In this article, we will go over what a heat sink is and how it can be used in RC cars. A heat sink is an object that absorbs the extra heat from the motor of your RC car to protect them from overheating. Heat sinks are generally metal (aluminium) sheets with fins on them to increase surface area for better air circulation. Heat sinks are very important because they prevent damage to other components like bearings or brushes, which can lead to more expensive repairs!

What is a RC car motor heatsink
A heatsink is a cooling device usually made of metal that is designed to absorb the heat from an electrical or mechanical system. Heat sinks are attached externally and can be used on engines, electric motors, electronics, and even computers!
A heatsink typically consists of multiple fins with air-spaces between them in order to cool your motor to stop overheating and prevent damage to other components.
If you are building an RC car, heatsinks are a must-have for the motor and batteries! The fins on a heat sink will absorb the extra heat from your motor and prevent damage to other components like gears or bearings.
How does a Heatsink work
A heat sink will absorb the extra heat from your motor and prevent damage to other components. The fins on a heat sink increase surface area for better air circulation, which is especially important in an RC car that has limited space available such as cars with small wheels or low ground clearance.
Why do you need a heatsink
As we have already said, you need a heatsink if you are racing an RC car.
But why? If your motor is making excessive heat, the gears and bearings can be warped by this excess heat. This will destroy them in time!
Heat sinks prevent this from happening: they absorb the extra heat generated by your motors so that it doesn’t exceed its limits.
The best thing about these coolers is that they’re easy to find and cost-effective too! And what’s even better is that there are many different types of heatsinks available depending on your needs–making sure you get one perfect for your project!
A good example would be aluminium fins with copper base which provide great cooling efficiency at low weight
or thin aluminum plates with air space fins for better heat dissipation.
The parts are usually made from aluminium, copper or steel but there also exist some that use other materials like brass to improve the cooling performance of heatsinks!
Hobbypower Alloy Heatsink
This sleek heatsink from Hobbypower is designed for use with 540 and 3650 motors, but any motor using the 540 size can also make use of this sophisticated cooling technology. One side effects of such large machines heating up could be in damage to your wire insulation. Thankfully this clever piece of kit comes with a 5V cooling fan, which plugs into the receiver plug slot- so you don’t need to run extra wires or find ground spots for it! all for under $10.

Who doesn’t want to keep their motor running more efficiently and very cheaply? And, while this heat sink is made of high-quality aluminum and works on 540 and 550 size electric motors, it’s also compatible with most Traxxas, HPI, Tamiya, and Losi electric motors. All for under $10 Isn’t that awesome?
Conclusion paragraph: RC car motors use a lot of power and generate heat. A motor heatsink is an important part to keep your motor running smoothly for years to come.
It’s also worth noting that you may need more than one if you want the best performance from your vehicle. Find out what other parts are needed by checking our blog post on how to make your RC car faster.
