Traditional Binding
For traditional binding, the binding phrase must be commented out in user_ defines on the RX.
- Power off your transmitter
- Plug in and unplug your receiver three times
- Make sure the LED is doing a quick double blink, which indicates the receiver is in bind mode
- Use the [BIND] button on the Express LRS Lua script, which sends out a binding pulse
- If the receiver has a solid light, it’s bound!
