Design and development

The Dynamic is a cable-braced, king post-equipped hang glider-style wing designed as a touring wing for two-place trikes. It comes in three sizes.[1]

All members of the series are made from bolted-together aluminum tubing, with its 84% double surface wing covered in Dacron sailcloth. The wing's crosstube is of a floating design and all models have a nose angle of 125° and use an "A" frame weight-shift control bar. It is manufactured by DTA's subcontractor, La société Ellipse.[1]
