Eish - That nose wheel....

looks interesting. Can't make it. Wonder if there will be website? Any idea if it flown?

Yes, Joachim Huyssens. The development started off with the Exulans wing (scientific name for Gull). It comes down to the unique concept where you create a "swept back" wing platform of the outer leading edge. I remember the test flight of the concept in early 1990's. Unfortunately not succesfull due to VNE and overstressing after balloon drop.

The concept is very sensible. On a trike, or delta wing, your outer leading edges and that part of the wing does relatively little to create lift. The tips play more a role on take-off and landing. By being able to sweep the tips back in flight, they become more productive with less drag.

I will attend. Definitely !

RV4ker, no, it is in proto-type stage.

Google "exulans". Info very scarse (secretive). Tells me they are onto something. Lots of patent rights taken and pending I believe. Mind you, this development started 20 years ago at the University Pta as part of a masters for Joachim.

I also remember the balloon drop and the subsequent parachute landing Have some photos somewhere. I also have a video of the flight and some other material.

Will make a plan to attend....
