How do I apply the decals?
The main decals for your model have been applied at the factory. Additional decals are printed on self-adhesive clear mylar and are die-cut for easy removal. Use a hobby knife to lift the corner of a decal and lift it from the backing. To apply the decals, place one end down, hold the other end up, and gradually smooth the decal down with your finger as you go. This will prevent air bubbles. Placing both ends of the decal down and then trying to smooth it out will result in air pockets. Look at the photos on the box for typical decal placement.
What is BEC?
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.
What is current?
Current – Current is a measure of power flow through the electronics, usually measured in amps. If you think of a wire as a garden hose, current is a measure of how much water is flowing through the hose.
What is ESC?
ESC (Electronic Speed Control) – An electronic speed control is the electronic motor control inside the model. The EVX-2 uses MOSFET power transistors to provide precise, digital proportional throttle control. Electronic speed controls use power more efficiently than mechanical speed controls so that the batteries run longer. An electronic speed control also has circuitry that prevents loss of steering and throttle control as the batteries lose their charge.
What is frequency band?
Frequency band – The radio frequency used by the transmitter to send signals to your model. This model operates on the 2.4GHz direct-sequence spread spectrum.
What is LiPo?
LiPo – Abbreviation for Lithium Polymer. Rechargeable LiPo battery packs are known for their special chemistry, which allows extremely high energy density and current handling in a compact size. These are high performance batteries that require special care and handling. LiPo battery packs are for advanced users only.
What is mAh?
mAh – Abbreviation for milliamp hour, a measure of the capacity of the battery pack. The higher the number, the longer the battery will last between recharges.
What is neutral position?
Neutral position – The standing position that the servos seek when the transmitter controls are at the neutral setting.
What is NiCad?
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.
What is NiMH?
NiMH – Abbreviation for nickel-metal hydride. Rechargeable NiMH batteries offer high current handling and much greater resistance to the “memory” effect. NiMH batteries generally allow higher capacity than NiCad batteries. They can last up to 500 charge cycles. A peak charger designed for NiMH batteries is required for optimal performance.
What is a receiver?
Receiver – The radio unit inside your model that receives signals from the transmitter and relays them to the servos.
What is resistance?
Resistance – In an electrical sense, resistance is a measure of how an object resists or obstructs the flow of current through it. When flow is constricted, energy is converted to heat and is lost.
What is a servo?
Servo – Small motor unit in your model that operates the steering mechanism.
What is a transmitter?
Transmitter – The hand-held radio unit that sends throttle and steering instructions to your model.
What is trim?
Trim – The fine-tuning adjustment of the neutral position of the servos, made by adjusting the throttle and steering trim knobs on the face of the transmitter. Note: The Multi-Function knob must be programmed to serve as a throttle trim adjustment.
What is Thermal Shutdown Protection?
Thermal Shutdown Protection – Temperature sensing electronics are used in the ESC to detect overloading and overheating of the transistor circuitry. If excessive temperature is detected, the unit automatically shuts down to prevent damage to the electronics.
What is a 2-channel radio system?
2-channel radio system – The TQ radio system, consisting of the receiver, the transmitter, and the servos. The system uses two channels: one to operate the throttle and one to operate the steering.
What is 2.4GHz Spread Spectrum?
4GHz Spread Spectrum – This model is equipped with the latest R/C technology. Unlike AM and FM systems that require frequency crystals and are prone to frequency conflicts, the TQi system automatically selects and locks onto an open frequency and offers superior resistance to interference and “glitching.”
What is voltage?
Voltage – Voltage is a measure of the electrical potential difference between two points, such as between the positive battery terminal and ground. Using the analogy of the garden hose, while current is the quantity of water flow in the hose, voltage corresponds to the pressure that is forcing the water through the hose.
What do the numbers 550 and 540 refer to?
550 and 540 – These numbers refer to the size of the motor.
How do I install the transmitter batteries?
Your TQi transmitter uses 4 AA batteries. The battery compartment is located in the base of the transmitter.
- Remove the battery compartment door by pressing the tab and sliding the door open.
- Install the batteries in the correct orientation as indicated in the battery compartment.
- Reinstall the battery door and snap it closed.
- Turn on the transmitter and check the status indicator for a solid green light.
If the status LED flashes red, the transmitter batteries may be weak, discharged or possibly installed incorrectly. Replace with new batteries. The power indicator light does not indicate the charge level of the battery pack installed in the model. Refer to the Troubleshooting section on page 32 for more information on the transmitter Status LED codes. If the status LED doesn’t light green, check the polarity of the batteries. Check rechargeable batteries for a full charge. If you see any other flashing signal from the LED, refer to the chart on page 32 to identify the code.
What type of batteries should I use?
Your transmitter uses AA batteries. Use new alkaline batteries. Do not use rechargeable AA cells to power the TQi transmitter, as they will not provide sufficient voltage for optimum transmitter performance. Caution: Discontinue running your model at the first sign of weak batteries (flashing red light) to avoid losing control.
How do I select batteries for my model?
