The robustness of 3W-275xiB2 leaves nothing to be desired. The generously dimensioned ball bearings and needle bearings as well as the strong crankshaft insures a long life time of the engine. This make it interesting for industrial use. With a suitable 3W-muffler system and propeller a static thrust of 55kg can be achived. The engine can be used for a wide range of models.Its characteristics are : reliability, power and a long life.

TS –Version ( Twin Spark , 2 spark plugs per cylinder ) convinces with a low idle and softer running characteristic.  All boxer engines with this set up have a better reliability. In case 1 ignition will fail the 2^nd. ignition - which operates autonomously – allows the engine to run further with reduced RPM ( 200 – 300 ).

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 ).
