A rakelet comprises a raked portion and a winglet portion that selectively integrate features of raked wingtips and winglets into a wingtip device that improves aircraft endurance and range over standard wings and over other wingtip devices such as raked wings, winglets, and the like. The features of the rakelet can be configured to improve and maximize the range and endurance for any particular aircraft.
