt receiver battery and receiver, plug each LED
into the receiver. Plug the receiver battery into the receiver.
Use a piece of masking tape to identify the LED color.
9
2. Tie the end of the string from the wing tip light recess
❏
to the plug of the red LED. Secure the string with a piece of
masking tape.
3. Pull the wire through the wing until the connector exits
❏
the root of the wing panel.
4. Insert the LED in one of the plywood LED supports.
❏
Position the support in the light recess so that it matches
the shape of the wing leading edge.
7. Glue the LED support in the wing tip.
❏
8. Last chance to test the red LED to make sure it is
❏
working and is the correct color. Position the wing tip lens
over the LED and mark the outline of the lens on the wing.
5. Attach the white wing tip light decal on the front of the
❏
LED support and the adjacent side of the wing tip light recess.
The LED support can also be painted white.
6. Glue the red LED in the hole in the plywood LED support.
❏
9. Use a T-pin to poke holes in the covering inside the
❏
lens outline.
10. Wipe off the outline and glue the lens to the wing tip
❏
with canopy glue.
11. Go back to step 1 and install the green LED in the
❏
right outer wing panel.
10
Install the Flap Servo
1. Carefully remove the left ap servo hatch from the
❏ ❏
wing by peeling off the masking tape holding the hatch to
the wing. Use a paper towel dampened with lighter uid
(CAUTION: Very Flammable) or similar solvent to remove
any glue left behind from the tape.
2. Install the rubber grommets and metal eyelets in
❏ ❏
the ap servo.
5. Once the epoxy has
❏ ❏
cured, remove the clamps.
Place a 1/16" [1.6mm] spacer,
such as a piece of cardstock
or a piece of paper folded
several times, under the servo
and between each mounting
block to raise the servo off the
servo hatch. After the servo is installed the spacer will be
removed, providing adequate spacing for vibration isolation.
6. Drill 1/16" [1.5 mm] holes through the blocks for the
❏ ❏
servo mounting screws. Mount the servo to the blocks with
the screws that came with the servo. Remove the servo
mounting screws and apply a couple of drops of thin CA in
each hole to harden the threads. Allow the CA to fully harden.
Then, reinstall the screws and remove the spacer.
3. Center the servo arm spline of the ap servo in the
❏ ❏
opening of the servo hatch cover. Position the two 7/8" x 5/8"
x 3/8" [20 x 15 x 8mm] hardwood blocks as shown and mark
the locations on the hatch cover.
To increase the strength of the glue joint, use a T-pin to
prick holes into the gluing surface of the servo blocks and
the plywood servo hatch. Be careful to not prick holes
completely through the servo hatch and covering.
7. Make two marks on the top of the servo hatch,
❏ ❏
centered on the two ap servo mounting blocks.
8. Drill 1/16" [1.5 mm ] holes through the servo hatch
❏ ❏
and into the servo blocks at the two previously made marks.
Install two #2 x 3/8" (9.5mm) self-tapping at head screws to
secure the servo mounting blocks to the aileron servo hatch.
Use thin CA to harden the screw threads.
4. Use 6-minute epoxy to glue the two blocks to the
❏ ❏
bottom of the servo hatch over the servo block locations.
Thoroughly coat the end of the blocks and allow them to set
for a few seconds to allow the blocks to absorb the epoxy.
Then, recoat the blocks. Use clamps to hold the blocks to
the servo hatch.
9. Following your radio setup diagram, connect the
❏ ❏
appropriate servo extension to your ap servo. Cut a piece
11
of the supplied heat shrink tubing in half and slide it over
the servo connections. Shrink the tubing by applying heat
to the tubing.
10. If installing the S.Bus setup, connect the S.Bus
❏ ❏
decoder or S.Bus hub to the ap servo extension. Secure
the connection with a piece of heat shrink tubing if installing
the S.Bus decoder.
NOTE: If installing the Non S.Bus setup, follow the instructions
included with the SBC-1 S.Bus Channel Setting Tool
(FUTM4190) or CIU-3 USB Interface (FUTM0953) to program
the decoder. We set ap number 1 to channel 7.
13. Place the ap servo hatch with the servo in the wing.
❏ ❏
Be certain that the hatch is positioned correctly as shown.
