I like the planform. A little retro, a little contemporary - plus you
gotta have forward sweep unless you want the back seater to sit on the
spar. The Duo planform is similar, with the tips swept back. The Arcus
seems a bit more radical in the sweep changes, but that could just be
due to a narrower chord, which it appears to have.

Agreed, although I'm not sure I find it aesthetically pleasing (says
the man with a Russia AC-4 for sale!)... I'm betting the change in
wing-sweep on the outboard sections is to reduce twist loads and
improve the behavior/control-authority at the stall - but that's just
a guess from an amateur aerodynamics enthusiast. :-P Also, I'm
betting it would be weird to try to fit winglets onto a tip that is
swept forward.

Very cool, though! The future is now...
