Default prop balancing

i'm balancing a 3w 26 x 8 prop on a du-bro balancer
always stop on one side 9-3
this means that the hub is heavier on that down side?
thanks.Alex

I am assuming this is a two bladed prop.

Are you saying that when the prop stops the SAME tip is ALWAYS on the 'left'?

If so then the hole may be OFF CENTER or the hub is larger and/or heavier on that point that is now at the bottom.

I assume the balance unit does NOT have a rough spot right where it stopped.

Yes, it means that that half of the prop is heavier, not just the hub. You can balance it in several ways. You can spray clear on the respective leading edge of one blade and the trailing edge of the other or remove material from the heavy sides. You can also put screws into the light side of the hub. When properly balanced it should stay in any position you put it in.

If it's even tip to tip, but top/bottom heavy, that means that it's not out by much. You can make it better if you want to, but I wouldn't get too anal about it.

I know people do it but I would never remove material from a propeller. Always add some paint for weight.

I use to remove material, the problem is you then have unsealed wood and the balance changes. Now I use clear on the blade, hub. I've had some that were really bad and used screws on them. Most of the time paint works fine.
