Features 1、Excellent Workmanship: The FS L200w engine is made of aluminum alloy CNC, and the temperature coefficient is more stable. The compact and lightweight structure and multi modular design provide better guard for subsequent upgrades. 2、Strong Performance: The asynchronous crankshaft structure is adopted, the operating is more stable, the acceleration response is sensitive, and the maximum speed is 16,000 rpm. Displacement is 7.0cc (2x3.5cc), output power is 0.82ps. 3、Short Rocker Arm and Extended Crankshaft: Short rocker arm design makes valve switching more accurate. Extended crankshaft design can be matched with front or reverse transmission, suitable for RC model loading. 4、Water Cooling Box and Pulley: Add a new water cooling box to reduce the risk of engine overheating. Large gear ratio starting pulley, with high torsion brushless motor, start more smoothly. 5、Carburetor Design: The new carburetor design, allows players to have more adjustment space, making the throttle response more sensitive and the work more stable.
