I can bind FRsky TX and RX, but when I connect servos on RX and turn it on, servos are moving all the time. Now I have doubt that my Hitec radio signal to Spectra TX is not PPM. Is it??? If it's not, is there a soldering point inside radio, where I can find PPM??
I'm trying to do this FRsky mod to Hitec, which is my son's radio. And the reason because I want my hole fleet to be flown both radio's without having to change RX's on them. I fly myself with Graupner MX-22 with FRsky DJT module.For the record, I tested the same FRsky DHT TX in my Graupner MX-22 and everything worked like a charm:
So any help for me...
