4. Setup and Assembly
Follow the detailed steps in the included user manual for precise assembly. Below are general guidelines and key areas of focus.
4.1 Chassis Assembly
Begin by assembling the FRP double-deck chassis. Ensure all screws are tightened securely but do not overtighten to avoid stripping plastic parts. Pay close attention to the 1.5mm thick FRP T-bar design with its U-shaped cutaway, which is crucial for chassis flexibility and handling.

4.3 Rear Assembly and Drivetrain
Install the motor and connect it to the electronic speed control (ESC). Assemble the aluminum ball differential, ensuring it operates smoothly. Attach the rear wheels and the rear wing assembly.
4.4 Electronics Installation and Wiring
Mount the receiver, ESC, and battery securely. Route all wiring neatly to prevent interference with moving parts and to maintain a clean appearance. Ensure all electrical connections are correct before powering on the vehicle.
5. Operating Instructions
Once assembled and all electronics are properly connected and calibrated, you can begin operating your Tamiya F104 Pro II.
- Pre-Run Check: Before each use, inspect all screws, linkages, and connections. Ensure the battery is fully charged and securely installed.
- Transmitter Pairing: Follow your radio system's instructions to pair the transmitter with the receiver.
- Power On Sequence: Always turn on the transmitter first, then the RC car. When finished, turn off the RC car first, then the transmitter.
- Driving: Start with gentle throttle inputs to get a feel for the car's handling. The F104 Pro II is a 2WD vehicle, offering a sharp and responsive driving feel.
- Braking: Use the brake function on your transmitter to slow down or stop the vehicle.
6. Maintenance
Regular maintenance will prolong the life and performance of your RC car.
- Cleaning: After each run, clean dirt and debris from the chassis, suspension, and drivetrain using a soft brush or compressed air.
- Inspection: Regularly check for loose screws, worn gears, damaged suspension components, and cracked tires. Replace any damaged parts promptly.
- Lubrication: Apply appropriate lubricants to moving parts as recommended in the detailed manual.
- Ball Differential: Periodically inspect and maintain the aluminum ball differential for smooth operation.
- Battery Care: Store batteries in a cool, dry place. Do not overcharge or over-discharge LiPo batteries.
7. Troubleshooting
Refer to this section for common issues and their solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Car does not respond to controls | Low battery in car or transmitter, un-paired radio, loose connections, ESC not armed. | Charge batteries, re-pair radio, check all wiring, arm ESC according to its manual. |
| Car runs slowly or lacks power | Low battery, motor issues, gear mesh too tight, binding drivetrain. | Charge battery, inspect motor and gears, adjust gear mesh, check for free movement of drivetrain components. |
| Steering is erratic or unresponsive | Loose servo horn, damaged servo, incorrect trim settings, binding steering linkages. | Check servo horn, inspect servo, adjust steering trim, ensure smooth movement of steering components. |
| Unusual noises during operation | Damaged gears, worn bearings, foreign object in drivetrain. | Inspect gears and bearings, remove any obstructions, replace damaged parts. |
