The TQi (Top Qualifier interactive) is Traxxas' premium pistol-grip radio system. It shares the same comfortable ergonomic form factor across 2, 3, and 4-channel variants, with an internal antenna that is impervious to damage.

Key TQi features: long-range 2.4 GHz signal, automatic model recognition for up to 30 Traxxas Link-enabled vehicles (settings recalled instantly), and full programmability. The TQi is "wireless-ready": install the 6511 Bluetooth Wireless Module (sold separately, or included in some bundles) and the free Traxxas Link app unlocks fine-tuning, LED lighting controls, inclinometer, and real-time telemetry.

The TQi is available in 2-channel (steering + throttle), 3-channel (+ one accessory channel), and 4-channel (+ two accessory channels). Some bundles include the 6511 wireless module and/or the 6533X 5-channel receiver with built-in TSM.
