Title: Prop Balancing
Post by: t michael jennings on February 04, 2010, 06:05:21 PM

Gentlemen,

When balancing a Prop, where is the best place to remove material?

    Trailing edge,
    Leading edge,
    Convex face,
    Concave face,
    Tips.                    :-[

Thanks for your replies.

On plastic/nylon props, get all the rough edges and flash sanded off and then balance by trimming tips.

Depends how much out of balance they are, if there close to balance then I just apply extra coats of paint or clear to the light blade, or if it's way out of balance I'll consider scraping it, or for out of production props I’ll sand with 400 grit wet n dry to the front of the heavy blade, and then do the paint or clear method. I try and avoid touching the back of the blades as it's easy to change the pitch unintentionally.

With carbon props, I take material off the back of the blade. But has been noted, you have to be careful with this so you don't change the pitch at the tip.
