We Fly: Stemme S12

Gemini Sparkle

Key Takeaways:

  • The Stemme S12 is a high-performance motorglider that uniquely combines powered flight and pure soaring, featuring a retractable engine for takeoff and backup that seamlessly disappears for silent, engineless flight.
  • With an 82-foot wingspan, the S12 boasts an impressive 53-to-1 glide ratio, allowing pilots to sustain flight by skillfully locating and utilizing thermals (rising air).
  • The aircraft offers a silent, skill-based, and emotionally engaging soaring experience, enhanced by features like side-by-side seating, excellent visibility, and specialized avionics for thermal detection, all while reducing "landing out" anxiety due to its onboard engine.

Soaring is quite unlike any other kind of flying. Plunk yourself down in an open field on a warm, sunny day, as I did last fall, and watch a hawk, wings outstretched, wingtips moving only slightly to adjust the flight path as they trace seemingly endless patterns across the sky in search of a meal. Natural soaring is silent, so quiet, in fact, that a hawk circles unnoticed unless eyes happen to turn skyward.
