Battery Installation and ESC Arming
Battery Selection
A 3S 2200-3200mAh LiPo battery is required. Refer to the Optional Parts List for
battery recommendations. If using a battery other than those listed, the battery
should be within the range of capacity, dimensions and weight of the E-ite Li-Po
battery pack to t in the fuselage.
CAUTION: Add nose weight for lighter batteries. Always verify the model
balances within the recommended CG range before ying. Attempting to
y the model with an aft CG will cause the model to be unstable.
CAUTION: Never adjust the CG while a battery is connected.
CAUTION: When replacing the wheels with oats, recheck the CG. Place
the battery further forward to compensate for the CG change.
1. 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.
2. Remove the battery hatch.
3. Install the fully charged battery in the center of the battery compartment as
shown. Secure using the hook and loop straps.
4. Connect the battery to the ESC. Two beeps indicate the ESCs are armed.
CAUTION: Always keep hands away from the propeller. When armed, the
motor will turn the propeller in response to any throttle movement.
5. Keep the aircraft immobile and away from wind or the system will not
initialize.

ESC has a throttle signal.
The receiver LED will illuminate orange when it is initialized.
Fast continuous beeps indicate the ESCs are not armed.
6. Reinstall the battery hatch.

at the root. The CG will be affected by cargo or battery changes. Always verify the
CG is within the recommended range before ight.
IMPORTANT: Place the CG 45mm (±5mm) from the leading edge.
