Hey, im building a drone using this youtube guides:
So, im stuck in binding the remote controller to the VTX reciever, when I connect the battery I get a few beeping sounds and then its quiet, and a red flashing on the SP3 flight controller and on his other side blue steady light. So i connected the bind key to the B/VCC port and the power cable to one of the available ports. I click bind on my flight controller while I turn it on and it writes binding… but nothing happens, tried many times to figure it out with no success, waiting for you help, thank you.
Forgot to mention im new in building this its my first time building drone or any rc at all.
by the way I didnt flash any software to the quad, I dont know if its related, but when I tried to connect it with betaflight and cleanflight it recognized once with betaflight so I checked its version becuase only the CLI worked (cleanflight january 2016), but after I accidently exit the program without dissconnecting from the quad it didnt connect to the drone anymore, not with betaflight and not with cleanflight.
