Dynamic WT9 Mcr-4s

Single Piston

The Dynamic WT9 (ICAO: MCR4) is a French-designed two-seat ultralight and light sport aircraft that has carved out a niche in the European recreational aviation market since its introduction in the early 2000s. Built by Aerospool in Slovakia under license from French designer Dynamic, the MCR-4S variant represents the company's focus on efficient cross-country performance within ultralight weight limits. With its sleek composite construction and low-wing configuration, the type appeals to pilots seeking something sportier than traditional high-wing trainers while remaining accessible under European microlight and American LSA regulations. The aircraft's 1,320-pound maximum takeoff weight places it precisely at the upper limit for the light sport category in the United States, though it sees most of its service in France and Italy where the registration patterns suggest concentrated operations. Powered by a single Rotax 912-series engine producing around 100 horsepower, the MCR-4S cruises comfortably at 120-130 knots while sipping fuel at rates that make it economical for flying clubs and private owners. Its stall speed of just 37 knots with flaps deployed provides comfortable margins for short-field operations, and the never-exceed speed of 151 knots gives pilots reasonable speed capability without venturing into the performance envelope that would require more complex certification. The type's relatively modest numbers in service reflect its position as a specialized European ultralight rather than a mass-market trainer, but those who fly it praise its handling qualities and efficient design.
