Well, I waited a couple of days to see whether anyone would respond to Walt
Dodson's post recommending that someone develop drooping ailerons for the
IV-x. I'm surprised that one of our resident aerodynamicists didn't pick up
on this one.

I'm not so sure that's such a good idea, considering that presently, with
the flaps deployed, the outer portion of the wing (with the ailerons in
trail) remains at an effective lower angle of attack than the inboard
section where the flaps are located. This may very well be a powerful safety
feature of the wing (perhaps inadvertently, perhaps not - I haven't heard
anyone speak of it before) that keeps the tips below the stall angle of
attack and flying, when slow and heavy - like on take off or in the pattern
for landing.

Like my guru (from whom I really learned my trade - years spent in college
aside) always maintained, when attempting to improve on a design, "You can
never do just one thing - something else will always be affected, usually
adversely and and unexpectedly".

Since your butt will be in the airplane when testing your "just one thing"
you just might, as a B-1 test pilot friend once put it, "Be the proud owner
of some very interesting information that will do you absolutely no good
after the crash".

On the other hand, aircraft design is never improved unless some brave soul
is willing to put his nugies on the line - and in this case, judging from
the history of the IV getting away from even good pilots - it'll require
some big ones.

OK. Flame suit on.
