Battery Selection
• We recommend the E-fl ite
®
1300mAh 11.1V 3S 20C
Li-Po (EFLB13003S20).
• If using another battery, the battery must be at least a
1300mAh battery.
• The battery should be approximately the same capacity,
dimensions and weight as the E-fl ite Li-Po battery to fi t
in the fuselage without changing the center of gravity a
large amount.
1. Lower the throttle stick to the lowest setting and center
the throttle trim. Power on the transmitter, then wait 5
seconds.
2. Apply a strip of hook tape
(A)
to the bottom the battery
near the end opposite the battery wires.
3. Turn the latch
(B)
and open the battery hatch.
4. Install the fl ight battery as shown. See the Adjusting the
Center of Gravity instructions for more information.
5. Make sure the fl ight battery is secured using the hook
and loop strap
(D)
.
6. Connect the battery to the ESC. Close the hatch and turn
the aircraft over and place it on its wheels. Keep the
aircraft immobile and away from wind for 5 seconds.
7. Keep the aircraft immobile for 30+ seconds until GPS
lock is established as described in the Flying section.
CAUTION:
Always disconnect the Li-Po fl ight
battery from the aircraft when not fl ying to avoid
over-discharging the battery. Batteries discharged to a
voltage lower than the lowest approved voltage may
become damaged, resulting in loss of performance and
potential fi re when batteries are charged.
CAUTION:
Always keep hands away from the
propeller. When armed, the motor will turn the
propeller in response to any throttle movement.

An aircraft with the correct CG has its weight balanced on
the center of the aircraft for safe, stable fl ight.The aircraft
CG and weight are based on an E-fl ite 11.1V 1300mAh
30C battery (EFLB13003S20) installed. Make sure the
fl ight battery is secured using the hook and loop strap.
The CG location is 62-68mm back from the leading edge
of the wing at the root. Balance the aircraft on your fi nger-
tips near the fuselage under the wings.
• If the nose goes down, move the fl ight battery back
until the aircraft balances.
• If the nose goes up, move the fl ight battery forward
until the aircraft balances.
When in intermediate and experienced modes, if the
aircraft CG is too far forward (nose heavy), up elevator is
required to fl y level at 50%–60% power. If the aircraft CG
is too far aft (tail heavy), down elevator is required to fl y
level. In Beginner mode the aircraft is not affected. The
SAFE Plus system controls the aircrafts attitude.
Adjust the battery position as needed.
