The Beechcraft Staggerwing is a Biplane with, unusually, a backward stagger (the lower wing is further forward than the upper wing). DEVELOPMENT At the height of the Great Depression , aircraft executive Walter H. Beech and airplane designer T.A. “Ted” Wells joined forces to collaborate on a project many considered foolhardy — a large, powerful, and fast biplane built specifically for the business executive. The Beech Model 17, popularly known as the “Staggerwing” was first flown on November 4 , 1932 , setting the standard for private passenger airplanes for many years to come. It was considered, during its time, to be the premier executive aircraft flying, much as the Gulfstream executive jets are considered in contemporary times. Initial Design at the beginning of Staggerwing production (note the fixed landing gear).]] The Model 17's unusual behind the lower — and unique shape resulted in a design that maximized the pilot's visibility while minimizing the aircraft's tendency to Stall . The fabric-covered Fuselage was Faired with wood Former s and Stringers placed over a welded, steel tube frame. The construction of the plane was complex and took many manhours to complete. The Staggerwing's use of retractable Conventional Landing Gear , uncommon at that time, combined with Streamlining , reducing the weight of the materials, and its use of powerful Radial Engines ranging from 225 to 710 Horsepower (168 to 529 Kilowatts ) produced an aircraft with impressive performance. The Model 17 could achieve a top speed of 201 Miles Per Hour (323 Kilometers Per Hour ), which made it faster than most Military Aircraft of the era. It had a low landing speed of just 45 miles per hour (72 kilometers per hour), and it was able to climb at 1,600 feet per minute (488 meters per minute) to a maximum altitude of 21,500 Feet (6,553 Meters ). Sales started slowly at first; the first Staggerwings' high price tag (between US$ 14,000 and US$ 17,000, depending on the size of the engine) scared off potential buyers in an already depressed market for civil aircraft. Only 18 Model 17s were sold during 1933 , the first year of production, but sales steadily increased. Each Staggerwing was custom-built by hand. The luxurious cabin, trimmed in Leather and Mohair , could hold up to five passengers. Eventually, the Staggerwing captured a substantial share of the passenger aircraft market. By the start of World War II, more than 424 Model 17s had been sold. Air Racing The Staggerwing's speed also made it the darling of the air racers of the 1930s . An early version of Model 17 won the 1933 Texaco Trophy Race. In 1935 , a British Diplomat , Capt. H.L. Farquhar, successfully flew Around The World in a Model B17R, traveling 21,332 Mile s (34,331 Kilometer s) from New York to London , by way of Siberia , Southeast Asia , the Middle East , North Africa and back across Europe . Aviatricies Louise Thaden and Blanche Noyes won the 1936 Bendix Trophy Race in a Model C17R Staggerwing. Thaden also won the Harmon Trophy for her achievement. Aviatrix Jackie Cochran set a women's speed record of 203.9 mph, established an altitude record of over 30,000 feet (9.144 meters), and finished third in the 1937 Bendix Trophy Race, all while flying a special Model D17W Staggerwing. The aircraft made an impressive showing in the 1938 Bendix race as well. Design Refinement Beech, meanwhile, embarked upon a major redesign of the aircraft, to be known officially as the ''Model D17 Staggerwing''. The D17 featured a lengthened Fuselage that improved the aircraft's Landing characteristics by increasing the leverage generated by the Elevator . Aileron s were relocated on the upper Wing s, eliminating any interference with the air flow over the Flaps . Braking was improved by the introduction of a foot-operated brake that was synchronized with the Rudder pedals. All of these modifications enhanced the Staggerwing's performance, which would soon be put to the test under wartime conditions. World War II As World War II loomed on the horizon, a number of Model B17L were pressed into service by the forces of the Second Spanish Republic as Bombers during the Spanish Civil War . China ordered a number of Staggerwings to use as Ambulance planes in its fight against Imperial Japan . Finland had one B17L as a liasion aircraft between 1940-1945. On October 2 , 1941 , Beech shipped a special Camouflaged D17S to Prince Bernhard Of Lippe , who was in exile in London after the Nazi invasion of The Netherlands . He used it for refugee work in and around London. The Beech UC-43 Traveler was a slightly modified version of the Staggerwing. In late 1938 , three Model D17S were purchased for evaluation by the United States Army Air Corps for possible use as a light Liaison Aircraft . These were designated '''YC-43'''. After a short Flight Test program, the YC-43s were sent to Europe to serve as liaison aircraft with the Air Attaché s in London , Paris and Rome . Early in ) additional "Staggerwings" from private owners including 118 more for the USAAF plus others for the United States Navy . In Navy service the planes were designated as GB-1 and '''GB-2'''. The British Royal Air Force also received 106 “Traveller Mk.I” (the name is correct with the anglicized double "l") through the Lend-Lease arrangement to fill its own critical need for Light Personnel Transports . The production UC-43 differed in minor details from the service test YC-43. Two distinguishing external features of the UC-43 are the circular ADF Antenna mounted between the main landing gear and Landing Lights near the lower Wingtip s. They were all powered by the 450 Horsepower (336 Kilowatt ) Pratt & Whitney R-985 engine. Post war After the war's end, Beech immediately converted its manufacturing capabilities back to the production of Civil Aircraft with one final version of the Staggerwing, the Model G17S. 16 of the powerful aircraft were built and sold at a price of US$ 29,000 apiece. One D17S was sold to Finland from Norway in 1949 and it was used for Finnish Air Force between 1950-1958. The lightweight V-tail Beechcraft Bonanza , a high-powered four-passenger luxury aircraft, soon replaced the venerable Staggerwing in the Beech product line, at about one-third the price. The Bonanza was a much smaller aircraft with much less horsepower (about 200 verses at least double that in the Staggerwing), but carried four people with almost exactly the same speed as the Staggerwing. The final Staggerwing was sold in 1948 ; it left the factory in 1949 , the last of 785 aircraft. Legacy In March of 2003, Plane & Pilot Magazine named the Staggerwing one of its' Top Ten All-Time Favorite aircraft {Link without Title} . VARIANTS AND DESIGN STAGES
:By 1934 , Beechcraft had designed and built four models. They were the 17R (420 hp Wright engine); the '''A17F''' (690 hp Wright engine); the '''A17FS''' (710 hp Wright engine); and the '''B17L''' (225 hp Jacobs engine). All were Fixed Gear models with the exception of the '''B17L''', which had a Pneumatically retractable Undercarriage . Of the three models, the '''B17L''' proved best suited to meet the market demands, and became the first production model.
