All six wheels have active suspension system. Each system is made of approximately 25 parts. They are uniquely numbered so keep a close eye during construction!
A pleasant kit to build, this is my second RPG Model that I've built so far. The detail, molding and fit is great. You get six rubber tires and a sizeable photo-etch plate as a very detailed instruction sheet. All wheels have an active suspension system, but the construction of the suspension is complex and require a lot of focus from the modeler's side. I summed up my construction highlights in this video. Youtube Video
