Overview
XRT: Brushless Electric Race Truck with TQi™ Traxxas Link™ Enabled 2.4GHz Radio System, Velineon® VXL-8s brushless ESC (fwd/rev), and Traxxas Stability Management (TSM)®
The Traxxas XRT® fuses race-inspired design and engineering with X-Maxx® power and strength. The result is an extreme platform with sharp reflexes and unprecedented stability that is capable of exploiting the upper range of extreme 8s power and speed.
XRT is engineered with a focus on speed, handling, and performance. XRT's low center of gravity, ultra-wide stance and low-profile body deliver confidence and control as XRT accelerates across the wide-open spaces to an all-out speed of 60+ mph.
XRT performance and durability begins with its all-metal 8s driveline. Steel 4-gear differentials and steel driveshafts are joined by a high-strength extruded aluminum center shaft. It's a precision-engineered recipe that has been proven monster-truck tough in the X-Maxx.
XRT's performance-focused chassis design is configured to lower the center of gravity for superior handling and stability. The dual 6700 4s batteries and the steering servo are positioned to place the weight as low as possible in the chassis and provide protection for these critical components.
