Part Needed

Right and left wing panels

Tools and Adhesives Needed

Instant thin CA glue
CA remover/debonder
Paper towels
T-pins (one for each hinge)

Caution: The control surfaces, including the ailerons,
elevators, and rudder come with the hinges installed,
but the hinges are not glued in place. The hinge is
constructed of a special material that allows the thin
CA to “wick” (penetrate) and distribute throughout the
hinge, securely bonding them to the wood structure.
It is imperative that you properly secure the hinges in
place per these instructions using high-quality thin
CA glue.

Step 1. Carefully remove the aileron from one of the wing
panels, noting the position of the hinges. The P-51 comes with
high-quality CA-type hinges.

Step 2. Remove each hinge from the wing panel and place a
T-pin in the center of each hinge as shown. Slide each hinge into
the wing panel until the T-pin is snug against the trailing edge of
the wing panel.

Step 3. Slide the aileron onto the wing until there is only a
slight gap between the wing panel and aileron. The hinge is now
centered in the wing panel and the aileron. You can now remove
the T-pins and snug the aileron up against the wing panel.

Step 3 photo

Step 4. Deflect the aileron and completely saturate the hinge

with thin CA glue. Be sure not to deflect the aileron too far; the
top of the aileron should just touch the top of the wing trailing
edge. When the hinge is glued in place, there should be no more
than a 1/32" gap maintained throughout the length of the aileron.

Section 1

Hinging the Ailerons

CONTINUED

Step 5. Turn the wing panel over, deflect the aileron in the
opposite direction, and apply thin CA to the other side of the
hinges as in the previous step. Make sure the thin CA penetrates
completely into both the aileron and wing panel.

Step 6. Using CA remover/debonder and a paper towel,
remove any excess CA glue that has accumulated on the wing or
aileron surface.

Step 7. Repeat Steps 1-6 for the opposite wing and aileron.

Step 8. Allowing time for both ailerons to completely dry,

firmly grasp the wing and aileron and applying medium pressure
check that they are securely attached and cannot be pulled apart.
Use caution when gripping the wing and aileron as not to crush
the structure.

Step 9. Work the aileron up and down several times to “work
in” the hinges and check for proper movement.

Section 1

Hinging the Ailerons

CONTINUED

Parts Needed

Right wing panel assembly
Left wing panel assembly
Wing joiner

Tools and Adhesives Needed

Ruler
Masking tape
30-minute epoxy
Rubbing alcohol
Paper towels

Step 1. Locate the wing joiner. Using a ruler and felt-tipped
pen or pencil, measure and mark the exact center of the joiner
as shown.

Step 2. Trial fit the wing joiner into one of the wing panels.
It should insert smoothly up to the line marked in Step 1.
Now slide the other wing panel onto the joiner until the two
panels meet. If the fit is too tight, it may be necessary to lightly
sand the wing joiner.

Step 2 photo

Step 3. Check for correct dihedral angle. Place the wing on a

large flat surface with one wing panel resting flat on the surface
the opposite wing panel should be 5

1

/4" from the flat surface
(see illustration below). If necessary, sand the wing joiner until
the proper dihedral is achieved. There should be no gap at the
wing center joint. Once you are satisfied with the fit, separate the
wing panels and remove the wing joiner.

Note: Read through the remaining steps of this section
before proceeding to epoxy the wing panels together.

Hint: It is extremely important to use plenty of epoxy
when joining the wing panels together. It will also be
helpful to use wax paper under the wing center joint to
avoid gluing the wing to your worktop.

Section 2

Joining the Wing Halves

CONTINUED

Step 4. Mix approximately 1 ounce of 30-minute epoxy. Using
an epoxy brush, apply a generous amount of epoxy to the wing
joiner cavity of one wing panel.

Step 5. Completely coat one half of the wing joiner with epoxy
up to the centerline made in Step 1. Insert the epoxy-coated
side of the joiner into the wing joiner cavity up to the mark on
the joiner.

Step 6. Apply a generous amount of epoxy to the other wing
panel joiner cavity.

Step 7. Apply epoxy to the exposed portion of the wing joiner
and to both wing roots.

