I have an E-maxx and am installing a 1515/2.5d with the 72 spur and need suggestion for what pinion. I used the speed calc. but dont know my diff ratio. What size heatsink for the 2.5d. I don't understand the "L", "XL" portion of my motor. Thanks ahead of time for your help. Everyone on this site has been awesome!!
