Failure to operate your model in a safe and responsible manner may result in property damage and serious injury. The precautions outlined in this manual should be strictly followed to help ensure safe operation. You alone must see that the instructions are followed and the precautions are adhered to. Important Points to Remember Your model is not intended for use on public roads or congested areas where its operation can conflict with or disrupt pedestrian or vehicular traffic. Never, under any circumstances, operate the model in crowds of people. Your model is very fast and could cause injury if allowed to collide with anyone. Because your model is controlled by radio, it is subject to radio interference from many sources that are beyond your control. Since radio interference can cause momentary losses of radio control, always allow a safety margin in all directions around the model in order to prevent collisions. The motors, batteries, and speed control can become hot during use. Be careful to avoid getting burned. Don’t operate your model at night, or anytime your line of sight to the model may be obstructed or impaired in any way. Most importantly, use good common sense at all times. Batteries and Battery Charging Your model uses rechargeable batteries that must be handled with care for safety and long battery life. Make sure to read and follow all instructions and precautions that were provided with your battery packs and your charger. It is your responsibility to charge and care for your battery backs properly. In addition to your battery and charger instructions, here are some more tips to keep in mind. Never leave batteries to charge unattended. Remove the batteries from the model while charging. Always unplug the batteries from the electronic speed control when the model is not in use and when it is being stored or transported. Allow the battery packs to cool off between runs (before charging). Do not use battery packs that have been damaged in any way. Do not use battery packs that have d wiring, or a damaged connector.

Decorating your Model Applying The Decals The main decals for your model have been applied at the factory. The 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. Tire Gluing The factory tires on your E-Maxx are alre tires must be glued to the rims to preven inside the tires.

The Traxxas TQ Radio System Use the Right Batteries Your transmitter uses AA batteries. Use new alkaline batteries, or rechargeable batteries such as NiCad or NiMH (Nickel Metal Hydride) batteries in your transmitter. Make sure rechargeable batteries are fully charged according to the manufacturer’s instructions. If you use rechargeable batteries in your transmitter, be aware that when they begin to lose their charge, they lose power more quickly than regular alkaline batteries. Caution: Discontinue running your model at the first sign of weak batteries (flashing red light) to avoid losing control. Radio System Terminology Please take a moment to familiarize yourself with these radio- 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. Channel - The 27 MHz frequency band is divided into 6 channels so that up to six models can be operated simultaneously. Each channel is referred to by its flag color and channel number, as shown below. Clearing your frequency - A routine, verbal check to make sure nobody else in your area is operating on the same channel. Always clear your frequency by calling out your channel number before operating your model. Wait or move to another area if your channel is already being used. Crystal (X-tal) - The plug-in device that determines which channel the radio system will operate on. For each channel, there are two crystals, one for the receiver and one for the transmitter. Of those two crystals, the one marked with the lower number (.455 MHz lower) must be inserted into the receiver. 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. Frequency band - The radio frequency used by the transmitter to send signals to your model. All Traxxas RTR models operate on a 27 MHz frequency band. mAh – Abbreviation for milliamp hour. A the battery pack. The higher the numb will last between recharges. Neutral position - The standing position the transmitter controls are at the neu NiCad - Abbreviation for nickel-cadmium hobby pack, NiCad batteries have very high capacity, and can last up to 1000 charging procedures are required to r developing a “memory” effect and sho NiMH - Abbreviation for nickel-metal hy batteries offer high current handling, to the “memory” effect.

Installing Transmitter Batteries Your TQ transmitter uses 8 AA batteries (see sidebar, page 10). The battery compartment is located in the base of the transmitter. 1. Remove the battery compartment door by pressing the tab and lifting the door up. 2. Install the batteries in the correct orientation as indicated in the battery compartment. 3. Reinstall the battery door and snap it closed. 4. Turn on the transmitter and check the power indicator for a solid red light. If the power indicator light flashes, then the transmitter batteries are weak, discharged or possibly installed incorrectly. Replace with new or freshly charged batteries. The power indicator light does not indicate the charge level of the battery pack installed in the model. Setting up the Antenna 1. Locate the black antenna wire that exits the receiver box. 2. Pull the wire straight with your fingers and then insert the end of the wire into one end of the antenna tube (the antenna tube, tip, crimp nut and sleeve are located in the documents bag). Push the wire all the way through the antenna tube. 3. Insert the base of the tube into the antenna post. Take care not to crimp the antenna wire. 4. Slide the crimp nut over the antenna tube and screw it onto the antenna post. Use the supplied tool to tighten the crimp nut on the post just until the antenna tube is securely in place. Do not over tighten or crush the antenna wire against the chassis. 5. Fold the top of the antenna wire over the top of the antenna tube. Slide the antenna sleeve over the tube to retain the antenna wire. Now slide the antenna tip onto the top of the antenna tube. Never cut or shorten the antenna wire. 6. On the transmitter, always fully extend the telescoping antenna when running your model. Make a habit of holding the transmitter so the antenna points straight up.

