H.E. Broadsmith designed the Clipper as a two-seater; he employed the outer wings of the Monospar ST-4. Spartan Aircraft Limited built one example at their East Cowes works in 1932. The aeroplane was initially fitted with a 75-hp Pobjoy R motor. Registered G-ACEG it flew for the first time on 14 December 1932. After modification to undercarriage, cabin glazing and cowling, it received a Certificate of Airworthiness on 29 June 1933.

In 1933 the Clipper was raced in the King’s Cup Race.

In 1938, it was re-engined with a Pobjoy Niagara III of 90-hp, after which it was used as a company hack until 4 May 1942, when it was destroyed in an air raid on Cowes.

The 1937 Spartan 8W Zeus was an evolution of militarized Executive with larger engine and greenhouse cockpit. One was built for the USAAC analysis as an advance trainer, NC17612 c/n 8W-1. A small number were exported as light bomber.

Designed by James Ford in 1935, the 7X Executive (Standard Seven) prototype of the 7 series (X/NC13984] c/n 0) featured a small tail and long dorsal fin. First flying on 19 February 1935, it was reportedly delivered to Mexico.

A total of 34 were built in the US between December 1935 and March 1940. The first flew on 19 March 1935, powered by a 285hp Jacobs, but all production aircraft were powered by the Pratt & Whitney 985 Wasp Junior.

The Spartan 17W Executive (ATC 628) was comparable to the D17S in speed, weights and cabin size, and it was powered by the same reliable Pratt & Whit¬ney. It was well liked by pilots, and being an all metal, low wing monoplane, was of more modern design than the Beech. Despite one less wing, however, it was no faster. The Executive never really had a chance to compete, though. Spartan was expecting to get a Government contract for a biplane trainer and in 1940 stopped production of the Executive to de¬vote all its facilities to that purpose. The con¬tract never came, and only 34 Exec¬utives were ever built, selling from $23,500.

One Spartan Executive 4/5-seat all-metal monoplane of 1936 was converted in 1938 to Zeus 2-seat military type as the 7W-F NX17605=42-68361 c/n 10 for military acceptance tests. Two guns were mounted in the nose and one in an open station aft, plus wing racks for ten 25lb bombs. It was later converted back to 7W.

The 7W-P Executive of 1936 (ATC 646) was a three-place customized 7W (NX13986 c/n P-1) first flown on 14 September 1936. Fitted with a 400hp P&W Wasp, it was exported to China.

Sixteen were conscripted by AAF during WW2 as UC-71 (42-38265 to 38269, 42-38367 to 38369, 42-38287 to 38288, 42-43846, 42-57514 to 57515, 42-68361, and 42-78037), of which the first 11 were impressed, all but 2 returned to civil use.

YI-SOF c/n 7W-19 was a $30,000 customized job in 1939 for King Ghazi of Iraq (including a regal throne) as Eagle of Iraq, in turn went to RAF in 1940.

By 1931 Spartan was producing low-wing side-by-side 2-seaters, further developed as C2-60. Designed by Willis Brown and selling for $2,245, the prototype NC11000 was under ATC 2-370.

Sixteen C2-60 were built ATC 427; NC11000, NC11015 and NC11016, NC11021 to 11023, and NC11900 to NC11909.

Two, NC992N and NC993N (ATC 2-408), were built as C2-165 instrument trainers with 165hp Wright J-5 engines and hooded cockpits for the Spartan School of Aeronautics.
