3W-110 iR2 CS


The 2 inline cylinder arrangement and ist 5 ball bearings ensure a smooth running characteristic. Vibrations are minimized and help to extend the life time of the model and onboard electronic. Due to the alternative firing of the cylinder ,the noise level is low. The sound cannot be compared with a 2-cylinder boxer engine. Baffling of the engine is mandatory to avoid over heating and damage of the engine. Engine can be used for a wide range of models. Characteristics are its long life, reliability and power.

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 ).
