3. Assembly Instructions

This chassis is designed for DIY assembly. Please follow these general steps. Refer to detailed diagrams or specific instructions provided with your motor, ESC, and other electronic components for a complete build.

1. Prepare Your Workspace: Ensure a clean, well-lit area with all tools readily accessible. Organize all parts from the kit.
2. Chassis Base Assembly: Begin by attaching the main suspension arms and differential housings to the carbon fiber chassis plate. Ensure all screws are tightened securely but do not overtighten.
3. Shock Absorber Installation: Install the four shock-absorbing struts onto the suspension towers. Ensure they are properly oriented and move freely.
4. Drive Shafts and Axles: Assemble the metal drive shafts and connect them to the differential outputs and wheel axles. Verify smooth rotation.
5. Motor Mount and Steering Assembly: Attach the aluminum alloy motor base to the chassis. Install the steering servo and connect the steering linkages. Ensure the steering mechanism operates smoothly without binding.
6. Wheel and Tire Installation (if applicable): If your kit includes wheels and tires, mount them onto the axles.
7. Final Inspection: Before installing electronics, perform a thorough inspection. Check all screws for tightness, ensure all moving parts operate smoothly, and confirm there is no excessive play in any joints.

4. Setup and Calibration

Once the chassis is assembled, the next steps involve installing and calibrating your RC car's electronics (motor, ESC, servo, receiver, battery). These steps are crucial for optimal performance.

• Motor and ESC Installation: Securely mount your chosen motor to the aluminum motor base. Connect the motor to the Electronic Speed Controller (ESC) according to the ESC manufacturer's instructions.
• Servo Installation: Install the steering servo into its designated mount. Connect the servo horn to the steering linkages.
• Receiver and Battery Placement: Mount the receiver in a secure location, away from electrical interference. Place the battery in its tray, ensuring it is balanced for optimal weight distribution.
• Radio System Binding and Calibration: Bind your receiver to your transmitter. Calibrate the ESC and servo endpoints according to their respective manuals to ensure full range of motion and proper throttle response.
• Suspension Tuning: Adjust the shock absorbers and spring tension to suit your driving style and terrain. Ensure equal ride height on all four corners.
• Wheel Alignment: Check and adjust toe-in/toe-out settings for optimal steering response and tire wear.

5. Operating Guidelines

While this product is a chassis, its proper operation depends on the complete RC vehicle build. Always adhere to general RC operating safety guidelines.

• Pre-Run Checks: Before each use, inspect all screws for tightness, check battery charge, and ensure all electronic connections are secure.
• Safe Operating Environment: Operate your RC vehicle in open areas, away from people, pets, and obstacles. Avoid public roads.
• Battery Safety: Always use appropriate chargers for your battery type. Never leave charging batteries unattended. Disconnect batteries when not in use.
• Avoid Overheating: Monitor motor and ESC temperatures during operation. Excessive heat can damage components.
• Post-Run Care: After use, clean the chassis of dirt and debris. Inspect for any damage or loose parts.

6. Maintenance

Regular maintenance will extend the lifespan and performance of your RC chassis.

• Cleaning: After each run, especially in dusty or dirty conditions, clean the chassis using a soft brush or compressed air. Avoid water directly on electronics.
• Screw Checks: Periodically check all screws and fasteners for tightness. Vibrations can cause them to loosen over time.
• Bearing and Bushing Inspection: Inspect bearings and bushings for smooth operation. Replace any that feel gritty or show excessive play.
• Shock Absorber Maintenance: Check shock oil levels and seals. Refill or replace as needed to maintain consistent damping.
• Drive Train Inspection: Examine drive shafts, gears, and differentials for wear or damage. Lubricate moving parts as recommended by your specific component manufacturers.
• Tire and Wheel Inspection: Check tires for wear and tears. Ensure wheels are securely mounted and not warped.
