Stinson Stinson SM-1 Detroiter



The first design from the Detroit-based Stinson Aircraft Syndicate was the Stinson SB-1 Detroiter, a four-seat cabin biplane with novel features such as cabin heating, individual wheel brakes and electric starter for the nose-mounted 220 hp (164 kW) Wright J-5 Whirlwind engine.
This aircraft was soon developed into the six-seat Stinson SM-1D Detroiter, a braced high-wing monoplane version which made its first flight on 25 January 1926. The aircraft was soon a success and it enabled Stinson to get $150,000 in public capital to incorporate the Stinson Aircraft Corporation on 4 May 1926.
Seventy-five of the Wright J-5-powered versions were built, followed by 30 Wright J-6-powered aircraft. From 1928, SM-1 aircraft were used on scheduled services by Paul Braniff's Braniff Air Lines and by Northwest Airways.
Three of this model were bought by Honduran Air Force in 1933. The China National Aviation Corporation, China Airways Federal, and Shanghai-Chengtu Airways operated the Detroiter in the 1920s–30s, and in Peru they were operated by Faucett and the Peruvian Air Force.
Stinson SM-1F
In 1930 a SM-1FS with a crew of three reached Bermuda from New York City, the first flight ever to the islands. Getting there the aircraft had to land twice, once because of darkness and later after running out of fuel. With a wing strut damaged, it was shipped back to New York.
A Detroiter version of the Stinson Junior powered with a Packard diesel engine, held the world record for endurance without refuelling.
In all over 100 were built, and in 1928 Stinson developed the smaller SM-2 Junior model to appeal to private owners.
