Quadcopters are great at hovering, but don’t have long range. Fixed-wing aircraft can travel long distances quickly, but don’t like to stay in one place above the ground.
Krossblade’s SkyProwler solves both of those problems. The hybrid aircraft is a remote controlled quadcopter with wings, or a plane with six rotors, capable of vertical takeoff and landing (VTOL).
