MM settings?

[Rnemhrd]

I have a medusa 36-60-2000,mm w/bec, and novak cap running 8000 spc 15c. from a dead stop it coggs badly. Once rolling it is good. It is in a x1crt. gearing is 17/62. I think the gearing is off. esc settings are 0 timing. low start power, and 30% punch. Any ideas. Once rolling it is an animal. I'm thinking a 15t pinion. It came with the 17. I also have the ofna six gear spider center diff with a 52t spur on it. What do you guys think I need to do. I do not mean to treadjack but I did'nt want to start a new thread. Bustitup's setup was basicly the same. motor and esc wise. Thanks
