If you have additional information (ex: specificity of piloting, various characteristics...) on the hang glider Exulans by University Of Pretoria, you can supplement his card by adding your comment or write to us :
Apparently the Exulans (named after the scientific name for albatros)used some wingtip pivot shift for pitch control, in combination with elevons to overcome the inherent ineffeceincy of elevons for pitch alone. The control mechanism and hinges must have been complex. Far as I know it's the only wing to successfully try it. Seems it was tested successfuly but no commercial version has yet been released.

I worked on this aircraft as an undergrad. Remarkably simple, lightweight design and is a hang glider with sail-plane performance.
As far as I know, the designer Joachim Huyssens and his team are working on a second prototype.
Yes, a second prototype is being built. I have been working on it since 2004 and now I am working on the design and propulsion of the 1/4 scale model. Very interesting aircraft and I hope to see it fly soon! If solar powered studies prove that it is viable Diomedes Innovations would like to fly around the world in the Exulans in order to raise funds. We would like to approach any Company's interested in assisting.
The 1/4 Scale Model has been manufactured and flown.
