I've been balancing my props for quite some time but no one has ever answered this question: (I'm using a DuBro Balancer)

There are 4 different 'positions' you can positions (or orienations) the prop on the balancer - I can get three to balance perfectly - but there is always one position that indicates a heavy blade....is the prop balanced or not?

Thanks for your thoughts....

I just looked up the dubro balancer, I don't know what you mean by 4 positions. seems to me once the axel is laid on the balancer the heavier blade will rotate down...Oh I think I may have it do you mean the nbr 1 blade left,then up, then right.then down? if so as long as it moves you have a heavy blade.

tailskid,

Here is a nice video on how to balance a prop.

I used to balance high-speed grinding wheels. These things had to be perfect.

If you're balancing a prop, it doesn't have to be nearly as critical, but the same rules apply.

First, don't think of the prop as a 2-sided stick, think of it as a disk.

The video above shows how once the blades are balanced, you will still need to balance the other areas of the "Disk"

Now, that said, if the baldes are balanced, that is plenty good enough for any prop under 15"

Great Video....and I've never balanced the hub! Now I know how....thanks for the link!
