Lol....
I was fighting Pawz in his 38 in my K4. We start slowing down in a horizontal scissors... I yet again forget about the slats... SLINK!... next thing I know I am upside down, Pawz has all the advantage and I am soon in the silk. Flying a K4 through all speed ranges is pretty darn challenging.
Late edit: Try nearly 6k ROC. Come of the rw, accelerate to 250, pull the leading edge of the wing to the horizon and hold on...magnificent.
