Battery Installation and ESC Arming

Battery Selection

We recommend the E-ﬂite

2200-3200mAh 11.1V 3S 30C Li-Po battery

(EFLB32003S30). If using a battery other than those listed, the battery should

be within the range of capacity, dimensions and weight of the E-ﬂite 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.

CAUTION: Always

keep hands away from the

propeller. When armed, the

motor will turn the

propeller in response to

any throttle movement.
