Malachite Posted September 13, 2021 Share Posted September 13, 2021 Just popped a 3650 - 3900Kv brushless motor into my Zorro but the factory fit heatsink from the brushed motor is fractionally too big..... Do I need a heatsink with a brushless motor? Quote Link to comment Share on other sites More sharing options...
Ross9999992 Posted September 13, 2021 Share Posted September 13, 2021 You shouldn’t “need” a heatsink with any rc motors imo. If your motor gets too hot there are other things going on (gearing, esc settings, driver control issues, drivetrain problems etc. etc.) 👍🏻 1 Quote Link to comment Share on other sites More sharing options...
Tug Posted September 13, 2021 Share Posted September 13, 2021 If you can fry an egg on it, it's too hot. 1 Quote Link to comment Share on other sites More sharing options...
Gampla Posted September 13, 2021 Share Posted September 13, 2021 I would say that's up to you like others said not necessarily Quote Link to comment Share on other sites More sharing options...
Ag100 Posted September 13, 2021 Share Posted September 13, 2021 usually with these Heatsinks, they can be bent, I did it on mine just to make it a better fit, just squeeze the two halves together where the gap is if that makes sense, just don't do it too hard as it may snap Quote Link to comment Share on other sites More sharing options...
