Note: Binding process. power up the drone 3 times, on the third time you plug in power, the ELRS Receiver will get into binding mode. We are still trying to work on the ELRS firmware and make it able to just click the boot button to get into bind mode. Will get this update in the near future. 
Check out the video below CiottiFPV show you how to get into bind mode. - Thanks bro for showing this. lol
