Out of all that the thing that stands out the most is "You woun't be slapping the nitros around with the HV" and that means...i dont want it, i want something thats fast enough to beat nitro's, but when i want i can just go run it around bashing ...so my questions is...if i add more batteries,will the runtime increase as well as the speed?...cuz im thinking of getting the Feigao 540c 9XL motor+Warrior 9920 Car Controller (if thats a good setup) cuz itsa about the same price as the HV
