A good choice for : Aerobatic models, Scale models or airplane models for towing Sailplanes. The crankshaft with its 3 ball bearings convinces with soft running characteristics. With a suitable 3W-muffler system the engine shows out standing running characteristics. Due to its weight to power ratio the engine is suitable for a wide range of airplane models. Characteristics are its long life , power 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 ).
