Hi Ed.
Nice of you to respond on Christmas. I'm building a 4 ft Hugh machine. I'm building it to his specs.
A freind is carving the blades for it as per Hughs instructions. I'm setting up a small wind tunnel test and wish to compair preformance of several styles of 4 ft blades.
I will also be evaluateing several diferant styles of stators. I purchased his book and the magnets from our hosts. I've collected all the materials, now just to find the time for assembly and testing.
I belive Hugh says his recemended carved wood blade has a TSR of 5. I think TSR of 5 is to have an earlyer startup then a TSR of 6?
I hope to do these test over the next few months?
Thanks again for your help and have a very nice Christmas.
