Sierra Sierra - This glider fills the gap between the Santana and Allegra and will pioneer a new class of its own - to be called "Supersport Class" Top Performance Standard Class. This glider is capable of combining the performance of Allegra with safety and handling- both on the ground and in the air, suitable for the intermediate pilot. Imagine Allegra with Standard Class certification, handling, and launch characteristics of an intermediate glider. Its shape is similar to Santana, but built with diagonal rib technology, ensuring greater performance and speed range than the Santana. Sierra stands out against the rest of the crowd due to its unique blend of outstanding performance, reassurring stability and friendly behavior. 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. Flying the Sierra will become a pleasurable addiction!
