How Do You Change the Gear Ratio on an RC Car?

Changing the gear ratio on an RC (remote controlled) car is a great way to improve its performance. It can give your car more speed, acceleration, and torque.

It also allows you to fine-tune your car for different terrain, as well as for different racing situations. Changing the gear ratio can be done relatively easily with a few basic tools.

The first step in changing your RC car’s gear ratio is to remove the pinion gear from the motor shaft. This can be done by using a pair of pliers or an adjustable wrench.

Once you have removed the pinion gear, unscrew the four screws holding the spur gear onto the motor shaft. After this is done, you will need to remove the spur gear and set it aside.

The next step is to purchase a new pinion gear that has a different number of teeth than your original one. The higher number of teeth on your new pinion gear will result in a higher top speed for your car while the lower number of teeth will result in higher acceleration and torque. When selecting your new pinion gear, it is important to make sure that it has an appropriate pitch for your motor.

Once you have selected and purchased your new pinion gear, reattach it to the motor shaft using either thread locker or Loctite glue.

Carefully align the two gears so that they mesh properly with each other and then reattach them using either thread locker or Loctite glue.

Finally, replace the spur gear onto its mounting screws and tighten them securely. Make sure that all of the screws are tight so that there are no loose parts that could potentially cause damage to other components in your RC car.

Conclusion: Changing the gear ratio on an RC car is not complicated but requires some basic tools and knowledge of what type of pinion gear you need for optimal performance. With some patience and attention to detail, you can easily adjust your RC car’s gearing to suit any situation or terrain!
