The engine is ideal for the 3 metre aerobatics class. With sufficient performance, the 3W-170Xi B2 provides enough power for all figures. It can be deployed without hesitation even for towing large models. It impresses with quiet running behaviour thanks to its 3-bearing crankshaft.
The engine develops a unique running smoothness with the matched 3W muffler system. It is suit-able for a broad variety of models due to the weight-performance ratio and distinguishes itself through its reliability, durability, and power.
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).
