new in the world of electrics, just a few e-revo questions

Well all im gonna be doing is bashing, and maybe a few friendly races with my friends. So 40-45mph and long run times thats all im looking for. and on a budget so not too expensive..... So any setup sugestions?????

Well, given a lower budget, an 8 - 9xl motor running 4s 500mah lipos thru the Mamba max es shouldd get you about 30mins, f you keep your gearing at or slightly under 40mph. This would be driving at different speed while bashing, not wide open run up and down the street.
