Losi 2.0 Conversion

That is certainly odd. I had lower temps going from a 12 tooth to a 14 tooth, and also from 12 to an 11 tooth. It's hard to do different runs without changing variables (5s vs. 4s, running area), but this seemed to be the trend.

Did you go back to using a 13 or 15 tooth after using the 14 tooth? One loose connection from the motor to the esc can increase motor temps A LOT. So can bad gear mesh.

Yeah I agree if 13T runs cool and 15T is ok, why would 14T cause temps to go high. I am thinking your on the right track on the gear mesh. The only thing that was different was the pinion and gear mesh. The buggy, spur and batteries were the same. What has me stumped is I tried the test two different times and had similar results (14T caused higher temps), I find it hard to believe I messed up the gear mesh twice and only when I tried the 14T pinion. Well, I plan on running the test a few more times.

13/45T - motor=128 degrees, battery=88 degrees
15/45T - motor=142 degrees, battery=98 degrees
14/45T - motor=176 degrees, battery=103 degrees

Or you can just say "screw it" and run the 15t

You know that's what I was thinking. The 15T feels pretty good, faster than the 13 or 14T setup. I am just concerned that the temps (142) well pretty good, would be too high when summer gets here. I like the temps the 13T pinion was giving me but I like the speed the 15T was giving me. I figured 14T would be in the middle and be perfect, but for some reason I am seeing the highest temps with a 14T setup.
