ABSTRACT:
A system is provided which enables winglets to be added to existing wing structures of 727 model aircraft to increase fuel efficiency while providing a means for redistributing additional loads created by the winglets so that modified aircraft can be operated safely and within government regulations. Re-setting of existing wing flaps and ailerons safely offsets the load increase caused by the addition of winglets and also contributes to increased fuel efficiency. An airplane wing modification kit comprises a winglet and modified components for re-rigging the settings of ailerons and flaps of existing 727 model airplanes.
