The S-20 utilizes all-metal construction but keeps it simple by the extensive use of pop rivets. It features open-cockpit seating for one, low wings and conventional tail-wheel landing gear. The fuselage is of steel-tube truss construction with a light alloy skin. The constant-chord wings are also covered with the same light alloy skin.
First flight was made on March 9, 1972 by N106AB. S-21 was the designation for plan-built aircraft by home-builders.

single-seat military versions UL
ultralight

Single engined high wing mono¬plane with conventional three axis control. Wing has swept back leading and trailing edges and tapering chord; no tail, canard wing. Pitch control by fully flying canard; yaw control by under wing rudders at half span; roll control by differential canard. Wing braced from below by struts; wing profile; 100% double surface. Undercarriage has three wheels in tricycle formation; no suspension on any wheels. Push right go right nosewheel steering. No brakes. Fuselage, totally enclosed. Engine mounted below wing driving pusher propeller.
The Vitality was first announced in mid 1982, using differential canard for roll control and under¬wing rudders at half span for yaw control. In August 1982 Flightlline magazine was told that three Vitalitys had been built and 36 ordered, that production would be concentrated on the two seat version, and that an all new three cylinder 1000 cc radial four stroke was being developed for the aircraft.
A few weeks later came the announcement that Luscombe Aircraft was to move into a new factory in November and that the company hoped to have an aircraft produced by the end of February 1983. These aircraft never materialised, however, as the company announced later in 1982 that it had shelved the design, at least until the UK microlight airworthiness regulations were finalised.
Although that happened in March 1983, the design rights of Vitality were for sale, along with three prototypes one two seater and two single seaters. The design was first conceived some 11 years before and dusted off in response to the microlight boom.

Produced designs for light recreational aircraft with rear mounted wings and engines, starting with Vitality of 1971, from which Valiant ultralight and Rattler single-seat military versions developed. Other types included Viper and Ranger, Super Ranger and Twin Ranger, latter three types later further developed by United Aerospace Technologies.
