Difference of This L400WC VS L400 engine: The internal struture and cost has been improved,all parameters are same Description: Basic information Brand:TOYAN Item No:FS-L400WC Color:As color shown Speed:3200-13500 RPM Power System Displacement:14cc 锛?.5cc x 4) Power:3.05ps Other Parameters Engine Weight:980 (No Electric Starter Kit) Package Weight:1500g Dimension Engine Size:121.05 x 43.67 x 90.00mm Piston Diameter:16.60mm Stroke:17.00mm Package Dimensions:20 x 15 x 15cm Other Required Parts:(not included) 1.Methanol;2.Glow plug,3.ignintion module;4.7.4v Li and 11.1v Li battery Note:The engine needs to assemble by yourselfThe glue and oil are not includedThe extra starter kit and radiator and the base are also not included Features: -High Simulation: The red sport element design and the highly simulated appearance are much closer to the real engine-Long Stroke: Take the long stroke as the engine design blueprint, effectively provide higher torque-Integrated Crankshaft: With a 180掳crankshaft structure, the 1342 ignition turn runs more smoothly and the acceleration response is more sensitive. The maximum speed is about 13500rpm-Double Synchronous Pulley: The timing structure of dual synchronous pulleys greatly reduces the risk of tooth skipping in high-speed operate-Precision Rocker: Alloy rocker arm, independent intake and exhaust design, more precise valve switch -Built-in Mechanical Pump Water Cooling Jacket: The power of the pump body comes from the crankshaft, which provides circulating power for the coolant, and then cooperates with the cooling fan to enhance the self-cooling performance-Precision Carburetor: The new independent four-carburetor design allows players to have more precise adjustments, making the throttle response more sensitive and working more stable-High Precision Gear Pump: High-speed structure design, corrosion-resistant material manufacturing, large flow pump water, provide powerful cooling capacity-Lightweight Design: Lightweight structural design, can be better compatible with RC models, greatly improve the unit power output ratio-DIY: High-precision parts manufacturing, stable assembly effect, integrated electric start, provide you with brand-new fun Package Included:1X TOYAN L400WC Engine KIT Important Notice: (Please read it before you start to build this engine) 1. Piston Rings: Our team has assembled the piston rings in the block in advance because it's very difficult to do it for the average people. pls follow the instruction to build it and you will find out the piston is already inside the cylinder liner. they are not missing. 2. Glow Plugs: The glow plugs isn't powered all the time when the engine is running, and they're only powered during engine startup and disconnected battery after the engine has started. <p class
