There are three things you can use to increase the speed. Reduce the parasitic
drag. Reduce the incuded drag. Increase the HP.
The parasitic drag can be reduced by paying attention to detail with clean
lines, and fairings to clean up the airflow.
Induced drag is a function of the weight

Can someone explain to me why it is that there is such a gap in the top end
speed of KR's... ( HP aside )
There is a guy here in Longmont Co that has a KR... says he can do over 200
in it... ( not for me ).. but he can, running an O200. He says
If I can get 150mph out of my bird... I'll be more then happy!!

Speed in any plane is a function of excess thrust overcoming whatever drag is
present in a given plane. I am over simplifying but basically the less drag
the plane makes for a given horsepower the faster it flies. And drag reduction
has MORE effect than more hp. Several companies have do
Good Morning Jeff, I've included some websites that
elaborate on Collin's very good explanations of why
some planes are fast.
The "See How it Fly's" site is one of the best on the
web.
