  1. Thank you guys! I will contact Bob now! Best regards, Lino
  2. OK Thank you carusoam, I will try it as soon as I can reach the airport, within this week probably. Then I will let you know. Thanks again and have a nice week. Lino
  3. Thank you carusoam. I already opened the wing....an avionic engineer working on ultralight but expert enough, suggested me to let the servo been checked (there is electronic inside), pull it out and send to somebody for a check. However this does not convince me because the main issue to me is the energy that should not reach the servo until the AP is activated. Yes to me also looks somethink more autopilot related rather than servo related...sound of a relay blocked....
  4. Hello! PT20J: Yes it is a circuit breaker...pulling it out (that of the autopilot) the noise stops (sorry I am not english mothertongue). As soon as I switch Master on and Radio/Avionic ON I can hear the noise. I did not try to push the red switch on the Yoke as I never engaged the autopilot, can be worth to try but of course if I provide supply why should this reach the servo if the autopilot is disengaged....?) CARUSOAM: The servo is mounted on the right wing, type KS271. It is made up of the Roll Servo+Mount, that is KS271+KM275. Yes I guess there is a clutch as otherwise I cannot explain why it makes this noise (guessed rotation) and works correctly because it acts on the alieron actually when autopilot is engaged. However the suspect fact is this guessed rotation even with autopilot disengaged (to me when autopilot is disengaged no power supply should reach the servo.....)
  5. Hello carusoam, autopilot is a KFC200.....yes I am up early....live in Austria
  6. Hello to everybody! Just joined the forum, I would like to ask the help of somebody. I purchased recently a Mooney M20K 231. In the right wing close to the end there is a Roll Servo KS271 with its mount KM275. As soon as I switch the Master switch even with Autopilot disengaged, I hear a noise coming from the servo such as something is permanently rotating inside. As I engage the autopilot it activates the Ailerons otherwise not of course. Autopilot in flight works correctly. If I take out the autopilot fuse this noise stops. Is it normal even if the autopilot is disengaged to have this permanent noise (I guess it is a rotation...)? If this is a problem, is it to guess a malfunctioning of the Roll Servo and its electronic inside or of the autopilot? I thank you very much for your help! Lino, Austria
