Ask Tony

From RC Driver Issue: 134

You got questions, I have answers. Feel free to ask any RC related questions; questions on tuning, on article cars, on racing or just to ask how I’m doing! I’ll do my best to answer all of them.


coolingHi Tony. Love the magazine, especially the Ask Tony part. It’s been helping me learn more about RC all the time. I do have a question, though. If I put a heatsink on a brushed motor will that make it faster?

Hey Glen, The short answer is no, adding a heatsink to a brushed motor won’t make it faster. However, adding the heatsink will keep the motor cooler which, in turn, will help it maintain its maximum power for a longer period of time. You may perceive this as more power, but it’s actually not. If you have one I would suggest running it on a brushed motor as it will also extend the life of the magnets and brushes as well. Good luck!

Thanks for contacting me!

Got A Question?

Head over to the Ask Tony page and shoot me a message. I’ll either get it on the web or, if I like you enough, put it in the mag!
