3-Meter Aerobatic models? No problem for this engine. With its power out put the 3W-170xiB2 supplies more than enough power for all aerobatic maneuvers. A good choice for models towing lager wing span Sailplanes. The crankshaft with its 3 ball bearings convinces with soft running characteristics.

The suitable 3W-muffler system insures excellent running characteristics. Due to the to its weight to power ratio the engine is suitable for a wide range of models. Long life, reliability and power are its attributes.

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).

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 ).
