THE TRAXXAS TQ RADIO SYSTEM XL-2.5 Wiring Diagram Your model is equipped with the Traxxas TQ Radio System is a 2-channel system that provides high-power output up to a quarter mile. Your model uses one steering servo and an electronic speed control. The receiver is equipped with four channels and dual channel 1 outputs.
THE TRAXXAS TQ RADIO SYSTEM RADIO SYSTEM TERMINOLOGY Please take a moment to familiarize yourself with these radio and power system terms. They will be used throughout this manual. BEC (Battery Eliminator Circuit) - The BEC can either be in the receiver or in the ESC. This circuit allows the receiver and servos to be powered by the main battery pack in an electric model. This eliminates the need to carry a separate pack of 4 AA batteries to power the radio equipment.
THE TRAXXAS TQ RADIO SYSTEM INSTALLING TRANSMITTER BATTERIES If the power indicator doesn’t light red, check the polarity of the batteries. Check rechargeable batteries for a full charge. Your TQ transmitter uses 8 AA batteries (see sidebar, page 11). The battery compartment is located in the base of the transmitter. Don’t shorten the length of the antenna wire. Its length is tuned to the frequency band; cutting it could severely shorten the radio system’s range.
THE TRAXXAS TQ RADIO SYSTEM INSTALLING BATTERY PACK Your model includes a 7.2-volt battery pack. To properly balance the model, it should be installed in the battery compartment on the left side of the model. Follow these steps to install the battery: Battery Installation 1. Open the battery compartment door by pressing on the release tabs. Battery Wire Slot 2. Install the battery pack with the battery wires facing the rear of the model. 3.
THE TRAXXAS TQ RADIO SYSTEM TQ RADIO SYSTEM CONTROLS RN LEF T TU Brake/Reverse RN RIGH TU Don’t push the transmitter antenna down from the top. Pull it down from the bottom, one segment at a time, to prevent binding and kinking the antenna mast. T Neutral Electronic Throttle Trim The electronic throttle trim located on the face of the transmitter adjusts the neutral (center) point of the electronic speed control. This control has been preset for you at the factory.
THE TRAXXAS TQ RADIO SYSTEM TQ RADIO SYSTEM RULES Channel 1 Brown Each time you prepare to run your model, you must clear your frequency to be sure no one else in the area is using the same channel as you. There are six possible channels, numbered 1 through 6. Each is represented by a color. Look at the crystal plugged into the back of your transmitter to determine which channel your model is assigned to.
ADJUSTING THE ELECTRONIC SPEED CONTROL The electronic speed control is factory set and should not require any adjustments. These instructions are provided for your reference. XL-2.5 ESC Specifications Input Voltage: 4-8 Cells (4.8V - 9.6V DC) Case Size (W x D x H): 26.5 x 46.5 x 22mm Weight: 33 Grams Motor Limit (380 Size): 10-turns* On-Resistance (@Trans): 0.008 Ohms Reverse Delay: None BEC Voltage: 6.
ADJUSTING THE ELECTRONIC SPEED CONTROL ESC Profile Selection The speed control is factory set to Profile #1. To change the profile, follow the steps on described below. The speed control should be connected to the receiver and battery, and the transmitter should be adjusted as described previously. The profiles are selected by entering the programming mode.
DRIVING YOUR MODEL Now it’s time to have some fun! This section contains instructions on driving and making adjustments to your model. Before you go on, here are some important precautions to keep in mind. Allow the model to cool for a few minutes between runs. This is particularly important when using high capacity battery packs that allow extended periods of running. Monitoring temperatures will extend the lives of the battery and motor.
DRIVING YOUR MODEL Not all batteries can be used in wet environments. Consult your battery manufacturer to see if their batteries can be used in wet conditions. The Traxxas TQ transmitter is not water resistant. Do not subject it to wet conditions such as rain. Do NOT operate your model during a rain storm or other inclement weather where lightning may be present.
DRIVING YOUR MODEL • Transmission: Remove, disassemble, and clean the transmission components. No grease is required for the nylon gears. Refer to your exploded view diagrams for help with disassembly and reassembly. • Motor: Remove the motor, clean with aerosol motor cleaner, and reoil the bushings with lightweight motor oil. Be sure to wear eye protection when using spray aerosol cleaners.
TUNING ADJUSTMENTS Your model is factory-tuned for optimum performance on pavement and concrete surfaces. To tailor the performance and handling of your model to suit your driving style and available traction, your model has a number of adjustable features. Gearing, shock preload and damping, ride height, wheel toe and wheel camber can all be easily adjusted. SUSPENSION TUNING Total Travel Ride Height Adjustment Your model has threaded shock bodies that make it easy to adjust ride height.
TUNING ADJUSTMENTS A camber gauge (available at your local hobby shop) can be a useful tool for alignment setting. To achieve a good starting point for the slipper clutch, tighten the slipper clutch adjusting nut clockwise until the slipper clutch adjusting spring fully collapses (do not over tighten), and then turn the slipper clutch nut counterclockwise ¾ to 1 turn. Static Camber Adjustment The wheels can be set to have either positive or negative camber (see illustration below).
TUNING ADJUSTMENTS TRANSMISSION TUNING Adjusting the Slipper Clutch Your model is equipped with an adjustable Torque Control slipper clutch which is built into the large spur gear. The purpose of the slipper clutch is to prevent over-stressing of the drivetrain and transmission gears. It may also be used to regulate the amount of power sent to the rear wheels to prevent tire spin. When it slips, the slipper clutch makes a high-pitch, whining noise.
TUNING ADJUSTMENTS Gearing Compatibility Chart The chart on the left shows a full range of gear combinations. The stock ratio for is shown in green. The gear combinations in red are not suitable when using the included 6-cell battery, speed control and motor. These gear combinations have been included in this chart as they may be used with certain other aftermarket equipment combinations.
MAINTAINING YOUR MODEL Your model requires timely maintenance in order to stay in top running condition. The following procedures should be taken very seriously. Inspect the vehicle for obvious damage or wear. Look for: 1. Cracked, bent, or damaged parts 2. Check the wheels and steering for binding. 3. Check the operation of the shock absorbers. 4. Check the wiring for any frayed wires or loose connections. 5. Check the mounting of the receiver and servo(s) and speed control. 6.
