Firstly love the jetstream 32 a beautiful aircraft. I finally sorted the joystick problems I was having, (plane skidding sidways RTM) Got to take off woot, Switched to Auto pilot, Altimeter set 5000, heading set 253 deg. Plane wanted to aim for the ground. Switched Auto Pilot off, and regained control, and maintained gentle climb to 5000. I then re started the auto Pilot and all seemed to be ok. Then about 5 minutes into the flight the "FD Pilot", "FD Co-Pilot" and "Auto Pilot On" started to flash and the plane went straight into a dive. (flaps at 5) Tried the same flight 3 times and did the same each time. I'm sure it's something I may have done or didn't, But i havn't had a problem with other aircraft. Has this problem been experienced before? Cheers Tim
