I have owned experimental aircraft for many years, and have NEVER suffered the lunacy of getting in an experimental helicopter. Too many variables there.
Okay, one time I got in a Rotorway (with the Evinrude outboard engine turning 6500rpm!)
Never left ground effect. No way I was going to experience two-stroke engine seizure in an aircraft!
Ever rode a 125 Bultaco wide open for long?
