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 ma.

Start-Lock Function:

Start-Lock Function is the onboard brush ESC function from 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.
