I've been asking my club members the proper way to balance a prop. Some say, "sand the heavy end," others claim that will mess up the aerodynamics of the blade and you should sand the blade near the hub. The first group says that will make the blade weak. Additionally, is there a difference for wood vs the APC props?

Thanks,

Jim

What I have found as a good alternative to sanding the prop is to put a coat of colored dope on the tip (about 3/8 - 1/2 inch wide) of the light end. There is no chance of weaking the blade and the color on the tip helps you to avoid accidently "feeding" the engine

Personally, while I like the appearance of a wood prop, I use APC props on most of my planes. The APC props are less fragile than a wood blade, just as efficient (and more efficient than some brands ) and are USUALLY balanced (check them anyway just to be sure ).

I use thick CA on the heavy end (on the back). Use one drop, and let spread out, then set it with kicker. Too much, just sand it down. It's quick, easy and doesn't weaken the blade.

Are you sure you add it to the HEAVY end?

I use a teeter balancer (Dubro). I spray clear poly-u on the light blade. If the prop gently dips to one side, it's ok to balance. If it slams down hard on the table, return it to the hobby shop. Composite props are usually very well in balance, but check them anyway.

wood-week as heck, but sounds good
plastic- Strong as heck, but doesn't sound as good.

I use plastic because it seems to feel nicer on my finger when it gets cought [sm=lol.gif].
