It is a canard layout powered by a pusher turboprop engine, and a high, swept wing carrying endplate fins on the tips.

The first prototype flew on 11 December 1981[4] and OMAC ("Old Man's Aircraft Company") hoped to obtain type certification by mid 1982.

[5] A second prototype flew on 19 February 1983,[5] and certification was expected "no later than December 1984",[6] but in late 1983, the process had barely started.

[13] This machine was built alongside three other Laser 300s, together representing the first four of thirty aircraft that Omac hoped to build by the end of 1987.

[15] The aircraft was displayed at the NBAA show in Dallas, Texas in October 1988, by which time 56 hours of flight testing had been carried out without incident.
