I'm surprised by the struts supporting the wing; that saves weight (probably important here), but at the cost of drag. Wikipedia suggests a rule of thumb of 200mph being the break-even point for struts vs cantilever, and I would guess this plane is supposed to cruise faster than that. However, I didn't see the cruise speed listed anywhere; does someone know what they are targeting?

On another note, other than the struts, the design is reminiscent of the DHC Dash-7, a STOL airliner from the '60s that also used slower propellers (with gearing instead of an electric motor, of course) to reduce noise. That plane wasn't particularly fast either (240kts max speed).