Step 7 photo

Step 8. Carefully slide both wing panels together. Firmly press

both halves together, allowing the epoxy to run out. Use alcohol
and paper towels wipe off the excess epoxy. Check to make sure
there are no visible gaps between the two wing panels.

Step 9. Use masking tape to securely hold both wing halves
together. Place the wing assembly back onto the flat work surface
(covered with wax paper), and check the dihedral again as in
Step 3.

Step 10. Double-check the wing center joint for any gaps and
allow the epoxy to cure overnight.

Section 2

Joining the Wing Halves

CONTINUED

Parts Needed

Wing assembly
Aileron servos w/mounting hardware (2)
Servo hatch screws (#2 x 3/8") (8)
18" servo wire extension (JRPA099) (2)
Large Servo Arm (JRPA212) (1 pkg.)

Tools and Adhesives Needed

Phillips screwdriver
Thin CA
Thick CA

Step 1. Locate the aileron hatch on the underside of the wing
panel. Using a sharp hobby knife carefully cut along the edges
of the hatch, then remove the hatch from the wing panel. Also
cut out the slot for the servo arm at this time. Locate the servo
lead extension exit holes on the top of the inboard portion of the
wing. Using a sharp hobby knife carefully cut away the covering
over the hole.

Note: The aileron servo will be mounted to the hatch.

Step 2. Install the recommended servo hardware (grommets

and eyelets) supplied with your radio system onto the aileron
servo. Temporarily install a long half servo arm (JRPA212) onto
the servo and test fit the servo to the hatch. The servo output
shaft and control arm should be centered in the slot of the hatch.
Once satisfied, mark the location for the servo mounting blocks.

Step 2 photos

Step 3. Locate the servo mounting blocks. Using a few drops

of thin CA, tack glue them in place on the marks made in the
previous step. Check the fit of the servo between the mounting
blocks. When satisfied with the fit, permanently glue the
mounting blocks in place by first wicking thin CA between the
mounting blocks and the hatch, and then using thick CA create
a fillet around the base. Let the CA completely dry before
proceeding to the next step.

10

Section 3

Installing the Aileron Servos

CONTINUED

Step 4. Place the aileron servo between the mounting blocks
and using a felt-tipped pen mark the location of the four servo
mounting screws. Note that the servo must not touch the hatch
in order to isolate engine vibration.

Step 5.

Note: Before mounting the servo, we suggest that

you electronically center the aileron servos and install
the servo arm to avoid having to remove the servo to
mount the servo arm in subsequent steps.

Remove the servo and using a 1/16" drill bit, drill the four servo
mount screw holes marked in the previous step. Using the
screws supplied with your radio system, mount the servo to the
mounting blocks.

Step 6. Locate the aileron servo lead extension (18") (JRPA099)
and connect it to the aileron servo lead. Secure the connectors
by tying them in a knot or use a commercial connector that pre­vents the servo lead connections from becoming disconnected.

Hint: It is always a good idea to secure the servo
connectors and servo extension together to prevent
the wires from becoming unplugged inside the wing.

Step 6 photo

Step 7. Locate the preinstalled string in the servo hatch opening

and tie it to the servo lead extension connector. Locate the other
end of the string in the exit hole you uncovered in Step 1 and
carefully fish the servo lead and extension through the wing.

Note: Tape the servo extension connector to the
topside of the wing to prevent the connector from
slipping back into the wing structure.

Section 3

Installing the Aileron Servos

CONTINUED

Step 8. Place the servo hatch assembly back into the opening
and check the fit. Once satisfied with the fit, measure in from
each corner 1/4" and using a 1/16" drill bit, drill the four mount­ing screw holes through the hatch and plywood tab underneath.

Step 9. Locate four #2 x 3/8" wood screws and using a Phillips
screwdriver secure the hatch to the wing.

Step 11. Repeat Steps 1 through 10 for the opposite
aileron servo.

Section 4

Installing the Aileron Control Horns & Linkages

CONTINUED

Step 5. Using a small Phillips screwdriver, attach the control
horn using the provided hardware.

Step 6. Locate the aileron control wire (6" threaded on one end)
and thread on a clevis a minimum of 12 turns. Attach the clevis
to the middle hole in the control horn. To hold the aileron at the
neutral position, place a piece of masking tape on the aileron to
secure it to the wing trailing edge. With the aileron at neutral and
aileron servo electronically centered mark the wire where it
crosses the aileron servo arm.

