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.
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]
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.

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).
The Lycoming O-235 is a family of four-cylinder, air-cooled, horizontally opposed, piston aircraft engines that produce 100 to 135 hp (75 to 101 kW), derived from the earlier O-233 engine. [ 1 ] [ 2 ]
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. [4] IO-360-A1B6 200 hp (149 kW) at 2700 rpm, Minimum fuel grade 100 or 100LL avgas, compression ratio 8.70:1. Same as the A1B but with a crankshaft that has one 6.3 order and one 8th order counterweights.
The 130 hp (97 kW) O-240 was a new engine design derived from the six-cylinder Continental O-360 and introduced in 1971. It is generally similar in overall dimensions to the Continental O-200, but with a higher 8.5:1 compression ratio, designed to run on 100/130 avgas. The O-240 delivers 30% more power than the O-200 while it weighs only 12% more.
