I have just seen this thread and am amazed it took till post #6 for someone to say "DON'T USE THAT PROP" !!!!!! Get some better advice on how to balance a prop than what you have ATM. That prop and any others that you have balanced in that manner are a danger to you and anyone else at the field you fly at. I generaly don't get fazed when bad advice is given because there will always be some one else to post their opinion, but when safety is paramount then I got to say my piece. No attitude intended.
