Master the fundamentals with nature's own design secrets. The Cetara applies biomimicry through tubercle technology—the same leading-edge bumps that allow humpback whales to perform impossible maneuvers. This 40mm EDF trainer combines forgiving flight characteristics with revolutionary aerodynamics, making it perfect for pilots transitioning to jets or exploring bio-inspired design. The tubercles create vortices that energize airflow, dramatically reducing stall speed while maintaining control authority at high angles of attack. Translation: slower landings, gentler stalls, and a wider flight envelope than conventional trainers. Slot-together assembly gets you flying in an afternoon, while the aerodynamic innovations deliver a flight experience foam jets simply can't match.