The Traxxas TQ Radio System Installing Battery Packs The E-Maxx requires two fully charged 7.2 or 8.4-volt (stick style) NiMH battery packs. These batteries are not included with the model. For the best performance, use 7-cell battery packs. When using 6-cell battery packs, install the supplied foam block (spacer) into the front of the battery compartment. The spacers are located in your instructions package. The spacers are shaped to conform to the chassis. There is a right and a left. Test fit them to confirm their location. Remove the backing from the self adhesive strips and secure them to the front of the battery compartments. Using Different Battery Configurations The battery hold-downs are capable of accommodating either side-by-side racing style packs or the more common stick packs. The battery compartments are configured for stick packs from the factory. The number on each side of the hold down indicates the battery height in millimeters that hold-down can accommodate. Note that one side is labeled “25” and other side is labeled “23”. The 25mm side is for use with typical stick type battery packs. If you are using side-by-side racing packs, simply flip the hold- down over to the 23mm side and use it on the opposite side of the chassis. Accessory hold downs and foam (part #3927X) are available to accommodate larger battery packs. See the 3905 E-Maxx parts list for more information. Battery Installation 1. Remove the battery hold- down by pressing on the release tab and lifting out the hold-down. 2. Install the battery pack with the battery wires facing the rear of the model. Your model includes foam blocks which should be installed behind 6-cell batteries for a more secure fit. 3. Insert the tabs of the battery hold-down into the slots in the rear hold-down retainer (A). Swing the battery hold down towards the chassis and snap (lock) the end into the front h The Traxxas High Current Connector Your model is equipped with the Traxxa High-Current Connector. Standard conn restrict current flow and are not capable delivering the power needed to maximi output of the EVX-2. The Traxxas conne gold-plated terminals with a large conta current flow with the least amount of re lasting, and easy to grip, the Traxxas con extract all the power your battery has to To run this model, your batteries must b High-Current Connectors. Batteries can with Traxxas connectors installed or Tra purchased to install on battery packs yo on page 13 for packages available from The typical Molex style connector is inad use in your model. It creates resistance th a bottleneck to current flow. If your batt is equipped with a Molex connector, it replaced with a Traxxas High-Current C mate with the EVX-2 electronic speed c Use the Right Charger The most convenient type of charger is an AC peak- detecting charger that plugs directly into an AC wall outlet. It contains special peak-detection circuitry that automatically shuts the charger off when the battery is fully charged. If you’re using a 15-minute timed charger, always fully discharge the battery pack before each charge. Some high mAh battery packs (1500 mAh or higher) require more than the standard 15 minutes of charge time. If the battery pack is cold after 15 minutes of charging, add another 5 minutes of charge time. Closely monitor the battery pack and stop charging it when it begins to feel warm to the touch. Never leave a battery charging unattended. Always follow charger manufacturer’s instructions. Warning: Lithium Polymer (LiPo) batteries should not be used with the EVX-2. The EVX-2 is not equipped with low-voltage detection. 25mm side: Standard NiMH stick pack setup 23mm side: Side-by-side NiMH pack setup “25” - Standard stick packs “23” - Side-by-side packs Release Foam Block 6-cell B

In addition to the electronic throttle and steering trim controls, your radio system features throttle neutral adjustment and servo reversing switches. These are preset at the factory and should not require further adjustment. 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%). Note: If you change throttle travel, you will need to reprogram the electronic speed control. 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. Electronic Steering Trim The electronic steering trim located on the face of the transmitter adjusts the neutral (center) point of the steering servos when the servos are at rest. Adjust this control to make the model drive straight with no steering input at the wheel. Servo Reversing Switches The servo reversing switches are located on the front of the transmitter, next to the on/off switch. Moving a switch reverses the direction of the corresponding servo. Each switch corresponds to a channel, as shown below. For example, if you turn the steering wheel to the right and your wheels turn left, you would move the Channel 1 switch to correct the servo direction. It may be necessary to adjust the corresponding trim control after moving a switch.