Step 7. Remove the clevis and wire from the control horn
and make a 90-degree bend at the mark made in the previous
step. Cut off the excess wire leaving 5/16" remaining after the
90-degree bend.

Step 8. Re-attach the clevis securing it to the horn using a
clevis keeper. Slide the other end of the wire through the aileron
servo arms outer most hole and secure it with a wire keeper

Section 5

Installing the Retract Servo

CONTINUED

Step 4. Trail fit the retract servo and mounting plate to the
retract servo rails temporarily installed in the wing assembly.
Position the servo output shaft as close to the center of the wing
as shown. Mark the location of the plate on the servo rails using
a felt-tipped pen or pencil. Remove the retract servo and plate
assembly and also remove the rails from the wing noting the
orientation of the rails in the wing.

Step 5. Remove the retract servo from the mounting plate.
Use thick CA and carefully glue the retract servo mounting
plate to the servo rails. Align the plate with the marks you made
on the rails. Allow the CA to fully dry before mounting to the
wing assembly.

Step 6. Mix approximately 1/2 ounce of 6-minute epoxy and
carefully glue in the retract servo mount assembly to the
wing assembly. Be sure to position the rails with the proper
orientation as noted in the previous step. Allow the epoxy to cure
completely before proceeding to the next step.

Step 6 photo

Step 7. Permanently mount the retract servo to the mounting

plate using the screws provided with your retract servo.

secure the wheel collar in place.

Step 2. Slide the main landing gear wheel onto the wire and
secure the wheel in place with another wheel collar.

Step 3. Repeat Steps 1 and 2 for the other main landing
gear wheel.

Step 4. With both main wheels installed on the landing gear
check to make sure there is no binding of the wheels in the
wheel wells. This is best checked by hooking up the retract servo
to your radio system and operating the servo via the transmitter.

Note: If there is binding, it may be necessary to slightly
bend the main landing gear wire to free up the wheel.
Two pairs of pliers works well for this, using one pair to
hold the base of the wire without putting any pressure
on the retract mechanism.

Step 5. Locate the landing gear fairing, two mounting straps,
mounting screws, and nuts. Note that there is a left and right
fairing. The outside of the fairing has white and black trim that
matches the strips on the bottom of the wing.

Medium fuel tubing (1/2")

Tools and Adhesives Needed

6-minute epoxy
Thin CA
Masking tape
Felt-tipped pen or pencil
Hobby knife
9/64" hex driver
Slip-joint pliers

Step 1. Locate the predrilled holes in the fuselage wing mount
plate and install the blind nuts into these holes. Use a pair of
slip-joint pliers and a scrap piece of plywood as shown to press
in the blind nuts. Once the blind nuts are securely pressed in,
use a few drops of thin CA to glue them into place. Be sure not
to get any CA in the treads of the blind nuts.

Step 2. Locate the predrilled holes in the wing trailing edge and
use a sharp hobby knife to remove the covering as shown.

Step 3. Locate the plywood wing mounting plate. Align the
plate with the trailing edge of the wing and the center joint as
shown and mark the outline of the plate with a felt-tipped
pen/pencil. Use a sharp hobby knife to trim away the covering
1/16" inside the lines you just drew.

20

Section 7

Mounting the Wing to the Fuselage

CONTINUED

Step 4. Mix 1/2 ounce of 6-minute epoxy and coat both the
wing and plywood plate. The groove cut into the plywood plate
should be facing up to allow the plate to conform to the dihedral
of the wing. Align the plate and clamp in place. Wipe away any
excess epoxy with rubbing alcohol and paper towels. Allow the
epoxy to fully cure.

Caution: Use scrap plywood under the clamps to
prevent damage to the balsa wing structure.

Step 5. Once the epoxy has fully cured, use a drill and
5/32" drill bit to drill through the plywood plate. Use the
predrilled holes in the wing as a guide.

Step 6. Mount the wing to the fuselage using the two provided
mounting bolts and washers. Tighten the bolts finger tight and
align the wing to the fuselage by measuring from the wing tips
to the center rear of the fuselage as shown. The measurements
should be equal on both sides. It may be necessary to enlarge
the holes in the mounting plate to get the proper alignment.

