Ahh right :), need to fix my cheap nitro car.
4S! christ haha i dont want to kill myself.
my blitz should do 55+mph with a 3s but will run the motor and esc hot.
I just ordered a 5300 mah 2s 30c lipo so i should be able to get about 35+ which should be plenty
not sure for the blitz as my hpi is nitro, I would lend you some 4c lipo's from my traxxas but they have the wrong connectors for the HPI , sorry
