    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 

    Thanks defect has been solved (wiring Defective/intermittent)
