TRAXXAS TQ 2.4GHz RADIO SYSTEM INTRODUCTION Applying the Decals The main decals for your model have been applied at the factory. Additional decals have been printed on selfadhesive 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. Your model includes the TQ 2.4GHz transmitter. When powered on, the TQ 2.
TRAXXAS TQ 2.4GHz RADIO SYSTEM 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. 2-channel radio system - The TQ 2.4GHz 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. 2.
TRAXXAS TQ 2.4GHz RADIO SYSTEM XL-5 Wiring Diagram Your model is equipped with the Traxxas TQ 2.4GHz transmitter. The transmitter has two channels: Channel one operates the steering, and channel two operates the throttle. The receiver inside the model has three output channels. Your model is equipped with one servo and an electronic speed control.
TRAXXAS TQ 2.4GHz RADIO SYSTEM INSTALLING TRANSMITTER BATTERIES SELECTING BATTERIES FOR YOUR MODEL Your TQ 2.4GHz 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. One NiMH or 2s LiPo battery equipped with a Traxxas High-Current Connector is required. Traxxas Power Cell iD batteries are strongly recommended for maximum performance.
TRAXXAS TQ 2.4GHz RADIO SYSTEM 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. Visit Traxxas.com to learn more about this feature and available Traxxas iD chargers and batteries.
TRAXXAS TQ 2.4GHz RADIO SYSTEM RADIO SYSTEM CONTROLS • 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. TUR N GH RI T Remember, always turn the TQi transmitter on first and off last to avoid damage to your model.
TRAXXAS TQ 2.4GHz RADIO SYSTEM Using Reverse: While driving, push the throttle trigger forward to apply brakes. Once stopped, return the throttle trigger to neutral. Push the throttle trigger forward again to engage proportional reverse. Throttle reversing procedure: Note: Throttle reversing is often times unnecessary on electric models, as issues with the throttle can usually be solved by reprogramming the speed control and/or verifying that the motor is wired correctly.
TRAXXAS TQ 2.4GHz RADIO SYSTEM Higher Speeds Require Greater Distance The faster you drive your model, the more quickly it will near the limit of radio range. At top speeds, models can cover anywhere between 50 to 100 feet every second! It’s a thrill, but use caution to keep your model in range. If you want to see your model achieve its maximum speed, it is best to position yourself in the middle of the truck’s running area, not the far end, so you drive the truck towards and past your position.

ADJUSTING THE ELECTRONIC SPEED CONTROL XL-5 Operation To operate the speed control and test the programming, reconnect the motor wires and place the vehicle on a stable block or stand so that all of the driven wheels are off the ground. Note that in steps 1-8 below, Low-Voltage Detection is DISABLED (factory default) and the LED shines red. If Low-Voltage Detection is ACTIVATED, the LED will shine green instead of red in steps 1-8 below. Never use LiPo batteries while Low-Voltage Detection is disabled. 1.
ADJUSTING THE ELECTRONIC SPEED CONTROL Throttle Neutral Protection The XL-5 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 will operate properly. Selecting Training Mode (Profile #3: 50% Forward, 100% Brakes, 50% Reverse) 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 (2400mAh and above) battery packs that allow extended periods of running. Monitoring temperatures will extend the lives of the batteries and motor.
DRIVING YOUR MODEL RUNNING IN WET CONDITIONS Your new Traxxas model is designed with water-resistant features to protect the electronics in the model (receiver, servos, electronic speed control). This gives you the freedom to have fun driving your model through puddles, wet grass, snow, and through other wet conditions. Though highly water resistant, the model should not be treated as though it is submersible or totally, 100% waterproof. Water resistance applies only to the installed electronic components.
DRIVING YOUR MODEL 7. Let the model stand or you may blow off with compressed air. Placing the model in a warm, sunny spot will aid drying. Trapped water and oil will continue to drip from the car for a few hours. Place it on a towel or piece of cardboard to protect the surface underneath. 8. As a precautionary step, remove the sealed receiver box cover. While unlikely, humidity or tiny amounts of moisture or condensation may enter the receiver box during wet running.

ADJUSTING YOUR MODEL Motors and Gearing There are two different types of aftermarket motors that can be purchased for your model, stock and modified. Stock motors all have the same wire thickness and number of turns around the armature as governed by sanctioned racing organizations. They are inexpensive and widely available. Modified motors are more expensive, may feature ball bearings, and come in a variety of wire thicknesses and the number of turns of wire on the armature.
ADJUSTING YOUR MODEL Front differential Front Differential Removal 1. Turn the chassis over and remove the 3x12mm countersunk screw and the two 3x15mm countersunk screws that hold the front bumper/body mount to the bulkhead. 2. Remove the 3x12mm buttonhead screw that secures the front body mount to the differential cover. 3. Slide the front bumper/body mount assembly off of the chassis. 4. Remove the five 3x12mm button-head screws from the front chassis brace; remove the chassis brace. 5.
ADJUSTING YOUR MODEL CHASSIS ADJUSTABILITY Adjustable Body Mounts The 4-Tec 2.0 chassis features adjustable body mounts to accommodate many popular 200mm touring car body styles. To adjust the mounts forward or backward, simply remove the fixed screws and install them in the sliding channels. If you need to adjust for width, remove all four screws and pull the body posts out sideways. Reinsert the body posts in the opposite direction so that the screw will pass through the channel.
ADJUSTING YOUR MODEL Dual Rear Camber Link Mounts There are two separate Mounting Holes mounting points for the UPPER rear camber links. Changing MOUNTING the location does not affect performance, but will allow Mounting Holes the use of different bodies. The lower mounting points LOWER should be used with low-profile MOUNTING bodies; the upper mounting points will work with most body styles. Both mounting points feature two holes for wheel camber adjustment.
MAINTAINING YOUR MODEL Your model requires timely maintenance in order to stay in top running condition. The following procedures should be taken very seriously. Frequently 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, servo, and speed control. 6.
