Jean Roché experimented with a C-3, removing the main landing gear and substituting one wheel in the center of the fuselage. The wingtips had small tricycle wheels for launching and for the end of a landing roll. Quite a bit of weight was saved (about 40 pounds) and aerodynamic drag reduced. The C-3 was personally owned by Roché and shown in registers only as a racer. It was used in a race or two in 1933 wearing race number 17 (NR12407) then returned to conventional configuration. It came in third in a 115-c/i free-for-all.

Aeronca C-2 / PC-2 Scout
Jean Roche, an Air Service engineer at Dayton, Ohio saw a need for an affordable and reliable light aircraft. In 1924, 1n conjunction with John Dohse and Harold Morehouse he designed a small, basic single-seat monoplane powered by a two-cylinder Wright-Morehouse engine. This aircraft failed to attract much interest due to the popularity of the Curtiss Jenny at the time. Following the departure of Dohse and Morehouse to pursue alternative ventures, in 1929, Roche sold his design to the Aeronautical Corporation of America. Further design work was done on the aircraft and in 1930 the Aeronca C-2 was produced. During the 1929 stock market crash the C-2 proved very popular due to its simplicity, low purchase price and low running costs. Aeronca produced this but quickly developed it into the two-seat 36-hp C-3 that remained in production into 1936.
Cincinnati’s Aeronautical Corp. of America debuted the Aeronca C-2 at the Los Angeles Air Races of 1929 and officially introduced it in 1930. The single place C-2 (first (X3774) flying on 24 October 1929 piloted by Fred Fluck) was similar to the 1925 “Roche-Dohse” fliver plane, the PC-2 being a pontoon equipped model. The first production aircraft (X626N c/n 2) was the beginning of the 22-year Aeronca line.
Construction of the C-2 was conventional, utilizing a high-braced wing with two spruce spars and a welded steel-tube fuselage covered with fabric. Production totaled 167, including the C-2N Deluxe Scout version of 1931, which featured a 36-hp Aeronca powerplant. Two C-2N were built (NC13083 and NC13089) plus 1 converted from a C-1, and one from a C-2 (NC643W). The increased horsepower added about 20 mph to the C-2’s top speed and cruise speed but limited its range to 175 miles. Three were PC-2 on wooden floats. Several were built as two seat models. The C-2 sold for US$1545 and the PC-2 Scout for US$1245 in 1931. The C-2N sold for US$1695.

AISA I-115
The 1950 I-11 aircraft was followed by the I-115 basic trainer with revised fuselage. Originally designed by Iberavia S.A., series production was undertaken by Aeronautica Industrial S.A.
First flown on 16 July 1952, 450 were delivered overall. Construction is all wood. Full dual controls and instrumentation are fitted.
Two hundred were ordered for the Spanish Air Force during the mid-1950s, designated E.6, to replace the CASA-built Bucker Jungmann primary training biplane.

AISA AVD-12 / I-18
The I-18, or AVD-12. was designed by Emile Dewoitine to meet the Ministerio del Aire specification issued in 1953, for a two/three seat air observation and liaison aircraft to replace the Fieseler Fi 156 Storch then in service with the Spanish Air Force.
The specification called for a maximum speed of not less than 109 mph, minimum speed of not more than 37 mph, and an endurance of 2.5 hours.
A high-wing all-metal monoplane, the A.I.S.A. I-18 has full-span high-lift flaps with prominent guides.

AISA I-11B Peque
Designed and built in 1950 the I-11 two-seat lightweight training/sporting aircraft. Two prototypes were built.
In 1954, AISA purchased the Spanish manufacturer Iberavia and took over the I-11 light plane project, eventually building around 400 examples as the AISA I-11B, with smaller canopy and tailwheel undercarriage.
Derived from the I-11 prototype, the I-11B differed from the production model in having a fixed nosewheel undercarriage and a larger cockpit canopy. The I-11B first flew on 16 October 1953. Inaugurated early in 1954, a production batch of 70 was built for Spanish Aero Clubs.
Some aircraft were powered by a 93 hp RNMA Flecha engine. Some 450 were built.

AISA HM.9
A glider tug built 1943
AISA HM.7
The HM.7 was originally designed by the Instituto Nacional de Tecnica Aeronautica (I.N.T.A.) and was first produced in 1946.
The HM.7 is a four-seat touring monoplane powered by a 240 hp Argus As 10c engine with wing and tail assemblies of wood, the fuselage of welded steel tube with fabric covering. The enclosed cabin seats four with automobile type doors. Full blind flying equipment was fitted.
No production of the HM.7 was undertaken owing to the lack of a suitable nationally designed engine.
Engine: 240 hp Argus As 10c
Wingspan: 33 ft 5.5 in
Length: 25 ft 9 in
Height: 7 ft
Empty weight: 1540 lb
Loaded weight: 2640 lb
Max speed: 162 mph
Cruise: 118 mph
AISA HM.5
The HM-5 derivative of the Huarte-Mendicoa family of light aircraft took the air in 1943. This aerobatic single-seat monoplane was basically a scaled-down version of the HM-1 powered by the very same engine, adapted for inverted flight. With the HM’s handling horrors untouched, less wing area and the same engine (160hp Hirth 506), only two were produced.
In 1950 José L. Aresti was designated to take part at the Fête Aérienne de Villacoublay aerobatic contest with one of these, however, in the end and he was called back.
AISA HM.3
In essence a floatplane variant of the HM.1. The two HM.3’s built were tested at the end of the 1940s. Certain problems soon appeared, mainly questionable float design and lack of power. The Spanish AF didn’t show any further interest in them and that was the end of it.
