Does anyone know if the wing tip (vertical winglets) add anything to the
rate of climb or anything else in the performance of a small plane like the
KR2?

I can't point to a specific reference for this "opinion", but I remember
reading that they do help at speeds over 400 mph, so for our plan

Aye Mark, are you in the mood for an aerodynamic debate? :-)
I thought winglets recovered waste energy derived from induced drag, that
is, the wing tip vortices. Is

Nope, not at all. I don't know diddly about aerodynamics, so it would be a
lopsided debate. I just threw out the only tidbit I remember about
winglets. I've seen various formulas for making them, and they hav

Hmmm. I wasn't aware that KRs had a problem with aileron control at low
speeds...

Most of what I find on the web regarding winglets has to do with sailplanes,
which are at the slow end of the speed spectrum. KRs operate at
considerably higher speeds, so I'd wonder if there's not a compromise
somewhere without actual testing on a KR. I might be talked into testing
that later o
