This is the Crawler Pro Kit model from the RGT brand. Based on the Rock Cruiser 1:10 4wd, the brand offers this model with an improved chassis and other parts, but it is not Ready-To-Run, so it requires all the electronics.
Both the chassis rail and the battery holder are made with carbon fibre to increase performance. In addition, to improve performance and increase stiffness, the vehicle features high-strength 6061 T6 aluminium alloy on the chassis and many other parts to increase weight, performance, and durability.
Note: This kit requires electronics
