Crawler 4x4 built under the rules of the forthcoming Off-road trial competition in Moscow, at the same time. I tried to build the chassis in such a way as to achieve maximum throughput and maximum flexibility - namely, so this chassis can set the wheels of virtually any size from 62 to 108 mm. The body of the model removable. This allows the chassis to this every body, even though the truck, even an SUV.
