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).
