RE: prop balancing
All prop balancers are not created equal. The top Flight Balancer is the best one for your 6-3 prop. For the props we are talking about , you need something with a little more capacity.
The tool man is talking about the way car tires are balanced. They are often done this way. This would bebecause one weight you have is too small and the next is too big or one is not enough and two's too many. You just spread them out on the wheel and you can get very accurate with your balance job.
Enjoy,
