Connecting Gears
Connecting gears in your remote control vehicle is crucial for ensuring smooth power transmission and allowing the design to navigate effectively and respond to user commands.
About This Section
Now that you have gathered your materials, constructed your chassis, and developed an outline for your vehicle, it's time to commence building your infrastructure. While this phase can be one of the more challenging aspects of the construction process, it is also the most rewarding, as this system will enable your car to move effectively.
How To Begin
At this stage of the car assembly, three essential sections require your attention. First, focus on the placement and installation of the front and rear axles without the tires. Second, ensure the accurate positioning of the gearwheels and their rotation at the front for steering. Lastly, consider the arrangement of gears and pulleys at the rear for optimal driving performance.
The Big 3

Car Axels
System 2:
Front Gears
System 3:
Back Gears
To start, create two circular slot holders to accommodate a long, thin metal or wooden pipe measuring 8-10 inches, positioning them at the back of the car's chassis. Ensure the holes are sized appropriately—large enough to allow for rotation, yet small enough to prevent excessive movement. Additionally, verify that the axles are compatible with your desired tire size. Note: If the kit doesn't carry a long enough axle size, it's possible to connect two smaller ones together using the soft 1 cm orange spur from your gear kit.
Next, install the front axles by drilling two holes on the front sides of the chassis, placing rounded cylinders on top and inserting the pipes vertically. Raise the chassis and bend the pipes into a zigzag formation to facilitate steering.
If utilizing the kit’s pipes for the front, you may need to use a lighter to soften the sides while employing pliers to achieve the correct bend; this step may not be necessary for alternative materials such as paper clips or flexible metals. However, note that wood is not suitable for the front axles due to its lack of flexibility.
Begin by installing a front holder 1-2 cm in front of a steering stand, drilling holes in both to accommodate a smaller 1-2 inch metal pipe positioned horizontally. This pipe does not need to rotate, but ensure there is sufficient clearance for easy assembly and disassembly if removal is necessary.
Now, from your gear kit, start by using pliers to insert the pipe and attach a 1 cm double-stage spur gear between the steering motor and front holder. Below this, position a long rectangular rack to the front axles.
Finally, at the top, a small 0.5 cm spur gear at the end of motor to unify all three components and facilitate steering. Please note that depending on your chassis, you may require gears of varying sizes and/or placeholders to accomplish this.
Positioning the driving motor either flat or sideways, secure the motor using screws or tape for stability, and then attach a 1 cm helical gear to the edge of the motor. The following steps may vary based on your specific car model.
If the rear axles are still in, remove them from the chassis, and create a small rectangular hole between the left and right holders to allow for the vertical insertion of a gear for the pulley system. Using pliers if necessary, insert a helical gear approximately 1 inch or larger through the axles and above the hole and attach a small rubber band around it. Connecting one end to this gear and the other to the motor's gear, additional placeholders may be added as needed to ensure a smooth rotation.
