Apco Sierra

apcosierra


This 1997 glider filled the gap between the Santana and Allegra and was capable of combining the performance of Allegra with safety and handling, both on the ground and in the air. Suitable for the intermediate pilot, its shape is similar to Santana, but built with diagonal rib technology, ensuring greater performance and speed range than the Santana. A fusion of Santana planform and the advanced diagonal rib design, with the tunable brake technology employed on competition wings. This enables Sierra to offer a level of flight never available before in a Standard rated package.
