Overview

This document serves as an instruction manual for the VKAR 1:10 Scale Electric 4WD Off-Road Race Truggy, named "Bison." It provides comprehensive guidance on operating, maintaining, and understanding the various components of this remote-controlled vehicle. The manual emphasizes the importance of reading through the instructions carefully to ensure proper use and to prevent damage or injury.

Function Description:

The Bison is a powerful 1:10 scale electric 4WD off-road race truggy designed for enthusiasts seeking an enjoyable and high-performance RC experience. Its 4-wheel drive system ensures excellent traction and control across various terrains, making it suitable for off-road racing and recreational driving. The truggy is equipped with an electronic speed control (ESC) that manages the motor's power output, allowing for precise throttle control. The included transmitter (controller) provides intuitive command over the truggy's steering and throttle, enabling users to navigate and maneuver the vehicle effectively. The model is fully assembled and "Ready-To-Run" (RTR), meaning it comes pre-built and largely prepared for immediate use after basic setup.

Usage Features:

The Bison boasts a range of features designed to enhance its performance and user experience:

  • Bright LED Light: For improved visibility, especially in low-light conditions or for adding a realistic touch.
  • Secure Wheelie Bar Set: Helps prevent the truggy from flipping backward during aggressive acceleration, allowing for controlled wheelies.
  • All Rubber Covered Bearing Throughout: Contributes to smoother operation, reduced friction, and increased durability by protecting the bearings from dirt and debris.
  • Adjustable Rear Wing: Allows users to fine-tune the aerodynamic downforce, which can impact stability and handling at high speeds.
  • Sealed, Tunable Limited-Slip Differentials: Provide improved traction and power distribution to the wheels, especially when one wheel loses grip. The tunability allows for customization of the differential action to suit different driving styles and track conditions.
  • All-Terrain Tires & Aggressive Electroplate Wheels: The tires are designed to offer excellent grip on various off-road surfaces, while the electroplate wheels provide a durable and visually appealing finish.
  • Oil-Filled Ultra AL Shocks with Progressive Dual-Springs: These high-quality shocks absorb impacts and smooth out rough terrain, providing a stable and controlled ride. The progressive dual-springs offer a variable spring rate, adapting to different levels of compression.
  • Fully Assembled and Ready-To-Run: This feature minimizes setup time, allowing users to quickly get the truggy operational.

The manual provides detailed instructions for installing the batteries in the transmitter, noting that AAA batteries are required. It also outlines the functions of the transmitter's various controls, including throttle trim, throttle dual-rate (D/R), steering trim, steering D/R, and the throttle trigger. The binding process for connecting the transmitter and receiver is clearly explained, ensuring a secure communication link between the controller and the truggy.

For electronic setup, the manual details how to connect the ESC, motor, receiver, battery, and servo. It emphasizes the importance of calibrating the throttle range to ensure proper functionality of the ESC with the transmitter. This calibration involves setting the neutral point, end point of forward direction, and end point of backward direction. The LED status indicators on the ESC are also explained, providing visual feedback on the truggy's operational state (e.g., neutral, forward, braking, reversing).

Safety warnings are prominently featured, advising users that the product is not a toy and that children under 14 should be supervised. It stresses the importance of checking battery charge levels, operating in spacious venues, and following the correct power-on/off sequence (transmitter first, then car; car off first, then transmitter). Users are also warned about the high heat generated by the ESC and motor during operation, advising against physical contact until the components have cooled.

Maintenance Features:

The manual includes several instructions and tips related to maintenance and care:

  • Battery Handling: Users are instructed to remove the battery from the RC car before charging, allow the battery to cool down before charging, and store it in a cool and dry place. This is crucial for the longevity and safety of Ni-MH or Lithium Polymer batteries, given their high energy density.
  • Checking Connections: The manual advises checking wires inside the car for any loose connections, which can prevent malfunctions and ensure consistent performance.
  • Slipper Clutch Adjustment: Detailed instructions are provided for adjusting the slipper clutch, a critical component that protects the drivetrain from damage during racing by allowing a controlled amount of slip. The manual warns that an improperly adjusted slipper clutch (too loose or too tight) can lead to gear damage. A "short cut" method for adjustment using a 1.5mm hex key is also described.
  • Motor Mount Assembly: The manual highlights the importance of rotating a specific nut to achieve the suitable degree of tightness for the motor mount. It also advises checking the interval between the motor gear and spur gear, and adjusting it if the screw is loosened.
  • Steering Assembly: Similar to the motor mount, the manual instructs users to rotate a specific nut in the steering assembly to achieve the correct tightness, ensuring precise steering control.
  • Shock Assembly: A step-by-step guide is provided for assembling the shocks, including filling them with silicone fluid, removing air bubbles, and installing the spring. This ensures optimal damping performance.
  • Differential Assembly: The manual includes a critical note to pay attention to the direction when installing the differential into the gearbox, as incorrect installation can lead to operational issues.
  • Spare Parts List: A comprehensive list of spare parts with their respective part numbers, specifications, and dosages (quantities) is provided. This allows users to easily identify and order replacement parts for repairs and maintenance, extending the lifespan of the truggy.
  • Exploded View Diagram: An exploded view diagram of the entire truggy is included, illustrating all components and their assembly order. This visual aid is invaluable for understanding the truggy's construction and for guiding disassembly and reassembly during maintenance or repairs.

Overall, the manual provides essential information for both novice and experienced RC enthusiasts to safely and effectively operate and maintain their VKAR Bison truggy.
