>Perhaps you can explain the vortex generator to me.
Vortex generators prevent separation of the airflow from the wing surface
by creating turbulent flow. It will help in reducing the effective stall
speed for most aircraft because they are placed in the area in front of
ailerons and flaps to guarantee that the airflow will not separate prior to
hitting those surfaces. The stall becomes more recoverable. With the KR2's
long aileron and a wing designed to stall at the tips first, they only
create more drag without impacting stall speeds. {You will recognize the
loss of lift on a KR2 long before you will be thrown into a spin.} Anything
that creates turbulent flow creates drag (bad, bad, bad when you want to go
fast with a small engine).