Your speed control was adjusted to the radio from the factory. It is possible for the throttle trim control on the transmitter to have moved during transit or while handling the transmitter. If the motors run when the model is switched on, then move the throttle trim control on the transmitter until the motors stop. If anything more than a slight adjustment of the throttle trim control is required, then you should readjust your speed control. Refer to the adjustments section on page 15. Remember, always turn the TQ transmitter on first and off last to avoid damage to your model. When rechargeable batteries begin to lose their charge, they will fade much faster than alkaline dry cells. 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. TQ Radio System Rules 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. Always turn your TQ 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. Always have the transmitter turned on before plug in the battery. Always use new or freshly charged batteries for the radio system. Weak batteries will limit the range of the radio signal between the receiver and the transmitter. Loss of the radio signal can cause you to lose control of your model. TQ Radio System Setup The TQ Radio System was pre-adjusted at the factory. The adjustment should be checked, before running the model, in case of movement during shipping. Here’s how: 1. Fully extend the chrome antenna mast on the transmitter and turn the switch on. The red indicator light on the transmitter should be solid red (not flashing). 2. Elevate the model so that all four tires are off the ground. If you are holding the model, grip it firmly. Make sure your hands are clear of the moving parts of the model. 3. Plug the battery pack in the model into the speed control. 4. The on/off switch is integrated into t the transmitter on, press the EVX-2 set the LED shines GREEN, then immediat turns the model on (see page 15 for m operation).

any adjustments. These instructions are provided for your reference. Transmitter Adjustments for the EVX-2 ESC Before attempting to program your EVX-2, it is important to make sure your TQ transmitter is properly adjusted (set back to the factory defaults). Otherwise, you may not get the best performance from your speed control. The transmitter should be adjusted as follows: 1. Set the throttle neutral switch to the 50/50 setting. This adjusts the transmitter’s throttle trigger throw to 50% for throttle and 50% for braking and reverse. 2. Set the throttle trim control to the middle “0” setting. 3. Set the Channel 2 servo reversing switch to the left position. Do not change the position of any of the servo reversing switches after programming the EVX-2. 4. You are now ready to program your speed control. Setup Programming (Calibrating your ESC and transmitter) Read through all of the following 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 back in, and start over. 1. Disconnect each of the motor wires between the EVX-2 and the motors. This is a precaution to prevent runaway when the speed control is turned on before it is programmed. 2. Connect two fully charged battery packs to the EVX-2. 3. Turn on the transmitter (with the throttle at neutral). 4. Press and hold the EZ-Set button (A). The LED will first turn green and then red. Release the EZ-Set button. 5. When the LED blinks RED ONCE. Pull the throttle trigger to the full throttle position and hold it there (B). 6. When the LED blinks RED TWICE. Push the throttle trigger to the full reverse and hold it there (C). 7. When the LED turns solid GREEN, programming is complete. The LED will continuously shine green indicating the EVX-2 is on and at neutral (D). EVX-2 Operation To operate the speed control and test the programming, place the vehicle on a stable block or stand so all of the driven wheels are off the ground. Reconnect the motor wires. Always make sure that objects and fingers are clear of the wheels. 1. With the transmitter on, press the EZ-Set button for ½ second, until the LED shines GREEN, then immediately release the button. This turns on the EVX-2. If you press and release too quickly, you may hear the steering servos jump but the LED may not stay on. (Note: If the throttle is not at neutral or if the throttle trim has been altered, the LED will turn off after one second and the wheels may begin to drive.) 2. Apply forward throttle. The LED will turn off until full throttle power is reached. At full throttle, the led will shine GREEN. 3. Move the trigger forward to apply the brakes. Note that braking control is fully proportional. The LED will turn off until full braking power is reached. At full brakes, the LED will shine GREEN. 4. Return the throttle trigger to neutral. The LED will shine GREEN. 5. Move the throttle trigger forward again to engage reverse (Profile #1). The LED will turn off. Once full reverse power is reached, the LED will shine GREEN. 6. To stop, return the throttle trigger to neutral. Note that there is no programmed delay when changing from reverse to forward. Use caution to avoid slamming the speed control from reverse to forward. On high-traction surfaces, this could result in transmission or driveline damage. 7. To turn the EVX-2 off, press the EZ-Set button until the green LED turns off. Adjusting the Electronic Speed Control A Green then Red B Once Red C Twice Red D Solid Green

Patent Pending Training Mode (Profile #3) reduces forward and reverse throttle by 50%. Training Mode is provided to reduce the power output allowing beginning drivers to better control the model. As driving skills improve, simply change to Sport or Race Mode for full-power operation. Thermal Shutdown Protection The EVX-2 is equipped with thermal shutdown protection to guard against overheating caused by excessive current flow. If the operating temperature exceeds safe limits, the EVX-2 will automatically shut down and the EVX-2 LED will flash red. The LED on the face of the EVX- 2 will continuously flash red, even if the throttle trigger is moved back and forth. After the speed control cools down to a safe level, the LED will continuously shine green. The EVX-2 will once again function normally. EVX-2 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.

