RC Rock Crawlers And Trail Trucks

What is an RC rock crawler?
An RC rock crawler is a remote-controlled vehicle built for slow, controlled driving over rough terrain. They use four-wheel drive, soft tires, and flexible suspension to climb rocks, clear obstacles, and handle uneven ground where speed isn't the goal. Many crawlers are modeled after real 4x4 trucks and SUVs.

How do you make an RC rock crawler faster?
One way to increase speed is by changing the pinion gear, which connects directly to the motor. Adding a gear with more teeth increases top speed but may reduce low-speed torque, making the crawler less precise on steep climbs. It’s a balance between speed and crawling control, so choose based on the type of driving you plan to do.

How fast do Traxxas crawlers go?
Most Traxxas rock crawlers are designed for control, not speed, with top speeds around 20 km/h. This slow pace lets them climb rocks and navigate tough terrain without losing grip or tipping over. If you want to go faster, look at Traxxas’ trail trucks or adjust your crawler’s gearing and motor setup.