Step 7. Once the wing is properly aligned, locate the radiator
scoop and use a sharp hobby knife to cut away the covering over
the two wing bolt access holes. Trial fit the scoop to the wing,
aligning it with the fuselage as shown.

CONTINUED

Step 9 photo

Step 8. With the radiator scoop properly positioned, use a

pencil to trace the outline onto the wing. Use only enough
pressure to make a slight indentation in the covering. Use a
sharp hobby knife to cut away the covering 1/16" inside the line
you just made.

Step 9. Remove the wing and place a piece of wax paper or
plastic wrap on the wing saddle where the radiator scoop con­tacts the fuselage. Remount the wing. Mix at least 1/2 ounce of
6-minute epoxy and coat both the radiator scoop and the wing.
Align the radiator scoop with the fuselage and the bare wood
exposed in Step 9. Secure the scoop in place using masking
tape and wipe away any excess epoxy with rubbing alcohol and
paper towels.

Step 9 photos

Step 10. Once the epoxy has cured remove the wing and use a

1/4" piece of fuel tubing over the mounting bolts to keep them
from falling out.

Parts Needed

Fuselage assembly
Wing assembly
Horizontal stabilizer
Elevator joiner wire (U-shaped)
Vertical fin

Tools and Adhesives Needed

30-minute epoxy
Sharp hobby knife
Long ruler
Rubbing alcohol
Paper towels
Felt-tipped pen or pencil
T-pin

Step 1. The slots for the horizontal and vertical stabilizer are
located in the rear of the fuselage. Using a sharp hobby knife
carefully remove the covering over the slots.

Step 2. Locate the horizontal stabilizer and elevator assembly
and remove the elevators and hinges. Use a felt-tipped pen or
pencil and ruler to mark the center of the stabilizer at the trailing
edge as shown.

Step 3. Mark the center of the stabilizer saddle at the trailing
edge of the saddle. You can hold the ruler at the back portion of
the stab opening and use a pen or pencil to mark the center
location through the opening of the vertical fin as shown.

Note: The horizontal stabilizer is positioned all the
way forward in the saddle area to allow room for the
elevator joiner wire. The wire will be inserted through
the saddle area before the horizontal stabilizer is glued
in place.

Step 4. Slide the horizontal stabilizer through the saddle
opening and align the marks you made in the two previous
steps. Once you are satisfied with the alignment, carefully place
a T-pin through the stabilizer and the saddle at the trailing
edge. This will keep the horizontal stabilizer in place
during alignment.

Section 8

Installing the Tail Group
(Horizontal and Vertical Fin)

CONTINUED

Step 5. Mount the wing to the fuselage and measure the
distance from the wing tip to the tip of the horizontal stabilizers
as shown in the illustration below. Carefully adjust the horizontal
stabilizer until the measurement is equal on both sides making
sure to keep the marks on the stabilizer and saddle aligned.

Step 6. With the horizontal stabilizer properly aligned,
carefully mark the stabilizer with a felt-tipped pen or pencil
where it meets the fuselage. Mark both the top and bottom of
the horizontal stabilizer.

Step 7. Remove the stabilizer and use a sharp hobby knife to
carefully remove the covering from the center of the stabilizer,
cutting 1/16" inside the lines you marked in the previous step.
Use only enough pressure to cut the covering and not the wood
underneath, as doing so will severely weaken the structure of the
horizontal stabilizer.

Step 8. Re-install the stabilizer into the fuselage. Use the lines
drawn in Step 6 to reposition the stab correctly. Looking from
behind the plane, check to make sure the horizontal stabilizer is
parallel to the wing as shown in the illustration below. If any
adjustments are require lightly sand the stabilizer saddle to bring
the horizontal stabilizer into alignment with the wing.

Step 9. Locate the vertical fin and rudder assembly and
remove the rudder and hinges from the fin. Trial fit the fin into
the fuselage as shown, making sure to align the trailing edge of
the rudder with the fuselage. Use a felt-tipped pen or pencil to
mark both the fin and fuselage where they come together.

