The Stemme S6 is a two-seat touring motorglider manufactured by Stemme AG. Unlike the S10, the S6 has a non-retractable three-bladed propeller (that can feather like other touring motor gliders), a wider fuselage design, and tricycle landing gear, available both with fixed and retractable configurations. Its engine is a Bombardier-Rotax 914, the same engine used in the Stemme S10-VT.[2] The designers placed great importance on noise and vibration reduction.
