Ok, I bought the Top Flite Power Point Balancer last night at the LHS and three props. All the props were Master airscrew brand G/F Series. One was a 10x6, 10x7 and I had one that wouldn't balance, it was the 11x6 prop.

This is what it was doing. This is from the manual.

If the prop comes to rest in a
level position, but is still obviously out of
balance (hole slightly off-center), you
may need to add weight to the lighter
side of the hub (see method 2).

I had a glob of ca glue on the light side but it would not balance out. Did I just get one lemon of a prop? The other ones balanced perfectly.
