Right now I have my 7XL running on 18 cells with a 12 tooth pinion. I'm running 40 Series Moabs and an MBX transmission with a 51t spur gear. I'm a bit overgeared I think with this current setup, when I switch over to my 10XL should I change the gearing a bit? I was thinking that since the 10XL doesn't run as hot it will be less overgeared.. Any suggestions appreciated.
