If you have a TX that can be operated in eitherPCMor PPMmode, make sue the mode is set correctly for your RX. I cost me near $40 because I didn't check and sent the RX in for repair. The reciver and servos will act as you describe if the mode is wrong.

I will take closer look. I just a quick look with a pick. It didn't catch, but I will clean it and set some oil in the area and see if oil seeps through. I looked on tower for the arm but all I see is the carb.
Also another ? I have a confirmed good battery. When I flip the switch on, the servos twitch. When I try the controller, I get nothin. What should I check?
