CoasterDynamix is a United States manufacturer of realistic roller coaster models. Modeling kits are available in both O(1:48) and HO (1:87) scales. The company currently has 4 modeling kits; two designs in O scale based on Bolliger & Mabillard's inverted roller coaster and a traditional wooden roller coaster along with two designs in HO scale.
All kits are fully functional and most allow complete customization. Beginning in 2007, Statix coaster trains were made available for the O scale inverted kits. Statix models feature fully detailed trains with a section of display track to match various coaster types such as B&M hyper, dive and floorless.There are also non-functional Intamin & wood coaster Statix. These are available at a few theme parks, in addition to the company's online store. Released in 2011, the new O scale Comet and Big Dipper feature custom trains, wood structures, and the ability to customize. However, they are expensive. The new trains can run on any non-inverting track if you want a 2 rider per row coaster.
