3W-28i Engine 3.4 HP Power

Manual Video Spare Parts High-performance single-cylinder engine The small, single-cylinder engine is suitable for 3D flight for the XTRA and VOTEC – FUNS models as well as for all other Funflyers up to 6 kg model mass. A static thrust of up to 8 kg can be achieved with suitable propellers. Thus it is appropriate for a wide variety of models. The enormous power development makes it comparable to other engines with larger displacements. 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).
