1. Product Overview
This manual provides detailed information for the installation and maintenance of the BMLZHO Brass Counterweight Fittings designed for FYikong 4106 and YK4107 1/10 scale RC remote control cars. These components are engineered to enhance the stability and performance of your RC vehicle by adding strategic weight.
The set includes various brass components with a black edge process, specifically designed for the front axle steering cup, rear wheel seat, beam, and front/rear wheels.
2. Product Components
The complete set of brass counterweight fittings includes the following components:
- Front Axle Steering Cup Gear Cover: Approximately 215g. Designed to add weight to the front steering assembly.
- Rear Wheel Seat Gear Cover: Approximately 185g. Adds weight to the rear wheel assembly.
- Beam Counterweight: Approximately 240g. For central weight distribution.
- Front Wheel Weight Block: Approximately 205g. Specific weights for the front wheels.
- Rear Wheel Weight: Approximately 130g. Specific weights for the rear wheels.
- Front and Rear Pull Rods (8 pieces): Approximately 156g total.
All components are made from brass with a durable black edge plating process.

3. Setup and Installation
Installation of these brass counterweights requires basic RC car assembly knowledge and tools. It is recommended to refer to your RC car's original manual for specific disassembly and reassembly procedures of the axle and wheel seat areas.
- Preparation: Ensure your RC car is powered off and the battery is disconnected. Gather necessary tools such as screwdrivers, pliers, and any specific tools required for your FYikong model.
- Disassembly: Carefully remove the existing steering cup, wheel seat, and any relevant beam components from your RC car. Keep track of all screws and small parts.
- Component Replacement: Replace the original components with the corresponding brass counterweight fittings. Ensure proper alignment and fit.
- Secure Fasteners: Use the provided screws or the original screws (if compatible and recommended by your RC car's manual) to securely fasten the new brass parts. Do not overtighten.
- Reassembly: Reassemble the RC car's axle and wheel seat assemblies, ensuring all connections are secure and moving parts operate freely.
- Testing: After reassembly, manually check the steering and wheel rotation for any binding or obstruction before powering on the vehicle.

4. Operating Considerations
The primary function of these brass counterweights is to lower the center of gravity and increase the overall weight of your RC car. This can lead to improved stability, better traction, and enhanced crawling performance, especially on uneven terrain.
- Performance Impact: Expect a noticeable change in the vehicle's handling characteristics due to the added weight. This is generally beneficial for crawling and low-speed control.
- Motor and ESC: While these parts are passive, significant increases in vehicle weight can put additional strain on the motor and Electronic Speed Controller (ESC). Monitor temperatures during initial runs.
- Suspension: The added weight may cause the suspension to compress more. Adjust spring rates or shock oil if necessary to maintain desired ride height and damping.
5. Maintenance
These brass components are designed for durability. Regular maintenance will ensure their longevity and optimal performance.
- Cleaning: Periodically clean the brass parts to remove dirt, dust, and debris. A soft brush or cloth can be used. Avoid harsh chemicals that may damage the plating.
- Inspection: Regularly inspect the components for any signs of wear, damage, or loose fasteners. Tighten any loose screws as needed.
- Corrosion: While brass is resistant to corrosion, prolonged exposure to moisture or corrosive substances can affect the finish. Dry the parts thoroughly after use in wet conditions.
6. Troubleshooting
Most issues related to these parts will stem from improper installation or pre-existing issues with the RC vehicle.
| Problem | Possible Cause | Solution |
|---|---|---|
| Binding or Stiff Steering | Incorrect installation of steering cup; overtightened screws; debris. | Recheck steering cup alignment; loosen screws slightly; clean area. |
| Wheels not spinning freely | Improper installation of wheel seat; bearing issues; overtightened wheel nuts. | Verify wheel seat installation; inspect bearings; adjust wheel nut tightness. |
| Unusual Noise from Axle/Wheel Area | Loose components; foreign object; damaged gear. | Inspect all fasteners; remove debris; check gears for damage. |
