It has a retractable tricycle landing gear and the enclosed cockpit has two seats side-by-side with dual controls and a zero/zero pilot extraction system. The Stalker has two underwing hardpoints outboard of the landing gear for military ordnance. The prototype was destroyed in a fatal accident on May 29, 1989.
