Many non-competition pilots installed Masak's winglets for the handling benefits as well. The benefits are notable, because sailplane winglets must be removable to allow the glider to be stored in a trailer, so they are usually installed only at the pilots' preference. Today, following on the work of Masak and Maughmer, new glider wings are designed concurrently with the winglet, achieving higher efficiency than retrofitted winglets, with drag less than the theoretical minimum for a fully elliptical wing of the same span.
