A working 3.5cc four-stroke sold as a tabletop kit moves the metal model hobby from display pieces toward small machines the buyer has to fuel, cool and tune before they turn over.

BLDB, the metal model store run by Shuei Network Trading, has begun selling CISON's L100, a 3.5cc evaporative-cooled single-cylinder four-stroke gasoline engine model at roughly 1/8 scale, with a release date of October 12, 2026. It runs on fuel and ignites with a spark plug, so the intake, compression, combustion and exhaust strokes can be watched on a desk. Bore is 16.6mm and stroke 17mm, with a dual balancer, adjustable carburetor and belt-driven pulley output.
The L100 is built around a horizontal single-cylinder layout that recalls an old stationary engine, shrunk to a handheld size at about 1/8 scale. A blue cooling tank, a red cylinder head, and exposed flywheel and piping make the construction readable before it ever runs, and the metal assembly stands on its own as a display piece.
Cooling is evaporative, shedding heat as the cooling water evaporates during operation. A dual balancer counters the vibration that comes with a single cylinder, the carburetor can be adjusted to conditions, and a pulley output drives external mechanisms by belt. Buyers are expected to check cooling water, fuel and ignition before each start.
