Rugged engine as a twin spark (TS) version

The 3W-210i B2 TS’s ruggedness leaves nothing to be desired. With the generously dimensioned ball and needle bearings, as well as the reinforced crankshaft, the engine has a very long service life.
A static thrust of up to 42 kg can be achieved with the matched 3W muffler system. The engine is thus suitable for a broad variety of models and distinguishes itself through its reliability, durability, and power.
The TS version (twin spark) impresses with a lower idle and quieter running behaviour. In addition, the boxer engines obtain even greater reliability this way. When one ignition fails, the second one working independently ensures that the engine continues to run.
The microprocessor-controlled ignition enables simple engine control. The programmed ignition curve is exactly matched to the engines and guarantees good running characteristics in all rotation-al-speed ranges. The standard ignition can be operated with a voltage of 6 V up to 8.4 V (2-cell LiPo).
