Mini Apprentice

LVC is a feature 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.

Battery Precautions for Flight

• Keep the aircraft close until you are familiar with the ﬂ ight time.

• Do not ﬂ y to LVC (motors pulsing) repeatedly. This may result in battery

damage.

• Always disconnect and remove the ﬂ ight battery when ﬁ nished ﬂ ying.

Tip: Monitor your aircraft battery’s voltage before and after ﬂ ying by using a

Li-Po Cell Voltage Checker (EFLA111, sold separately).

TIP

Center of Gravity (CG) Veriﬁ cation

An aircraft with a correct CG has its weight balanced at a calculated point

where the entire airframe will balance when suspended at that point.

After installing the battery (in the recommended position) and before

powering on the ESC switch, verify the CG by supporting the aircraft 75.0mm

(approximately 2.95 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 in beginner mode, 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.
