I'm not quite clicking with the design. I'd figure you'd need at least the wing span of an ultralight to get that off the ground, plus a bit more for the weight of its fully paneled body. I'm just not seeing how you fit an engine and enough fuel for a reasonable flight in that package. The doubled wings buy you a little span, but it just doesn't seem to have enough surface area.

It seems it'll have a theoretical range of 70km. It's more a toy than a real plane (like JetSky vs. real boats).

Probably fun though!

I figure a rigid wing can have a more efficient aerofoil than an ultralight would do, plus these seem to go a fair bit faster.
