When a Li-Po battery is discharged below 3V per cell, it
will not hold a charge. The aircraft’s ESC protects the flight
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 im-
mediately and replace or recharge the flight battery.
Always disconnect and remove the Li-Po battery from
the aircraft after each flight. 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 first flights, set your transmitter timer or a stop-
watch to 5 minutes. Adjust your timer for longer or shorter
flights once you have flown the model.
NOTICE:
Repeated flying to LVC will damage the battery.
Low Voltage Cutoff (LVC)
Binding is the process of programming the receiver to recognize the GUID (Globally Unique Identifier) code of a single
specific transmitter. You need to ‘bind’ your chosen Spektrum
™
DSM2/DSMX technology equipped aircraft transmitter to
the receiver for proper operation.
Any full range Spektrum DSM2/DSMX transmitter can bind to the DSM2/DSMX receiver.
Transmitter and Receiver Binding
Binding Procedure
1. Refer to your transmitter’s unique instructions for binding to a receiver (location of transmitter’s Bind control).
2. Make sure the flight battery is disconnected from the aircraft.
3. Power off your transmitter.
4. Place the aircraft on a level surface away from wind.
5. Connect the flight battery in the aircraft. The receiver LED will begin to flash rapidly (typically after 5 seconds).
6. Make sure the transmitter controls are neutral and the throttle and throttle trim are in low position.
7. Put your transmitter into bind mode. Refer to your transmitter’s manual for binding button or switch
instructions.
8. After 5 to 10 seconds, the receiver status LED will turn solid, indicating that the receiver is bound to the
transmitter. If the LED does not turn solid, refer to the Troubleshooting Guide at the back of the manual.
For subsequent flights, power ON the transmitter for 5 seconds before connecting the flight battery.