Step 10. Remove the fin and use a sharp hobby knife to remove
the covering where the fin inserts into the fuselage, cutting 1/16"
inside the lines you drew in the previous step. Also cut away
the covering on top of the fuselage 1/16" inside the lines you
drew. Use only enough pressure to cut the covering not the
wood underneath.

Step 11. Re-install the fin into the fuselage to check the fit.

Note: Read through the remaining steps of this

section before proceeding to Step 12 and have all
your supplies and parts laid out ready to install.

Step 12. Remove the horizontal stabilizer and vertical fin
from the fuselage. Mix 1 ounce of 30-minute epoxy and coat
the horizontal stabilizer saddle and then coat both sides of the
stabilizer center section.

Step 13. Slide the elevator joiner wire through the saddle area
before inserting the stabilizer. Insert the stabilizer into the fuse­lage and align with the wing. Wipe of the excess epoxy using
rubbing alcohol and paper towels.

Hint: Coat the center of the elevator joiner wire
with petroleum jelly to keep the epoxy from setting
up on the wire.

Step 14. Use the remaining epoxy coat the bottom of the
vertical fin and the slot in the fuselage for the fin. Try to keep the
epoxy away from the joiner wire. Insert the fin into the fuselage
and make sure it is fully seated in the slot. Wipe away any
excess epoxy with rubbing alcohol and paper towels.

Step 15. Double-check the alignment of the horizontal stabilizer
and vertical fin and use masking tape to secure it in place. Use
rubbing alcohol and paper towels to clean the epoxy off of the
elevator joiner wire. Allow the epoxy to fully cure.

Left and right elevator halves
Hinges (6)

Tools and Adhesives Needed

Thin CA
CA remover/debonder
6-minute epoxy
Drill
Drill Bit: 3/32"
T-pins
Rubbing alcohol
Paper towels

Note: The elevator halves are joined together with
the U-shaped wire supplied with the kit. This wire
will be used to drive both elevator halves and is
epoxied into place.

Caution: The hinges included with the P-51 are
made of a special material that allows the thin CA
to “wick” (penetrate) and distribute throughout the
hinge, securely bonding them to the wood structure.
It is imperative that you properly secure the hinges
in place using high quality thin CA glue.

Step 1. Locate the left and right elevator halves and temporarily
install the elevators to the horizontal stabilizer. Center the
elevator joiner wire in the tail of the fuselage and use a felt­tipped pen or pencil to mark the outline of the wire onto
the elevators.

Step 2. Remove the elevators. Using a 3/32" drill bit, carefully
drill the holes into the elevators using the marks you made in the
previous step as a guide. Drill directly down the center of the
elevator and only as far as needed.

Hint: Use a piece of masking tape on the drill bit
as a depth gauge.

Step 3. Temporarily install the elevators back onto the
horizontal stabilizer and check for fit. The elevator halves
should be equal to each other and move freely up and down.
If the elevators are not equal, you can remove them and
carefully bend the joiner wire until they come into alignment.
Once satisfied with the fit, remove the elevator halves.

Hinging the Elevators

CONTINUED

Step 4. Place a T-pin in the center of each hinge and slide the
hinges into the horizontal stabilizer until the T-pin is snug
against the trailing edge as shown.

Note: In the following steps you will permanently
install the elevators. Do not glue the hinges in place
until the joiner wire epoxy has cured.

Step 5. Mix at least 1/4 ounce of 6-minute epoxy. Using a
toothpick as an applicator, coat the inside of the joiner wire holes
and the wire where it inserts into the elevators.

Step 6. Install each elevator onto the hinges and the joiner
wire. Remove the T-pins and push the elevators close to the
stabilizer until there is only a slight gap (1/32" or less) at the
hinge line. Wipe away any excess epoxy with rubbing alcohol
and paper towels. Use masking tape to hold the elevators in
place and allow the epoxy to cure completely before moving to
the next step.

Step 7. Once the epoxy has cured, deflect the elevators
down and use a high-quality thin CA to completely saturate
each hinge.

Step 8. Turn the fuselage over and repeat the hinge gluing
process by deflecting the elevators in the opposite direction and
again completely saturating each hinge with thin CA. Wipe away
any excess CA using CA Remover/Debonder and a paper towel.
Allow the CA to completely dry.