Secure the hatch using four #2 x 3/8" [9.5mm] at head sheet
metal screws. Use thin CA to harden the screw threads.
Install the Aileron Servo
11. Plug the ap servo and receiver battery into the
❏ ❏
receiver. Switch on the transmitter and center the servo
trims. Temporarily install a servo arm on the ap servo, 60
degrees from the centerline of the servo. Test the movement
for the correct direction.
12. Use the string in the wing to pull the ap wires
❏ ❏
through to the aileron servo hatch location.
1. Install the aileron servo on the aileron servo hatch
❏ ❏
following the same method used to install the ap servo.
2. Following your radio setup diagram, connect the
❏ ❏
appropriate servo extension to your aileron servo. Or, plug
the aileron servo into the S.Bus decoder or hub. Secure the
connectors with a piece of heat shrink tubing.
Note: We set aileron number 1 to channel 5 in the S.Bus setup.
3. Use the string in the wing to pull the ap and aileron
❏ ❏
extensions or S.Bus decoder or hub through the wing.
12
4. Secure the aileron hatch to the wing using four #2
❏ ❏
x 3/8" [9.5mm] at head sheet metal screws. Use thin CA to
harden the screw threads.
1. Slide a silicone clevis retainer over a 4-40 threaded
❏ ❏
metal clevis. Thread a 4-40 nut followed by the 4-40 metal
clevis, threaded 16 turns onto a 4-40 x 6" [152mm] metal
pushrod. Attach the clevis to the aileron servo arm 5/8"
[16mm] from the center of the arm.
5. Go back to step 1 on page 11 and install the right
❏ ❏
ap and aileron servos following the same procedure. The
left and right wing ap servos face the same direction.
NOTE: If installing S.Bus, we put the right wing ap #2 on
channel 8 and right aileron #2 on channel 6.
Install the Aileron and Flap Pushrods
Do the left aileron rst. Temporarily plug the aileron servo
into the receiver. Switch on the transmitter and plug a receiver
battery into the receiver. Center the aileron trim and adjust the
aileron servo arm so that it is perpendicular to the centerline
of the servo.
2. Position the control horn so that it is in line with the
❏ ❏
pushrod and over the plywood mounting plate. The holes
in the control horn should be aligned with the hinge line of
the aileron. On the aileron, mark the four mounting holes.
Remove the control horn and drill a 5/64" [2mm] pilot hole at
each mark. Do not drill completely through the aileron. Attach
the control horn using four #4 x ½" sheet metal screws. Use
thin CA to harden the holes.
13
3. Install the metal solder clevis in the 2nd hole from
❏ ❏
the outer end of the control horn. Center the aileron servo
and aileron. Mark the pushrod where it meets the solder
clevis. Remove the pushrod and the solder clevis and cut
the pushrod 1/4" [6.5mm] past the mark. Solder the solder
clevis to the pushrod using the techniques described in the
following Hot Tip.
Hot Tip
HOW TO SOLDER
1. Use denatured alcohol or other solvent to thoroughly
clean the pushrod. Roughen the end of the pushrod with
coarse sandpaper where it is to be soldered.
2. Apply a few drops of soldering ux to the end of the
pushrod. Then, use a soldering iron or a torch to heat it.
“Tin” the heated area with silver solder by applying the
solder to the end. The heat of the pushrod should melt the
solder – not the ame of the torch or soldering iron – thus
allowing the solder to ow. The end of the wire should be
coated with solder all the way around.
3. Place the clevis on the end of the pushrod. Add another drop of ux. Then, heat and add solder. The same
as before, the heat of the parts being soldered should
melt the solder, thus allowing it to ow. Allow the joint to
cool naturally without disturbing. Avoid excess blobs, but
make certain the joint is thoroughly soldered. The solder
should be shiny, not rough. If necessary, reheat the joint
and allow to cool.
4. Immediately after the solder has solidi ed, but while it
is still hot, use a cloth to quickly wipe off the ux before
it hardens. Important: After the joint cools, coat the joint
with oil to prevent rust. Note: Do not use the acid ux that
comes with silver solder for electrical soldering.
