RE: Vibration Problems Caused by Gas Power
I have found by balancing the prop at 12, 1:30, 3, 4:30, 6, 7:30, 9, 10:30 fixed my vibration problems.
Had one prop off a quick spray of lacquer and it made the cowl shake ~1/8. After balancing as above, now smooth and no shakes.
This was on a DA100, 36% AW Katana.
