Battery Installation and ESC Arming
Battery Selection
A 3S or 4S 4000-5000mAh LiPo battery is required. The E-fl ite
®
4000mAh 14.4V 3S
30C Li-Po battery (EFLB40004S30) 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 E-fl ite Li-Po
battery packs to fi t in the fuselage.
NOTICE: Nose weight will need to be added for lighter batteries. Always verify the
model balances within the recommended CG range before fl ying. Attempting to fl y
the model with an aft CG will cause the model to be unstable
1. Lower the throttle and throttle trim 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 to the bottom of your battery, and the hook side to the battery tray.
3. Remove the battery hatch.
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 (the ESC is now armed).
CAUTION: Always keep hands away from the propeller. When armed, the
motor will turn the propeller 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 two even tones when the battery is connected and the
ESC has a throttle signal.
• The motor will then emit a series of slow single tones to indicate the number
of cells in the LiPo pack connected to the ESC (Three beeps indicates a 3 cell
LiPo pack. Four beeps indicates a 4 cell LiPo pack).
• Two ascending tones indicate the ESC is armed.
• The orange LED will illuminate on the receiver when it is initialized.
7. Reinstall the battery hatch.

Center of Gravity
The Center of Gravity (CG) location is measured from the leading edge of the wing
at the root. The CG will be affected by cargo or battery changes. Always verify the
CG is within the recommended range before fl ight.
IMPORTANT: For general fl ying place the CG at 65mm from the leading edge. For
aerobatics place the CG at 75mm from the leading edge.

65-75mm
Caution: Install the battery but do not arm the ESC while checking the CG.
Personal injury may result.
