Kyosho GeeBee Engine/prop?
I'm use to flying fast planes, and although I haven't thrown a radar on the Gee Bee, I fully believe its doing 100+ mph.
I'll have to check it out, as soon as I get the landing gear blocks fixed, both of mine have come loose. Its a bear because I siliconed the belly pan on, and the gear legs are under that. I think I can operate on the top of the wing, and it should still be covered by the wide fuze.
