Thanks SpainCub for that graphic.
Are you guys thinking about the detrimental effect of all that stabilizer being dragged through the air at high AOA?
.....thus the recommendation to try a very large elevator and very small stab.
....ps......procceed carefully.
Also, the Keller Stabilizer with it 's ribbed-convex lower surface is a simple solution. A "quickie" test could be taped onto the bottom of a a stock stab so one could experience it without building new stabs.
PS. Finding a wing airfoil and flap arrangement that has LESS PITCHING MOMENT with the flaps deployed than our present Cub airfoil with slat and Keller flap would be another solution. I am sure there is one out there with a better cruise drag profile as well.
