Features:.Toyan has a passion for machining the highest precision and quality scale engine models. Toyan indeed has released a few engines in assembly DIY versions. However, we find some students can't afford it even though they do like Toyan engines but not the price. So we discuss this with the Toyan engine team. Why not make an engine that everyone can afford? We hope every petrolhead college student can take it even if they have a low budget. In this case, the idea of making an entry-level come into Toyan mechanics' minds for a year. So they have started to design and make it several times. And they have also co-branded with SEMTO Engine & OTTO MOTOR to make brand-new 2-cylinder 4-stroke engine kits recently. That means the costs are greatly marked down.  so that is, OTTO MOTOR FS-L200AC ( or SEMTO ENGINE ST-NF2) - Simple, Easy To Use, and Intuitive.
