Doyn Aircraft Inc
USA
This Wichita, Kansas, company, offering conversions to provide more power and performance to Cessna models 150,170,172,175, and Cardinal, was taken over by Air-Mod Engineering Company of Oklahoma City. The Cessna 170 conversions were known as the Doyn Dart I; the Dart II of the mid-1960s was a refined version of the Piper Apache. Beech Travelair conversions were also completed.
Doyle O-2 Oriole / O-3 Oriole
William Burke of the Vulcan Last Company backed the Wilson and Harvey Doyle plan to build a two-place, tandem, open-cockpit parasol sportplane and the Vulcan Aircraft Division began design work in a rented second floor room and construction in a former street car barn in Portsmouth.
The resulting Vulcan American Moth was a hit, but the relationship among the principles was deteriorating and the Doyle brothers left to start their own Doyle Aircraft Company in Baltimore. They produced fourteen Doyle Orioles which were similar to the Moth before bankruptcy ended the effort.
The prototype flew on 15 October 1928 with a yellow and black paint scheme and was priced at $2,975. Doyle Aero did not survive the Great Depression economy and ceased operations after a short production run. Harvey Doyle became an aeronautical engineer, and Wilson Doyle would become a professor of Political Science.
Seven of the O-2 Oriole and one O-3 Oriole were all built in 1928.
The last surviving O-2 serial number A-5 (NX9531) was restored in 1984 after being in storage since 1934 and identified by its designer Harvey Doyle.
Doyle Aero Corp
Two brothers named Wilson and Harvey Doyle were 1925 graduates of Harvard and Yale respectively and moved to Portsmouth, Ohio, where William Burke of the Vulcan Last Company. Burke backed their plan to build a two-place, tandem, open-cockpit parasol sportplane and the Vulcan Aircraft Division began.
The result was the Vulcan “American Moth.” The plane was a hit, but the relationship among the principles was deteriorating and the Doyle brothers left to start their own Doyle Aircraft Company in Baltimore in 1929. They produced fourteen Doyle Orioles which were similar to the Moth before bankruptcy ended the effort.
Doyle Moon Maid ROG-1
Moon Maid started out to be a gyroplane, but after a couple of years the designer/builder, Richard Doyle, decided to turn it into a standard airplane, stretching the fuselage four feet and replacing the rotor with a pair of wings spanning 23.5 feet. He pow¬ered it with a Bob Huggins 1523cc VW conversion of about 50 hp, one of the first homebuilts to use VW power.
The aircraft first took the air (now as N12041) in June 1964. The Moon Maid initially had a 25hp VW1200, later received a 50hp VW1600 and finally a 60hp VW1840.
During its career the aircraft was modified several times and amongst others received a dorsal fin, a slightly enlarged vertical tail and a new cantilever undercarriage with wheel pants.
Although plans were available for amateur construction (for engines in the 35-50hp range), no further aircraft were built.
