Taking you, my german shepherd (king shepherd) and my TRX4 Sport for a walk on the rocks! Our blue Traxxas TRX4 Sport All Terrain has RC LED lights, the HobbyWing XeRun Sensored Brushless ESC/Motor system, a Traxxas Long Arm Lift Kit, Hot Racing Steel Spur Gear 45 Tooth (CNC machined and hardened steel construction) and Traxxas 10 tooth Pinion Gear. One of my favorite RC crawlers, no matter what you call it – a RC 4×4 scale action remote controlled car, scale crawler, RC crawler, RC truck. People call the Traxxas TRX-4 Sport different things, like Traxxas TRX4, Traxxas TRX-4, TRX-4 Sport, TRX4 Sport, Traxxas TRX 4, TRX-4, TRX 4, TRX4, Traxxas TRX-4 Sport, RC crawler, TRX 4 crawler, Traxxas Crawler, TRX-4 All Terrain rock crawler, 1/10 scale, RC 4×4 – same thing. Traxxas, it is the fastest name in radio control – traction & Traxxas!
