I run the 12t pinion in my kraton. After 2 packs my motor was too hot to touch. My question: does the esc shut down before the motor gets too hot or will it just burn out if I don't check my Temps??

I can’t even get a single 3S 5000mah pack to LVC on my Granite BLX before the ESC overheats. It’s not even 80F here yet. Thinking the pinion/spur mesh is off, as others have mentioned. I wasn’t even driving wide open or anything either. Just tuning in loose gravel and dirt. Couldn’t run all out or it would spin out. Not enough traction.
odd, with twin fans on our motor we can run 3s pack after pack and never have the ESC complain, it always stays cool
Link to fans you’re using please?

Im running both into one connector then into the reciever, thats only 6v, put my temps from 180 to 120f. massive change drop and it let us run multiple packs. use long screws deep down into the heatsink but also don't overtighten.
I had 3 ESCs and they all overheated. I think having the body so low isn’t giving enough airflow. Mesh is good, drivetrain doesn’t bind.
Don't sound like the reason to me.Turned out to be the receiver that was bad, it was requesting too much throttle (could not calibrate) and over amping the esc causing an error. Weird problem
Cool response but when my Max6 was flashing green it was at 85 degrees. Max6 escs aren’t sensored and don’t throw an overheat error when the motor gets hot. Strictly the esc.Don't sound like the reason to me.
If you never service your Motor, BB's cleaned out, relubed with a synthetic oil, etc. Stocker motor BB's suck. Are usually dry of any lube. The motors will get hot even if it is 40F ambient temps outside. How you drive matters as well. Proper Gearing being a given for how and where you drive. And weather's temps must be accommodated.
Every RC'er needs a temp gun to monitor all the electrics. They are a cheap tool and good insurance. A motor that runs any higher than 140F (externally checked at 3 places on the motor) is cause for alarm IMHO. Cool down periods are important as needed. Or risk a bricked Armature as well as demagnatizing the armature's magnets. Permanent damage.
Having adequate Fan(s) is always a given. No matter what. I dislike Heatsinks. And find that a Fan mount alone and high CFM fan(s) are always best over the years of testing them. The Motor IS a HS by design already. I'm usually running (2) 40mm x20mm fans (28 CFM's each) on my hot running motor setups.. You can never have too much cooling overhead.
My spin.
