Quad-copter or octa-copter drones as well as fixed wings drones are common, but a hybrid drone is still a rare bird in the sky.

Recently, TU Delft (with help from Parrot) presented a much more exquisite arrangement. Its new DelftAcopter drone combines features of both a fixed-wing flying machine and a helicopter utilizing only one propeller.

Its tailless biplane form gives it the ability to take off and float vertically, then quickly move forward (up to 62 mph/ 99.7 kph).

The drone is totally self-governing on account of GPS, movement sensors and PC vision.

The model has a flying range of up to 37 miles (60 km) and it can keep running for 60 minutes on its electric engine.

The manufacturer has already planned to use the drone for medical supply in remote areas. In addition, the drones may serve for other delivery purposes as well as for search and rescue (SAR) missions.
