Wires & Tires
Connecting wires and adding your tires ensures that your remote control car not only receives the necessary power and signals for smooth operation, but provides systems for better maneuverability and control on various surfaces.
Part 1: Wires
To ensure accurate routing and connection of the wires in your vehicle with minimal errors, it is essential to gather the following materials beforehand: 1) a soldering kit, including solder and a soldering iron, 2) battery boxes, 3) the car's power switch, 4) the car remote, 5) a 9V bolt battery with a snap connector, and 6) a roll of electrical tape.
Implementation
Now that you have successfully mapped out your car body wires, it's time to begin the soldering process. If this is your first experience with soldering, please take a moment to review the following guide. First, ensure you are in a safe environment suitable for electrical work. Retrieve your soldering iron and solder wire, then plug the iron into a nearby outlet and allow it to heat to the appropriate temperature while preparing your solder wire.
Once the solder is adequately heated, take your twisted wires and fuse them together by applying the solder on top. If you accidentally connect the wrong wires, carefully use your wire cutters to disconnect them and try again. However, it's important to minimize excessive reconnections to avoid future malfunctions.
After all your car body wires are securely connected, repeat the process for your remote and battery. Finally, wrap all connections with electrical tape to ensure a stable flow of electricity. When you have completed your work, remember to clean your soldering iron and store your tools properly.
To begin, ensure that you securely install and properly position your vehicle's power switch and battery holders. If space or material constraints prevent this, temporary fasteners like tape may be used, but exercise caution regarding their placement. Before proceeding with soldering, it is crucial to map out the connections of each wire and document these positions upon twisting the ends together by hand.
Preparation
For the receiver, typically labeled with forward (F), backward (B), left (L), and right (R) controls, connect F and B to the driving motor and L and R to the steering motor to avoid improper remote functions. Lastly, connect the black wire from the left battery holder to V- and the red wire the right battery holder to V+, ensuring that the two remaining wires are joined together to complete the circuit.
This same process is to also be applied for your remote and 9V D battery. After attaching the battery snap connector, your black and red wires will be twisted with the remote's black and red wires, but DO NOT connect black with red for this pair!
Part 2: Tires
Now that the more challenging tasks are complete, it's time to install the tires on your vehicle. If you are using the metal pipes provided in the gear kit, you will find compatible tires included for secure attachment. These tires are ideally suited for the rear of the remote control car; simply align them and push to attach.
If the provided tires do not fit your car's axles, consider purchasing alternative tires from platforms like Amazon for a better fit. If you desire larger tires, please follow this link to explore suitable options. Alternatively, you can save costs by creating your own tires through 3D printing or by engineering them yourself; the link to the 3D printed designs for this project is available in the materials section of this page.
