The Aerospool, Spol WT 9 Dynamic is a Slovak fixed-wing light-sport and ultralight aircraft. It serves in a role suitable for two occupants, featuring a cantilever low-wing layout with a side-by-side enclosed cockpit. The propulsion comes from a single engine driving in tractor configuration, paired with a tricycle landing gear arrangement that can be fixed or retractable depending on setup.
Produced in Prievidza, the aircraft is constructed using carbon fibre sandwich materials and complies with various international microlight and light-sport regulatory frameworks. Standard powerplant choices include several four-stroke models, and operators can optionally equip the machine with a glider towhook. The foundational design also served as the basis for a larger three to four seat derivative model.
