ABSTRACT:
A method of operating a multi-element self-trimming sailset to assist deflection of the trailing element of the main thrust wing to either side of the leading element. The sailset is first rotated to reduce the moment of wind on the flap opposing deflection, the flap is deflected, and then the sailset rotated to its operating angle of attack. Rotation of the sailset is achieved by a tail vane.
