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

By now, production of the redesigned Laser 300 was running one year behind schedule, and the projected cost of the airplane had risen from $US 550,000 to $875,000, albeit for a more capable aircraft. The aircraft was displayed at the NBAA show in Dallas, Texas in
