Safety in Flying
This is NOT a toy! It is a very high-performance RC airplane capable of high speeds and extreme maneuvers. It
should only be operated by a competent pilot in a safe area with proper supervision.
ONLY fly your aircraft in a safe, open area, away from spectators and vehicles–and where it is legal to fly.
NEVER fly over an unsafe area, such as a road or street.
Never fly too close to yourself or spectators.
Never run your motor inside a house or building with the propeller attached – Remove the prop for safety.
Required Items
CA Glue – Thin and Thick
Epoxy glue
Hobby Knife
Small Phillips Screwdriver
Set Metric Allen Wrenches
Scissors
Small Pliers
Wire Cutters
Masking tape
Optional – Heat gun
Before Starting Assembly
Examination
Unpack your airplane and examine the components. Check for damage of any kind. If you see any damage,
please contact Value Hobby immediately.
Covering
Your airplane was packed in plastic at the factory without any wrinkles in the covering. You may notice some
wrinkles now; more likely, you will notice a few in a day or two or the first time you take the plane out to the
flying field. These wrinkles are the result of wood shrinkage and/or expansion. Balsa wood changes size and
shape slightly as it is exposed to varying humidity in the air. This is a natural property of balsa wood. As your
airplane adjusts to the weather in your part of the world, wrinkles may appear and disappear. Wrinkles may be
removed with the gentle application of heat to the covering material on your airplane. The best tool to use is a
hobby heat gun. Apply the heat gently: the covering material will shrink as you apply the heat, and this will
remove the wrinkles. BE CAREFUL! Too much heat applied too quickly can damage the covering, either by
causing it to pull away from the wood at seams and corners or even by melting it. The covering will shrink at low
temperature with patient application of heat.
Wrinkles in the covering DO NOT affect flight performance.
Remove the canopy before attempting to use heat on your covering! The canopy is made of thermo-activated
plastic and WILL deform with the application of heat. Do not apply heat to the canopy.
If you need to clean your airplane, we recommend using a damp towel. The paint used on the canopy and cowl is
not safe for all cleaners. In particular, DO NOT use alcohol on these parts, it will remove the paint

firewall using four M4*25mm (1.0in) socket head
screws and four M4 washer.
Step2. Position the engine on the mount, adjust
the engine so that the distance between the
firewall and drive washer is 135mm (5.3in).
www.valuehobby.com/p-51d-mustang-arf.html
17
Step3. Mark the location for engine mounting
screws. Drill the holes on the mark and install the
engine on the mounting using the screws provided
with the engine.
Step4. Use a pencil to mark the location for throttle
pushrod wire on the firewall.
Step5. Drill a hole through the firewall for the
throttle pushrod wire.
Step6. Slide the throttle pushrod wire through the
firewall.
Step7. Install the throttle servo. Electronically
adjust the throttle arm and servo arm to make
them move rightly.
Step8. Connect the pushrod wire to the servo arm.
Step9. The fuel tank can be assembled as a two line
system consisting of a vent (pressure) line to the
muffler and a carburetor line. Filling and emptying of
the tank would need to be done through the
carburetor line, or an optional fuel fill valve. The tank
can also be assembled as a three line system having a
vent line, carburetor line, and fill line. If install a fill
line, puncture the top of the stopper above the
sealed off fuel tube hole. The fill and carburetor lines
should extend out 13mm beyond the stopper and the
vent line should be bent upwards and left uncut.
With the tubes installed in the stopper, the stopper
plates loosely in place with the PM3x25mm screw to
hold the assembly together.
www.valuehobby.com/p-51d-mustang-arf.html
18
Step10. Fit the stopper assembly into the tank with
the vent line pointing toward the top of the tank, but
not touching. The fuel tubing and clunks (fuel pickup)
on the carburetor and fill lines should almost reach
the back of the tank but not touch. The clunks must
be able to move freely inside the tank when
assembled. Adjust the length of the fuel tubing
accordingly. When satisfied, tighten the PM3x25mm
screw in the stopper to secure it in place (do not
over-tighten). Mark the side of the tank that must
face up when installed in the plane. We also suggest
marking the tubes in the stopper.
Step11. Use a M3*10mm(0.1in) socket head screw
to install the fuel tank tray to the fuselage.
Section8. Electrical Motor Installation

locknut and four washers to install the electrical
motor mount to the fuselage.
Step2. Install the motor to the motor box.
www.valuehobby.com/p-51d-mustang-arf.html
19
Section9. Final assembly

screws and two M3 washers to install the hatch to
the fuselage.
Step2. Use four M2*8mm (0.3in) self-tapping
screws to install the cowling to the fuselage.
Step3. Install the spinner and prop.
Step4. Use epoxy and wing joiner to attach the two
panels together.
Step5. Install the assembled wing to the fuselage.
