Battery Installation and ESC Arming
Battery Selection
The Spektrum 2200mAh 14.8V 4S 30C Li-Po battery (SPMX22004S30) is
recommended. The SPMX22003S30 battery may also be used. For maximum
performance with 3 cells, a 13 X 6.5 electric propeller may be utilized. 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.
WARNING: Always keep hands away from the propeller. When armed,
the motor will turn the propeller in response to any throttle movement.
1. Lower the throttle and throttle trim to the lowest settings. Power on the
transmitter, then wait 5 seconds.
2. Press the latch button (B) and remove the battery hatch.
3. 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.
4. Install the fully charged battery (C) in the center of the battery compartmant
as shown. Position battery forward or aft for your desired CG. Secure using
the hook and loop straps (D).
5. Connect the battery to the ESC (the ESC is now armed).
6. Keep the aircraft immobile, upright, and away from wind or the system will
not initialize.
• The Avian Smart ESC will sound a single tone every two seconds until
the receiver initializes. it will then sound either 3 or 4 tones in quick
succession indicating the battery cellcount, and a double tone indicating
it is initialized.
• An LED will illuminate on the receiver when it is initialized
If the ESC sounds a continuous beep after the receiver is initialized, recharge or
replace the battery.
7. Reinstall the battery hatch.
Center of Gravity (CG)
WARNING: If your transmitter allows it, always engage throttle cut
before approaching the aircraft.
CAUTION: Install the battery but leave it disconnected while checking
the CG. Personal injury may result if battery is connected while
checking CG.
The CG location is measured from the leading edge of the wing at the root.
This CG location has been determined with the recommended Li-Po battery
(SPMX22004S30).
A pocket in the tail provides a space for extra tail weight for pilots wanting to
push the 3D capabilities to the limit. Extra tail weight is not included.
(without slats installed)

• 102mm +/- 3mm back from the leading edge with the
steel joiner for maximum 3D performance
