ESC/Receiver Arming, Battery Installation and Center of Gravity

CAUTION: Always keep hands away from the
propeller. When armed, the motor will turn the
propeller in response to any throttle movement.
Arming the ESC/receiver occurs after binding, but
subsequent connection of a fl ight battery requires
the following steps.
AS3X
®
The AS3X system will not activate until the
throttle stick 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.
1. Apply hook and loop tape to the battery.
2. Attach the battery to the hook and loop strip on
the fuselage.
Center of Gravity (CG)
Measure foreward 94mm from the trailing edge of
the wing, where the wing meets the fuselage and
place a mark. Balance the airplane on this CG mark.
3. Lower the throttle and throttle trim to the
lowest settings on your transmitter. Power
on your transmitter, then wait 5 seconds.
4. Connect the battery to the ESC, noting proper
polarity. Keep the plane immobile and
away from wind for 5 seconds to allow the
AS3X system to initialize. A series of tones
and a continuous LED indicates a successful
connection.
CAUTION: Always disconnect the Li-Po
battery from the ESC when not fl ying to eliminate
power supplied to the motor. The ESC does not have
an arming switch and will respond to any
transmitter input when a signal is present.
CAUTION: Always disconnect the Li-Po
battery from the ESC 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.
