Hey Downunder,

I have a finger balancer and I used it between two identical drink glasses. When I bought my Dubro balancer, I went back and checked some props. They were all out and needed rebalancing. The finger balancer still got me close.

I once landed a plane with only one engine mount bolt left. Two were missing. One had backed all the way out and was trapped by the engine. I was using a 3 bladed prop that had never been balanced. I later found it out of balance by an unbelieveable amount. Looking back, this is probably why I lost a main gear on that same plane about a week before. I came in to land the gear left the plane cleanly. It had popped the heads off of the plastic bolts as they had both vibrated out a few turns.
