Wing Construction

The wing of a model aeroplane that is intended to fly may be constructed in a number of ways depending on the required performance envelope of the model aircraft.

Each type of wing construction has it's own pro's and con's:

  • Open balsa wood structure: Light, asthetically pleasing, rigidity dependent on construction and covering, difficult to repair.
  • Veneered foam: Strong, rigid, easy to repair, heavy.
  • Balsa veneered foam with woven cloth and resin covering: Very strong, rigid, requires expertise to produce a matching pair that are light.

All of types of wing construction are very dependent on the final covering for their ultimate strength and durability. If weight is to be kept to a minimum then the final covering should be considered carefully.
