Engine for extreme 3D and towing flights

Thanks to its power performance, the engine is very well suited for extreme 3D and towing flights. It can transport a maximum take-off mass of 18 kg when used in aerobatics. Here the engine runs extremely smoothly and quietly with a low level of vibration. Throttle response is very direct, equally so in the medium range.
