This procedure will help to prevent your model from receiving stray signals from another transmitter, or other source, and running out of control.
TRAXXAS TQi RADIO SYSTEM USING THE RADIO SYSTEM Automatic Fail-Safe The TQi transmitter and receiver are equipped with an automatic fail-safe system that does not require user programming. In the event of signal loss or interference, the throttle will return to neutral and the steering will hold its last commanded position. If the fail-safe activates while you are operating your model, determine the reason for signal loss and resolve the problem before operating your model again.
TRAXXAS TQi RADIO SYSTEM TQi Binding Instructions For proper operation, the transmitter and receiver must be electronically “bound.” This has been done for you at the factory. Should you ever need to re-bind the system or bind to another transmitter or receiver, follow these instructions. Note: The receiver must be connected to a 4.8-6.0v (nominal) power source for binding. Vehicles equipped with an electronic speed control contain a BEC that provides a lower voltage to power the receiver (see page 11).

ADJUSTING THE ELECTRONIC SPEED CONTROL Throttle Neutral Protection The XL-5 HV speed control features Throttle Neutral Protection, which prevents the model from suddenly accelerating if the speed control is switched on while the transmitter’s trigger is being held. When the trigger is returned to neutral, the XL-5 HV will operate properly. Selecting Trail Mode (Profile #4: 100% Forward, 100% Brakes, 100% Reverse; A B Drag Brake at Neutral) 1.
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 motor.
DRIVING YOUR MODEL About Run Time A large factor affecting run time is the type and condition of your batteries. The milliamp hour (mAh) rating of the batteries determines how large their “fuel tank” is. A 3000 mAh battery pack will theoretically run twice as long as a 1500 mAh sport pack. Because of the wide variation in the types of batteries that are available and the methods with which they can be charged, it’s impossible to give exact run times for the model.
DRIVING YOUR MODEL Motor Precautions • Titan 550 motor life can be greatly reduced in mud and water. If the motor gets excessively wet or submerged, use very light throttle (run the motor slowly) until the excess water can run out. Applying full throttle to a motor full of water can cause rapid motor failure. Your driving habits will determine motor life with a wet motor. Do not submerge the motor under water. • Do not gear the motor by temperature when running in wet conditions.
DRIVING YOUR MODEL RECEIVER BOX: MAINTAINING A WATERTIGHT SEAL Removing and Installing Radio Gear The unique design of the receiver box allows the removal and installation of the receiver without losing the ability to maintain a watertight seal in the box. The patent-pending wire clamp feature gives you the ability to also install aftermarket radio systems and maintain the watertight features of the receiver box. Removing the Receiver 1. To remove the cover, remove the three 3x8mm button-head cap screws.
TUNING ADJUSTMENTS Adjustment procedures for alignment, spring rate, damping, steering, and ride height are covered here. SUSPENSION TUNING Replacing Shock Oil The shocks have to be removed from the vehicle and disassembled to change the oil. Springs TRX-4’s front spring (0.45 rate, no stripe) and rear spring (0.54 rate, green stripe) have been carefully selected to provide full suspension articulation and support for the weight of the vehicle body.
TUNING ADJUSTMENTS Never slide the threads on the shock rod past the X-ring seals when it is installed and compressed by the bottom cap of the shock. Doing so will damage the seal and cause shock oil to leak. Shock assembly 1. Insert the shock shaft assembly through the shock body until the piston bottoms out. 2. Lubricate the shaft, O-ring, and X-rings with silicone oil. 3. Install the O-ring, X-rings and spacer over the shaft and into the bore of the shock body. 4. Install the lower cap. 5.
TUNING ADJUSTMENTS The TRX-4 is equipped from the factory with a 45-tooth spur gear and 11-tooth pinion gear. TRX-4 has a large range of gearing, making it suitable for many different types of applications and environments. If you want more acceleration and less top speed, use a smaller pinion gear (fewer teeth, higher numerical ratio). The overall reduction is the number of turns the motor makes for one revolution of the tire.
TUNING ADJUSTMENTS Adjusting Gear Mesh Incorrect gear mesh is the most common cause of stripped spur gears. Your model includes a fixed gear positioning system to simplify the process and ensure proper gear mesh settings. Access the gears by removing the three 3x8mm buttonhead screws from the gear cover; remove the gear cover. Remove the motor/motor plate assembly from the chassis.
TUNING ADJUSTMENTS T-LOCK SERVO INSTALLATION FITTING AFTERMARKET BODIES The TRX-4’s T-Lock differential control servos are installed and pre-set at the factory. If you need to remove the servos or the servo horns for maintenance or cleaning, carefully note their orientation when you reinstall them to make certain the T-Lock system operates properly. Rear Shock Tower The rear shock tower can be installed in two different locations and in two orientations each.
MAINTAINING YOUR MODEL Always wear eye protection when using compressed air or spray cleaners and lubricants. 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.
TQi ADVANCED TUNING GUIDE Your Traxxas transmitter has a programmable Multi-Function knob that can be set to control various advanced transmitter functions (set to Cruise Control by default, see page 17). Accessing the programming menu is done by using the menu and set buttons on the transmitter and observing signals from the LED. An explanation of the menu structure follows on page 34. Experiment with the settings and features to see if they can improve your driving experience.
TQi ADVANCED TUNING GUIDE Failsafe Your Traxxas radio system is equipped with a built-in failsafe function that returns the throttle to its last saved neutral position in the event of a signal loss. The LED on the transmitter and on the receiver will rapidly flash red. In order to re-acquire the signal after the failsafe has activated, you will need to walk a longer distance closer to the model than the distance the model travelled out of range.
TQi ADVANCED TUNING GUIDE Setting Lock Once you’ve adjusted all of these settings the way you like them, you may want to disable the Multi-Function knob so none of your settings can be changed. This is especially handy if you operate multiple vehicles with a single transmitter via Traxxas Link™ Model Memory. Multiple Settings and the Multi-Function Knob It is important to note that settings made with the Multi-Function knob are “overlaid” on top of each other.
