Continental Motors O-200 (100-hp) Aircraft Engine

Teledyne Continental Motors O-200 (100-hp) Aircraft Engine

Teledyne Continental MotorsContinental has been producing aircraft engines for since the 1930s.  The company originally built the A40 engine, a 38-hp 4 cylinder horizontally-opposed air-cooled engine used in the Piper Cub. The original engine evolved into various models over the years, including the A65, A75, C75, C85 and C90, and finally evolved into the O-200 engine used in the popular Cessna 150.  Over the years, thousands of small Continentals have been produced (Continental was producing more than 10,000 engines per year in the late seventies).  Today, the O-200 engine is still available factory-new from Continental, and used ones are available from many sources. 

Continental engines provide a history of performance and reliability, with available worldwide parts and service support. Many Zodiac builders have installed used and/or overhauled Continental engines. There is a large market for used Continental aircraft engines, with numerous sources for used engines, parts and after-market upgrades and enhancements.  If using a older Continental engine, we recommend that the engine be upgraded with a lighter (and more modern) electrical system.

Mattituck (Teledyne Mattituck Services) is a subsidiary of Teledyne Continental Motors, the same company that manufactures Continental engines. Mattituck manufactures the 100-hp TMX-0-200-A engine assembled using all new Continental parts.  The TMX (or "experimental") series engines are brand new zero time engines. The TMX engines are outright sales, no core exchange or trade in is required.  The TMX-O-200 engine is not FAA certified, which is why it is sold for significantly less than a comparable FAA-certified Continental O-200 engine. All parts used on the engine, with the possible exception of some accessories, are fully FAA certified components but the engine as a complete unit is not certified.  The 100-hp TMX-0-200-A engine is supplied with a 1,800 hr. TBO, and installs just like the Continental O-200 engine.

"Sebring Sport Aviation Expo 2007: Oh, The Planes!" Review of the factory-built Zodiac XL S-LSA (powered by the O-200) by Rob Finfrock (January 19, 2007, Aero-News Network): 
    "...the all-metal Zodiac is resolutely low-tech by comparison [to composite imports], an excellent example of designer Chris Heintz's philosophy to "keep it simple and keep it light." That, and another axiom -- "if it works, don't fix it" -- have served the design well on the homebuilt market, and also simplified the entry of the S-LSA certified model into the light sport segment. 
"Something of a rarity is the certified Zodiac's powerplant of choice: a FAR 33-certified Continental O-200, same as you'll find in Cessna 150. Unlike the Rotax 912 seen on several other entries, the trusty 100-horse Continental is a rather conventional, low-revving engine, that also carries the added advantage of service availability: nearly any mechanic you'd ever see will be able to work on it
"Unlike several LSA competitors, the Zodiac I flew also sported a true, full-sized, classic-six steam gauge arrangement, front-and-center, with engine instruments to the right. Anyone transitioning from an older Cessna or Piper should feel right at home with this layout (although glass flight instrumentation is one of many options available.) 
"As far as flying impressions, I felt the Zodiac flew like a heavier plane...  due mostly to its somewhat more deliberate response in turns... The Zodiac was quite eager to please, though... and to me, the slower control responses were quite comforting and familiar. In fact, it seemed to fly much like the trusty old Skyhawk does, albeit in a low-wing.
"The word that comes to mind repeatedly when contemplating the Zodiac is "honest": honest construction, honest presentation, and honest flight characteristics."
