Spirit 15

The Spirit 15 wing is the result of 2 years of development. Using state-of-the art wing design principles, sound manufacturing and best quality materials, the result is a wing that handles well, is incredibly strong and performs like a winner! This wing is especially noted for its large cruise speed range, great handling in turbulence and most significantly – its superior climb rate. This wing should be a definite choice for anyone flying from higher elevations or with smaller power-plants.
