Flight Battery Installation And Esc Arming; Low Voltage Cutoff (Lvc) - Horizon Hobby E-flite Bind-N-Fly UMX FPV RADIAN Mode D'emploi

Flight Battery Installation and ESC Arming

Arming the ESC also occurs after binding as
previously described, but subsequent connection
of a fl ight battery requires the following steps.
It is normal for linear servos to make noise. Noise
is not an indication of a faulty servo.
The AS3X ® system will not activate until the
throttle stick or trim is increased for the fi rst
time. Once active, the control surfaces may
move rapidly and noisily on the aircraft. This is
normal. AS3X technology will remain active until
the battery is disconnected.
CAUTION: Always keep hands away
from the propeller. When armed, the motor will
turn the propeller in response to any throttle
movement.
CAUTION: Always disconnect the Li-Po
battery from the aircraft receiver 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.

Low Voltage Cutoff (LVC)

When a Li-Po battery is discharged below 3V per
cell, it will not hold a charge. The aircraft's ESC
protects the fl ight battery from over-discharge
using Low Voltage Cutoff (LVC). Once the battery
discharges to 3V per cell, the LVC will reduce the
power to the motor in order to leave adequate
power to the receiver and servos to land the
airplane.
When the motor power decreases, land the aircraft
immediately and replace or recharge the fl ight
battery.
Lower throttle and

FLY...
Always disconnect and remove the Li-Po battery
from the aircraft after each fl ight. Charge your Li-Po
battery to about half capacity before storage. Make
sure the battery charge does not fall below 3V per
cell. Failure to unplug a connected battery will result
in trickle discharge.
For your fi rst fl ights, set your transmitter timer or a
stopwatch to 5 minutes. Adjust your timer for longer
or shorter fl ights once you have fl own the model.
NOTICE: Repeated fl ying to LVC will damage the
battery.
