Where can I find a Stemme S10 for sale?

Most are listed in Germany (3), followed by France (2), Spain (1) and United States (1). Each listing links straight through to the seller, so a Stemme S10 in another country is worth considering rather than filtering out.
What should I check when buying a used Stemme S10?
On a used Stemme S10, check airframe hours, engine time since overhaul, avionics generation and damage history before anything else. PlaneFox recommends a pre-purchase inspection by an EASA Part-145 shop that knows the type, which typically costs EUR 1,500 to EUR 3,500. Under 1,500 airframe hours is low-time and above 3,500 means budgeting for higher maintenance; most piston engines run a 2,000-hour TBO, so past 1,500 to 1,700 hours since overhaul expect the overhaul within one to three years at EUR 25,000 to EUR 45,000. Read the full logbook history for prop strikes, gear-up landings and structural repair, and confirm ADs and SBs are complied with.

About the Stemme S10

Aircraft overview

The Stemme S10 is a German self-launching motor glider developed by Stemme and first flown in the 1980s, with production continuing through several S10 versions before later Stemme designs appeared. It is a two-seat, side-by-side aircraft built around a 23 m high-aspect-ratio wing, retractable landing gear and a distinctive nose propeller that folds away when the engine is shut down. Its significance is that it combines true soaring capability with practical powered touring, avoiding the drag penalty of a conventional exposed propeller.

Performance & specifications

Performance depends on variant and equipment, but the S10 is typically used as a fast touring motor glider rather than a conventional light airplane. Powered cruise is commonly in the area of 100 to 120 knots, while the aircraft retains a glide ratio of about 50:1 in soaring configuration. The S10-VT uses a turbocharged Rotax 914 engine rated at 115 hp, mounted behind the cockpit and driving the folding nose propeller through a shaft. Earlier S10 versions used lower-powered Rotax installations. Useful load is modest by airplane standards and must be checked aircraft by aircraft, especially where oxygen, avionics upgrades or heavy interiors have been added. Published ceilings vary by model, with turbocharged aircraft offering substantially better high-altitude capability than normally aspirated examples.

Cabin & avionics

The cabin seats two occupants side by side under a large canopy, with good visibility for soaring and touring. Space is closer to a high-performance sailplane than to a four-seat aircraft, so buyer expectations should focus on efficiency and endurance rather than baggage volume. Avionics are highly individual on used S10 aircraft. Typical panels may include a VHF radio, transponder, engine monitoring, electric variometers, flight computer, GPS and soaring navigation equipment from brands such as LXNAV, Cambridge, Becker, Trig or Garmin retrofit units. Integrated Garmin Perspective or G1000 suites are not typical for the Stemme S10.

Buying & value

Used-market evaluation should focus on airframe history, composite condition, retractable gear operation, propeller folding mechanism, driveshaft system, engine hours, cooling, turbo condition on S10-VT aircraft and the status of sailplane-specific instruments. Maintenance familiarity matters, because the S10 is more specialized than a standard touring airplane. Common distinctions include earlier S10 models and the S10-VT, with many aircraft upgraded over time with modern radios, transponders, GPS, oxygen systems or soaring computers. On PlaneFox, current Stemme S10 asking prices average about EUR 157,000, with observed listings from roughly EUR 95,000 to EUR 279,000, placing it in a niche market where condition, variant and avionics can move value significantly.
