RE: Why aren't there more float plane designs for .09 engines?
KM,
I saw your video on your little "Twinkle." It flies great and the handling on the water is superb.
Did you ever think of having taxiing races?
My retention pond might be a little less than I need for something as fast as your "Twinkle." An .061 Norvel version should really honk. I think larger version with a mild .09 might provide useful power for slower flying.
