Abstract: The present invention provides an unconventional and proprietary radio control (RC) or infrared remote control (IR) toy model/airplane which can intentionally shift or change its center of gravity (COG) to different positions along the longitudinal centerline of the aircraft or fuselage. The incremental shifting or moving of the COG from front to rear or vice versa incrementally changes the “angle of attack” of the wing, thereby producing a variable range of viable flight attitudes and resultant terminal velocities (top speeds). Therefore, users can easily select an appropriate speed for the airplane to fly in limited indoor spaces or in larger outdoor areas. Additionally, the COG shifting of the present invention can be applied not only to RC and IR controlled toy models/aircrafts but may also be implemented into real aircrafts including manned and unmanned aircraft for civilian and/or military applications.