4. Slide a silicone clevis retainer over the solder clevis.
❏
Reinstall the aileron pushrod with the threaded clevis attached
to the control horn. Adjust the threaded clevis so that the
aileron is centered. Apply a drop of thread locker to the
threads of the pushrod behind the clevis. Tighten the 4-40
nut against the clevis.
5. Assemble and connect the ap pushrods following
❏
the same procedure. We installed the pushrod in the outer
hole of the control horn and the hole 5/8" [16mm] from the
center of the servo arm.
6. Return to step 1 and install the aileron and ap pushrods
❏
on the right wing.
The F6F Hellcat was tted with the 2,100 hp Pratt &
Whitney R-2800-10W engine, the same engine used in
the Corsair and the P-47 Thunderbolt. It had a gross
weight of 15,413 lbs. Its maximum speed was 376 mph
at 23,400 ft. It carried six 50-caliber machine guns with
400 rounds of ammunition.
This is what a properly soldered clevis looks like – shiny
solder with good ow, no blobs and ux removed.

Mount the Retracts
Install the left retract rst.
3. Tie the Actuator extension or pressure lines along with
❏
a ap and aileron servo extension or S.Bus hub, depending
on your setup, and a 16" (400 mm) servo extension for the
wing tip lights to the string in the retract bay. Pull the lines
out the hole in the top of the wing and tape them to the top
of the wing.
1. Trim the a xle that is included with the Robart retracts to
❏
2" [51mm] long. File a at spot at the end of the axle. Insert
the axle through the included 5" [127mm] wheel. Slide the
6mm thick aluminum wheel spacer onto the axle. Insert the
axle into the retract. Apply a drop of threadlocker to the 1032 x 3/16" [4.8mm] set screw, included with the retract, and
tighten the set screw onto the at of the axle. Make sure that
the wheel rotates freely.
2. Connect a 12" (305mm) Actuator Extension (included
❏
with the retracts) to the retract. If installing pneumatic retracts,
attach the air lines to the retract.
4. Secure the retract in the wing with six 8-32 x 1" (25mm)
❏
machine screws and #8 lock washers. Before installing, apply
a drop of thread locker to the threads on the machine screws.
5. Operate the retract to make sure the wheel does not
❏
bind in the wheel well.
6. Position the retract cover over the retract and drill 1/16"
❏
(1.5mm) pilot holes using the holes in the cover as a guide.
Mount the cover to the wing with #2 x 3/8" (9.5mm) at head
screws. Harden the screw holes with thin CA.
15
8. Install the second landing gear door mount and position
❏
as shown.
9. Retract the landing gear and position the landing gear
❏
door over the strut. Center the door in the opening. Place a
piece of masking tape on each side of the retract. Mark the
position of the mounting holes on the tape.
7. Extend the landing gear and snap one of the landing
❏
gear door mounts over the retract. Rotate the mount and
slide it up the strut past the pin.
10. Use the 1/16" (1.5mm) plywood spacers to adjust
❏
the height of the gear doors to match the bottom of the
wing. If one of the gear door mounts is too high, use 80 grit
sandpaper to sand the face of the mount. Once satis ed
with the height of the gear doors, glue the plywood spacers
to the gear door mounts.
16
11. Center the gear door mounts and the mounting holes
❏
on the gear doors with the marks on the wing. Using one of
the mounting holes as a guide, mark the hole location on the
gear door mount. Remove the gear door. Drill a 1/16" (1.5mm)
pilot hole at the mark on the gear door mount.
12. Temporarily mount the gear door to the gear door
❏
mount with a #2 x ½" (12.5mm) sheet metal screw. Drill the
three remaining pilot holes using the holes in the gear door
as a guide.
apply a couple of drops of thin CA between the gear door
mount and the landing gear strut.
15. Go back to step 1 on page 15 of Mount the Retracts
❏
and install the right retract.
Join the Wing Panels
Note: Keep the retracts in the retracted (up) position.
1. Use 6-minute epoxy to glue the two 3/8 x 2-3/8" [10 x
❏
60mm] diameter forward wing dowels in the leading edge of
the wing. The wing dowels should protrude approximately
5/8" [16mm] from the wing.
