way back in the late 1980s when I first got involved with KR and bought a few parts, I'd befriended a kr-1 builder and flyer who operated his for 20 years in Ohio. in fact I believe he is memorialized on Mark's web site.
anyway he described repainting his kr1 which could reach well over 200 mph easily in a shallow dive he said, and after the repaint he had an incident of aileron flutter. he was an understated kind of guy. but he talked about not being able to see the instruments, they were just a blur, and having the presence of mind to neutralize the controls and simply remove the power instantly and let the energy bleed off. he found no damage but it was a lesson learned.
