Airfoil
The airfoil is similar to the Neme-Q, Bird of Prey, and Vortex.
When Michael sent me the airfoil about a year ago, I compared it to my Neme-Q and Vortex. It was very close, but slightly different. I'm sure Michaels would be very close in speed to the rest, probably hard to tell the difference.
They are all very close, and seem to be about the fastest thing going these days. It would be nice to have the time to make about 10 variants of this airfoil and have it objectively tested. Unfortunately most of us just don't have the time to do that.
My thoughts on the wing tips is this. I will sand the wood ones down, and see how the plane flies. If I like it, I will make my mold off of the wingtips for future use.
I'm hoping to get a flight report from Bill soon. By the looks of our weather today, it may be a while before I get a chance to fly mine.
