Important ESC and model information
Check the motor rotating direction
The motor should rotate clockwise when viewing the
plane from the rear.
The ESC included with the model has a safe start. If the motor battery is connected to the ESC and the throttle stick
is not in the low throttle or position, the motor will not start until the throttle stick is moved to the low throttle or off
position. Once the throttle stick is moved to the low throttle or off position, the motor will emit a series of beeps.
Several beeps with the same tune means the ESC has detected the cells of the battery. The count of the beeps
equals the cells of the battery. The motor is now armed and will start when the throttle is moved.
The motor and ESC come pre-connected and the motor rotation should be correct. If for any reason the motor is
rotating in the wrong direction, simply reverse two of the three motor wires to change the direction of rotation.
The motor has an optional brake setting. The ESC comes with brake switched off and we recommend that the model
be flown with the brake off. However, the brake could be accidentally switched on if the motor battery is connected to
the ESC while the throttle stick is set at full throttle. To switch the brake off, move the throttle stick to full throttle and
plug in the motor battery. The motor will beep one time. Move the throttle stick to low throttle or the off position. The
motor is ready to run and the brake will be switched off.
Battery Selection and Installation. We recommend the 11.1V 2200mAh 25C Li-Po battery. If using another battery,
the battery must be at least a 11.1V 2200mAh 25C battery. Your battery should be approximately the same capacity,
dimension and weight as the 11.1V 2200mAh 25C Li-Po battery to fit the fuselage without changing the center of
gravity significantly.

When balancing your model, adjust the
motor battery as necessary so the model
is level or slightly nose down. This is the
correct balance point for your model. After
the first flights, the CG position can be
adjusted for your personal preference.
1.
2.
The recommended Center of Gravity
(CG) location for your model is
(89-94mm) forward from the leading
edge of the main wing (as shown) with
the battery pack installed. Mark the
location of the CG on top of the wing.
When balancing your model, support
the plane at the marks made on the
bottom of the main wing with your
fingers or a commercially available
balancing stand. This is the correct
balance point for your model. Make
sure the model is assembled and
ready for flight before balancing.

Before getting started, bind your receiver
with your transmitter. Please refer to your
Transmitter Manual for proper operation
CAUTION: To prevent personal injury, DO
NOT install the propeller assembly onto
the motor shaft while testing the control
surfaces. DO NOT arm the ESC and do
not turn on the transmitter until the
Transmitter Manual instructs you to do so.
Tips: Make sure all control sticks on your
radio are in the neutral position (rudder,
elevator, ailerons) and the throttle in the
OFF position. Make sure both ailerons
move up and down (travel) the same
amount. This model tracks well when the
left and right ailerons travel the same
amount in response to the control stick.
1. Move the controls on the transmitter to
make sure aircraft control surface move
correctly. See diagrams below.
Assemble the spinner and propeller as shown.

The table shows the factory settings for the control
horns and servo arms. Fly the aircraft at the factory
settings before making changes.
After flying, you may choose to adjust the linkage
positions for the desired control response. See the table
shown
Pull the tube the clevis to the linkage
Carefully spread the clevis, then insert the clevis pin into
the desired hole in the control horn.
More the tube to hold the clevis on the control horn.

Find a suitable flying site
Perform the range check for your plane
Monitor your flight time
Find a flying site clear of buildings, trees, power lines and other obstructions. Until you know how much area will be
required and have mastered flying your plane in confined spaces, choose a site which is at least the size of two to three
football fields - a flying field specifically for R/C planes is best. Never fly near people - especially children who can wander
unpredictably.
As a precaution, an operational ground rage test should be performed before the first flight each time you go out.
Performing a rang test is a good way to detect problems that could cause loss of control such as low batteries, defective
or damaged radio components, or radio interference. This usually requires an assistant and should be done at the actual
flying site you will be using.
First turn on the transmitter, then install a fully - charged battery into the fuselage. Connect the battery and install the hatch.
Remember, use care not to bump the throttle stick. otherwise, the propeller/fan will turn and possibly cause damage or
injury.
Note: Please refer to your Transmitter Manual that came with your radio control system to perform a ground range check.
If the controls are not working correctly or if anything seems wrong, do not fly the model until you correct the problem. Make
certain all the servo wires are securely connected to the receiver and the transmitter batteries have a good connection.
Monitor and limit your flight time using a timer (such as on a wristwatch or in your transmitter if available). When the
batteries are getting low you will usually notice a performance drop before the ESC cuts off motor power, so when the
plane starts flying slower you should land. Often (but not always) power can be briefly restored after the motor cuts off by
holding the throttle stick all the way down for a few seconds.
To avoid an unexpected dead-stick landing on your first flight, set your timer to a conservative 4 minutes. When your alarm
sounds you should land right away.

Before flying the model

Take off
While applying power, slowly steer to keep the model straight. the model should accelerate quickly. As the model gains
flight speed you will want to climb at a steady and even rate. P-51 will climb out at a nice angle of attack (AOA).
Always choose a wide-open space for flying your plane. It is ideal for you to fly at a sanctioned flying field. If you are not
flying at an approved site always avoid flying near houses, trees, wires and buildings. You should also be careful to avoid
flying in areas, where there are many people, such as busy parks, schoolyards, or soccer field. Consult laws and
ordinances before choosing a location to fly your aircraft. After takeoff, gain some altitude. Climb to a aspects of flight
does not make sense, including high speed passes, inverted flight, loops, and point rolls.
Land the model when you hear the motor pulsing (LVC) or if you notice a reduction in power. If using a transmitter with a timer,
set the timer so you have enough flight time to make several landing approaches.
Recharge the battery and repair the model as needed .The model’s three point landing gear allows the model to land on
hard surfaces. Align model directly into the wind and fly down to the ground. Fly the airplane down to the ground using
1/4-1/3 throttle to keep enough energy for proper flare. Before the model touches done, always fully decrease the throttle
to avoid damaging the propeller or other components. The key to a great landing is to manage the power and elevator all
the way to the ground and set down lightly on the main landing gear. After a few flights you will find the model can be set
down lightly on the mains and you can hold the nose wheel off balancing the model on the mains until it slows and gently
settles the nose.
Repairs to the foam should be made with foam safe adhesives such as hot glue, foam safe CA, and 5min epoxy. When
parts are not repairable, see the Spare Parts List for ordering by item number.
Always check to make sure all screws on the aircraft are tightened. Pay special attention to make sure the spinner is
firmly in place before every flight.
