Like Ed said ...

Balancing tip to tip is easy, but what about the hub, it can have a heavy side. Lay a prop on a table, 3 and 9 oclock. Now look at the hub, look at 12 and 6 oclock. One of those sides can be heavy.

1. Using my trusty top flite balancer I balance tip to tip, set prop tips at 9 and 3 oclock and balance until perfect.
2. Now rotate prop to 2 and 8 oclock, and watch which tip drops. If the right drops, the bottom of the hub is heavy. Now try it at 10 and 4 oclock. You get the picture.
I have balanced a hub by using just a few drops a ca on the light side of the hub. With larger props you'll need to ca some velcro (not the fuzzy side) to the light side and then begin to drop ca into it.
Now that you have it all balanced you can rotate the prop anywhere and it will stay there. Give it a try.

A properly balanced prop will come to rest at any position on the balancer. So to balance the prop, remove or add weight to the blades and hub as previously described. Sometimes it balances quickly. Sometimes a fair amount of time can be spent "Chasing" the out of balance part around.

An out of balance condition caused by the hub can be just as detrimental to the engine, radio, and airplane as out of balance blades.

Amen to that. Sooo many people never balance props properly. If you do what Ed said, you'll be fine.
