Suitable for 3D-flying for models with a maximum take off weight of 9,0 kg. A good choice for Scale Models or for towing Sailplanes. The crankshaft with its 3 ball bearings ensures proper running characteristics.

With a suitable 3W-Muffler system a power out put is possible which can be compared with engines of 70 ccm of other manufactures. The engine can be used for a wide range of models. Characteristics are its long life and reliability.

3W-CS-Serie ( Competition Series ) is characterized by better performance, throttle response and more power and torque. Selected parts are used for these engines. This results in a higher performance level. Transfer ports of the cylinder and crankcase are modified as well as the exhaust port.

The micro processor controlled igniton allows to easy start  the engine. The programmed timing curve is laid out for the engines and guarantees a good running characteristic in all RPM – ranges. An out put signal to monitor RPM is standard as well as a LED showing the status of the ignition. The voltage range of the standard ignition : 6V – 8,4V ( 2 cell LIPO battery ).
