Abstract
The present invention is directed to a positive removable mounting of a wing and, if desired, the tail assemblage. This attachment provides a spring biased mounting means at one side of the mounted member and one or two pins or dowels are inserted into receiving holes provided. The opposite side is brought to fixed hole portions and one or more fixed pins or dowels are placed in these holes. The wing or tail assembly is rearwardly moved with and by bias to retain the wing or tail in position until moved forwardly. This forward movement is produced by a crash or sudden stop or by the operator when he wishes to disassemble the craft.
