I want to upgrade it to brushless to get a little more efficiency and speed out of it, the motor‘s capacitor recently popped with a ton of smoke, it still works tho. I found some cheap Surpass Hobby combos, they are in the 3300kv - 5900kv range and the can size is 380 in a 540 outer cover. So, would the diff and other gears handle one on 2s?
