I think I have spotted the fatal flaw in his design.....

The pack is back mounted, with the exhaust directing thrust to the ground.

So, OK for vertical flight - well, sort of in theory giving the benefit of the doubt right..... soooooo


Forward flight, vector exahust away from body, tipping forwards a la helicopter, and forward flight achieved. Yeah?, with me?.

To come to a halt........

Vector nozzles forward.

Hmmm and burn legs off whilst halting, hence the extra flight time as body mass is reduced.[:@]

Do we take our hat off to the guy who sold the turbines or do we lambast him for poor practices!
