Note: The DSMX receiver used on the 65x and 75x is different from the one we used before.
There's no a bind button on this FULLSPEED receiver and the binding procedure is also completely different.
1. Connet the receiver to FC and run the Betaflight. Choose the correct port and type of your receiver on the flight controller.
2. Type: set spektrum_sat_bind=3 in CLI and save.
3. Repower the receiver. The light on the receiver will flash rapidly, which means it's on binding mode.
4. Turn on the radio and select bind mode. Wait a moment. It means bind successfully if the light on receiver keeps solid.
