This is a limited edition option part for the FS-12FZ glow engine, which is used in the new release for Item 84390 TG10-Mk.2FZ Chassis Kit.
Made from lightweight aluminum, the flywheel represents a weight saving of around 15g compared to kit standard sintered part. The weight reduction gives more efficient engine rotation response. Comes in a blue anodized finish. Compatible with TG10-Mk.2FX and TG10-Mk.2FZ cars.
