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 also occurs after binding as
previously described, but subsequent connection of a flight
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. Remove the battery hatch from the fuselage.
2. Attach the battery to the hook and loop strip so the
battery is against the motor mount.
Center of Gravity (CG)
At the wing root, measure the CG location 32mm back
from the leading edge of the wing at the center section.
3. Lower the throttle and throttle trim to the lowest set-
tings 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.
Spektrum or E-flite 2S batteries with a PH plug require
an adapter lead. (SPMXCA327).
CAUTION: Always disconnect the Li-Po battery
from the ESC when not flying 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 flying 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 fire when batteries are charged.
