1. Technical Concept
Our engine is a series -produced automobile engine from the smart car with belt drive for use as a stationary engine or as an uncertified power train for sports aircraft.
Engine RPM is reduced with the help of a toothed belt drive. Car-like vibration damping is achieved by using a centrifugal clutch with soft torsion coupling.
Note: Since this engine is a variant of a serially produced stationary engine, it does not meet the safety requirements of certified aircraft engines. The engine may therefore only be used in aircraft types where sudden engine failure does not endanger safety. This means that the glide and landing characteristics of the aircraft must not be affected by engine failure, proof of which must be produced during aircraft certification. Therefore, aircraft equipped with this engine must only be flown over such terrain and at altitudes and speeds so that in the event of sudden engine failure, safe landing is always possible, responsibility for which rests with the pilot. Local regulations may apply. For Germany, see Civil Aviation Act (Luft VO) § 6.
The user acknowledges by signing below that engine failure is possible at any time because the engine is used for a purpose other than designed.

Furthermore, any modifications to the engine and/or drive pose potential safety risks. As such, distributors are advised to not undertake any changes prior to qualified engineering analysis and exhaustive testing! Any irregularities, anomalies and damage must be immediately reported to the distributor!
