The C90 was introduced in 1947 as a follow-on to the A65, which had been in production since 1939. [7] [8] Many of the designs powered by the C90 are upgraded variants of earlier A65 powered designs, such as the Piper J-3 Cub and PA-11 Cub Special, [9] Aeronca 7AC, [3] and Luscombe 8A. [10] The engine was developed from the earlier O-190 by increasing the stroke 1 ⁄ 4 inch.

In the 1930s, Lycoming made a number of attempts to develop successful high-power aircraft engines. The 1 200 hp (895 kW) O-1230 was Lycoming's attempt to produce an engine based on the United States Army Air Corps hyper engine concept, and used a variety of features to produce nearly 1 hp/in 3 (46 kW/L) of engine displacement.
Lancair 200 Model first flown in 1984, powered by a 100 hp (75 kW) Continental O-200 engine. Overall length is 19.75 ft (6.02 m). [3] Lancair 235 Model introduced in 1985, powered by a 100 to 115 hp (75 to 86 kW) Lycoming O-235 engine. Overall length is 20.00 ft (6.10 m), slightly longer than the 200, due to the engine and mount dimensions. [3] [2]
The Lycoming O-290 is a dual ignition, four-cylinder, air-cooled, horizontally opposed aircraft engine.It was first run in 1939, and entered production three years later. A common variant of the type is the O-290-G, a single ignition model which was designed to drive a generator as part of a ground power unit.
The Lycoming O-320 is a large family of naturally aspirated, 320 cu in (5.2 L) air-cooled, horizontally-opposed four-cylinder, direct-drive engines produced by Lycoming Engines. Introduced in 1953, it is commonly used on light aircraft such as the Cessna 172 and Piper Cherokee , and remains in production as of 2024.
Thorp T-18 T-18. The Thorp T-18 is an American, two-place, all-metal, plans-built, homebuilt aircraft designed in 1963 by John Thorp. [1] [2] [3]The aircraft was originally designed as an open cockpit aircraft, powered by a military surplus Lycoming O-290G ground power unit engine, but evolved into a fully bubble canopied aircraft powered by engines of up to 200 hp (149 kW).
200 hp (149 kW) at 2700 rpm, Minimum fuel grade 100 or 100LL avgas, compression ratio 8.70:1. Same as the A1A but with impulse coupling magnetos.
