Due to the strength of the carbon fiber spar caps, it turns out there's no need for struts. An 80 mm diameter, 2mm thick carbon tube above the pilot's head transmits all of the forces from the wing. 

Note also the electric propulsion is swapped for a 3W 275 two-cylinder 2 stroke because it's much lighter & also because the best electric options were all multi-motor (we even looked into a 6 motor system, 3 pods per wing) and it's not clear whether an ultralight is legal in France with multiple motors.  

Inspiration for the wing is from two sources: Colomban Cri Cri for the high lift profile, and Hurel Dubois for the high aspect ratio on a normal aircraft (not a glider and not high altitude like the U2).
