About this product

CDX BLOCKS Sidewinder Roller Coaster Building Set is a 848-piece brick construction toy designed for ages 14 and up. This compact model features a gravity-powered roller coaster with a looping track, modeled after contemporary steel coasters. It includes a gear and chain system that simulates the climb to the first hill, followed by a smooth descent through twists and turns. The set uses high-quality plastic bricks and precision-machined metal wheels on the train. Assembly requires no tools and operates mechanically via a crank and gear shaft.
