I bought an old Airtronics Infinity 6600 complete with 4 servos, RX, batteries, harness, etc. Operating PCM on Ch. 55. I'm still building the airplane but I powered everything up on the bench, including the aileron servo installed in the wing.
All 4 servos respond properly to commands from the TX but then they all begin "chattering". Vigorous, rapid, random, back and forth movement of the output wheels. They will sometimes stop chattering and behave normally, then start again randomly.
Has anyone experienced this problem and have an idea what causes it?
I haven't gone back to investigate yet. My only thought is that maybe I was overdriving the receiver. The antennas were only a foot or so apart.
I'll appreciate your thoughts.