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.. Do not continue to operate the model with low batteries or you could lose control of it. Indications of low battery power include slow operation and sluggish servos (slow to return to center). Stop immediately at the first sign of weak batteries. When the batteries in the transmitter become weak, the red power light will begin to flash. Stop immediately and install new batteries. Do not drive the model at night, on public streets, or in large crowds of people. If the model becomes stuck against an object, do not continue to run the motors. Remove the obstruction before continuing. Do not push or pull objects with the model. Because the model is controlled by radio, it is subject to radio interference from many sources beyond your control. Since radio interference can cause momentary losses of control, allow a safety margin of space in all directions around the model in order to prevent collisions. Use good, common sense whenever you are driving your model. Intentionally driving in an abusive and rough manner will only result in poor performance and broken parts. Take care of your model so that you can enjoy it for a long time to come. High performance vehicles produce small vibrations which may loosen hardware over time. Frequently check wheel nuts and other screws on your vehicle to ensure that all hardware remains properly tightened. 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. Another major factor which affects run time is how the model is driven. Run times may decrease when the model is driven repetitively from a stop to top-speed and with repetitive hard acceleration. Tips for Increasing Run Time Use batteries with the highest mAh rating you can purchase. Use a high-quality peak-detecting charger. Read and follow all maintenance and care instructions provided by the manufacturer of your batteries and charger. Keep the EVX-2 cool. Get plenty of airflow across the ESC heat sinks. Lower your gear ratio. Installing smaller pinion gears will lower your gear ratio and cause less power draw from the motors and batteries, and reduce overall operating temperatures. Always replace both pinion gears together. Vary your speed. Continuous high-speed, high-gear running shortens the run time on the E-Maxx. Maintain your model. Do not allow dirt or damaged parts to cause binding in the drivetrain. Keep the motors clean. mAh Ratings and Power Output The mAh rating of the battery can effect your top speed performance. The higher capacity battery packs experience less voltage drop under heavy load than low mAh rated packs. The higher voltage potential allows increased speed until the battery begins to become discharged. Running in Wet Conditions Your new Traxxas E-Maxx 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 E-Maxx through puddles, wet grass, snow, and through other wet conditions. Though highly water resistant, the E-Maxx should not be treated as though it is submersible or totally, 100% waterproof. Water resistance applies only to the installed electronic components. Running in wet conditions requires additional care and maintenance for the mechanical and electrical components to prevent corrosion of metal parts and maintain their proper function. Precautions Without proper care, some parts of your model can be seriously damaged due to contact with water. Know that additional maintenance procedures will be required after running in wet

Driving Your Model conditions in order to maintain the performance of your model. Do not run your model in wet conditions if you are not willing to accept the additional care and maintenance responsibilities. Not all batteries can be used in wet environments. Consult your battery manufacturer to see if their batteries can be used in wet conditions. Do not use LiPo batteries in wet conditions (note: the EVX-2 is not LiPo compatible). 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. Do NOT allow your model to come in contact with salt water (ocean water), brackish water (between fresh water and ocean water), or other contaminated water. Salt water is highly conductive and highly corrosive. Use caution if you plan to run your model on or near a beach. Even casual water contact can reduce the life of your motors. Special care must be taken to modify your gearing and/or your driving style in wet conditions to extend the life of the motors (details below). Before Running Your Vehicle in Wet Conditions 1. Consult the section “After Running Your Vehicle in Wet Conditions” before proceeding. Make sure you understand the additional maintenance required with wet running. 2. The wheels have small holes molded in to allow air to enter and exit the tire during normal running. Water will enter these holes and get trapped inside the tires if holes are not cut in the tires. Cut two small holes (4mm or 3/16” diameter) in each tire. Each hole should be near the tire centerline, 180 degrees apart. 3. Confirm that the RX box O-ring and cover are installed correctly and secure. Make sure the screws are tight and the blue O-ring is not visible protruding from the edge of the cover. 4. Confirm that your batteries can be used in wet conditions. 5. Use lower gearing (smaller pinion gears, as low as 12T) when running in mud, deep puddles, snow, or other similar situations that will restrict the tires and put much higher loads on the motors.

