July 29, 2013 - German's high-end motorglider manufacturer Stemme is relaunching its brand at EAA Oshkosh 2013 with a fresh design, new management team, and new features on the well-established S10, known for its unique fold-away propeller. New CEO Paul Masschelein is also highlighting the latest updates to the S6-RT model.
"Stemme is pushing especially for the North American market" Masschelein said.
New dealer and service partnerships are being established throughout the U.S. close to its customer base. The company plans to offer demo flight opportunities in the motorgliders just after AirVenture in Oshkosh; demos are also any time at Stemme USA headquarters in San Diego, California.
Stemme's flagship S10 motorglider boasts a 50:1 glide ratio, retractable fold-away variable pitch propeller, and power from a turbocharged Rotax 914 engine. With side-by-side seating and an electrically retractable gear, the S10 also boasts a reconfigured glass panel with engine management system (EMS) and new Butterfly variometer, a new hydraulic brake system and four-point automatic seat belts.
Inside, the S10 sports a fresh "technical" interior design in light green and graphite.
The Stemme S6-RT, for retractable/turbo, is a new concept of a travel motorglider with a high maximum takeoff weight of 1,980 pounds, fully retractable tricycle landing gear (with trailing links on the mains), and the reliable Rotax 914 turbocharged engine.
Stemme engineers placed the engine mid-fuselage, where it is barely audible in cruise. Thrust comes via a carbon fiber drive shaft turning a fully feathering three-blade prop. The S6-RT also features side-by-side seating, making for comfortable cruising at 140 knots on about 5 gph to go places fast or soaring at a 36:1 glide ratio.
And flying Stemme's S6 and S10 requires only a glider certificate with a motorglider endorsement.
Stemme's new management was appointed in November 2012 after two long-term shareholders and passionate Stemme pilots increased their investment to own 70 percent of the company's stock, which was founded in 1984.
"Stemme is here to stay," Masschelein said. "I am convinced that we have great prospects with our exceptional motorgliders - the S10 and S6. We are creating a future."
