If you accidentally connect the battery while the throttle is fully raised, the ESC will enter programming
mode. Disconnect the battery immediately.
The AS3X system will not activate until the throttle stick or trim is increased for the fi rst time. Once the AS3X
is active, the control surfaces may move rapidly on the aircraft. This is normal.
AS3X will remain active until the battery is disconnected.
NOTICE: Always keep material or debris away from the intake. When armed, the rotor will turn in response
to the throttle movement and could ingest in any loose objects.
Arming the ESC
Arming the ESC also occurs after binding as previously described, but subsequent connection of a fl ight
battery requires the steps below.
Lower throttle and throttle
trim to lowest settings.
Power on the Transmitter
then wait 5 seconds
Install fl ight battery and
connect it to the ESC. Keep plane immobile
and away from wind for
5 seconds.

Low Voltage Cutoff (LVC)
When a Li-Po battery is discharged below 3V per
cell, it will not hold a charge. The aircraft’s ESC
protects the fl ight battery from over-discharge using
Low Voltage Cutoff (LVC). Before the battery charge
decreases too much, LVC removes power supplied
to the motor. Power to the motor quickly decreases
and increases, showing that some battery power is
reserved for fl ight control and safe landing.
When the motor power pulses, land the aircraft
immediately and recharge the fl ight battery.
Disconnect and remove the Li-Po battery from the
aircraft after use to prevent trickle discharge. During
storage, make sure the battery charge does not fall
below 3V per cell.
Tip: Due to the quiet nature of the aircraft, you may
not hear the pulsing of the motor.
For your fi rst fl ights, set your transmitter timer or a
stopwatch to 3 minutes. Adjust your timer for longer
or shorter fl ights once you have fl own the aircraft.
Flights of 4 minutes or more are achievable if using
proper throttle management.
NOTICE: Repeated fl ying to LVC will damage
the battery.
