These are general guidelines measured from our own

flight tests. You can experiment with higher rates to

match your preferred style of flying.

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

the F-16 is 2

-inch (55–65mm) back from

the leading edge of the wing. Mark the location for the

Center of Gravity on the bottom of the wing next to the

fuselage as shown.

When balancing your F-16, support the plane

rightside-up at the marks made on the bottom of the

wing with your fingers or a commercially available

balancing stand. Adjust components as necessary

so the model hangs level or slightly nose down. This

is the correct balance point for your model. You

might find with the different power and landing gear

configurations that you need to shift the battery slightly

in the compartment or add a small amount of weight

to either the front or back of the fuselage to achieve

the correct balance.

After the first flights, the CG position can be adjusted

for your personal preference.

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

out flying.

Note: Keep loose items that can get drawn into

the intake away from the intake. These items

include loose clothing, or other objects such as

pencils and screwdrivers.

Double-check that all controls (aileron, elevator, rudder

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 engine is

installed according to the manufacturer’s instructions,

and it will operate consistently.

Check all the control horns, servo horns, and

clevises to make sure they are secure and in good

condition. Replace any items that would be considered

questionable. Failure of any of these components in

flight would mean the loss of your aircraft.
