Yep you need the adaptor for the 9C. That is what I fly, just remember to take your frequency module out when you are flying the sim. Its better for your radio and it makes the batteries last WAY longer.

I have a weird grounding issue and get a lot of fliker in the control surfaces similar to interference. I think its because my house has the old 2 wire configuration and there is no true green wire to ground.

I solved teh problem by making a jumper that is taped to the usb cord, it sis clipped tot he metal frame of the computer tower and I hold the other little clip in my left pakm. Makes a perfect ground, no interference and I dont even know its there. I guess I can throw it away if I ever move or rewire my house.
