Flight Battery Installation and ESC Arming

Arming the ESC also occurs after binding as
previously described, but subsequent connection
of a fl ight battery requires the following steps.
It is normal for linear servos to make noise. Noise
is not an indication of a faulty servo.
The AS3X ® system will not activate until the
throttle stick or trim is increased for the fi rst
time. Once active, the control surfaces may
move rapidly and noisily on the aircraft. This is
normal. AS3X technology will remain active until
the battery is disconnected.
CAUTION: Always keep hands away
from the propeller. When armed, the motor will
turn the propeller in response to any throttle
movement.
CAUTION: Always disconnect the Li-Po
battery from the aircraft receiver when not
fl ying to avoid over-discharging the battery.
Batteries discharged to a voltage lower than
the lowest approved voltage may become
damaged, resulting in loss of performance and
potential fi re when batteries are charged.

Center of Gravity (CG)

The CG location is 31-37mm back from the leading
edge of the top wing.
This CG location has been determined with the
included 1S 150mAh 3.7V Li-Po battery installed
in the battery cavity located on the bottom of the
aircraft.
Balance the model on the edge of a metal ruler to
fi nd the Center of Gravity. Place the ruler on the
underside of the airframe at the CG location shown
in the image to the right. Move the battery forward
or aft until the model closely balances at this
location.
