Oh yeah, props. I bought a bunch of 11x6 wood and nylon props. If I place a wood prop on a pen, one side droops down, so it's off balance a bit. Do I just sand the heavier side a bit until it evens out? I know vibes from unbalanced props is a bad thing.
NEVER remove material as it may weaken the blade. You can spray clear varnish on the back of the lighter blade to make it heavier. Do this in thin coats.
On composite blades you can add paint to both tips to make them easier to see when running. Add more to the lighter blade.
