BLDB Launches SEMTO 7cc Inline Twin Engine Assembly Kit
The kit adds an inline twin layout to BLDB's metal engine model series, letting builders assemble and run a working engine rather than display a static replica.

BLDB, the model brand behind the Building Block line, has started selling the SEMTO ENGINE ST-NF2/FS-L200AC, a 7cc inline twin 4-stroke SOHC engine assembly kit. Builders assemble the engine from unassembled parts, then start it on methanol glow fuel with 20 to 25 percent nitromethane. The kit uses dual timing belts, air cooling, and a 480 brush motor electric starter, with CNC-machined anodized aluminum parts. BLDB offers three purchase configurations.
The ST-NF2/FS-L200AC uses a long-stroke design with a 16.6mm bore and 17.0mm stroke per cylinder, rated at 4,000 to 16,000 rpm and 0.6PS. Power reaches the valve train through two timing belts, and starting is handled by a 480 brush motor fed by a 7.4V 2S lithium battery. The engine needs an F-type 4-stroke glow plug and a matching ignition module.
BLDB sells it in three configurations: the engine model alone, with an engine start kit, or with a start kit and base. The company notes the engine is not a toy, recommends it for ages 14 and up, and warns against running it in poorly ventilated rooms.
