It would appear that I'm in the minority here, but....that's OK.

In 25 years of cutting my fingers with model airplane props, I have had or seen more vibration problems that could be directly attributed to good looking and poorly balanced/distorted spinners than I care to recall.

I guess it's all in what satisfies you.

Most of the cheap-o's are a little off to start with. As soon as you start chiseling material out to open it up to fit "X" prop...all bets are off. Sure...we're talking fractions of a gram. Consider a 1/2oz imbalance on a 40lb car tire will shake your teeth out at 55mph. What does a 1/4 gram do to a 1oz spinner at 12,000rpm?

You're radio will tell you. Sooner or later.

Shake on!
