发明名称 Propulsion system for model airplane
摘要 An improved structure and method for powering the flight of a model airplane by positioning the motors and propellers on the back side of the top wings of an airplane using a single or double-deck wing design so that the propellers and motors of the airplane are better protected from damage in the event of a crash. The fuselage of the airplane is formed of a deformable material such as a foam to aid in crash resistance.
