The Hines aircraft is complete nonsense. 300 knots carrying 6 people on 300 some hp using ducted fans- not going to happen. Where do all these people using 300-350 hp V8s pull their fuel flow numbers from? 300hp, BSFC .40 (really generous)= 120 lbs./hr.= 20 gal./hr. yet they say 10. How? The fastest Reno Sport class racers (tiny 2 place, highly refined aircraft) take at least 350hp to do these speeds at these altitudes. These guys are going to do it on less hp with way more flat plate area AND with ducted fans which are nowhere near as efficient as propellers. 2000fpm climb on this hp, this weight with this cruise speed using fixed pitch fans- again, not going to happen. I'd be interested in seeing their drive system for the fans too.