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 bearings: Remove, clean, and re-oil the bearings. • Front and rear differential: Remove, disassemble, clean, and re-grease the differentials. Refer to your exploded view diagrams for help with disassembly and reassembly. • Transmission: Remove, disassemble, clean, and re-grease the transmission components. Use a light coating of wheel bearing grease (from an auto parts store) on the metal gear teeth. No grease is required for the nylon gears. Refer to your exploded view diagrams for help with disassembly and reassembly. • Titan motors: Remove the motors, clean with aerosol motor cleaner, and re-oil the bushings with lightweight motor oil. Be sure to wear eye protection when using spray aerosol cleaners. 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 two 3x10mm button-head cap screws. 2. To remove the receiver from the box simply lift it out and set to the side. The antenna wire is still inside the clamp area and cannot be removed yet. 3. Remove the wire clamp by removing the two 2.8x8mm cap screws. 4. Unplug the servo cables from the receiver and remove the receiver. Receiver Installation 1. Always install the wires into the RX box before installing the receiver. 2. Install the antenna wire and the servo cables into the receiver box. 3. Arrange the wires neatly using the wire guides in the receiver box. The excess wire will be bundled inside the receiver box. Label which wire is for which channel. 4. Apply small bead of silicone grease (Traxxas part #1647) to the wire clamp. 5. Install the wire clamp and tighten the two 2.8x8mm cap screws securely. 6. Install the receiver into the box and plug the wires into receiver. Refer to page 9 for the wiring diagram. 7. Make sure the O-ring is properly seated into the groove in the receiver box so that the cover will not pinch it or damage it any way. 8. Install the cover and tighten the two 3x10mm button-head cap screws securely. 9. Inspect the cover to make sure that the O-ring seal is not visible. Driving Your Model

Tuning Adjustments Suspension Tuning Adjusting the Pivot Ball Caps The pivot ball caps should be adjusted so that the pivot balls operate freely in the axle carriers with no excess play. Use the provided four-way suspension multi-tool to tighten or loosen the pivot ball cap. Caster Adjustment The E-Maxx offers the ability to adjust the caster angle of the front suspension. Caster adjustment may be used to influence the understeer/ oversteer handling characteristics of the E-Maxx. Increasing the caster angle will increase the tendency of the truck to oversteer (less traction on the rear tires, more traction on the front tires), while decreasing the caster angle will cause the truck to have a tendency to understeer (push in the turns). This effect becomes more pronounced at higher steering angles and higher spring rates. Caster is adjusted by repositioning the shims on the pivot point of the upper suspension arms. The stock caster setting is 7-degrees with one shim at each end of the arm. Reduce the caster angle to 4-degrees by removing the rear shim and inserting it next to the front shim. The caster angle can be increased to 10-degrees by removing the front shim and inserting it next to the rear shim. Fine Tuning the Shocks The eight shocks (oil dampers) on your E-Maxx have tremendous influence on its handling. Whenever you rebuild your shocks, or make any changes to the pistons, springs or oil, always do it carefully and in sets (front or rear). Piston head selection depends on the range of oil viscosities that you have available. For example, using a two-hole piston with lightweight oil will give you the same damping as a three-hole piston with heavier oil. We recommend using two-hole pistons w a range of oil viscosities from 30W to 50W (available from your hobby shop). The thin viscosity oils (30W or less) flow with less resistance and provide less damping, whil thicker oils provide more damping. Use on 100% pure silicone shock oil to prolong se From the factory, the E-Maxx uses 30W oil The ride height for the E-Maxx can be adju by adding or removing the clip-on spring load spacers. Note that changes in ride he will occur when changes in shock angle o rates are made. You can compensate for r height changes by changing the pre-load on the shocks Shock Mounting Positions Big bumps and rough terrain require a sof maximum possible suspension travel and prepared track or on-road use requires a lo more progressive suspension settings. The settings help reduce body roll (increased r braking, and squat during acceleration. Upper shock mounting position (A) should generally be used with lower shock mounting positions 1 and 2. Upper shock mounting position (B) should be generally be used with lower shock mounting positions 3 and 4. The innermost upper shock mounting position (0) can be used for tuning with the inner pair of lower shock mounting positions on the arm (1,2). It is not compatible with lower shock mounting positions 3 and 4. Other combinations may be used to achieve individualized suspension settings. Caster adjustment shims (1 Front, 1 Rear) Caster adjustment shims (2 Front) Caster adjustment shims (2 Rear) Vertical 4 Ground plane 7 Vertical Ground plane Vertical Ground plane 10 For easier access to the rear-most shock mounting screw, remove the one end of the rear turnbuckle. In the front, remove the suspension pin from the lower front suspension arm to gain easier access to the lower shock mounting screws.

