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 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. Install the flight battery towards the front of the
battery tray. Ensure the battery is secured by
the hook and loop strip.
Center of Gravity (CG)
Measure back 40mm from the leading edge of the
wing, where the wing meets the fuselage and place
a mark. Balance the airplane inverted on this CG
mark with all landing gear installed. This CG has
been found with the battery installed in the center
of the battery compartment.
2. Lower the throttle and throttle trim to the
lowest settings on your transmitter. Power
on your transmitter, then wait 5 seconds.
3. 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.
