feature: The building block desert racing car is assembled from more than 490 building block parts, and has the dual characteristics of building blocks and desert racing. Under the shape of a dedicated desert racing car assembled from small building blocks, there is also a complex mechanical transmission structure hidden. The internal gears cooperate with each other to form the pure mechanical transmission control system of the desert racing car. The building block desert racing car adopts a rear-mounted simulation engine device and a cylinder-piston linkage system assembled by building blocks. While the desert racing is in motion, the cylinder and piston will also move along with it, simulating the real car. The internal structure of a car engine. The simulated body, the desert racing car also simulates the suspension system of the real car, and the imitation of four independent suspension shock absorbers can fully absorb the vibration of the bumpy road. And each wheel can move independently, improving the stability of the car. As one of the milestones of automobile development, "Ackerman Steering" has undoubtedly made modern automobile steering progress. The building block desert racing car also adopts this structure. The design of the big tail can not only guarantee our driving safety, but also make the desert racing have a whole. The building block desert racer is equipped with four tires, and the diameter of the rear wheel is significantly larger than that of the front wheel, which makes it better able to cope with various terrains. The front and both sides of the car body are designed with bumpers, which not only have decorative functions, but also absorb and mitigate external impact forces, and effectively protect the safety of the car body. Building blocks Desert racing cars are made of non-polluting and safe raw materials, so you can safely let children build building blocks.
