ESC/Receiver Arming and Battery Installation
8mm
The CG location is 8mm forward of the panel line shown in
the illustration. This CG location has been determined with
the recommended battery. Check the CG with the model
inverted. Adjust the battery forward or aft so the model
balances level at the recommended point.
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 above 25% 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. Open the battery hatch.
2. Attach the battery to the hook and loop strip so the
battery is centered in the battery cavity.
3. Lower the throttle and power on your transmitter. En-
able throttle cut switch.
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 (LED may be difficult to
see as it is located inside of aircraft.) indicates a suc-
cessful connection.
A solid blue LED indicates that the aircraft is in SAFE
flight mode and a solid RED LED indicates that the
aircraft is in AS3X flight mode. When the aircraft is in
SAFE the servos will move without increasing throttle
above 25% throttle
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.
