OK guys, I need some help. I went out to the track today. My setup was a 9XL with the Mamba Max on 4S lipo geared 16/46 with the stock Losi truggy tires. After 30 minutes of running, the esc was at 115*F and the motor was at 190*F.

I just don't know what's up. I don't think I'm undergeared. Any body have any advise? Maybe I should go back to the 8XL, because the 16T pinion is the largest that I have.
