Re: Kasper wings video
Hi Arup,
][/youtube]
My restored 1977 built BKB-1 flies nicely but too much elevon throw can stall the entire wing resulting in a snap roll and piano impersonation - loosing a lot of height before recovery. Turns on rudder and elevator are pleasant and trouble free across the entire speed range.
However the rudders are very vulnerable during transport and rigging.
Note the video shows both the BKB-1 and the later modified Kasper Wing.
Most of the performance and other aerodynamic wonders claimed for the design were not independently verified.

Oh I should have addezd that the vid is the maiden and the oscillations are experiments and retrimming. The model performed well on a small hill in very turbulent conditions.
