| This is a four stroke engine whose exhaust note matches scale models.
Quick response and torque feeling of four stroke engine suit aerobatic and sport models too. Mounting bolt pattern is the same as O.S. GT33 and it is easily installed in theexisting models. (The distance between mounts and drive hub face is the same as the GT33.) The same fuel for two stroke engine can be used. (oil mix ratio 25:1 ~50:1) New special carburetor has been developed in collaboration with Walbro. New compact and light weight special ignition module has been developed. Convenient choke rod guide is integrated with backplate. PCV (Positive Crankcase Ventilation) system is employed, which prevents model and environment getting dirty without emitting blow-by gas and oil waste. |
