It was in 1971, when aircraft designer Michel Colomban started work on this small aircraft Cri Cri with two engines. His target was to build small, economic plane with two engines, which would be able to flying also some aerobatic maneuvers. Colomban originally planned the Cri-Cri in wood and fabric.

A spar was made with a thin plywood web, but with alloy caps glued on. The bonding was so effective, and the alloy so quick and easy to use, Colomban decided to go toward metal construction, using a lighter material than aluminium for the non-stressed parts of the inner structure. In time he settled on Klegecell, a polyvinyl-chloride (PVC) foam.
The wooden wing was planned to have an NACA 23012 section, but the foam/metal wing used a Colomban-modified Wortman 19% thick design. This changed to 21.7% later. The par is AU 4 G-1 alloy with an I-beam section. The ribs, 32 per panel in the prototype, were sawed out of a stack of Klegecell sheets.

Price of this plane shouldn’t exceed 1000 USD, including two engines – these prices are from 1970. Construction took around 1500 working hours for the Cri-Cri plane, which name is after nickname of Michel’s daughter, prepared for it’s first flight. The prototype was first flown in 1973, with two 9 hp engines.
The Cri-Cri features brakes, flaps, full harness, nosewheel steering and inflight adjustable rudder pedals. The prototype had ground adjustable variable pitch 68cm / 26.75in in diameter.
Cricket is fully aerobatic (at 170 kg) and was built in France under the approval of the French EAA, the Fleseau du Sport de LAir (RSA).
CriCri is the world’s smallest twin-engine airplane at 16 feet and 160 pounds. Powered with two 12-hp Swedish snowmobile Valmet engines, the tiny twin was first shown at the 1981 Oshkosh Fly-In.

With trhe help of a Canadian businessman, worldwide marketing was established. Development of a kit to accompany the plans soon followed.
The kit product diverged from the original design in a few critical areas, notably, the flaperon torque tube. The new company elected to replace the aluminium tube with a steel one of smaller diameter. The steel tube had some torsional flexibility that harmonised with the flaps themselves and a few crashes resulted from severe flutter problems.
Unaccustomed to huge damages sought in the US lawsuits ($10,000,000) Colomban, whose relationship with the Canadian company had cooled considerably, pulled the airplane from all markets in the Western hemisphere. The company was forbidden to sell kits for the Cri-Cri and spare parts suddenly disappeared.
After those Yves Duval and Nicolas Charmont, a third Cricri jet was flying in France. Dominique Bonnaire made him his first flight in this configuration on May 5, 2011. The engine selected was 2 Jetcat P200SX giving a thrust of about 45 kg.
Dominique Bonnaire was the builder and owner of this Cricri, flying since 1996.

The Collyer-Lang “Otasel” single-seater monoplane tested at Brooklands between November 1910 and February 1911, only achieving brief hops. It was a pusher with twin rear booms, with the pilot seated ahead of the wings between the two front skids. Inset single acting ailerons provided lateral control, and twin rudders within the booms and a tail mounted elevator comprised the other control surfaces. The engine was a 30hp WLA (Adams) motor.

The Dipper Amphibian is a two-seat amphibian of metal and glassfibre construction (first flown 1982).
A plans only design, not in production.
Reports that the boat hull of the Aqua II was used in the homebuilt Collins W-7 Dipper, flown August 28, 1982 as N25WC, are incorrect. The Collins Dipper project was converted from a damaged Cessna 150 and had a new boat hull fitted below the fuselage. The boat hull was designed by the Aqua designer Meredith Wardle and was about 92% in size of the Aqua II boat hull.

Spencer and ex Sikorsky engineer Vincent A. Larsen designed the single engine SL-12C amphibian in 1969. It was a two-place, high wing monoplane. The main wheels located in rearward-retracting wing floats; motor in hull drove the prop on a shaft above the fuselage.
First flying in May 1939 registered NX20621, piloted by Percy Spencer, flight tests exposed so many problems with the design and construction that the plane was dismantled after logging 10 hours, and the company reorganized as Colgate-Larsen.
Colgate-Larsen Aircraft Corporation succeeded Spencer-Larsen Aircraft Corporation around 1940, continuing its work at Amityville, Long Island, NY, on novel-design small four-seat amphibian flying-boat, the CL-15 (formerly SL-15).

Spencer leaves Spencer-Larsen in September 1940 and starts the work on his own S-12 Air Car amphibian design.
