This very short take off version is designed for urban operations where runway space would be very limited. The UAV, made from composite materials, has a 2kg (4.4lb) payload capability, combined wing/rotor span of 2.4m, a dry weight of 5.5kg, a 12kg maximum take off weight, a 1.2kW engine and a flight speed of  15.5kt (28.8km/h).

Its development goal is an 80min autonomous flight capability.

The England-based FanWing was set up in 1999 to develop blade wing technologies.