In the out-of-the-box configuration, the shocks are installed in position (A) on the shock tower and position (2) on the lower suspension arm. This setting allows for firm suspension and low ride height, increasing the spring force (at the wheel). This setting improves high-speed cornering on smoother terrain by lowering the center of gravity. Body roll, brake dive, and squat are also reduced. The inner pair of holes on the lower suspension arm should be used to increase the ride height of the E-Maxx. The more vertical position of the shocks will allow for lower shock progression and the soft, plush feel that’s characteristic of a Traxxas Maxx Truck. Spring rate (at the wheel) increases as the lower shock mounting position is moved from position (1) to position (4). This is equivalent to using stiffer springs. Use higher spring rate settings for flatter terrain with smaller and fewer bumps, and lower spring rate settings for bigger bumps. Ride height decreases as the lower shock mounting position is moved from position (1) to position (4). Each pair of lower shock mounting holes (1,2 and 3,4) has equal ride height. Use lower ride height for high-speed cornering and flat terrain, and when racing on relatively smooth tracks. Increase the ride height for rougher terrain and tracks. Upper Shock Mounting Positions The upper shock mounting positions will have suspension effects opposite from the lower shock mounting positions. Spring rate (at the wheel), increases as the upper shock mounting position is moved from position (A) to position (B). Ride height is not affected by changes in the upper shock mounting position. Use the chart below to see the effect of the various shock mounting positions. The horizontal length of the lines indicates the amount of suspension travel. The angle or slope of the lines indicates the spring rate (at the wheel). 2.5 2 1.5 1 0.5 0 0 10 20 30 40 60 70 80 90 100 50 Wheel Force (lb) Wheel Travel (mm) Wheel Force vs. Wheel Travel Lower Mount 1, Upper Mount 0 Lower Mount 2, Upper Mount 0 Lower Mount 1, Upper Mount A Lower Mount 2, Upper Mount A Lower Mount 3, Upper Mount A Lower Mount 4, Upper Mount A Lower Mount 1, Upper Mount B Lower Mount 2, Upper Mount B Lower Mount 3, Upper Mount B Lower Mount 4, Upper Mount B Less Firm More Firm Lower Mount 4 Lower Mount 3 Lower Mount 2 Lower Mount 1 Tuning Adjustments

Tuning Adjustments 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 counter- clockwise ¼ to ½ turn. ;gdcid[IgjX` AZ[i=VcYI]gZVY >cY^XVidg ;gdcid[IgjX` AZ[i=VcYI]gZVY >cY^XVidg AZ[iH^YZ G^\]iH^YZ All of the toe links are installed on the truck so that the left hand thread indicators point to the same direction. This makes it easier to remember which way to turn the wrench to increase or decrease toe link length (the direction is same at all four corners). Note that the groove in the hex indicates the side of the toe link with the left-hand threads. Alignment Settings Adjusting the Toe-in Your E-Maxx comes from the factory with zero degrees of toe-in in the front, and one degree of toe-in in the rear. You can adjust the toe-in on the front and rear of the truck. Set the steering trim on your transmitter to neutral. Next, adjust your steering turnbuckles so that both front wheels are pointing straight ahead and are parallel to each other (0 degrees toe- in). This will ensure the same amount of steering in both directions. Adjust the rear toe control links so that the rear wheels have 1˚ of toe-in. Static Camber Adjustment The wheels can be set to have either positive or negative camber (see illustration below). The camber angle changes as the wheel moves up and down through its range of travel. Static camber is the camber angle at the wheel when the vehicle is set at its normal, stationary ride height. The suspension pivot balls located in the axle carriers adjust the static camber. The pivot balls are protected by blue dust plugs. To adjust your static camber, insert the supplied 2.5mm hex wrench through the slit in the dust plug and engage the end of the pivot ball (compressing the suspension until the arms are parallel to the ground will allow for easier hex wrench engagement). The upper pivot ball is normally screwed all the way in. Negative camber is achieved by screwing the pivot ball of the lower control arm out. Note: When camber is changed, the toe angle of the wheel has to be reset. Static Camber Base Factory Settings Front: 1-degree negative camber each side Rear: 1-degree negative camber each side Transmission Tuning Adjusting the Slipper Clutch The E-Maxx 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 regulate the amount of power sent to the rear wheels to prevent tire spin. W it slips, the slipper clutch makes a high-p whining noise. To adjust the slipper clutch, remove the slipper clutch plug on the transmission c integrated into the main spur gear on th clutch is adjusted using the spring-loade shaft. Use the supplied universal wrench slipper nut, insert the 2.0mm hex wrench of the slipper shaft. This locks the shaft fo adjustment nut clockwise to tighten (les clockwise to loosen (more slippage).

