Flying models construction may differ from that of static models as both weight and strength are major considerations.

Flying models borrow construction techniques from full-sized aircraft although the use of metal is limited. These might consist of forming a frame using thin planks of a light wood such as [[Ochroma pyramidale|balsa]] to duplicate the [[former]]s, [[longeron]]s, [[spar (aviation)|spar]]s, and [[rib (aeronautics)|ribs]] of a vintage full-size aircraft, or, on larger (usually powered) models where weight is less of a factor, sheets of wood, [[expanded polystyrene]], and [[wood veneer]]s may be employed. It is then given a smooth sealed surface, usually with [[aircraft dope]]. For light models, tissue paper is used. For larger models (usually powered and radio controlled) heat-curing or heat shrink covering plastic films or heat-shrinkable synthetic fabrics are applied to the model. Microfilm covering is used for the lightest models and is made by spreading few drops of lacquer out over several square feet of water, and lifting a wire loop through it, which creates a thin plastic film.
Flying models can be assembled from kits, built from plans, or made completely from scratch. A kit contains the necessary raw material, typically die- or laser-cut wood parts, some molded parts, plans, assembly instructions and may have been flight tested. Plans are intended for the more experienced modeller, since the builder must make or find the materials themselves. Scratch builders may draw their own plans, and source all the materials themselves. Any method may be labor-intensive, depending on the model in question.

To increase the hobby's accessibility, some vendors offer [[Almost ready to fly|Almost Ready to Fly]] (ARF) models that minimize the skills required, and reduce build time to under 4 hours, versus 10–40 or more for a traditional kit. [[Ready to Fly (radio control)|Ready To Fly]] (RTF) radio control aircraft are also available, however model building remains integral to the hobby for many. For a more mass market approach, foamies, injection-molded from lightweight foam (sometimes reinforced) have made indoor flight more accessible and many require little more than attaching the wing and landing gear.
