The 6533 TSM receiver is a replacement 5 channel receiver designed for Traxxas RC vehicles equipped with Traxxas Stability Management technology. This receiver works with Traxxas TQi transmitters to provide precise control, smooth steering response, and improved vehicle stability on loose surfaces and at high speeds. The built in TSM system helps maintain traction and control by automatically making small steering corrections while you drive. It features a compact waterproof design that is built to handle off road conditions, dirt, and moisture. The 6533 receiver is compatible with Traxxas models that use the TQi radio system and TSM technology, including vehicles such as the Traxxas Slash 4x4, Rustler 4x4, Stampede 4x4, Hoss 4x4 VXL, and Maxx.
