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/receiver 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 first
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. Attach the flight battery to the hook and loop
strip

(A) on the battery tray.

2. Lower the throttle and throttle trim to the

lowest settings on your transmitter.

Center of Gravity (CG)

The CG location is 37mm back from the leading
edge of the wing at the root. Adjust as needed by
sliding the battery forward or back.

3. 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 successful connection is indicated by:

– A series of tones

– A continuous LED

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.
