DBXL Smithy Posted May 9, 2016 Share Posted May 9, 2016 Hello all. I recently bought a brand new Traxxas Slash 4x4 and up to now I am loving it whole lot different with a 2s LiPo. Now about heating problems. My motor is reaching around 64.2c after a 20 minute run and my ESC is reaching around 31.1c after a 20 minute run also. Is this overheating? Also should I be checking the temperature of the LiPo battery every so often? Will this help keep the ESC cool? - http://www.modelsport.co.uk/index.php?product_id=29191&gclid=CjwKEAjw6sC5BRCogcaY_dKZ2nESJABsZihxyvrtkxbTKor7TeYJ5I47M6x9LaMpeMR6VkQndXGi1xoCC5Hw_wcB Can you buying anything to keep the motor cool as well or would I need to buy a heatsink motor? Thanks. Quote Link to comment Share on other sites More sharing options...
Alex97 Posted May 9, 2016 Share Posted May 9, 2016 64°c is a little high but not a massive issue. 31°c is fine for the ESC Quote Link to comment Share on other sites More sharing options...

Thanks. Points for keeping track of the temps But as noted there well within parameters, especially considering outside air temps at the moment. If it was mine I'd fit an ESC fan, if only for peace of mind and longevity, though you should be able to do it for a lot less than the £20 plus for the Traxxas one. I only run one motor fan, and that's on a plastic fantastic Maverick Strada clone, everything else I have has a metal motor mount bolted to a metal chassis which helps to transfer heat, and prefer to have airflow scoops (cheeseboard holes) on the basher shells for extended running in very hot weather.

Deafty Posted May 9, 2016 Share Posted May 9, 2016 as long as your readings are accurate 65 will be ok. For me a warning goes off in my head if I'm over 60. What u need to know is anything over 80 is where demagnetization occurs and severely reduces the motors life. If u are over 70 get concerned quickly Other motors will run cooler than what u have fyi Quote Link to comment Share on other sites More sharing options...
Oh How Original Posted May 9, 2016 Share Posted May 9, 2016 Heat sinks can just slide over the motor if you're really bothered bud. I used to like to keep mine below about 55C but it's not always easy without losing a bit of speed. Quote Link to comment Share on other sites More sharing options...
RCbutcher Posted May 9, 2016 Share Posted May 9, 2016 I think a good motor heatsink will be just as good as a motor fan. Use thermal paste too which I'm told makes the heatsink much more effective. The vxl is a crappy system for heat issues tho but I usually only hear of heat problems with 3s lipo. Are you using the Std gearing? When you replace the vxl the hobbywing sc8 esc is a beast for the slash using 2s or 3s will give it an easy life and hopfully extend its overall life. Hobbywing or Leppard motor it'll be sweet. Turnigy trackstar 2650kv is popular in the slash too but 2s might be pointless. Quote Link to comment Share on other sites More sharing options...
DBXL Smithy Posted May 9, 2016 Author Share Posted May 9, 2016 (edited) I'll try out these. Aluminium 1:8 Size Motor Heatsink With Fan - http://www.wheelspinmodels.co.uk/i/72270/ Been told it will fit Traxxas Slash 4x4 stock motor.
