Mid-Open Chassis Frame Lightweight Gearbox Base Plate Kit Mounting Screws RC Accessory

This RC accessory is an aluminum chassis frame upgrade for the 1/12 MN300 Tank 300 RC car, made to support a cleaner and stronger build. As an aluminum chassis frame, it uses 6061 aluminum and weighs 150 g, offering a solid metal feel without unnecessary bulk. The mid-open chassis frame features a long rail structure with the center left open, giving the main frame an efficient layout. That design works well when a low-profile, practical chassis structure is preferred for model assembly and maintenance. This gearbox base plate kit includes a matching gearbox base plate and mounting screws, providing the key parts needed for installation. Together, the parts form a coordinated upgrade set that can help refresh the RC vehicle with a more rigid and organized foundation. For builders and hobby users, the frame is suited to upgrade work, replacement use, or custom model refinement. It is a straightforward chassis solution focused on structure, fitment, and dependable support for the RC vehicle.
