I wonder why the rotors are positioned so low. Should a propeller get fractured, the splinters would hit the pilot's chest and neck.
OTOH putting the propellers above would change the shape and thus the aesthetics seriously.

2) There are classes where you're allowed less in exchange for easier certification. If the craft isn't operated commercially and doesn't need to leave national airspace, certification is typically far easier (at least for anything not heavier than a medium SUV).
