One innovative method gaining traction among hobbyists is the use of silicone earplugs to lock the center differential. This creative solution offers several advantages over traditional locking methods, making it an appealing option for RC enthusiasts looking to optimize their car’s performance. In this article, we’ll explore the benefits of using silicone earplugs to lock the center differential in an RC car and why it’s particularly ideal for preventing front wheel ballooning.
Advantages of Using Silicone Earplugs
Cost-Effectiveness of Silicone Earplugs
Silicone earplugs offer a budget-friendly alternative compared to other materials commonly used for locking differentials, such as epoxy or specialized locking compounds. This affordability allows hobbyists to experiment with different setups without breaking the bank.
Earplugs are Easily Sourced Locally
One strong advantage of using earplugs to lock our differentials is that we can easily source them locally. All you need to do is head over to your local drug store and you will be able to find a set of Silcone “Diff Locking Kits.” This is simply amazing as in every city there are going to be more drug stores than RC stores. Personally, my local store is 45 minutes away making this a huge win for me.
Ease of Application
One of the standout advantages of silicone earplugs is their ease of application. The process is straightforward: simply press the earplugs into the differential to fill the space, and they will conform to the shape, effectively locking it in place. This simplicity saves time and effort, allowing enthusiasts to focus more on fine-tuning other aspects of their RC car.
Reversibility
Unlike some permanent locking methods, silicone earplugs offer reversibility. If you need to revert to a differential setup for any reason, you can easily remove the earplugs. Using Silicone earplugs will not cause any permanent damage to the differential. This flexibility provides peace of mind for hobbyists who may want to experiment with different configurations in the future.
Preventing Front Wheel Ballooning / Excessive Front Wheel Power:
Front wheel ballooning happens when front wheels excessively spin and expand during acceleration. It negatively affects RC car handling and stability, particularly on high-traction surfaces. Locking the center differential with silicone earplugs helps distribute power evenly between front and rear wheels. This reduces the chance of front wheel ballooning.
Silicone earplugs, when effectively locking the center differential, prevent disproportionate power transfer to front wheels during acceleration. This maintains better traction and stability. It’s beneficial for RC cars with all-wheel-drive, where open center differentials cause excessive spinning of front wheels.
Applications where Locking the Center Differential is Common:
Locking the center differential finds common applications in various RC scenarios, particularly in on-road buggies equipped with a center diff. Without a locked center differential, achieving strong acceleration to reach higher top speeds becomes challenging, as power distribution across all wheels can lead to wheel spin and loss of traction. To ensure that RC enthusiasts efficiently transmit power to all wheels, they can implement a center diff lock using silicone earplugs. This results in smoother acceleration and improved speed performance on straightaways and corners alike. Moreover, in off-road vehicles where enthusiasts aim for spectacular stunts like wheelies, locking the center differential can bias more power to the rear wheels, enabling them to lift the front end and execute thrilling maneuvers. Furthermore, for operations on grass and dirt surfaces where traction can be limited, a locked center differential enhances rear wheel traction, providing better grip and control for navigating challenging terrains with ease.
Conclusion:
Using silicone earplugs to lock the center differential in an RC car offers a cost-effective, easy-to-implement solution with reversible benefits. Beyond these advantages, locking the center differential with silicone earplugs is particularly effective in preventing front wheel ballooning, thereby improving traction, stability, and overall performance. Whether you’re a seasoned RC enthusiast or just getting started, consider experimenting with silicone earplugs to unlock the full potential of your RC car where ever you plan to drive!

Are We Incorrectly using Kv for an RC Brushless Motor?
RC brushless motors are becoming increasingly popular in the hobbyist and professional markets due to their high efficiency and power output. One common term used to describe these motors is Kv, which stands for the voltage constant. Kv is a measure of the motor’s RPM per volt of input. While Kv is an important parameter for selecting and matching the motor to a particular application, there are some misconceptions and limitations surrounding its use.
The purpose of this article is to examine the use of Kv in RC brushless motors and its limitations, as well as provide alternative methods for selecting the appropriate motor for a specific application. By understanding the proper use of Kv and other motor parameters, hobbyists and professionals alike can optimize their motor performance and achieve their desired results.
Understanding Kv, the Velocity Constant
To understand the use of Kv in RC brushless motors, it is important to first define what it means. As mentioned above, Kv is the voltage constant. It is a measure of the motor’s RPM per applied volt. Essentially, it tells you how fast the motor will spin at a given voltage.
To estimate Kv, divide the no-load RPM of the motor by the input voltage. For example, if a motor spins at 10,000 RPM when supplied with 10 volts, its Kv would be 1000.
The Kv of a motor is affected by the number of turns, magnet size/shape, and stator/rotor design. High Kv = higher RPM per volt, low Kv = more torque per amp.
Note that Kv constitutes just one of several parameters to consider when selecting a motor for a specific application. Factors like maximum current, motor efficiency, and weight warrant consideration as well. Moreover, Kv alone fails to provide a comprehensive understanding of a motor’s performance and necessitates integration with other motor data for informed decision-making.
The limitations of Kv
While Kv is an important parameter for selecting and matching motors to a particular application, there are some misconceptions and limitations surrounding its use.
A limitation of Kv arises from its frequent misuse as the sole determinant for motor selection. In truth, relying solely on the Kv value does not furnish adequate information to ascertain a motor’s suitability for a particular application. Factors such as required power, torque, and speed must also be factored in for a comprehensive evaluation.
Another common misconception about Kv is that a higher Kv value always translates to better performance. In reality, selecting a motor with too high of a Kv value for a given application can result in a motor that is too fast and lacks the necessary torque per amp to perform the desired task. Note how we discuss torque as torque per amp, this is important.
In addition to these limitations and misconceptions, other factors can significantly affect motor performance. For example, motor efficiency, maximum current, and thermal characteristics can all have an impact on a motor’s overall performance. It is important to consider all of these factors when selecting a motor to ensure optimal performance for a particular application.
Overall, while Kv is a useful parameter for selecting RC brushless motors, it is important to understand its limitations and use it in conjunction with other motor data to make informed decisions. By carefully considering all relevant factors, hobbyists and professionals can optimize motor performance and achieve their desired results.
Alternatives to Kv
While Kv is a commonly used parameter for selecting RC brushless motors, there are alternative methods that can also be effective in choosing the right motor for a specific application.
One alternative is to consider other motor parameters in addition to Kv. These include maximum current, motor efficiency, weight, and thermal characteristics. By taking into account all of these factors, a motor can be selected that is optimized for the specific requirements of the application.
Another alternative is to use motor testing and data sheets to help in the selection process. Motor testing involves running a motor under specific conditions and measuring its performance, such as speed and torque. Data sheets provide technical specifications for the motor, including maximum motor RPM, maximum current, and maximum voltage. By comparing data from various motors, a hobbyist can make an informed decision about which motor is best suited for their application.
Finally, it is important to understand the specific requirements of the application when selecting a motor. Factors such as vehicle size, vehicle weight and desired speed can all impact the motor motor required.
Conclusion
While Kv serves as a useful metric in RC brushless motor selection, it should not be the sole factor considered. Kv denotes RPM per applied volt, approximated by dividing no-load RPM by input voltage.
Limitations associated with Kv encompass misuse, misconceptions, and other factors impacting performance. We highly recommend evaluating other motor parameters, utilizing data sheets, and comprehending application requirements.
For optimal performance, it is crucial to consider all pertinent factors when selecting a motor. A comprehensive approach to motor selection enables hobbyists to attain their desired results effectively.
