Dick,

I certainly don't mind at all - very nice rendering!! This is a great representation of the profile I'm talking about! Nice work!

If this profile were to be built into a structure for wind tunnel testing, and from that perspective if I were to suggest any changes to your silhouette of my MH32/KF3P profile, it would be to reduce the depth of the secondary step which is located quite closely in front of the aileron hinge line. [I'm flying a ~3mm primary step, and only a 2mm secondary step on a wing with an average 9" chord.]

I'm theorizing that the shallow depth secondary step contributes to the clean and precise aileron response with minimum drag when control surfaces are deflected substantially; earlier reports indicate that deeper steps close to the aileron hinge line result in excess turbulence and substantially reduced response to substantial aileron deflection.

Merry Christmas to ALL!!!
