Hi Everyone:
I am building a 210mm quadcopter with a SP Racing F3 V1 flight controller and an Spektrum AR610 PWM reciever. I am totally baffled how to wire the reciever to the Control board. Everything else seems to work but the AR610 is not communicating properly with the F3 board. I am using Cleanflight which comes with the F3. I am a casual flyer and have built quads before. Any advise would be great. The only video on YouTube I have found that adresses the issue directly is from 2015 and I am afraid the information is dated. Thanks in advance. Captain V
