Built in 1976 at Yeovil, Somerset as a remotely piloted observation helicopter, the "Wisp" was powered by two Korba 2-stroke 2-cylinder piston engines. Following the development success of the "Mote", Westland began construction in 1976 of a larger version of a airborne surveillance system that could send live TV and infra-red pictures to a portable control station day or night.

The first of three prototypes was completed in August 1976 with a first flight on 2nd December 1976. Trials were carried out in 1977 but the payload was considered limited and the project had already been succeeded by the larger "Wideye".
