ABSTRACT:
A model airplane jig is disclosed which is particularly adapted to support a model gasoline engine airplane in substantially any position or orientation so that repairs can be made to the same. The jig includes a weighted base and a vertical post extending upwardly therefrom. A horizontal beam is pivotally connected to the top of the post through a ball joint and trunnion with the connection being radially offset from the axis of the post. Front and rear wheel clamps adjustably mounted adjacent the ends of the horizontal beam attach to the wheels of an airplane and secure the plane to the jig.