Your model does not include a battery or charger. The speed control in the model is compatible with both LiPo and NiMH batteries. One NiMH or 2s/3s LiPo battery equipped with a Traxxas High-Current Connector is required. Traxxas Power Cell iD batteries are strongly recommended for maximum performance and safer charging.
How do I select a charger for my model?
Make certain you choose the correct type of charger for the batteries you select. Traxxas recommends you choose a genuine Traxxas EZ-Peak iD charger for safer charging and maximum battery life and performance.
How do I install the battery pack?
WARNING: Do not pinch the battery wires or connector between the body wheel wells and the chassis when installing the battery. Install the battery pack with the battery wires facing the rear of the model. Swing the battery hold down towards the chassis and snap (lock) the end into the front hold-down retainer. Note: The battery hold down can be rotated on its pivot to accommodate different height battery packs.
What is Battery iD?
Traxxas recommended battery packs are equipped with Traxxas Battery iD. This exclusive feature allows Traxxas battery chargers (sold separately) to automatically recognize connected battery packs and optimize the charge settings for the battery. This eliminates the need to worry over charger settings and menus for the easiest and safest charging solution possible.
What radio system rules should I follow?
- Always turn your TQi transmitter on first and off last. This procedure will help to prevent your model from receiving stray signals from another transmitter, or other source, and running out of control. Your model has electronic fail-safes to prevent this type of malfunction, but the first, best defense against a runaway model is to always turn the transmitter on first and off last.
- 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.
- In order for the transmitter and receiver to bind to one another, the receiver in the model must be turned on within 20 seconds of turning on the transmitter. The transmitter LED will flash fast red, indicating a failure to link. If you miss it, simply turn off the transmitter and start over.
- Always turn on the transmitter before plugging in the battery.
How do I make basic adjustments to the radio system?
Throttle Neutral Adjustment
The throttle neutral adjustment is located on the transmitter face and controls the forward/reverse travel of the throttle trigger. Change the adjustment by pressing the button and sliding it to the desired position. There are two settings available:
- 50/50: Allows equal travel for both acceleration and reverse.
- 70/30: Allows more throttle travel (70%) and less reverse travel (30%).
Steering Trim
Turn the steering trim knob to precisely set the steering neutral point. To adjust, drive the vehicle forward slowly while “steering” with the trim knob until the vehicle travels in a straight line with no steering input.
Multi-Function Knob
The Multi-Function knob can be programmed to control a variety of functions. From the factory, the Multi-Function knob controls Cruise Control on the TRX-4.
What should I remember regarding radio system controls?
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.
What is 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.
How do I use the radio system?
The TQi Radio System has been pre-adjusted at the factory. The adjustment should be checked before running the model in case of movement during shipping. Here’s how:
- Turn the transmitter switch on. The status LED on the transmitter should be solid green (not flashing).
- Elevate the model on a block or a stand so that all the tires are off the ground. Make sure your hands are clear of the moving parts of the model.
- Plug the battery pack in the model into the speed control.
- Press and release the EZ-Set button on the speed control to turn the model on. The speed control’s LED will glow green, indicating that Low-Voltage Detection is activated to prevent over-discharging of LiPo batteries (this may cause poor performance from NiMH battery packs). Never use LiPo batteries while Low-Voltage Detection is disabled. See page 18 for more information. To turn the speed control off, press the EZ-Set button until the LED turns off.
- Turn the steering wheel on the transmitter back and forth and check for rapid operation of the steering servo. Also, check that the steering mechanism is not loose or binding. If the steering operates slowly, check for weak batteries.
- When looking down at the model, the front wheels should be pointing straight ahead. If the wheels are turned slightly to the left or right, slowly adjust the steering trim control on the transmitter until they are pointing straight ahead.
- Gently operate the throttle trigger to ensure that you have forward and reverse operation, and that the motor stops when the throttle trigger is at neutral. WARNING: Do not apply full throttle in forward or reverse while the model is elevated.
- Once adjustments are made, turn off the receiver on your model, followed by the hand-held transmitter.
How do I range-test the radio system?
Before each running session with your model, you should range-test your radio system to ensure that it operates properly.
- Turn on the radio system and check its operation as described in the previous section.
- Have a friend hold the model. Make sure hands and clothing are clear of the wheels and other moving parts on the model.
- Walk away from the model with the transmitter until you reach the farthest distance you plan to operate the model.
- Operate the controls on the transmitter once again to be sure that the model responds correctly.
- Do not attempt to operate the model if there is any problem with the radio system or any external interference with your radio signal at your location.
How do I prevent loss of radio range?
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.
How do I bind the TQi?
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. The transmitter and receiver must be within 5 feet of each other.
- Press and hold the transmitter’s SET button as you switch the transmitter on. The transmitter’s LED will flash red slowly. Release the SET button.
- Press and hold the receiver’s LINK button as you switch on the speed control (by pressing the EZ-Set button). Release the LINK button.
- When the transmitter and receiver’s LEDs turn solid green, the system is bound and ready for use. Confirm that the steering and throttle operate properly before driving your model.
How does Cruise Control operate?
