I used my 9Z last night to check some servos, worked fine. I got it back out tonight to check couple of more and now the radio does not transmit. It comes on as usual and the "on air" is flashing and shows channel 55. But it will not work any servoes. I changed the model to my Giant Stinger I have been flying and it does not work either. The servoes do not move at all. I pulled the synthesized module and replace it thinking it might have lost contact, but still no transmit.
Any ideas?
Thanks,
James

Found the problem, radio was on PPM not PCM. but I do not know how this got changed.
