CDX Blocks is introducing an all-new series of working, interactive, building-block based model kits of classic amusement park rides, to complement our roller coaster models that fans know and love. The CDX Fun Fair Series are building block construction kits based around fairground and carnival style amusement rides. All of the models are engineered to function like their full sized counterparts, with rotating seats, cars, and platforms. Just like our roller coaster models, the Fun Fair rides are very mechanical in operation, with numerous shafts, gears, and gear racks intermingling to create a beautiful symphony of movement.
