Overview

TQ 2.4GHz - The Next Generation of Traxxas 2.4GHz Technology

Traxxas introduces the next generation of 2.4GHz radio system performance and it's available now in the new Traxxas Slash 4X4. The new Traxxas TQ 2.4GHz computerized High Output radio systems are equipped with superior Direct Sequence Spread-Spectrum (DSSS) technology, fully programmable features, and the convenience of patent-pending Traxxas Link automatic model recognition. Forget about crystals and frequency conflicts! The transmitter's easy-to-use design provides the instant, worry-free, turn-it-on-and-go driving fun you expect from Traxxas, while also delivering a full compliment of pro-level tuning features for those who wish to explore the expanded tuning possibilities. The Multi-Function knob on the face of the transmitter can be programmed to control a variety of functions such as steering exponential, steering and braking dual rate, and throttle trim. Access is through a simple menu tree controlled by a two-button interface. Other tuning options include end point adjustment, servo reversing, and sub trim adjustment. Top-level performance is what you expect from Traxxas, so the new TQ 2.4GHz High Output pumps out a strong, clear signal for optimum range. The 13ms frame rate and near zero latency results in instant steering and throttle response along with precise, smooth control.

The exclusive Traxxas Link automatic model recognition software is a breakthrough in "model memory" that makes it easier than ever to enjoy multiple Traxxas Link enabled models without juggling transmitters or scrolling through complex menus searching for model names. Each time the transmitter is bound to a new receiver, it saves that receiver in its memory, along with all the model settings assigned to that receiver. The next time that transmitter and any previously bound receiver (up to 20!) are switched on, the transmitter automatically recalls the settings for that receiver. Just power up the transmitter and the model you want to drive, and the settings for that model are dialed in immediately! Up to 20 Traxxas Link enabled receivers and 20 Traxxas TQ 2.4GHz High Output transmitters can be cross bound together making it possible to grab ANY transmitter and ANY vehicle from the group, switch them on, and start driving. It's perfect for when you have lots of vehicles you want to drive but don't want to have to keep up with which transmitter belongs to which model. Traxxas Link does it for you, seamlessly behind the scenes.

Details

Ergonomic Design

The unique TQ design features precise balance and a natural feel, with an ample grip area and molded-in thumb rest for total comfort, even during all-day driving sessions. The throttle trigger can be set for 50/50 or 70/30 throw, and the wide trigger gives comfortable, precise control. The four-channel transmitter features a rocker switch placed for easy thumb access, and a 3-position switch positioned next to the wheel for fingertip control. The new TQ 2.4GHz uses just four AA batteries, saving weight and money.

High Output Signal For Maximum Range

Top-level performance is what you expect from Traxxas, so the new TQ 2.4GHz High Output 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.

Simple 2-Button Interface

All of the new TQ 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.

Multi-Function Knob

The Multi-Function knob is key to the transmitter's adjustability. By using the MENU and SET buttons, a variety or performance parameters can be assigned to the Multi-Function knob for easy, on-the-fly adjustment without need for an LCD screen. 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.

Steering and Throttle Sensitivity (Expo)

The TQ2.4GHz 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 TQ 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 brushless models that require laser-straight tracking when the steering wheel is at neutral.

5-channel Micro Receiver with Fail-Safe Security

The TQ 2.4GHz High Output's 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 allows the receiver to recognize up to twenty TQ 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.

Operates On Just 4 AA Batteries

The TQ 2.4GHz High Output requires only four AA alkaline batteries to deliver premium long-range control. That saves money, and reduces the weight of the transmitter for all-day driving comfort.

Lifetime Electronics Warranty

The TQ 2.4GHz High Output radio system, like all Traxxas electronics, features the extra peace-of-mind of our exclusive Lifetime Electronics Warranty. After the expiration of the standard 30-day warranty, Traxxas will repair or replace damaged electronics for a low flat-rate fee, no questions asked. It's Traxxas support you can count on to maintain top performance.

Features

Traxxas Link Features

The new TQ 2.4GHz transmitter is the first to offer a true memory system that doesn't require the user to keep track of model names or numbers. Each time the transmitter is bound to a new Traxxas Link-enabled receiver, it saves that receiver in its memory along with all the settings assigned to that receiver. When the transmitter and any bound receiver are switched on, the transmitter automatically recalls the settings for that receiver. There is no need to manually select your vehicle from a list of model memory entries. Just switch on the transmitter and the model you want to drive, and the settings for that model are dialed in automatically. The transmitter can store settings for up to 20 models!

If the generous 20-model memory isn't enough for your super-sized R/C collection, binding additional Traxxas Link-enabled receivers to the transmitter is no problem; Traxxas Link's smart software will overwrite the model-memory for the model that has been unused the longest. Any of the model-memories can be "locked," preventing the Traxxas Link from over-writing the memory.
