N5121 (“Fifty-one to one”… the plane’s glide ratio). Serial number 11-023. This immaculate side-by-side self-launching sailplane is equally well suited for thermal, wave, cross-country soaring and self-sufficient soaring safaris. It is an FAA Certified aircraft powered by a 115hp turbocharged four-cylinder Rotax 914F powerplant. Meticulously maintained and always hangered, this Stemme is a true touring motorglider with 1000+ mile range, 31.7-gallon fuel capacity. Maximum powered cruise speed is 140kts, burning about 4 gph. Electrically retracting main landing gear and steerable tailwheel allow for easy ground operations whether at controlled airports or remote gliderports. The Stemme’s robust centerline thrust folding propeller and reliable drive train transitions between powered and soaring flight in only four seconds with negligible drag and no pitch trim change while deploying and retracting. In flight, its 23m/75-foot wingspan delivers high performance while soaring or powered. On the ground, easy wing-folding permits taxiing, tying-down and hangering with a span of only 38 feet. Owned since new by Stemme USA’s founder. Selling to make room for a Stemme S12. Serious inquiries welcome at Marc@RockyMountainSoaring.com.
