If the problem is the harness, I donít understand why the left mag ran smoothly during the previous flight. Nothing in the harness was touched or changed.
Iíll post the results of the next flight, hope both mags run smoothly.
I had a harness problem - and it was very difficult to track down. Slight movement of the cable would cause it. After finding it and fixing it I'm really amazed at the increase in smoothness.
I would not discount the harness.
