3 blades prop
« on: Yesterday at 12:41:36 PM »
I was balancing a 3 blade prop on my dubro balancer and noticed that one blade was higher than the other 2. In other words the tips of 2 blades would  track in the same spot but the 3rd blade at the tip would track 1/8" further. Anyone have this problem?

It may be just the imperfections in prop hole ends/balancer cones, the Dubro balancer is not very well made.
Check the tracking when bolted to the engine and if it bothers you, sand the bottom of hub to correct. L

It can make the prop noisy.
