Thanks for all the SO, prop, and motor help! On the rubber issue: you say the rubber loses power after the first wind or two. Does it recover, or does that mean you need to use new rubber for any serious competition? If it doesn't recover, I suppose the rubber gets weaker and weaker with every use, until it eventually breaks.
If less than full winds are used, does the rubber still lose power? Does the change happen a lot slower? I know some things don't fatigue unless a certain stress level is exceeded.
Mike, I haven't met the student yet, so have no idea whether a trip to Racine is possible. I've only been in email contact with his mother so far. I will explore that option.
