120 continuous is what that rating probably is....which is plenty. I never see the amps get near that driving around. Under acceleration...they get up pretty high. The Castle Mamba Max X is just smoother than the stock ESC. It feels more connected and you can fine tune a 6S pack to be much smoother also. Just set a throttle curve up on a graph and adjust it to where it runs smooth. Problem with electric motors is they just want to go 100% asap. This hobby is radio control....the more ability you have to control stuff...the less you bust and stress out. You fine tune a 6S through a ESC with lots of features....You got yourself a vehicle that runs great on any battery. I can run 3S to 6S and make it all happen without blowing tires, puffing packs, exploding diffs etc.
The op is using a Tekin ESC....great choice. There is no comparison between a roller Kraton built with quality electronics and a bone stock one. There is no way they will feel the same.
