Verifying Your Aircraft's Center
of Gravity (CG)
An aircraft with correct CG has its weight balanced on the
center of the aircraft for safe, stable fl ight.
Verify the CG by supporting the aircraft 45mm (approxi-
mately 1.75 inches) back from the front edge of the wing,
as shown.
Tip: Balance the aircraft on your fi ngertips 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 fl ying with correct CG, the aircraft should climb
gradually at full power and fl y level at 50%–60% power
with no elevator input.
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.
Adjust the battery position as needed.

LVC (Low Voltage Cutoff)

LVC is a mechanism built into your ESC to protect the
battery from over-discharge. When the battery charge
is too low, LVC limits power supplied to the motor. The
aircraft will begin to slow and you will hear the motor
pulse. When the motor power decreases, land the aircraft
immediately and recharge the fl ight battery.
Disconnect and remove the Li-Po battery from the aircraft
after use to prevent trickle discharge. Charge your Li-Po
battery to about half capacity before storage. During
storage, make sure the battery charge does not fall below
3V per cell.
NOTICE: Repeated fl ying to LVC will damage
the battery.
