We need to start adopting some of this stuff for rc speed attempts...
I was surprised about the part with the wheel openings being half the aerodynamic drag of the whole thing... I should note the boat tails on a bunch of those things.
And the speeds those guys are getting, wow. If they can move ~250 pounds to over 75mph, we have some work to do with what, 3-4 horsepower moving less then 10 pound machines?
