Hitec Optic 6 Sport 2.4GHz PPM???
I have Optic 6 Sport 2.4GHz radio (http://www.hitecrcd.com/products/air...rt-2-4ghz.html) and now I have a small problem with it.
I'm trying to change the Hitec Spectra TX to FRsky DHT DIY, but I'm not able to get it working as it should. 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...

There are five points in the circuit board, which are CHG, RF+, G, B+ and S. I made the connection to points RF+ to FRsky +, G to FRsky - and S to FRsky Signal. With this connection servos are moving all the time, after I connect RX to the battery with TX on. I was eliminating possible FRsky TX or RX fault by connecting it to my own Graupner MX-22, and everything worked like charm. So I think that Optic 6 Sport 2.4GHz AFHSS is not using PPM from radio to TX????
The main reason I want to change Hitec's 2.4 GHz Spectra AFHSS to FRsky is that we fly sometimes same models with my son. Now we have to change RX inside the plane, because I'm flying with Graupner MX-22 and FRsky 2.4GHz. If we had both radio's with FRsky, then only to BNF (bind and fly) is all what's needed.
