CDX Blocks was established by a creative and enthusiastic team of designers, including a real roller coaster engineer. CDX Blocks Roller Coaster models are building block construction kits that let you build a roller coaster that really works, and that you can run over and over again. Just like the real thing, once the car reaches the top of the initial hill, it is designed to traverse the whole track back to the starting point, using gravity and potential energy in the most fun way possible. All of our roller coaster models are very mechanical in operation, with a gear shaft and crank to create that thrilling sense of the initial hill climb, and a unique smoothly operating track system for the downhill and thrills to follow. The Cyclone is our first and the flagship kit in the CDX Blocks Roller Coaster Line. The classic lines of a nostalgic wooden roller coaster are beautifully represented with this model. A long and suspenseful initial hill climb leads to the wild ride with the wild dips and turn you expect from a great old-fashioned wooden coaster. Fun to build and even more fun to play with, the Cyclone is an exciting and dynamic ride. At CDX Blocks, the emphasis is on PLAY. Our Roller Coaster models possess a high degree of playability and interaction after the build that our customers love. Visit our Store Page to learn more.
