There’s a good reason why most airplanes look and behave alike: because it works. Technology choices like flying wings (not used here) or twisting wings (used here) are a “code smell” to my computer programmer nose. To me, nothing is sexier than good reliable technology that works. Smart investors will know that. The other ones will do you a favor by staying away.
The use of batteries to maintain altitude at night is a big concern. Batteries are heavy and will dramatically cut down on the usable payload. They need to be maintained warm (but not too warm!), which is a challenge at the low ambient temperatures the aircraft will experience while flying.
Most airplane accidents happen during take-off and landing. Please do not shortchange these phases of flight, and good luck.