The Titan™ 550 Motors on your E-Maxx have been carefully designed to match the needs of the E-Maxx. The Titans are made to run efficiently at high voltage to provide more torque and longer run times. We do not recommend converting the E-Maxx to a typical low voltage setup using traditional 540 size motors. While these components will physically fit into the E-Maxx, the system will not run as efficiently, losing power in the form of motor and battery heating. The result will be shorter run times, high current draw, and extreme battery and motor temperatures. If you are considering replacement motors, look for 550 motors capable of 12 or more volts. The E-Maxx is equipped from the factory with a 68-tooth spur gear and 19-tooth pinion gears. E-Maxx 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. Higher numerical ratios provide more torque, lower numerical ratios provide more top speed. With the Titan motors, do not use a pinion gear larger than 20-tooth with the stock 68- tooth spur gear with 6-cell battery packs or a pinion gear larger than 19-tooth with the stock 68-tooth spur gear when using 7-cell battery packs. Use the following formula to calculate the overall ratio for combinations not listed on the gear chart: Going Brushless Brushless motors provide increased power output and greater efficiency. The E-Maxx is designed with extra transmission and driveline strength to make it capable of handling extreme brushless power. One or two brushless motors may be used. A specially designed motor plate (part # 3997X) and gear cover (part # 3977X) are available for optimized, single-motor installations. If you plan to run LiPo battery packs to power a LiPo-compatible brushless system, optional battery hold downs (part # 3927X) are available to accommodate larger, high capacity 2S and 3S LiPo battery packs. For the ultimate in extreme brushless speed and acceleration, install twin Velineon power systems (part number 3350). Two Velineon brushless motors powered by two Velineon VXL-3s speed controls in tandem results in amazing power output. Visit www.Traxxas.com for more details about power upgrades. Adjusting Gear Mesh Incorrect gear mesh is the most common cause of stripped spur gears. Gear mesh should be checked and adjusted anytime a gear is replaced. Access the gears by removing the single screw on the top gear cover. To set the gear mesh, cut a narrow strip of notebook paper and run it into the gear mesh. Loosen the motor screws and slide a motor and pinion gear into the spur gear. Retighten the motor screws and then remove the strip of paper. Repeat with the other motor. You should be able to run a fresh strip of paper through the gears without binding them. Dual Steering System Your new E-Maxx uses dual-servo steering and a single heavy-duty servo saver for powerful, responsive steering. To prevent damage to the steering servos, it is important to make sure that the servos are “at rest” when the steering is at neutral. If one servo is out of adjustment, then both servos will work against each other, fighting to find center. # Spur Gear Teeth x 5.22 = Final Gear Ratio # Pinion Gear Teeth Tuning Adjustments Motor Screws Strip of Paper Pinion Gear 2 2 2 Servo Saver Center Drag Link Servo Horn Servo Horn Toe Link Toe Link Bellcrank

Adjusting the Steering System 1. Disconnect the short steering link that connects the servo saver to the servo horn. 2. Remove the drag link that connects the two servo horns. 3. Remove the servo horns 4. Connect a pair of charged batteries to the ESC. Turn on the transmitter, then the ESC. Note: It is recommended to unplug the motors or remove the pinion gears during steering setup. 5. Adjust the steering trim on the transmitter to the neutral “0” position. 6. Install both servo horns. Make sure they are parallel to the center line of the chassis (pointing to the rear of the truck). 7. Connect the short steering link from the servo saver to the servo horn. Make sure the servo saver is parallel to the center line of the chassis (also parallel to the servo horns). If not, make small adjustments to the length of the link so the everything is parallel. 8. The steering should operation correctly with equal travel left and right. Now connect the second servo. 9. Confirm the length of the center drag link (89.5mm - see template, below). 10. Connect the center drag link to one Check for alignment with the holes If these do not line up, make small a the link until the holes line up. 11. Connect the center drag link to the servo horn. 12.

