These discussions on the right prop so far have been somewhat interesting but yet void of any scientific research. But that is what we are in this for, right? We are building experimental birds, we should therefore be experimenting, learning, etc. Since the price of a propeller is so expensive. I wonder if some of us could get together and design some tests that we would perform that could actually give us this information. We may not be able to benefit directly from it as we have already put $$ down on a prop, but, it would help future builders. Heck, it may even inspire someone to build a better prop... I see some test plans designed and instrumentation requirements figured out. Then a few legacies get together over the period of a week or so, install instrumentation, swapping props, flying and collecting data. We could have these tests reviewed by folks and make sure we have something that would: 1. Account for discrepancies in engine performance. 2. Account for differences in atmospheric conditions. 3. Really give us information that would be valuable in selecting the best propeller (if there is such a thing). I think it would be a very interesting and fun project...and educational to boot.
