The S-44 Mystere is an all-composite design with kits made available to homebuilders by Partenair Designs IInc. of Boucherville, Quebec. The S-45 was derived from the company’s first design the S-44 Mystere (1 built) which was first flown in 1997 powered by an 80hp (59kW) Rotax 912 and with a maximum take-off weight of 1199lb(544kg). Unfortunately this aircraft was destroyed on a test flight and after a complete redesign the S-45 emerged as a larger more powerful version of the S-44.
