I have the exact same problem with my Futaba 9C radio. It used to work but now everytime I connect it all the channels go wild. It doesn't do it with the other controler (a cheap futaba that came packaged with a trainer). The weird thing that I just realized is that it does it only when you touch the top of the radio (just touching the bottom and sticks is ok but there's no way you can practice like that). I also tried it with a brand new 9c super and it does the same thing. I have APFD which I upgraded to 18025. Any solutions?
