Hey everyone brand new to the forums and the MERV, so gf brought me a brand new MERV and I love it. Haven't been in the RC car hobby in over 10 years and I love this truck. My engine temps are about 130-140 using the 2C lipo, and 160-170 F when running the 3C LiPo. Are these normal temps?? Im running a 20T pinion, and the ambient temperature in Atlanta is about low 80's? Can you guys chime in please.
Please note that I was running Proline Titus wheels with dirt hawgs but switched to HPI 5 spoke 2.2's and Speed Hawgs since I mostly run on road and a bit of dirt driving. I just want to make sure the temps aren't gonna cook the ESC or Motor.
I was into pan cars a few years back and don't remember the temps being this high also LiPos didnt exist back then I mostly ran NiMh and yes I have a IR temp gun to guage the temps I always do after every 5 mins. TO ensure I don't break the 170 degree barrier. As Ive read that at 200 degrees F your killing magnets on the brushless motor.
Thanks again for any feedback.
PS this lil monster is insane compared to my old pan cars I used to run. Especially after installing the HR racing sway bars, and installing wider street tires. Its a MONSTER!!!!
The perfect motor temp is different for everyone... but my personal goal is anything below 180°F.
Especially in the Atlanta heat.
Now the question is what is your ESC running at??
Whatever it is I just typed... could be wrong.
I would keep a good eye on temps I had a motor go bad at 190
a traxxas heat sink on the motor will help a bit! and a fan on your esc
Jimmie the ESC was way below the motor. I have the Heat sink from Traxxas and when taking the temps on the motor I take it from the motor heat sinks and the back of the motor where the cables hang (the endbell I think) and the temps are about 10-15 degrees cooler that the heat sink. The heat sink is never hotter than the motor so far.
50togo what Fan heat sink do u recommend?
Thanks again to all who contributed.
Muchmore racing ultra high speed fan flows some good air. Probably a 25x25mm
Can u provide a link please, thanks. I want her to run cool as possible.
On ebay also
50togo how did u mount that fan on ur motor and esc?
Also ran her again today and installed a 18 tooth pinion and after 7 mins the motor was at 152 f with the 3c lipo and the esc was about 134 to 136 is this normal?
a 2.5mm bolt through the fan will thread right between the fins! 3 cell is really only for a few runs then let it cool.with running 18/50 gearing on a 3 cell you will go faster with a 2 cell and stock gearing 28/50!and run cooler
