Coordinator first thing to check, pot is probably loose. After that, take a serious look

at thermocouple harnesses. We had a lot of similar problems last few years that

were traced there. Also take a good look at the gimbal

bushings, and ALL control rod-end bearings. Also check

condition of the prop universal joint

 

Let us know what you found
