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

ﬂight 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 ﬂying to LVC will damage the battery.

1. Rest the aircraft on a ﬂat surface with the landing gear facing up and

make sure the ESC switch is OFF.

2. Turn the latch (A) and open the battery hatch.

3. Lower the throttle and throttle trim, then power on the transmitter for at

least 5 seconds.

4. Center and secure the ﬂight battery (B) in the battery compartment using

the hook and loop straps (C) so that the aircraft has a balanced Center of

Gravity (CG).

IMPORTANT: Before ﬂying, refer to the “Verifying Your Aircraft’s Center of

Gravity (CG)” section for details about ﬁnal battery placement.

5. Connect the ﬂight battery in the aircraft, then replace the battery hatch

and turn the latch.

6. Put the aircraft on its landing gear, then power on the ESC Switch (D). The

aircraft should be on level ground and must be kept immobile while the

SAFE system initializes. If the aircraft moves during initialization, power

off the ESC Switch and power it on again to re-initialize the system.

7. After the SAFE system initializes, the control surfaces will move back and

forth, then come to neutral to indicate the SAFE system has initialized and

is ready to operate.

If you accidentally connect the battery while the throttle is fully opened, a musi-

cal tone will sound after 5 seconds and the ESC will enter programming mode.

Immediately power off the ESC switch and go back to step 5.

IMPORTANT: SAFE technology is not active until you advance the throttle past

25%. Once it is active, the control surfaces may move on the aircraft. This is

normal. The SAFE technology will remain active until the ESC is turned off.

CAUTION: Always disconnect the Li-Po ﬂight battery from the aircraft

receiver when not ﬂying 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 ﬁre 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.

Battery Precautions for Flight

• Keep the aircraft close until you are familiar with the ﬂight time.

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

damage.

• Always disconnect and remove the ﬂight battery when ﬁnished ﬂying.

Keep immobile and

out of the wind for

5 seconds

Monitor your aircraft battery’s voltage before and after ﬂying by using a

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