I know what everyone is thinking... Why?
Rather than argue the question, I am publishing the flight test results of installing StolSpeed VGs on my HR-II.
Summary: StolSpeed Vortex Generators were installed on a Harmon Rocket II (C-GVRL). Flight test results showed improved stall behavior and a 3 KIAS reduction in full-flap (VS0) stall speed; with a 1.7 KTAS reduction at fast cruise speed. Little reduction in clean stall speed or partial flaps (15 degree extension) stall speed was indicated.

Cheers.
