Rugged single-cylinder engine The engine is very well suited for 3D flight as well as for flight models XTRA/230 and VOTEC/230 – FUNS or another Funflyer with a model mass of up to 9 kg. The engine is moreover a good choice for towing or scale models. It impresses with quiet running behaviour thanks to its 3-bearing crank-shaft. Due to the matched 3W muffler system, the engine is comparable to other manufacturers’ 70 ccm engines because the performance data are analogous. The engine is suitable for a wide variety of models and distinguishes itself through its reliability and durability. 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).
