The best model engines across every category, hand-selected by our team.
TOYAN FS-L400BGC 14cc Inline-Four
A 14 cc inline four-cylinder, four-stroke petrol engine that you assemble yourself. Rated at 3.05 hp between 3,200 and 13,500 rpm, with CDI ignition, an electric start and combined water and air cooling. The full set includes the starting harness, fuel tank, radiator and a battery, so almost everything you need to run it is in the box apart from the fuel.
TOYAN FS-V800WGPC 28cc V8
Toyan's 28 cc OHV V8 at 1/10 scale is the cheapest genuine gasoline V8 we found at either specialist retailer. Water-cooled, with its own oil-pump lubrication, a brushless starter motor and CDI ignition with a distributor, rated at 3.85 ps between 1,950 and 8,650 rpm. The $1,099 kit is the engine only: the retailer states that ignition, starting and water-cooling parts are bought separately, and sets that include a starter kit and stand cost up to $1,449 as a kit or $1,549 pre-assembled.
TOYAN FS-L200GC 7cc Inline Twin (Petrol)
A 7 cc air-cooled inline twin that runs on petrol, rated at 0.6 PS between 4,000 and 16,000 rpm, with CDI ignition and a built-in electric starting motor. The $229 kit is the engine only; sets with the starter kit start at $329.
