Traxxas RUSTLER 4x4 67064-1

This manual describes the Traxxas Rustler 4X4, a 1/10-scale electric stadium truck designed for off-road excitement and high-speed performance. It comes equipped with a powerful Titan 12T 550 motor and a smooth XL-5 electronic speed control, ensuring durability and long-lasting operation. The model features new wheels and tires with advanced tread patterns and rubber compounds for superior driving. Innovative technology, such as the patent-pending Torque-Control slipper, is incorporated from Traxxas' top-of-the-line Revo models.

The Rustler 4X4 is controlled by a Traxxas TQ 2.4GHz radio system, which automatically locates and locks onto an available frequency, allowing multiple models to be raced without interference. The transmitter has two channels: one for steering and one for throttle. The receiver in the model has three output channels, with one servo and an electronic speed control connected. The radio system is factory-programmed for correct operation, but adjustments can be made for optimal performance. The transmitter requires four AA alkaline or rechargeable batteries (sold separately).

The model features an innovative latching system for securing the body to the chassis, allowing for easy removal and installation. To remove the body, the handle is turned 90 degrees counterclockwise to unlock the latch, which then releases the truck body from the rear shock tower. The body slides backward to release the front tab and can then be gently lifted straight up from the chassis.

The electronic speed control (ESC) is a powerful device capable of delivering high current. It has a 15-turn modified motor limit for 540-size motors and a 12-turn modified motor limit for 550-size motors with 0 timing. The ESC is designed to be used with 4-7 NiMH cells or 2 LiPo cells (2s) only, with a maximum input voltage of 8.4 volts (NiMH) or 7.4 volts (2s LiPo). It is crucial to use neutrally timed motors (0° timing) for reverse operation to prevent excess current draw and overheating. Three 0.1µF (50V) ceramic capacitors are required for the motor to prevent radio interference. The ESC is not compatible with external Schottky diodes.

The XL-5 electronic speed control is equipped with built-in Low-Voltage Detection, which monitors battery voltage. When LiPo battery voltage reaches its minimum discharge threshold, the XL-5 limits power output to 50% throttle. If the voltage drops further, the motor output shuts down, indicated by a slowly blinking red LED. This feature is disabled by default for NiMH batteries but must be activated when using LiPo batteries. The XL-5 offers three driving profiles: Sport Mode (100% Forward, 100% Brakes, 100% Reverse), Race Mode (100% Forward, 100% Brakes, No Reverse), and Training Mode (50% Forward, 100% Brakes, 50% Reverse). Training Mode is particularly useful for beginning drivers to improve control.

The model is designed with water-resistant features to protect the electronics, allowing operation in puddles, wet grass, and snow. However, it is not fully submersible, and additional care and maintenance are required after wet conditions to prevent corrosion. The Traxxas TQ 2.4GHz transmitter is not water resistant and should not be exposed to wet conditions.

Maintenance is crucial for the Rustler 4X4 to remain in top running condition. Regular inspection for cracked, bent, or damaged parts, binding in the wheels and steering, and proper shock absorber operation is recommended. Wiring should be checked for fraying or loose connections, and the mounting of the receiver, servos, and speed control should be secure. Wheel nuts should be tight, and the radio system's operation, especially battery condition, should be verified. Loose screws in the chassis or suspension should be addressed, and the steering servo should operate freely without binding. Gears should be inspected for wear, broken teeth, or debris. The slipper clutch tightness should also be checked.

Periodic maintenance includes inspecting the slipper clutch pads for wear; if any pad is 1.8mm or less, it should be replaced. The chassis should be kept clean of dirt and grime. Over time, increased looseness in the steering system may occur due to wear in bellcrank bushings and tie rod ends, which should be replaced as needed. The motor should be removed, cleaned with an aerosol motor cleaner, and lubricated with lightweight electric motor oil every 10-15 runs. Shock oil levels should be kept full with 100% pure silicone shock oil, and rebuilds should be performed if leakage occurs. The driveline should be inspected for wear, unusual noise, or binding.

The model's front and rear gear differentials can be tuned for different driving conditions by changing the viscosity of the silicone oil. From the factory, the front differential is filled with SAE 30,000W viscosity silicone oil, and the rear differential is filled with grease. Higher viscosity oil reduces power transfer to wheels with less traction, which can be beneficial for climbing or racing on low-traction surfaces. The differentials must be removed from the vehicle and disassembled to change the oil.

The slipper clutch is adjustable and built into the large spur gear. It regulates power to the wheels to prevent tire spin. To adjust, the slipper gear assembly is removed, and the adjusting nut is turned clockwise to tighten or counterclockwise to loosen. A good starting point is to tighten the nut until the spring fully collapses, then turn it counterclockwise one full turn. The manual advises against running the model with the slipper clutch adjusting spring fully compressed.

The model's suspension can be adjusted for different terrains. For off-road performance, the factory setting uses position 2 on the front suspension arms and position 3 on the rear. For hard surfaces, it's recommended to move front shocks to position 3, rear shocks to position 4 or 5, and add preload spacers. The four shocks greatly influence handling, and any changes to pistons, springs, or oil should be made in pairs (front or rear). The model's ride height can be adjusted using clip-on spring preload spacers.

When storing the model, the battery should always be disconnected and removed. For long-term storage, batteries should also be removed from the transmitter.
