Build a real, running 14cc inline-four gasoline engine, and get everything it needs to start in the same box. This complete set pairs the TOYAN FS-L400BGC engine kit with its matching one-key start base, so you can go from unboxing to the first start without hunting for a single extra part.
Every part in the base set is made for the FS-L400BGC. No compatibility research, no ordering the wrong igniter or radiator.
Ignition, spark plugs, water cooling, battery and charger are all included. You won't finish the build and then wait for a second order to arrive.
The base has a built-in power switch and start button. No holding wires to the battery or unplugging leads by hand after the engine fires.
Fuel tank, water tank, radiator and wiring all mount neatly on one base, so your engine looks complete on the desk or shelf, running or not.
Costs less than buying the engine and starter base separately, and it all comes in one shipment.
Follow our wiring and start-up guides written for this exact set, and contact our team anytime you get stuck.
Since 2020, the TOYAN FS-L400 has been the inline-four that got many hobbyists into running model engines. The FS-L400BGC is its gasoline version: the same compact 14cc four-cylinder layout, now with CDI spark ignition and running on regular 92# gasoline.
Inside, four pistons, an overhead camshaft and a 90-degree phased crankshaft work together just like a full-size car engine, revving up to 13,500 rpm. A crankshaft-driven water pump circulates coolant to keep it cool on longer runs. You assemble it yourself from precision-machined metal parts, so by the time it starts, you understand exactly how every part inside it works.
