Sorry if I am beating a dead horse, but...
Who on here knows the main difference in choosing spur gear. For the Xmaxx, you can use 46, 50, or 54. My brain tells me that if you go from a 50 to a 46 it will have more torque with more speed, but they call the 46t spur the "speed" gear. Someone please help me wrap my head around this!!!
 
Ok smaller spur means less tourqe and more speed, I find that a good 18-20/50 is good in the xmaxx for general bashing đź‘Ť. They only recommend the 46 for speed runs because the smaller the spur (or bigger the pinion) it takes more for the motor to push it, this causes overheating.
 
Thank you. I will head down to the hobby shop and pick up a 50t spur to try out. I'm looking for just a slightly higher high speed than stock 18/54 without causing heat issues or lighting my ESC on fire.
