WARNING:
Install the battery but do not connect it to the ESC while
checking the CG. Personal injury may result.
The CG location is 85mm (+/– 5mm) back from the leading edge of the wing at the
fuselage.
Always check the CG location with the landing gear down.
The CG location is adjusted by moving the battery pack forward or backward in the
battery compartment.

Battery Selection
A 6S 4000-8000mAh LiPo battery is required. The Spektrum 5000mAh 22.2V 6S
30C LiPo battery (SPMX50006S30) is recommended. 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 Li-Po battery packs to fi t in the fuselage. Be sure the model balances at
the recommended CG before fl ying.
1. Lower the throttle and throttle trim to the lowest settings. Power on the
transmitter, then wait 5 seconds.
2. Remove the battery hatch.
3. For added security, apply the loop side (soft side) of the optional hook and loop
tape to the bottom of your battery, and the hook side to the battery tray.
4. Install the fully charged battery in the center of the battery compartment as
shown. Secure using the hook and loop straps.
5. Connect the battery to the ESC. If you have not completed the bind sequence,
do so at this time as outlined in this manual.
CAUTION:
Always keep hands away from the fan intake. When armed, the
motor will turn the rotor in response to any throttle movement.
6. Keep the aircraft immobile and away from wind or the system will not initialize.
• The motor will emit a series of rising tones when the battery is connected,
and then 6 even tones indicating the number of cells connected.
• An LED will light on the receiver when it is initialized
7. Reinstall the battery hatch.
