and this ********* ESC on a 3s lipo
Cont. Current: 100A
Burst Current: 200A
Car Size: 1/10th

On/Off Switch: Yes
Thermal Overload Protection: Yes
Battery Terminals: 12AWG size
Motor Terminals: 12AWG size
Problem is that it's running pretyy hot with the stock gearing (19t pinion 90t spur). I went down 1 tooth on de pinion (18t) and it seems to get even hotter (could be me, don't have a temp gun).
I have now ordered a 16t pinion and a 92t spur which will hopefully make things better. But will it? I noticed that in some cases a larger pinion (let's say 20t) made the motor and esc cooler. I guess this would have to do with less rpm's? Then again it will also increase the load on the motor so I think I'm not understanding it fully.
I was running it (as a test) on the street and on some gravel but it should work offroad (there's a small track close to my house). After 10 minutes or so the thermal protection kicks in (which kind of s*cks as it also cuts power to the steering servo, not very nice when this happes while going pretty fast).
Anybody willing to shine a light on this? Am I turning into the wrong direction?
