Top Features of the FS-L200W

Advanced Water-Cooling System

The FS-L200W uses an upgraded water-cooling groove that prevents overheating during long or high-speed operation. When paired with a cooling fan, the self-cooling performance increases dramatically.

Upgraded Extended Crankshaft

The extended crankshaft is engineered to support forward and reverse gearboxes, making this engine ideal for RC models that require dynamic movement and versatile power output.

Asynchronous Crankshaft System

This design allows:

Higher maximum RPM (up to 16,000!)
Smoother engine operation
Faster and more responsive acceleration

It’s a game-changer for RC fans who prioritize speed and precision.

Adjustable Belt Pulley

The adjustable pulley system:

Reduces tooth skipping
Ensures smooth high-speed performance
Supports a large gear ratio starting pulley

Combined with a high-torque brushless motor, starting the engine is calm, smooth, and dependable.

Additional Structural Upgrades

Long Stroke Design

Provides improved torque output—especially useful for RC trucks, boats, and heavy-load applications.

Lightweight Construction

The engine’s lightweight structure improves the power-to-weight ratio, making RC vehicles faster and more efficient.
