This was when Bryant woke up in the night with his brainwave – springing out of bed to write it all down, lest he forgot. The idea was to remove the fuselage, essentially have a flying wing, and put a rotor on each corner, each falling outside the boundaries of the airframe. "When I started to research flying wings, I realised it was the most stable aircraft architecture going," said Bryant.

An obvious comparison, for someone who knows their aircraft, is the Boeing V-22 Osprey, whose rotors can be oriented vertically for take-off and horizontally to provide forward thrust in flight.

Fly-by-Wire-Drohne:

Bryant, believing his aircraft could take the positives and remove the negatives for each drone type, took his idea to DLR, the German aerospace research centre. He commented: "The Germans are very, very clever at small wing design – high lift, low drag wing design. It is an advanced aerofoil shape that means we can create high lift at low speed. So if, for example, we are flying at 10 knots, we can reduce the amount of power by 50%. If we fly at 15 knots, it is a 75% power reduction, just because the aerofoil is providing the lift." It also means the Flying Wing can hover into the wind while using very little energy

Bryant continued: "A key feature is that it is a fly-by-wire aircraft. Unlike many other small light unmanned aircraft, we have decoupled the command input from the actual control of the aircraft.
