Center of Gravity (CG)
The CG location is measured from the leading edge of the wing at the root.
This CG location has been determined with the recommended Li-Po battery
(EFLB28004S30) installed in the middle of the battery compartment.
Tip: You can fl y your aircraft inverted to confi rm the CG is correct. The
aircraft should fl y level when fl ying inverted at ¾ throttle with little or
no elevator down pressure. If the aircraft CG is too far forward (nose-
heavy), signifi cant down elevator is required to fl y level. If the aircraft CG is too
far aft (tail-heavy), up elevator is required to fl y level.
Control Direction Test
Move the controls on the transmitter to make sure the aircraft control surfaces
move correctly and in the proper direction or reverse a servo.
After performing the Control Test, correctly set the failsafe. Make sure the
transmitter controls are at neutral and the throttle and throttle trim are in the
low position, then rebind the airplanes to your transmitter. If the receiver loses
its connection to the transmitter, the failsafe will drive the servos to the settings
made at binding.
IMPORTANT: In your transmitter, ensure the Channel 5 servo is in NORMAL
position for proper AS3X functionality.
