Step 10
Control Test
Warning:
Keep everything clear of the propeller
before starting the control test in the event that you
accidentally turn on the motor.
Note:
If you are using a Spektrum or JR DSM
radio, you are going to have to reverse the
ailerons on the transmitter prior to flying. Failure
to do this will result in the ailerons being reversed
and will likely result in a crash.
1. Be certain that the throttle stick is in the “off”
(low throttle) position and that both trim levers
are centered.
2. Switch on the transmitter and check to make sure
the transmitter has power.
3. Install the flight battery into the fuselage and plug it
into the battery connector.
4. Move the stick from side to side. The ailerons on
the trailing edge of the wings should move per your
transmitter input. When the stick is pushed to the
right, the right aileron should deflect upward and
the left aileron downward, and vice versa.
5. Pull the stick back and the elevator control surface
should move upward (as shown).
6. Move the stick full forward. When this is done, the
elevator control surface should move down (as
shown).
7. When the test is complete, be sure to disconnect
the flight battery first, and then turn off the
transmitter. This should be done each time you
turn off the airplane.
Note:
It is very important to make sure that the
control surfaces are at 0 degrees when the
transmitter control stick and trim levers are centered.
(See Steps 5 and 8 for making needed adjustments to
control surfaces.)
If your airplane is not responding correctly to the
transmitter input, do not fly! Some correction is needed.

Step 9
Motor Test
Warning:
Keep everything clear of the propeller be-
fore starting the motor test so you do not damage any
property or harm anyone.
1. Make sure the throttle is in the “off” (low throttle)
position.
2. Turn on the transmitter.
3. Plug the flight battery into the lead inside the
fuselage.
4. Secure the battery inside the fuselage cavity by
looping the hook and loop straps around the
battery.
5. Your P-51D Mustang has a built-in throttle
arming feature that must sense the throttle stick in
the “off” (low throttle) position before it will spin the
propeller. Advance the throttle forward and the
propeller should spin at a high speed. The throttle
stick needs to be in the “off” (low throttle) position
each time the battery is plugged into the airplane.
6. When finished with the motor test, be sure to
disconnect the battery first, and then turn off the
transmitter. Follow this step each time you need
to turn the airplane off. Additionally, each time you
use your airplane you should always place the
throttle in the “off” (low throttle) position, and then
turn on the transmitter and plug the battery pack
into the lead from the fuselage.
7. Make any trim adjustments, as necessary, prior to
flight (see Making Trim Adjustments to the
Horizontal Stabilizer and Making Adjustments to
the Ailerons).
