The composite model construction uses a semi-flexible expanded polypropylene foam plastic core with a thin, semi-rigid polycarbonate plastic shell adhesively attached to the core. The core includes various rigid structural members installed therein, as required, for sufficient structural stiffness for the model. The core and plastic shell components may be formed by injection molding, vacuum forming, or other processes. The model construction method provides a highly accurate outer surface for a model, with the outer shell being formed with scale details, such as panel seams, rivet lines, etc. during the molding or forming process. A motor or other prime mover may be added to the composite model body. The materials used in the composite model are resilient with a flexible yet tough outer shell to resist impact damage, and allow repairs to be made quickly and easily when required.
