RE: Hitec 55's with FMA receiver?
I have an M5 with HS-55 servos. After two non-eventful flights I thought everything was peachy. The second time out on a fully charged battery nothing worked. When I turned on everything would stay at neutral. It turned out that I could hold full up elevator (for example) when turning on the reciever and it would go full up and then everything would freeze. I stuck it in the car for a few hours and when I tried it later in the day it worked fine. The battery had been off charge for several hours the first time I tried it as well.
I know this isn't the same problem the original post mentioned and I'll definately check for "chirping" the next time out.
