It was in 1978, in Canada, that Dale Kramer designed the Lazair, one of the first twin-engine ultralights. Though it was introduced before Part 103 came into being, the Ultraflight Sales Ltd. Lazair was a true pioneer, an airplane which helped define the ultralight class.

This single seat, aluminum-tube-constructed aircraft was made to get the most performance out of a very small amount of power. Featuring an inverted V-tail with a landing skid on the bottom of each side and a very small nose wheel up front (which is never used if the landing is done right). The big transparent, Tedlar-covered wings are equipped with large effective ailerons and drooped tips for excellent low-speed controllability. The wings remove for easy transportability.

It's powered by two 9.5 hp Rotax 185s, each throwing two, two foot-long propellers. Although 9.5 hp each may sound measly, its all the Lazair needs to achieve excellent flight performance.

The Lazair's tank is mounted just behind the pilot seat. Just add a little fuel and off we go!

With both engines purring away the performance of the aircraft is quite good. It can easily cruise at 45 mph burning a combined two gallons an hour. The airplane takes off in 150 feet or less and lands in about the same. It has a very slow sink rate (333 feet per minute) and the plane can be soared like a sailplane if you have strong enough lift conditions.

"Low and slow", the Lazair flys hands off at very low speeds.