Step 9. Once the CA has dried, check the hinges for security by
trying to pull the elevators from the stabilizer. Use only slight
pressure and be sure not to crush the wood structure of the
stabilizer or elevator.

Step 1. Locate the tail wheel assembly and use pliers to make a
90-degree bend 1" up from the bushing as shown. Measure over
1" from the bend and trim off the excess wire. This portion of the
wire will be inserted into the rudder.

Step 2. Temporarily install the rudder using the hinges
provided; do not glue the hinges at this time. Hold the tail wheel
assembly up to the fuselage as shown and mark the location
where the wire will insert into the rudder. Remove the rudder.

Step 3. Using a 3/32" drill bit, drill the rudder following
the marks you made in the previous step. Make sure to drill
straight into the rudder.

Hint: Use a piece of masking tape on the drill
bit as a depth gauge to avoid drilling too deep.

Step 4. Use a sharp hobby knife to make a notch in the bottom
portion of the rudder to accept the tail wheel wire and allow
the rudder to seat properly against the vertical fin. Tests fit the
rudder and tail wheel assembly to the vertical fin and make
adjustments until there is only a slight gap (1/32" or less) at
the hinge line.

the fuselage and drill the screw mounting holes using a 1/16"
drill bit. Using the two provided screws, mount the bracket to the
fuselage as shown.

Step 6. Install the rudder hinges placing a T-pin through the
center of each hinge to keep it centered while installing
the rudder.

Step 7. Mix at least 1/4 ounce of 6-minute epoxy and use a
tooth pick to coat the inside of the hole you drilled in the rudder.
Also coat the wire that inserts into the rudder. Use caution not to
get epoxy into the tail wheel assembly bushing.

Step 8. Install the rudder and wipe away excess epoxy using
rubbing alcohol and paper towels. Remove the T-pins and move
the rudder against fin until there is only a slight gap (1/32" or
less). Use masking tape to secure the rudder to the fin and allow
the epoxy to cure.

Step 9. Once the epoxy has cured, deflect the rudder fully in
one direction and saturate each hinge with thin CA. Deflect the
rudder in the opposite direction and saturate each hinge again
with thin CA. Allow the CA to dry. Use CA remover/debonder to
wipe off any excess CA on the rudder hinge line.

Step 10. Once the CA has completely dried, check the rudder
for security by trying to pull the rudder from the fuselage. Use
only enough pressure to test for security and be careful not to
damage the wood structure of the rudder or fin.

Important: When installing the control horns,
the holes in the control horns where the
pushrod attaches must be directly in line
with the control surface hinge line.

Step 1. To locate the elevator control horn position, measure
over 3/4" on the bottom left side of the horizontal stabilizer along
the fuselage. Mark the elevator as shown with a felt-tipped pen
or pencil. This mark will be the center of the elevator control
horn location.

Step 2. Place the center of the control horn on the elevator at
the mark made in the previous step. Mark the hole positions of
the control horn with a felt-tipped pen or pencil.

Step 3. Remove the control horn and drill 1/16" holes through
the elevator as marked. Make sure to drill these holes parallel to
each other to allow the back plate of the horn to fit properly.

Step 4. Using the provided screws and backplate, attach the
elevator control horn and fasten in place with a Phillips screwdriver.

Step 5. Measure 11/2" up from the bottom of the rudder on the
left side of the rudder. Mark the location with a felt-tipped pen
or pencil. This mark will serve as the center for the rudder
control horn.

Parts Needed

Metal tubes (1 short, 1 long)
Clunk (fuel pickup)
Fuel pickup tubing
Fuel tank
Metal caps (2)
Rubber stopper
3mm screw

Tools and Adhesives Needed

Hobby knife
Screwdriver (medium)

Step 1. Locate the tank parts.

Note: The stopper provided with the P-51 has three

holes hat are not bored completely through the stopper.
You will only be using two holes: one for the fuel
pickup and one for the fuel vent. Make sure not to
open the third hole, as this will cause a fuel leak.

Step 2. Locate the rubber stopper. Insert the shorter brass fuel
tube into one of the holes in the stopper so that an equal amount
of tube extends from each side of the stopper. This tube will be
the fuel tank pickup that provides fuel to the engine.