The Multi-Function Knob on the TQi transmitter has been programmed to control Cruise Control on the TRX-4, which maintains vehicle speed for more comfortable long-distance travel (such as hiking on trails). To operate Cruise Control, accelerate to your desired speed and press the SET button on the transmitter to lock the speed in. Your model will continue at the set speed until you apply the brakes. You can fine tune the speed to exactly match your pace by adjusting the multi-function knob on the transmitter. Turn the knob clockwise to increase speed, counterclockwise to reduce speed. You can accelerate and drive faster with the Cruise Control set, and the vehicle will resume the set speed when the throttle is released (Resume function).
How do I set 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 the included 1.5mm wrench. When reinstalling the antenna, first slide the antenna wire into the bottom of the antenna tube until the white tip of the antenna is at the top of the tube under the black cap. Next, insert the antenna tube into the mount while making sure that the antenna wire is in the slot in the antenna mount; then, install the set screw next to the antenna tube. Use the supplied 1.5mm wrench to tighten the screw just until the antenna tube is securely in place. Do not over tighten. Do not bend or kink the antenna wire! Do not shorten the antenna tube.

How do the XL-5 HV Battery Settings (Low-Voltage Detection Setting) work?
The XL-5 HV electronic speed control is equipped with built-in Low-Voltage Detection. The Low-Voltage Detection circuitry constantly monitors the battery voltage. When the battery voltage begins to reach the minimum recommended discharge voltage threshold for LiPo battery packs, the XL-5 HV will limit the power output to 50% throttle. When the battery voltage attempts to fall below the minimum threshold, the XL-5 HV will shut down all motor output. The LED on the speed control will slowly blink red, indicating a low-voltage shutdown. The XL-5 HV will stay in this mode until a fully charged battery is connected. When you turn your model on, the XL-5 HV speed control’s status LED will glow green, indicating that Low-Voltage Detection is activated to prevent over-discharging of LiPo batteries. LiPo batteries are intended only for the most advanced users that are educated on the risks associated with LiPo battery use.
Verify that Low-Voltage Detection is ACTIVATED:
- Turn on the transmitter (with the throttle at neutral).
- Connect a fully charged battery pack to the XL-5 HV.
- Press and release the EZ-Set button to turn the XL-5 HV on. If the LED is solid green, then the Low-Voltage Detection is ACTIVATED.
If Low-Voltage Detection is DISABLED:
- Make sure the LED on the XL-5 HV is on and RED.
- Press and hold the EZ-Set button (the LED will turn off). After ten seconds, the motor will beep twice and the LED will shine GREEN. Release the button.
- Low-Voltage Detection is now ACTIVATED.
For NiMH battery users, follow these steps to disable Low-Voltage Detection (NiMH setting):
- Make sure the LED on the XL-5 HV is on and GREEN.
- Press and hold the EZ-Set button (the LED will turn off). After ten seconds, the motor will beep three times and the LED will shine RED. Release the button.
- Low-Voltage Detection is now DISABLED.
How do I setup the XL-5 HV?
Read through all of the programming steps before you begin. If you get lost during programming or receive unexpected results, simply unplug the battery, wait a few seconds, plug the battery pack in, and start over.
- Disconnect one of the motor wires between the XL-5 HV and the motor. This is a precaution to prevent runaway when the speed control is turned on before it is programmed.
- Connect a fully charged battery pack to the XL-5 HV.
- Turn on the transmitter (with the throttle at neutral).
- Press and hold the EZ-Set button (A). The LED will first turn green and then red. Release the button.
- When the LED blinks RED ONCE, pull the throttle trigger to the full throttle position and hold it there (B).
- When the LED blinks RED TWICE, push the throttle trigger to the full reverse and hold it there ©.
Note: If you are calibrating to clear an error code on the ESC, then skip step 7 and proceed to step 8.
- When the LED blinks GREEN ONCE, programming is complete. The LED will then shine green or red (depending on Low-Voltage Detection setting).
- When the LED blinks GREEN ONCE, continue holding the trigger in the reverse position and also press and hold the button on the ESC for about 10 seconds until the ESC beeps. This places the ESC in NiMH mode and clears any error codes.

ASSEMBLY HINTS To assemble this kit, youll need a large flat working area where you will have plenty of room to build. Be sure its a place where you can leave your work spread out and not in the way when you want to take a break from the assembly. Allow yourself plenty of time to build this kit; assembly time is going to vary with each individual. Experienced
builders may only need 4-5 hours to assemble this kit, while others may spend an entire weekend on it. You should feel comfortable with taking as much time as needed to properly build and set up your model.
If youve been exploring the contents of your kit box, youve noticed many bags of small parts. Open only one bag at a time. To keep the parts organized, use small paper plates or several large plastic plates with partitions to contain the parts. Label the paper plates, and then pour the contents of the bags onto them. This puts the parts out in the open where you can find them easily. The plates also prevent small parts from rolling off the table.
Please read the text next to each diagram. The text contains important information, such as assembly steps, screw sizes, and part numbers. Also, pay attention to any notes that may follow some steps. Before you attempt to run your newly-built model, please read all of the instructions and precautions included in the Owners Manual. You can download the Owners Manual for the TRX-4, as well as the manuals for all Traxxas vehicles, at Traxxas.com.
