Thanks for all the help man. I still need some help though....<div>   So, let me see if i have this right. If I run say 32" Cat, I should run 4S LiPo around 3700 maH with 55c. That would put me in the range around 1800 Kv for my motor and around 120A for my ESC. Is this right? What would my RPM's be? what would the speed / run time be like?</div><div>  Also, would it be best to use 1 battery or 2? If 2, how do i parallel connect them? </div>
