Battery Installation and ESC Arming

Battery Selection
We recommend the 2200mAh 14.8V 4S 30C Li-Po battery (SPMX22004S30).
Refer to the Optional Parts List for other recommended batteries. If using
a battery other than those listed, the battery should be within the range of
capacity, dimensions and weight of the Spektrum Smart Li-Po battery packs to
fit in the fuselage. Be sure the model balances at the recommended CG.
1. Lower the throttle to the lowest settings. Power on the transmitter, then
wait 5 seconds.
2. For added security apply the loop side (soft side) of the optional hook and loop
tape (A) to the bottom of your battery and the hook side to the battery tray.
3. Press the battery latch button (B) to remove the battery hatch.
4. Install the fully charged battery (C) in the battery compartment as shown.
See the Adjusting the Center of Gravity instructions for more information.
5. Make sure the flight battery is secured using the hook and loop straps (D).
6. Connect the battery to the ESC (the ESC is now armed).
7. Keep the aircraft immobile on its landing gear and away from wind or the
system will not initialize.
• The ESC will sound a series of tones.
• An LED will light on the receiver.
If the ESC sounds a continuous beep after the flight battery is connected,
recharge or replace the battery.
8. Reinstall the canopy hatch.
WARNING: Always keep hands away from the propeller. When armed,
the motor will turn the propeller in response to any throttle
movement.
WARNING: If your transmitter supports it, always engage throttle cut
before approaching the aircraft any time a battery is connected.
