I think we need to clarify our terms in our discussion on "control sensitivity" and "stability" in the flight characteristics of the KR2.
I don't think anyone can argue that the controls in the KR are extremely light and take very little movement to effect a change in flight attitude. Having said that, the KR is extremely easy and fun to fly. You just have to take that in to account and fly accordingly. You can't be "heavy handed" on the controls like in a Cessna, Piper, etc. Stability is a different characteristic entirely. When flying my KR today, I got it trimmed up in cruise to fly hands off. If I bump the stick at that point to knock it off it's stable condition it diverges from trimmed flight at an ever increasing rate. That goes for pitch or roll in my KR. It WILL NOT returned to trimmed flight without the pilot providing control input. If your KR flies differently, I'd like to see it demonstrated. I seem to recall reading that to be certified ( Cessna, Piper, etc.) the aircraft must return to trimmed flight (pitch?) within a certain period of time or a certain number of oscillations. My KR would not meet those requirements. It is NOT inherently stable. The flight characteristics of the KR should not scare anyone away from flying one. I have more fun flying my KR than anything else I've ever flown. Yes, the controls on my KR are sensitive but it is easy to fly. But, it will not fly itself. An aft CG will make the KR, with its very light and, yes sensitive controls, maybe even more difficult to fly than some other aircraft but it's up to the builder and pilot to keep the CG in the proper location. Build it right and fly it right and it is an AWESOME little airplane. Larry Flesner
