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. 

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 4 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. 

Tip:

 Monitor your aircraft battery’s voltage before 

and after flying by using a Li-Po Cell Voltage 
Checker (EFLA111, sold separately).

Binding is the process of programming the receiver to recognize the GUID (Globally Unique Identifi er) 
code of a single specifi c 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. Please visit www.
bindnfl y.com for a complete list of compatible transmitters.

Low Voltage Cutoff (LVC)

Transmitter and Receiver Binding

Binding Procedure

CAUTION:

 When using a Futaba transmitter with a Spektrum DSM

®

 module, you must reverse the 

throttle channel and rebind. Refer to your Spektrum module manual for binding and failsafe instructions. 
Refer to your Futaba transmitter manual for instructions on reversing the throttle channel.

1.  Refer to your transmitter’s unique instructions for binding to a receiver (location of transmitter’s 

Bind control).

2.  Make sure the fl ight battery is disconnected from the aircraft.

3. Power off your transmitter.

4.  Connect the fl ight battery in the aircraft. The receiver LED will begin to fl ash rapidly (typically after 

5 seconds).

5. Make sure the transmitter controls are neutral and the throttle and throttle trim are in low position.

6.  Put your transmitter into bind mode. Refer to your transmitter’s manual for binding button or switch 

instructions. 

7. 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.
