The 4-Tec 2.0 comes with either a standard TQ radio or the Bluetooth-ready
TQI transmitter, depending on which model you get. The 4-Tec VXL chassis and Ford GT RTR get the TQI, the brushed-power chassis and Mustang GT RTR get the plain TQ. Set aside an extra $30 for the Traxxas Link Bluetooth module, which installs in ten seconds to make your phone or tablet a high-res display and interface for the TQI via the free Traxxas Link app , available for IOS and Android devices. You can choose what to assign to the radio’s Multi-function knob, set sub-trims and endpoints, adjust “sensitivity” (aka exponential), and set steering and throttle rates. Plus, you can manage model memory, operate the Traxxas Drag Timing System, display telemetry data on a virtual dashboard… it’s a powerful system.
46 The Traxxas Link app connects instantly for tap-and-slide adjustability of all the radio’s tuning functions, model memory, telemetry, and more.
The Bluetooth module plugs into the back of the TQI. It’s the best $30 you’ll spend on a 4-Tec (or any other Tqi-equipped model).
The 4-Tec VXL gets Traxxas Stability Management, which comes in very handy when you’re shooting for 70mph. TSM can be dialed up or down or switched off completely right from the radio.
