Hello Barry
No problem just thought you maybe away or something.
Once you get the autopilot engaged, not ALT HOLD what rate of climb or decent do you get, should be about 700 ft min climb max and about 1200 ft min decent.
If you have had all the gyros and autopilot away for checking it sounds like the pitch servo needs recentering.
What is happening is in the climb the followup system in the pitch servo is going out of range, so the gyro signal cannot sync with the pitch attitude of the aircraft so the pitch wheel goes up or down to the stop and the motor keep running. If you lower the nose by pushing forward on the column you will find that it will engage at a low rate of climb.
You need to reset the pitch servo. I can copy this out of the manual but it is a tricky job as the elevator has to be set to the right position for neutral, have you somebody out there that can do this?
Let me know
Regards
Pete
