TOYAN FS-L400 14cc Inline 4 Cylinder 4 Stroke Nitro Engine Model RTR Assembled
Hero Section: The Symphony of Four Cylinders
There is a distinct difference between a single-cylinder "pop" and the harmonic roar of an inline-four. The TOYAN FS-L400 RTR (Ready-to-Run) brings that automotive symphony to your workbench without the need for complex assembly. This is a fully assembled, 14cc miniature powerhouse that revs to a screaming 13,500 RPM. Whether you are upgrading a 1/8 scale RC chassis or seeking the ultimate kinetic display piece, the FS-L400 offers the most realistic internal combustion experience available in miniature form. (Note: Only 28 units remaining in this batch.)
Why Choose the TOYAN FS-L400 (RTR)?
- Factory Assembled Precision: Skip the hours of complex assembly. This "RTR" version comes professionally assembled and timed by factory technicians. It is ready for the break-in process right out of the box, ensuring you start with a perfectly calibrated machine.
- True Automotive Architecture: This isn't just a toy; it's a scaled-down car engine. Featuring a 180-degree crankshaft and a 1-3-4-2 firing order, it delivers the smooth power delivery and responsive throttle snap of a real sports car engine.
- High-RPM Performance: With a redline of 13,500 RPM and 3.05ps of power, this engine screams. The long-stroke design ensures that high RPMs are matched with significant torque, making it capable of moving heavy RC vehicles with authority.
- The Ultimate Collector's Piece: With its exposed timing belts, four independent carburetors, and mechanical water pump, the FS-L400 is a masterpiece of mechanical art. It is the perfect gift to spark a passion for engineering in a loved one or to crown your own collection.
Technical Highlights: Engineering Deep Dive
- Quad-Carburetor System: Each cylinder has its own independent carburetor. This allows for incredibly precise tuning, ensuring that every cylinder is firing at peak efficiency for maximum power and stability.
- Active Mechanical Cooling: Heat is the enemy of performance. The FS-L400 features a built-in mechanical water pump driven by the crankshaft. This provides active coolant circulation (radiator required), allowing for extended run times without overheating.
- Dual Synchronous Pulleys: To handle the stress of 13,500 RPM, the timing belt system uses a dual-pulley structure. This minimizes the risk of belt slippage or gear jumping, ensuring precise valve timing even under heavy load.
- 180° Crankshaft Design: The single-piece machined crankshaft features a 180-degree design, which is the secret behind the engine's smooth operation and rapid acceleration response compared to flat-plane cranks.

Usage Scenario: The Workbench Test
You unbox the engine, admiring the pre-assembled complexity. You mount it to your test stand and connect the fuel lines to the four carburetors. You hook up the water cooling loop. You press the start button on the electric starter. The motor whirs, and suddenly—VROOOM. The engine settles into a rhythmic, complex idle that sounds like a vintage race car. You blip the throttle, and the four cylinders sing in unison. It’s a visceral mechanical experience that digital screens simply cannot replicate.
Important Tips from the Workshop
- "RTR" Definition: While the engine block is assembled, "Ready to Run" in the hobby world means the engine is ready. To run it, you will still need to provide/connect: Fuel Tank, Fuel Lines, Radiator/Water Tank, and a Battery for the starter motor.
- Fuel Requirement: This engine is tuned for 20-25% Nitro Methanol Fuel. Do not use gasoline.
- Lubrication: The cylinders are lubricated by the fuel, but the camshafts (top of engine) require manual lubrication. Apply red grease to the cams periodically to prevent wear.
- Break-in: Even though it is assembled, the engine requires a break-in period. Run the first few tanks of fuel rich and at moderate RPMs to allow the piston rings to seat properly.
