The test flight included basic stability and control tests in the cruise and landing configurations, the latter of which with flaps and skis extended. Speeds were limited to 80 knots and the SkiGull remained below 8,000 feet. Smith reported that the airplane flew straight with his hands off the controls. He also reported the speed and maneuvering stability as excellent. Lowering the skis and flaps resulted in no trim change and the stall speed appeared slower than that of the Piper Cub chase plane, Rutan said. However, he described this early evaluation of the airplane's stall characteristics as unacceptable, with no buffet and a roll drop-off to the right.
