Battery Installation and ESC Arming
Battery Selection
We recommend the Spektrum 2200-3200mAh 11.1V 3S 30C Li-Po battery
(SPMX32003S30). If using a battery other than those listed, the battery should
be within the range of capacity, dimensions and weight of the Spektrum Li-Po
battery packs to fit in the fuselage. Be sure the model balances at the recom-
mended CG.
1. Lower the throttle and throttle trim to the lowest settings. Power on the
Transmitter, then wait 5 seconds.
2. Push the canopy latch button (
A
) to release the canopy and remove.
3. For added security apply the loop side (soft side) of the optional hook and
loop tape (
B
) to the bottom of your battery and the hook side to the battery
compartment.
4. Install a fully charged 2200mAh battery (
C
) all the way forward in the bat-
tery compartment as shown.
IMPORTANT
If you are flying with an FPV camera in the nose only, a 3200mAh
battery must be used to achieve proper CG. Adjust the battery position for
proper CG accordingly.
5. Connect the battery to the ESC. (the ESC is now armed).
6. Keep the aircraft immobile, upright and level, and away from wind or the
system will not initialize.
• The ESC will sound a series of tones (refer to step 6 of the binding
instructions for more information).
• An LED will light on the receiver.
• The elevons with cycle up and down two times to indicate that the aircraft
has initialized.
If the ESC sounds a continuous double beep after the flight battery is
connected, recharge or replace the battery.
7. Reinstall the canopy by inserting the front tab first and pushing down on the
back of the canopy until the latch locks.
