Thought that I would try and make things as smooth as possible by doing a Dynamic Prop Ballance. I am flying a 68 SC with a Lycon rebuilt O-320 (160) with about 630 Hrs on it. Borer 44/41. Many have said it was one of the smoothest Cubs they had flown in as it is, but I had planned to mount a new camera and wanted to take out all the vibration that I could. There was a little vibration in cruse (2350 - 2400), so I thought what the heck, just had an Annual in Oct. where I replaced a cracked spinner back plate, so figured now would be the time.
Bottom Line, after changing some weight around on the propeller and adding a couple washers to the spinner, spinner (On-Off) four run ups - it vibrates worse. Not bad, just noticably worse. There is vibration in the Stick and Peddles that wasn't there before. The quick fix would be to (Put everything back the way it was), so here is the question.
During static run-up, which was about 2370 RPM, is there any flexing going on with the prop that would cause the ballancer to give a unreliable reading? Say compared to Non-Static (flight mode) Still would like to get things as smooth as possible. I do understand that it is a Cub and should have some lee-way in my expectations.
