Design and development.
The base model Profi wing is a cable-braced, king post-equipped hang glider-style wing for two-place trikes, while the Profi TL is a "topless" design, lacking the king post and using streamlined lower lift struts instead of wires. The topless design lowers the overall height of the wing and allows storage in lower-roofed hangars. A carbon fibre leading edge insert is optional, while winglets are standard on the TL model.
The wing is made from bolted-together aluminum tubing, with its double surface wing covered in Dacron sailcloth. Its span wing has an area of , a nose angle of 128° and uses an "A" frame weight-shift control bar. An electro-mechanical trim is optional.
