 Shipping Notice: this engine is in production now. and it will be sent out at end of April. 

don't miss it. any problem pls contact [email protected]

notice time: March 4, 2026

 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

.Starter Kit: The engine is equipped with an electric motor, providing users with all new fun. Therefore it is started by electricity and does not need to be pulled by hand. To start this engine you need to buy the extra starting accessories, for example refer to glow head, ignition module, etc. (it has 2 versions. you can also buy it from this link below)

Note: TOYAN FS-L400 is now equipped with an upgraded starter motor. As you can see, one end is positive and the other  is negative. It can bed connected by either weldding, or using a plug to connect the 2s T Plug lithium battery with 2 wires from the positive & negative poles of the starting motor. so there is no need to connect the ESC. ( the 4-in-1 Ignition kit doesn't have a push button, so you have to disconnect the battery manually after the engine is started.)

.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.
.For Ages: 10+

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.

3. Connector: There are 4 carburetors but only one fuel line from the fuel tank so 3 connectors are recommended to make the fuel rail right for the L400. You can choose either T shape or Y shape connector if possible.  (see the photo below)

Y type: http://bit.ly/37ho4YJ

T type: http://bit.ly/37kz1st

Upgrade: 4in1 T Fitting (recommend) : http://bit.ly/3smw2YO

4. Battery: TOYAN FS-L400 uses 2s T Plug lithium battery, the same one as that of FS-L200 engine.

5. Fuel: Please use quality guaranteed methanol model engine fuel. Self - dispensing or counterfeit fuel will greatly reduce the performance and life span of the engine. Since it is a four-stroke engine, in order to ensure the normal operation of the engine, we require the only 20-25% nitro methane fuel can be used. If high nitro fuel is used, the ignition time and cylinder pressure of the engine will be greatly affected, and the normal and stable operation cannot be maintained.

When the nitro content of the fuel increases or the brand of fuel change , it is recommended to use oil-rich needle adjustments to run the engine so that the optimal setting for the new fuel can be rechecked, (please adjust the ratio of gasoline fuel to 1:25 to 1:30, and use 2T engine oil).

6. Lubrication: TOYAN FS-L400 has no lubrication system. No need to add oil, just add red grease on the camshaft. The crankshaft and piston connecting rod are lubricated by themselves during operation. The grease will penetrate, and then drain the waste oil from the oil outlet. The crankshaft does not need to be refueled in normal operation, and is lubricated by fuel. When installing parts, moving parts can be mechanically lubricated with two drops of engine oil.

7. Cooling Problem: Try to use non-corrosive liquids, such as water, distilled water, car coolant, computer water coolant and so on. Distilled water is recommended. If not, you can directly use ordinary water, about 180ml.
