The GAW-1 airfoil is a spin off from the first Supercritical airfoil

.This is absolutely nuts, comparing the flight of a golf ball to an
airplane is like comparing the weight of a bowling ball to a ballon. The
airplane with a laminar flow airfoil on the wing is the lowest drag you
can get and is the fastests, but to get laminar flow the surface must be
very smooth
You can put a stall strip on the wing to make it stall first look at the
inboard leading edge of a Beech Bonanza and the Tiger and Traveler of
American Aviation Co. Easy quick fix.

More lift may not mean more drag, the increased skin friction drag will
be off set by the reduced induced drag.

Read you Dec 11, 2005 note on hershey bar wings, why would you put a
hershey bar wing on anything, especially a LSA airplane? That would put
the increased lift out at the wing tip where you don't want it. I have
looked at redesigning the KR-2, of course it would not be a KR-2 anymore,
but it would
KR-1 planes just give an idea as to how it should be built, I would just
use the new airfoils for the stub wings and the outboard wings, its a
powered sailplane and needs the laminar flow airfoils.

I don't think it is a lot of grief, thats all I did for thirty years is
redesign aircraft to make them fly at transonic speeds or increase the
drag rise Mach number from speeds like 0.82 to as high as 0.98. The
KR-1B is a good idea, but single place and the Sonex has all those rivit

You are correct, props are airfoils and the airfoil one uses can have a
large effect on the performance. A supercritical airfoil can increase
the drag rise Mach number as much as 15 percent which means a larger
diameter prop can be used at the same RPM if the outside20 percent used a

No question that William is the expert on corvair engines and that Mark
is the KR expert but there are other experts on the list thst have forgot
more than someone has learned from building and been flying a KR-2 for
twenty years. Marks work on bringing the new airfoil subject is a good
point and
Stability is a function of the tail volume (area of the tail X the moment
arm), so you can increase this by strecheing the fuselage or by
increasing the area of the horizontal tail.
