    Connection Diagram

    Auto binding

    As it is difficult to reach the binding button when the receiver has been installed inside the plane, we developed self-binding function, it works like this: The receiver will enter binding mode automatically after powered and no signal for 15 seconds (slow flashing LED light turns to fast flashing), then complete the binding operation according to your transmitter binding manual.

    Start-Lock Function

    Start-Lock Function is the onboard brush ESC function of preventing brush motor from starting by mistake.  It can protect the brush motor from starting even throttle stick not at the lowest position when the receiver is powered.

    As soon as the receiver gets the signal and the throttle stick on your transmitter is at the lowest position for 2 seconds the first time, Start-Lock will be released then, the brush motor will run when the throttle stick is pushed.

    TELEM function

    TELEM function is useful on monitoring battery voltage, receiver working voltage and its signal strength as well as its working temperature in real time, through which customer can get working state of receiver and battery discharging state under control, so flying out of control range and over discharging will rarely happen ( for brushless motor rotation speed or flight height monitoring, customer needs to choose a more advanced receiver)

    NOTE: The effective control range of TELEM function depends on transmitter, it is possible that this would happen: the working range of the receiver is far more than TELEM function effective range, it is normal and alright!

    MA-RX42-X series receivers have the following 8 versions
