I have two Turnigy 9x transmitters and would like to set them up as a buddy box system for flying FPV safely at the club. I've read somewhere that with the FrSky DIY kit installed there are some issues with master/slave set-up, something to do with both transmitters transmitting or something. Truth is, I can't remember.
Anyone know what the correct procedure is?
Also, can you use different Tx brands to buddy box or must they both be the same make and model?
