Looking at the computer rendering of the Eviation above, the thing that strikes me is that it looks exceptionally lightweight, judging by the doors and stairs, and the landing gear. I know composites can be very strong, this just looks to me like it's pushing the limits.
Of course light weight is an advantage for E-power, but I wonder about compromise with safety in hard landings or actual crashes. Maybe the real thing would be less delicate than the rendering looks at first glance, if it ever makes it into production.
