Bill: I can not address this with respect to KR aircraft but do have knowledge of an elevator stall problem in the early units of a certified craft that led to ADs. The early Cessna Cardinals(177s) with the Laminair flow wing had such a problem That crafy has a "Flying Tail" and is a high wing. Cessna cured that problem by adding LE slots to the elevator. I do not know whether it help or not but perhaps some examination of the elevator stall problem assciated with the Cardinal problem may serve as a basis for understandin of elevator stall problems cause and cure. Perhaps a direct inquiry of Deihl himself will shed some light.
Just a suggestion as it sounds way to importent to let slide.
