RC rock crawlers are designed for running on rough terrain and to climb over rocks and obstacles, making them perfect for off-road driving. An RC rock crawler may be slower than the typical RC car, but that feature makes them more useful and stable on tougher when driving over impossible obstacles like rocky hills and trails or obstacle courses. You can purchase a hobby-grade RC rock crawler online at a reasonable price if you are new to crawler racing.
Rock crawler RCs are battery powered electric trucks with special wheels, electronic speed controls, specialized differentials, and extremely flexible suspensions. Their electronic speed controls must be optimized for crawling over challenging obstacles. You can find them in different scales, like 1/10 and 1/8. RC rock crawlers may appeal to you if you want to run a powerful RC vehicle with more torque and a lower gear setup to achieve a steady power at low speeds. These qualities enable the crawlers to climb and drive over rocks and tough obstacles without toppling over.
1/8 scale RC rock crawlers come with four-wheel steering and dual motors to ensure the best crawling capability. 1/10 scale RC rock crawlers are smaller, but nevertheless powerful. Some of the best 1/10 scale RC rock crawlers come with twin locker differentials, axle mounted 15Kg torque steering servo, a fully installed two-channel 2.4G pistol grip radio, oil filled alloy cap shocks, and full ball bearings. There are 4 wheel steering units, available also.
