[its me]

I am sorry for asking and have tried to use the speed estimator with no luck...my question is what size/tooth count of pinion do I need?
truck has....

45T/11T diffs

48T Center diff

Motors will be duel running feigao 7XL

Power im planning to use is 4S for each motor and if I can get away with it then 5S?!?!?!

I spent awhile typing in info for the speed calculator but no matter what I did I kept getting17-20MPH, I am thinking gearing for 60MPH is a good starting point for now.

Thanks for the help, this money in PayPal is dieing to be spent :)
