Gary, I've been following this conversation with interest. In recent day's I
re-read Harry Ribblets book and have to wonder if maybe he couldn't provide
you ES/IV drivers with a cuff that would do the trick. [ For those of you whom
aren't aware, Mr. Ribblet has done some good work on taming the likes of the
Bd-5 as well as other aircraft by re-profiling their airfoils, apparently with
some success] I've flown several aircraft w/ Stall cuffs [i.e.: Horton kit on
a Cardinal] and its amazing the difference in stall speeds as well as
behavior, for a small penalty in cruise speed. Anyone else have an opinion of
Mr. Ribblets work? I'm sure a cuff could be made that could be easily attached
and faired in, easier than some of the cuffs used on alum. a/c as you'd just
bond it on!
My 2 cents.

235/320 55% [and holding]
reattach easily. A drooped cuff seems to be the accepted cure for this
problem, as done by both Lancair and Cirrus. During my wing construction I
was tempted to take a mold off the leading edge and the slide it forward on
the upper surface to create my own cuff design, but then I figure I would be
going to far into the "experimental" realm, so I didn't.
