Running smoothness and greater engine power

A good choice for aerobatics, towing, or scale models, it impresses with quiet running behaviour thanks to its 3-bearing crankshaft. The engine develops a unique running smoothness with the matching 3W muffler system. It is suitable for a broad variety of models due to the weight-performance ratio and distinguishes itself through its reliability, durability, and power.
The 3W Competition series (CS version) distinguishes itself through greater performance, more rapid response behaviour, and high torque. The engine thereby achieves a high standard of per-formance. Transfer ports in the cylinder and crankcase are modified.
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).
