Dick Smith, the owner of the C180 which was used in FAA STC certification flights, reported after his first flight with the VGs in place; "Simply Incredible! I was doing steep turns at 50 mph and without VGs I’d have precipitated an accelerated stall. I couldn’t believe how responsive the ailerons were at that speed. It‘s like a completely different airplane in the way it feels and handles. Stalls are much more placid and control response is there all the way".
