LuftwaffeOberst,
No, there isn't excessive vibration in my planes. The plane that has over 400 flights on it has very little or no vibration issues in it. Excessive vibration comes from a problem that is extremely out of balance, and if you read my post I pointed out that I don't use props that are that far out of balance. A small bit won't cause vibrations like you describe, especially at the speeds that these props spin at.
