Light Sport Aircraft and the Sport Pilot License

In 2004, the Federal Aviation Administration approved the creation of the Sport Pilot License and the Light Sport Aircraft Category. With this addition, flight became more affordable and achievable by the general population. Unlike Private Pilots, Sport pilots are not required to have an annual medical, and can fly with no more than a current driver’s license (after successfully earning the Sport Pilot license).

Light Sport Aircraft (LSA) are single engine planes with no more than two seats, a maximum weight of 1300 lbs, a maximum stall speed of 51 mph and a maximum speed of 138 mph. Light Sport Aircraft can be homebuilt or purchased completed; however, there are many benefits to building your own aircraft.

When built according to the design, the CH650, CH701 STOL, CH750 STOL and CH750 Cruzer are all categorized as Light Sport Aircraft and would be an excellent choice for any Sport Pilot. More info…

Designer Chris Heintz, 1938 – 2021

An accomplished aeronautical engineer, Chris Heintz was a graduate of the ETH Institute in Switzerland. As a young man, Heintz began to design and build his own all-metal homebuilt aircraft incorporating simple construction methods throughout. As founder, president and chief engineer of Zenair Ltd. since 1974, Mr. Heintz designed and developed more than 12 new aircraft models, which have been marketed as kit aircraft around the world. Thousands of Heintz designed aircraft are flying around the world in 48 different countries. Heintz designs have earned an excellent reputation among pilots, builders, the press, and aviation authorities for their durable all-metal construction, normal flight characteristics, reliability, and low maintenance requirements. Chris Heintz not only designed, developed and promoted aircraft, he was also actively involved in all facets of sport aviation as a long-time EAA member, frequently giving lectures and forums at chapter meetings and fly-ins, and consulted governments and aviation organizations. After retirement, Heintz wrote a detailed book on light aircraft design and construction, titled Flying On Your Own Wings, first published in 2009. More…


Engine Options

The Zenith aircraft are designed to provide attractive performance using efficient and lightweight new-generation aircraft engines, like the UL Power and Jabiru 3300, while also being suitable for traditional but heavier aircraft engines such as the Continental O-200 and Lycoming O-233 / 235.While all aircraft are designed within certain power and engine weight guidelines, Chris Heintz did not design these aircraft “around” a particular engine – to maximize the customer’s choice of installed powerplant. Recommended power is 100 to 125 horsepower, up to 300 lbs. installed weight. More…
