The Colomban Cri-cri (short for cricket) is the smallest twin-engined manned aircraft in the world, designed in the early 1970s by French aeronautical engineer Michel Colomban. With a wingspan of 4.9 m (16 ft 1 in) and 3.9 m (12 ft 10 in) long, it is a single-seater, making an impression, at close range, of a dwarf velomobile with wings.

[edit] Design
The Cri-cri has superior aerobatic performance; capable of 1 roll per second. There are approximately 30 Cri-cri aircraft in airworthy condition in the U.S. and over 100 around the world as of 2003.[citation needed]
The MC-10 Cri-Cri has a cruising speed of 170 km/h (92 knots, 105.6 miles per hour) and a range of 750 km (466 standard miles, 405 nautical miles).[citation needed] The MC-12 model has a cruising speed of 185 km/h (100 knots, or 114.9 miles per hour) and range of 500 km (310.6 standard miles, 270 nautical miles). The MC-15 is powered by two 15 horsepower (11 kW) engines.
[edit] Variants
As with any homebuilt aircraft, the existing Cri-cri planes have often been modified by their builders, departing from the original design to a varying degree, resulting in different performances.
- one flying Cri-cri, F-PZPR, was equipped with AMT Olympus turbine jet engines, increasing the cruising speed to around 240 km/h (130 knots, 149.1 miles per hour).
- In June 2010, EADS Partnered with Aero Composites Saintonge and the Greencri-cri Association, presented a electric powered Cri-Cri at the Green Aviation Show in Le Bourget. The modified airframe with composite components can fly for 30 minutes at 110 km/h. The aircraft uses four brushless electric motors with counter-rotating propellers, which makes the aircraft one of the world's smallest four engine aircraft as well.[1]
- On September 5, 2010 Electravia accomplished a world record speed of 262 km/h (162.33 mph) for a lithium polymer powered aircraft using a Cri-cri with two electric motors (each producing 25 hp) during the attempt. The company claimed engine and cooling drag reductions of 46 percent versus the conventional combustion engine arrangement.[2]
- Kits for homebuilding have been sold by Zenair of Canada as the Zenair Cricket
