if you change your mind about going to brushless, i had a e savage that i kept with the stock esc ran 2 venom 5000 mah lipos converted to deans of course a novak cutoff switch and kershaw battery trays and it hauled ass i mean a major speed change, you could also get a traxxas evx 2 esc with a built in lipo cut off as well. If you are hell bent on going brushless i believe trakstar has good conversions for it as well good luck.