Step 3. Slide the smaller of the two caps over the tube on the
smaller end of the rubber stopper. The small end will be inserted
into the fuel tank. The larger cap is placed on the other side of
the rubber stopper that makes the cap. Loosely install the 3mm
screw through the stopper.

Step 4. Locate the other brass fuel tube and bend it carefully
using your fingers. This will be the fuel tank vent tube.

Step 5. Slide the vent tube into one of the two remaining holes
in the stopper from the tank (small cap) side.

34

Section 12

Assembling the Fuel Tank

CONTINUED

Step 6. Locate the short piece of silicone fuel tubing and the
fuel tank clunk. Install the clunk onto one end of the silicone
tubing and the other end onto the fuel tank pickup tube (straight
tube) in the stopper.

Step 7. Carefully insert the assembly into the fuel tank. Note the
position of the vent tube; it must be at the top portion of the fuel
tank to function properly. Also, it may be necessary to shorten
the length of the fuel pickup tubing to make sure the clunk does
not rub against the back of the fuel tank. You should be able to
turn the tank upside down, which allows the clunk to freely drop
to the top of the tank.

Step 8. Tighten the 3mm screw carefully—do not over tighten.
This allows the rubber stopper to form a seal by being slightly
compressed, thus sealing the fuel tank opening.

Important: Be sure to differentiate between the vent
and the fuel pick-up tube. Once the tank is mounted
inside the fuselage, it will be difficult to tell the tubes apart.

Note: The fuel tank will be installed in the next section.

Step 1. Using a pair of canopy scissors, cut out and trim the
cockpit and exhaust detail.

Step 2. Using the detail drawings, glue the cockpit detail to the
fuselage using Shoe Goo or similar type adhesive. Secure the
parts with tape until the glue has dried.

Step 3. Using the drawings, locate the position of the scale
exhaust. It will be necessary to cut the exhaust pieces and glue
one part to the fuselage and the other to the cowl. If necessary,
cut an access hole for the cowl mounting screw before gluing on
the exhaust.

Step 4. Locate the decal sheet and cut out the decals for the
P-51 using a sharp hobby knife and scissors.

Step 5. Use the drawings to locate the position of the decals on
the P-51. Use a water spray bottle with 2-3 drops of dish soap
added to the water and spray both the fuselage and sticky side of
the decal. This will allow you to reposition the decal if necessary.
Once satisfied with the position use a paper towel to squeegee
out the water. Allow the decal to dry over night.

Note: There may be some clouding under the decal,
but this will go away as the decal dries.

The following control throws offer a good place to start with your
first flights. We recommend only one rate setting for the P-51.
As you become more familiar with the handling of your model,
you may wish to add a second rate setting.

Recommended Control Throws

Aileron 9/16" up 1/2" down
Elevator 1 1/16" up 1 1/16" down
Rudder 1 1/4" right and left

Recommended CG Location

An important part of preparing the aircraft for flight is properly
balancing the model. This is especially important when various
engines are mounted.

Caution: Do not inadvertently skip this step!!

The recommended Center of Gravity (C.G.) location for the
P-51 60 is 4 3/4" behind the leading edge of the wing.

If necessary, move the battery pack or add weight to either the
nose or the tail until the correct balance is achieved. Stick-on
weights are available at your local hobby shop and work well for
this purpose.

Preflight at the Field

Range Test Your Radio

Step 1. Before each flying session, range check your radio.

This is accomplished by turning on your transmitter with the
antenna collapsed. Turn on the radio in your airplane. With your
airplane on the ground, you should be able to walk 30 paces
away from your airplane and still have complete control of all
functions. If not, don't attempt to fly! Have your radio equipment
checked out by the manufacturer.

Step 2. Double-check that all controls (aileron, elevator,
throttle, rudder) move in the correct direction.

Step 3. Before you fly, be sure that your batteries are fully
charged per the instructions included with your radio.

Adjusting Your Engine

Step 1. Completely read the instructions included with your

engine and follow the recommended break-in procedure.
Step 2. At the field, adjust the engine to a slightly rich setting

at full throttle and adjust the idle and low speed needle so that a
consistent idle is achieved.

Step 3. Before you fly be sure that your engine idles reliably,
transitions, and runs at all throttle settings. Only when this is
achieved should any plane be considered ready for flight.
