constructed of wood with sharply-tapered wings and fabric-covered control surfaces. An enclosed cabin with one seat was provided so the Queen Wasp could be flown manually with the radio control system turned off. The radio control system was complex with a number of backup safety devices to ensure radio and battery operation was uninterrupted. A trailing receiver aerial was winched out after takeoff and served as an automatic landing device which was activated when the trailing aerial weight hit the runway. The sensitivity of the system in turbulent weather meant that an alternative landing signal was used to initiate a landing procedure."Airspeed AS.30 Queen Wasp" 1978, p. 40. The landplane first flew on 11 June 1937, and the floatplane on 19 October 1937. The floatplane was successfully catapulted from HMS ''Pegasus'' in November 1937.

Operational history

In flight tests, the aircraft was found to be underpowered and water handling difficulties necessitated a redesign of the floats by their manufacturer,
