This invention is a tubular shaped flying toy comprised of a polypropylene (foam) main cylindrical body with a heavy plastic ring supported front end. The main foam body is held in place to the plastic ring support with the help of rubber bracelet bands that stretch around the outside of the front end of the toy where the foam body stretches onto the hard plastic ring. The toy is thrown with a baseball type throwing motion, and provides a graceful, smooth flight.

A modular wing, adapted to be used on a flying device such as a toy airplane, drone, or other small fixed wing flying device, or form a part of a wind turbine or any other apparatus that requires a wing or blade, that is compatible with all block-based toy systems such as LEGO®, DECOOL® or KAZI®. The modular wing is comprised of a series of modular aerodynamic surfaces that may be suitable for manufacture by a low-cost method such as molding or additive manufacturing such as 3D printing, typically but not necessarily from plastic, to form wing sub elements which, when assembled together, form a wing or blade such as an airplane wing or turbine blade. The modular wing may comprise cambered or symmetric wing shapes. The modular wing may be used in a static display model fully flying aerodynamic aircraft, sailing hydrodynamic boat, or aerodynamic functioning turbine.

Disclosed here are systems for detachable airframe components including detachable nose cones, propeller assemblies and motors. In some example embodiments, the assemblies include a nose cone with a connection receiver, a motor assembly with a rotatable section, where the rotatable section includes torque arms configured to secure with the nose cone connection receiver, and a propeller assembly, configured to connect to the nose cone.

An inflatable toy plane assembly is provided. The plane assembly includes inflatable wings, an inflatable fuselage, an inflatable empennage (tail area stabilizers), and/or other inflatable elements. Not all elements of the inflatable plane assembly are required to be inflatable, e.g., the wings may be inflatable, and the fuselage may not. The plane assembly preferably includes one or more valves to facilitate the inflating and deflating of the plane's inflatable elements. In use, the inflatable plane assembly is deflated for compact storage (e.g., rolled up) and subsequently inflated when preparing the assembly for flight. The plane includes detachable wings and/or detachable tail stabilizers that are detached for storage, and subsequently reattached to the plane's fuselage and inflated for use.

A kit and assembly for mapping out steps in a build process for constructing a model replica including a mapping key containing a plurality of symbols corresponding to different fabrication operations associated with the build process. One or more template boards are provided, each containing one or more replica parts and having a sub-arrangement or scheme of symbols drawn from the mapping key for providing a subset build step. Assembly of the foam board replica can be expedited, with or without reference to separate instructional videos which can be provided for any specific replica kit.

A multi-layer, super-planar structure can be formed from distinctly patterned layers. The layers in the structure can include at least one rigid layer and at least one flexible layer; the rigid layer includes a plurality of rigid segments, and the flexible layer can extend between the rigid segments to serve as a joint. The layers are then stacked and bonded at selected locations to form a laminate structure with inter-layer bonds, and the laminate structure is flexed at the flexible layer between rigid segments to produce an expanded three-dimensional structure, wherein the layers are joined at the selected bonding locations and separated at other locations.

A method for registering one of a plurality of assembly modules operatively coupled to one another in a modular assembly system is provided. A first message including a first identifier of the assembly module is received from one of the plurality of assembly modules. A second message including a second identifier for the assembly module is transmitted to the assembly module. The second identifier is generated based on at least the first identifier. A third message including the second identifier is received from the assembly module. In response to determining that the third message is received, the assembly module is registered as a new assembly module of the modular assembly system. At least one of the receiving, transmitting, determining, and registering is performed by a control module of the plurality of assembly modules.

A method for beautifying a balsa wood model aircraft with a thermal shrink covering film, so that the balsa wood model aircraft with a thermal shrink covering film is obtained. This method makes a model aircraft colorful, reduces labor costs, improves the beautifying and painting effect of the model aircraft, and also improves the pneumatic performance of the model aircraft.
