Chris Harris from Rotec told me that they ground about 1 lb from the
sides of the rotors in the race cars. The benefit is in faster response
of the engine in the low end of the RPM. I don't think that will benefit
aircraft application. Also it costs few hundred dollars of machine work.
Bulent

No problem to write a program for doing this, and would only take less than
an hour per rotor. Could do them for about $50ea. but seems hardly worth
the effort for an aircraft application. Now if it were a 4
rotor....................

Well now if you have a constant speed prop you can run the engine at 10,000 RPM
for takeoff and vertical climb :-) Should get about 350 HP out of a NA
 230 pound engine.
