TRAXXAS TQi RADIO SYSTEM INTRODUCTION Your model includes the latest Traxxas TQi 2.4GHz transmitter with Traxxas Link™ Model Memory. The transmitter’s easy-to-use design provides instant driving fun for new RC enthusiasts, and also offers a full compliment of pro-level tuning features for advanced users – or anyone interested in experimenting with the performance of their model. The steering and throttle channels feature adjustable Exponential, End Points, and Sub-Trims.
TRAXXAS TQi RADIO SYSTEM To prevent loss of radio range do not kink or cut the black wire, do not bend or cut the metal tip, and do not bend or cut the white wire at the end of the metal tip. NiCad - Abbreviation for nickel-cadmium. The original rechargeable hobby pack, NiCad batteries have very high current handling, high capacity, and can last up to 1000 charging cycles. Good charging procedures are required to reduce the possibility of developing a “memory” effect and shortened run times.
TRAXXAS TQi RADIO SYSTEM Your model is equipped with the TQi 2.4GHz transmitter with Traxxas Link™ Model Memory. The transmitter has two channels for controlling your throttle and steering. The receiver inside the model has 5 output channels. Your model is equipped with one servo and an electronic speed control.
TRAXXAS TQi RADIO SYSTEM If the status LED doesn’t light green, check the polarity of the batteries. If you see any other flashing signal from the LED, refer to the chart on page 29 to identify the code. INSTALLING TRANSMITTER BATTERIES SELECTING BATTERIES FOR YOUR MODEL Your TQi transmitter uses 4 AA batteries. The battery compartment is located in the base of the transmitter. Your model does not include a battery or charger.
TRAXXAS TQi RADIO SYSTEM INSTALLING THE BATTERY PACK RADIO SYSTEM CONTROLS 1. Push the battery hold-down toward the center of the truck using the two release tabs and lift the hold-down up and toward you. 2. Insert a fully charged battery into the battery compartment with the High Current Connector positioned toward the rear of the model. 3. Lower the battery hold-down and pull it toward the outside of the truck to snap it closed.
TRAXXAS TQi RADIO SYSTEM Remember, always turn the TQi transmitter on first and off last to avoid damage to your model. Stop immediately at the first sign of weak batteries. Never turn the transmitter off when the battery pack is plugged in. The model could run out of control. • Always use new batteries for the radio system. Weak batteries will limit the radio signal between the receiver and the transmitter. Loss of the radio signal can cause you to lose control of your model.
TRAXXAS TQi RADIO SYSTEM Range-Testing the Radio System Before each running session with your model, you should range-test your radio system to ensure that it operates properly. 1. Turn on the radio system and check its operation as described in the previous section. 2. Have a friend hold the model. Make sure hands and clothing are clear of the wheels and other moving parts on the model. 3. Walk away from the model with the transmitter until you reach the farthest distance you plan to operate the model. 4.
TRAXXAS TQi RADIO SYSTEM To prevent loss of radio range do not kink or cut the black wire, do not bend or cut the metal tip, and do not bend or cut the white wire at the end of the metal tip. Correct No 16 • MAXX No No SETTING UP THE ANTENNA The receiver antenna has been set up and installed from the factory. The antenna is secured by a 3x4mm set screw. To remove the antenna tube, simply remove the set screw with a 1.5mm wrench.
ADJUSTING THE ELECTRONIC SPEED CONTROL Electronic Speed Control Adjustments The VXL-4s electronic speed control’s default settings were programmed at the factory and should not require adjustment for normal operation. The following information is helpful to confirm the settings or allow you to customize the settings for your needs. ATTENTION: USING LiPo BATTERIES The VXL-4s electronic speed control is designed to operate on 3s or 4s LiPo battery power.
ADJUSTING THE ELECTRONIC SPEED CONTROL Selecting Sport Mode (Profile #1: 100% Forward, 100% Brakes, 100% Reverse) 1. Connect a fully charged battery pack to A the VXL-4s and turn on your transmitter. 2. Press and hold the EZ-Set button until the LED turns solid green, then solid red and Green to Red to Off then begins blinking red (indicating the C Profile numbers). 3. When the LED blinks red once, release the EZ-Set button. Release 4. The LED will blink and then turn solid green.
ADJUSTING THE ELECTRONIC SPEED CONTROL • Solid Green: VXL-4s power-on light. Low-Voltage Detection is ACTIVATED (LiPo setting). • Current LED (A) Solid Red: The VXL-4s has entered Overcurrent Protection, Stage 1. When excessive current flow (amperage) is being routed through the power system caused by failure to use the appropriate gearing ratio for the drivetrain and the driving surface, the VXL-4s will limit the power output to 50% throttle.
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 batteries and motors.
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 TQi 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 9. Additional Maintenance: Increase your frequency of disassembly, inspection, and lubrication of the following items. This is necessary after extended wet use or if the vehicle will not be used for an extended period of time (such as a week or longer). This additional maintenance is needed to prevent any trapped moisture from corroding internal steel components. • Stub axle housing and center driveline bearings: Remove, clean, and re-oil the bearings.
BASIC TUNING ADJUSTMENTS Once you become familiar with driving your model, you might need to make adjustments for better driving performance. SUSPENSION TUNING Shock Mounting Positions Big bumps and rough terrain require a softer suspension with the maximum possible suspension travel and ride height. Racing on a prepared track or on-road use requires a lower ride height and firmer, more aggressive suspension settings.