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. Check the tightness of the wheel nuts with a wrench. 7. Check the operation of the radio system, especially the condition of the batteries. 8. Check for any loose screws in the chassis structure or suspension. 9. Inspect the gears for wear, broken teeth, or debris lodged between the teeth. 10. Check the tightness of the slipper clutch. 11. Check the tightness of the front pivot balls. Other periodic maintenance: Slipper clutch pads (friction material): Under normal use, the friction material in the slipper clutch should wear very slowly. If the thickness of any one of the slipper clutch pads is 1.8mm or less, the friction disc should be replaced. Measure the pad thickness using calipers or measuring against the diameter of the 1.5 and 2.0mm hex wrenches provided with the model. Chassis: Keep the chassis clean of accumulated dirt and grime. Periodically inspect the chassis for damage. Motors: Every 10-15 runs, remove, clean, and lubricate the motors. Use a product such as electric motor cleaning spray to flush dirt out of the motors. After cleaning, lubricate the bushings at each end of the motors with a drop of light-weight electric motor oil. Shocks: Keep the oil level in the shocks full. Use only 100% pure silicone shock oil to prolong the life of the seals. If you are experiencing leakage around the top of the shock, inspect the bladder in the top cap for signs of damage or distortion from overtightening. If the bottom of the shock is leaking, then it is time for a rebuild. The Traxxas rebuild kit for two shocks is part #2362. Suspension: Periodically inspect the model for signs of damage such as bent or dirty suspension pins, bent turnbuckles, loose screws, and any signs of stress or bending. Replace components as needed. Driveline: Inspect the driveline for signs of wear such as worn drive yokes, dirty axle half shafts, and any unusual noise or binding. Remove the gear cover and Inspect the spur gear for wear and check the tightness of set screws in the pinion gears. Tighten, clean, or replace components as needed. Storage When you are through running the model for the day, blow it off with compressed air or use a soft bristled paint brush to dust-off the vehicle. Always disconnect and remove the batteries from the model whenever the model is stored. If the model will be stored for a long time, then also remove the batteries from the transmitter.

Troubleshooting The following section addresses some very basic ESC and radio questions you may have about your model. Most questions arise from simple user errors or minor adjustments that are easy to correct. If you can’t find a solution for your model here, then visit our website at www.Traxxas. com/support. There you will find a much more extensive and detailed online troubleshooting area. In addition, you may call Traxxas Customer Service at 1-888-TRAXXAS (outside the US call 972-265-8000). Radio system does not work properly: If the power light on the transmitter does not come on, check for proper battery installation and that the batteries are new and/or fully charged. If the power light is blinking, then the transmitter batteries are weak and should be replaced. See page 11 for more details. If the transmitter light is on but the radio is still not responding, check for proper installation of batteries in the model and that the batteries are new and/or fully charged. Check to make sure the on/off switch on the model is in the on position. Check for damaged wires, a loose crystal, or loose connections. See page 11 for more details. Short radio range: If the radio range appears short, then first check to make sure the transmitter antenna is fully extended and that the antenna in the model is in place and has not been cut or damaged. Next, make sure the batteries are all fully charged. Finally, if you are still experiencing short range, try a different location. Sometimes there can be interference from various sources that can cause your radio to malfunction. Steering channel works, but the motor(s) will not run: The motor(s) could be bad or have a damaged brush. Check the motor(s) and motor connections by supplying power directly to the motor(s). Note: Disconnect the motor(s) from the ESC before testing. Remove the pinion gear from the motor(s) or elevate the driving wheels to avoid a runaway and damage to the vehicle. The speed control has thermally shut down (look for a solid green LED). Allow the speed control to cool down. See the overheating section. Make sure the EVX-2’s power cable is plugged into the throttle channel of the receiver (Channel 2). Check the operation of the radio system’s throttle channel with a servo. Possible internal damage. Contact Traxxas for service. EVX-2 will not go into programming mode: Make sure the EVX-2 is plugged into Channel 2 (the throttle channel) on the receiver. If it is plugged into Channel 3 or the battery terminal, it will not go into programming mode. Be sure the EVX-2 is turned off before trying to program or select a profile. Unplug batteries, reconnect, and repeat programming instructions. Steering servos do not work: Check the wires, radio system, crystals, ba and the battery packs. Possible internal damage.
