Features, Architecture & Package Contents

 FS-L400  Inline Four-cylinder Four-stroke Engine ModelAssembly Kit

 Features:

.Exquisite Model: Incredibly detailed following the real engine.

.Long Stroke: Long-stroke for effectively higher torque.

.Integrated Crank Shaft: It utilizes a 180-degree crankshaft. The ignition timing sequence of 1342 for running smoother and more sensitive acceleration response. The maximum speed is 13,500 RPM.

.Double Synchronous Pulley: The timing structure of the dual synchronous pulley reduces the risk of gear jumping during high-speed operation.

.Precision Rocker Arm: Alloy rocker arm and independent intake and exhaust design for more accurate valve switch.

.Built-in Mechanical Pump Water-Cooled Kit: The power of the pump body comes from the crankshaft, and the pump body provides circulating power to the coolant. Later, it can cooperate with the cooling fan to enhance the self-cooling performance

.Precision Carburetor: Independent four carburetors for more accurate tuning, more sensitive throttle response, and working more stable

.High Precision Gear Pump: High-speed structure design & corrosion-resistant material manufacturing. Large flow water pump provides powerful cooling capacity.

.Lightweight:  It can be better compatible with the RC model and improve the unit power output ratio

.DIY Assembly: This engine features exquisite appearance, superior quality, excellent craft, and strong practicability. You can either enjoy the fun of DIY assembly, build your engine work and collect the finished product as a static decoration, or start the engine, or modify it to an RC model. We believe you will love the model engine. More applications are waiting for you to develop. I'm sure you'll like this engine model. Suitable for personal use or as a high-end model gift to others.
