4. Negative Camber 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 When it slips the slipper clutch makes a high pitch whining noise Tighten Loosen To adjust the slipper clutch remove the rubber slipper clutch plug on the transmission cover The slipper clutch is integrated into the main spur gear on the transmission The slipper clutch is adjusted using the spring loaded locknut on the slipper shaft Use the supplied universal wrench To tighten or loosen the slipper nut insert the 2 0mm hex wrench into the hole in the end of the slipper shaft This locks the shaft for adjustments Turn the adjustment nut clockwise to tighten less slippage and counter clockwise to loosen more slippage Many types of aftermarket tires and wheels can be adapted for use on your model Most will affect the overall width and the suspension geometry of the model The offsets and dimensions designed into the model s wheels are intentional therefore Traxxas cannot recommend the use of other non Traxxas wheels with different specifications The diameter of the wheels is an innovative design and there is a variety of different tires available for you to experiment with in addition to the included tires on the model listed in

E MAXX THE TRAXXAS TQ RADIO SYSTEM 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 CHANNEL FREQUENCY FLAG TRAXXAS BAND COLOR PART NO a 1 26 995 BROWN 2031 a 2 27 045 RED 2032 d 3 27 095 ORANGE 2033 EF 4 27 145 YELLOW 2034 a 5 27 195 GREEN 2035 a 6 27 255 BLUE 2036 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 Cont
7. long lasting and easy to grip the Traxxas connector is engineered to extract all the power your battery has to give To run this model your batteries must be equipped with Traxxas High Current Connectors Batteries can either be purchased new with Traxxas connectors installed or Traxxas connectors can be purchased to install on battery packs you already own See sidebar on page 13 for packages available from your hobby dealer The typical Molex style connector is inadequate for use in your model It creates resistance that becomes a bottleneck to current flow If your battery pack is equipped with a Molex connector it must be replaced with a Traxxas High Current Connector to mate with the EVX 2 electronic speed control Molex connector Brake Reverse Neutral Accelerate 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 THE TRAXXAS TO RADIO SYSTEM There are two settings available 50 50 Allows equal travel for both acceleration and reverse 70 30 Allows more throttle travel 70 swe an

10. when changes in shock angle or spring rates are made You can compensate for ride height changes by changing the pre load spacers on the shocks 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 progressive suspension settings The more progressive suspension settings help reduce body roll increased roll stiffness dive during 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 Lower Shock Mounting Positions 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 bra
11. your parts list Experimentation with different types of tires is recommended to see which ones work the best on the terrain where the model is run When selecting tires consider the overall diameter and the rubber compound hard or soft If the overall diameter of the tire is significantly increased you will need to use a smaller pinion gear to compensate for the larger tire Soft compound tires with many short spikes generally work better on hard dry surfaces In loose dirt a tire with large spikes should perform better See your parts list for accessory wheels and tires 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 acc
