Pleased with the days work... the 18-inch frame seen fitted here with 36-inch propellers, ample rule for a bit of armour around my bod and that's 8 feet 5 inches across the tips (or an inch inside the GoFly guidelines).
I actually still like the props mounted up top too, not so much because the motors need the cooling (but then every little helps when you hit TOGA thrust) but because you can scope the tips altogether more easily.
An advantage of eVTOLs over helis is the fact you can get up close and personal, and I figure with white tips and LEDs you can place those propellers within a smidgeon of obstacles.
