Installing the Flight Battery and Arming the ESC
Arming the ESC also occurs after binding as
previously described, but subsequent connection
of a fl ight battery requires the following steps.
AS3X
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.
It is normal for linear servos to make noise. Noise
is not an indication of a faulty servo.
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.
