It was built to test methods of wing construction that would later be suitable for plastic skinning. ==Development== The Knight was a conventional looking low-wing monoplane, with a fixed tailwheel landing gear, the main legs housed in trouser fairings and powered by a nose-mounted 90 hp (67 kW) [Blackburn Cirrus Minor](/source/Blackburn_Cirrus_Minor) piston engine. It had an enclosed cabin with side-by-side seating for two. It had an unusual wing construction which used four spars and interspars instead of ribs.{{cite magazine | title=Towards Thermoplastics: An Interesting Form of Wing Construction |magazine=[Flight](/source/Flight_International) | page=100 | url=http://www.flightglobal.com/pdfarchive/view/1937/1937%20-%202056.html| date= 22 July 1937|volume=XXXII |issue=1491}} Though the wing was made of wood throughout, with a stressed plywood skin, the purpose of its novel construction was to explore methods suitable for later use with plastic materials.{{Harvnb|Grey|1972|pages=35c-36c}} The wing was tested at the [Royal Aircraft Establishment](/source/Royal_Aircraft_Establishment) Farnborough and the root fittings but not the wing failed at 12.3 times the weight of the aircraft, well beyond the target load factor of 9.
