Hi All,
I can't quite sort out my heat issues, so I'm going to start over from scratch. I thought I'd come get some advice from the experts.
Problem:
My set-up is running way too hot, and I can't figure out why. Within 5 min, the motor is too hot to touch, and if I run a whole pack, both the motor and the battery will be extremely hot (you can hold the battery, but it is much hotter than it ought to be). This is all happening on open grassy fields with short cut grass (short enough that 1/10th scale trucks run fine).
Set-up:
Pretty new EB48 2.0, built per the manual except for 100k fluid in the center diff. Currently running a Tekin Gen3 ESC, a 1700kv TPPower 4050 motor (measuring 40mm x 80 mm), and a 6s LiHV 3300 mah. I am running a 17t pinion right now, but was having the heat issues with a 15t pinion as well. I selected these components based on what some other members had run for their high-power, high-voltage set-ups, but something is working right for me. Ambient temps in NorCal where I live are pretty high, about 80-90, but again, I was having these problems earlier in the year when temps were 10-20 cooler as well (obviously the problem is even more severe now). I am running proline badlands MX (which are a bit larger and heavier than regular buggy tires, but definitely not 'very large' by overall 8th scale standards.
I am running a desert buggy cage with no panels, so there is tons of air flow over all the components.
Goal:
I'd love to be able to run a whole battery pack without cooking anything (motor or battery - the ESC seems to be handling all of this so far).
I am willing to buy a new motor and lipo as needed, and I am also willing to give up some top speed / performance in order to just run reliably and run cool.
So, with that background, I'd be grateful for some recommendations that would run cool.
Thanks!!
