A modularized airplane includes two separably interconnected modules. A first module, incorporating substantial airplane styles, includes a fuselage portion and at least one wing or stabilizer with an associated control surface. A second module carries a set of essential flight components sufficing airplane operations, including propulsion unit, servo for moving control surface, and power source. Magnetic connectors affixed on the modules facilitate inter-modular structural connection. A control linkage assembly, linking control surface on first module and associated servo on second module, is formed with two portions longitudinally movable and separably connected by two magnetic connectors oppositely affixed on each portion. The structural connection and the servo-to-control surface linkage assembly facilitate substantially effortless inter-modular connections to form a functional airplane, as well as nondestructive inter-modular disconnection. The second module can be connected to different aerodynamic styled first modules to form airplanes for different applications, using same essential components.
