The BMR Series receiver is even smaller and lighter than the previous version. This full-range, the receiver has push upon power up, the receiver learns the characteristics of your transmitter like positive (JR/Airtronics) or negative (Futaba/Hitec) shift, number of channels, trigger pulse length and approximate frame rate. Once learned, the receiver locks onto your transmitter and rejects signals from other transmitters that have different characteristics. Finally, it has a programmable fail-safe function. In the event of a signal loss, it can be programmed to hold the last good servo positions, and upon extended signal loss, automatically switch to pre-programmed servo positions that you can set.

Automatic lock onto TX signals.
