Is it this shredder?

That lists a 120A esc, but looking at tower and others, it does show it with an 80A. Just seems odd to have such a small esc in a 1/6 scale truck. In theory, the max10 sct can handle 120A. I can't for the life of me find what size the 1300kv motor in it is. The max10 sct is intended for 36mm motors. I run one in my stampede with a hobbystar 3665 3100kv motor and it does ok on 3S. Guessing if I wanted to try 4S, I should get s 2400kv or less motor.
Odds are, you'd be better off with a max8 in that size of truck.
