im just wondering if i can use my 8.4 / 5000 7 cell on my sprint 2 sport? And im thinking to get a new motor but i dnt know what kind of motor im getting yet? maybe some motor that i can use my stock esc

What is the input voltage of the speed control?

not sure about the batt, but stock esc has 21t limit

MATT i have the stock esc but how can i check the input voltage

FALLACI what do you mean by limit? is that no less than 21T?

if you're changing motor don't buy one with less than 21 turn (for your stock esc)

thanks fallaci ! well i put my old 12t titan and my xl5 esc its sounds fast but havent tried it yet, what do u guys think ,u think it will get to hot for thr stock gear from my sprint sport?
