[Paparazzi-devel] Question regarding servo motor

Hello all,
        I have started using the new paparazzi distribution for fixed-wing. Everything works fine for my implementation except the servo motors. Both of my servos jitter even under manual mode, and the right servo got burned out today after a long testing.
        The strange thing is that when I moved the joystick handle, sometimes the jitter just disappeared, then it came back again. I tried to seal my servo with copper tape and added a glitch buster, didn't help. I also tried to play with the servo parameters (min, neutral, max), didn't get solved either.
        I also noticed the old PPM_FILTERING code doesn't exist any more, wondering whether that should help.
        I am using Hitec MG-82 servos. Anyone has had similar problems? Any inputs are appreciated.
