Center of Gravity

An important part of preparing the aircraft for flight is

properly balancing the model.

Caution: Do not inadvertently skip this step!

The recommended Center of Gravity (CG) location

for your model is 3 1/2 to 4-inches (89 to 102mm)

behind the leading edge of the wing where it meets

the fuselage. Mark the location for the Center of

Gravity on the top of the wing next to the fuselage

as shown. Adjust components as necessary so the

model hangs level. This is the correct balance

point for your model. You might find that you need to

shift the battery slightly to either the front or back of

the fuselage to achieve the correct balance.

The model should be suspended inverted to check

the CG. If retracts are installed, place them in the

extended position during the balancing process.

Preflight

Check Your Radio

Before going to the field, be sure that your batteries

are fully charged per the instructions included with

your radio. Charge both the transmitter and receiver

pack for your airplane. Use the recommended

charger supplied with your particular radio system,

following the instructions provided with the radio. In

most cases, the radio should be charged the night

before going flying.

Before each flying session, be sure to range

check your radio. See your radio manual for the

recommended range and instructions for your radio

system. Each radio manufacturer specifies different

procedures for radio systems. Next, start the motor.

With the model securely anchored, check the range

again. The range test should not be significantly

affected. If it is, don’t attempt to fly! Have your radio

equipment checked out by the manufacturer.

Note: Keep loose items that can get entangled

in the propeller away from the prop. These

include loose clothing, or other objects such as

pencils and screwdrivers. Especially keep your

hands away from the propeller.

Double-check that all controls (aileron, elevator,

rudder, flaps and throttle) move in the correct

direction. Check the radio installation and make sure

all the control surfaces are moving correctly (i.e.,

the correct direction and with the recommended

throws). Test run the motor and make sure it

transitions smoothly from off to full throttle and

back. Also ensure the motor is installed according

to the manufacturer’s instructions, and operating

consistently. Check all the control horns, servo horns

and clevises to make sure they are secure and in

good condition. Repair or replace any items that

would be considered questionable. Failure of any of

these components in flight would mean the loss of

your aircraft.
