* 15min flight time * I'd estimate 5 miles range * if you roll it into the water and any part of the battery is exposed you'll be electrocuted and likely drown.

Fixed wing is the only way to go for efficiency and I can't imagine anything other that a hybrid having more than 45minutes flight time @ <40knots. It's deffo possible to make a high lift, low speed fixed wing that has a short takeoff/landing requirement. There are elec ultralights that do this today. This whole obsession with elec/'coter design baffles me - even with the most optimistic math assumptions it is a terrible product.
