Doing the gear calculator and estimating speed I know it's not 100% spot on but it's close.
I have been running 2s 14/54 with relatively no problems, a little cogging, at part throttle. 165*~ f temps at the end if a pack.
According to the calculator, 3s 9/54 is about the same speed. Which way should the heat go? Should motor be cooler? Smaller pinion? Or with the higher voltage warmer?
Sorry I don't know.
Looking at getting another battery, possibly trying 3s, and would like to prolong the life of my vxl.
Thanks in advance, merry Christmas.
