As far as aerodynamics and wind restitance I use to go out to the dry lake at El Mirage to watch the top speed racers, those guys would tell you anyone can run 125. MPH, a lot of cars can run 150 MPH, but to go from 150 MPH to 175 MPH reuquired either doubling the HP or reduce the aerodynamic drag

It is all relatitive on HP, drag and improvements, isn't it

I also know some guys that help several different Formula 1 air racers (tiny airframes and motors

) at the Reno air races, they really focused on drag reduction

Any and all gains are worth while
