This is the Traxxas TQi 2.4GHz Radio System with 5-Channel Traxxas Stability Management (TSM) telemetry-enabled receiver and Bluetooth Wireless module included. The Bluetooth wireless module works in conjunction with the Traxxas Link App on Android devices, Apple iPhone, iPad, and iPod Touch.
Traxxas Stability Management
Traxxas Stability Management (TSM) allows you to experience all the extreme power, speed, and acceleration that was engineered into your Traxxas model making it much easier to control on common slippery surfaces such as dusty asphalt, smooth concrete, and even ice and snow. Punch it off the line and TSM goes to work sensing the vehicles direction and making steering corrections to provide straight-ahead full-throttle acceleration without fishtailing, spinouts, and loss of control. TSM also works during cornering, first making intuitive corrections to maintain your line, and then allowing you to hammer the throttle earlier in the turn for much faster exit speeds. Braking is dramatically improved as TSM works to keep you arrow straight until you come to a complete stop.

Prepare to unlock the full potential of the TQi 2.4GHz radio system through the Traxxas Link Wireless Module.
High Output Signal For Maximum Range
Top-level performance is what you expect from Traxxas, so the TQi 2.4GHz transmitter pumps out a strong, clear signal for optimum range. The 13ms frame rate and near zero latency results in instant steering and throttle response with precise, smooth control. TQi features an internal antenna, so there are no visual obstructions or external devices to break off.
Simple 2-Button Interface
All of the TQi 2.4GHz radio system's advanced functions are selected and adjusted using a simple 2-button interface. MENU and SET are all you need to navigate to the functions you wish to adjust, and the Status LED confirms each selection. Traxxas' advanced electronics give experienced drivers pro-level adjustability, without compromising simple operation when it's time to play and have fun.
The Multi-Function knob is key to the transmitter's adjustability. By using the MENU and SET buttons or the Traxxas Link App, a variety or performance parameters can be assigned to the Multi-Function knob for easy, on-the-fly adjustment. From the factory, the Multi-Function knob controls steering sensitivity, also known as exponential or "expo." The Multi-Function knob can also be set to control Throttle Sensitivity (Expo), Steering Percentage (Dual Rate), Braking Percentage (Dual Rate), and Throttle Trim. The Multi-Function knob can also be locked to prevent unwanted setting changes.
5-channel Micro Receiver with Fail-Safe Security
The TQi 2.4GHz micro receiver fits easily into any vehicle, and features dual channel-1 outputs for easy installation in vehicles with dual steering servos - no Y-harness necessary! The integrated LINK button makes it fast and easy to bind the receiver, and the two-color LED indicates power-on and bind status for fool-proof control and convenience. Traxxas Link Model Memory allows the receiver to recognize up to thirty TQi 2.4GHz Traxxas Link enabled transmitters - just switch on and drive. In the event of signal loss due to an accidental switch-off or depleted batteries, the receiver will automatically return the throttle to neutral and hold the last commanded steering position. The Fail Safe programming is built-in and does not need to be set or activated. Three telemetry ports are incorporated in the 5-channel receiver to allow real-time data to be transmitted from your Traxxas model to the TQi transmitter.
Plug-In Telemetry Sensors and Expander Module Available
TQi makes it easy to add telemetry capability to any Traxxas model when you equip the transmitter with the Traxxas Link Wireless Module and install Traxxas Link on your iOS device. TQi's included 5-channel receiver features ports for Voltage/Temperature and RPM sensors. A third port accepts the Telemetry Expander Module that allows up to 6 additional sensors to be added. There's even a GPS Module for satellite-measured speed (sensors, expander, and GPS module each sold separately). Sensor-ready gear covers or motor mounts custom-fit for your Traxxas vehicle install easily to precisely position the sensors for accurate detection of the "trigger magnets" built into the spur gear or flywheel required for your model. Just install the telemetry components and you're ready to go! The Traxxas Link application automatically detects the sensors installed in the receiver. Go to Telemetry Setup in the Traxxas Link application and touch Sync Now, and TQi automatically detects the sensors installed in the Expander Module. Only Traxxas makes telemetry so easy to install, view, and enjoy.
Steering and Throttle Sensitivity (Expo)
The TQi 2.4GHz transmitter's Multi-Function knob can be programmed to control Steering and Throttle Sensitivity, also known as exponential. This is a powerful tuning aid that can help tame a "loose" track, improve throttle control, and help you turn faster, more consistent laps. When set for minimum sensitivity (zero exponential), steering or throttle response is linear: the steering or throttle response will correspond exactly with the input from the transmitter's steering wheel. Turning the Multi-Function knob clockwise will result in "negative exponential" and decrease steering or throttle sensitivity by making the servo less responsive near neutral, with increasing sensitivity as the servo nears the limits of its travel range. The farther you turn the knob, the more pronounced the change in steering servo movement will be. The term "exponential" comes from this effect; the servo's travel changes exponentially relative to the input from the steering wheel. The exponential effect is indicated as a percentage - the greater the percentage, the greater the effect.
Steering and Braking Dual Rate
The Multi-Function knob can be set to control the amount (percentage) of servo travel applied to steering. Turning the Multi-Function knob fully clockwise will deliver maximum steering throw; turning the knob counter-clockwise reduces steering throw. Many racers set Dual Rate so they have only as much steering throw as they need for the track's tightest turn, thus making the vehicle easier to drive throughout the rest of the course. Reducing steering throw can also be useful in making a vehicle easier to control on high-traction surfaces, and limiting steering output for oval racing where large amounts of steering travel are not required.
The Multi-Function knob may also be set to control the amount of brake travel applied by the servo in a nitro-powered model. Electric models do not have a servo-operated brake, but the Braking Percentage function still operates the same way in electric models. Turning the Multi-Function knob full clockwise will deliver maximum brake throw; turning the knob counter-clockwise reduces brake throw. This is a very useful feature for preventing spin-outs due to brake lock-up on slick tracks; just dial out unwanted brake travel for more precise control.
Steering and Throttle End Points
The TQi 2.4GHz transmitter allows you to choose the limit of the servo's travel range (or its "end point") independently for left and right travel (on the steering channel) and throttle/brake travel (on the throttle channel). This allows you to fine-tune the servo settings to prevent binding caused by the servo moving steering or throttle linkages (in the case of a nitro car) farther than their mechanical limits. The end point adjustment settings you select will represent what you wish to be the servo's maximum travel; the Steering Percentage or Braking Percentage functions will not override the End Point settings.
Steering and Throttle Sub-Trim
The Sub-Trim function is used to precisely set the neutral point of the steering or throttle servo in the event that simply setting the trim knob to "zero" does not completely center the servo. When selected, Sub-Trim allows finer adjustment to the servo output shaft's position for precise setting of the neutral point. This is particularly useful for high-speed vehicles such as the Nitro 4-Tec 3.3, Jato 3.3, and VXL/Castle brushless models that require laser-straight tracking when the steering wheel is at
