Sorry, didn't notice you put the motor your using in the text. lol!
I have that same brand motor in my eJato, the 3660 3300kv, but I just run it off the traxxas vxl-3s esc on 3S. I haven't run it a lot yet. Was looking at the 3670 for my stampede 4x4 if the HW 3660SL/3200kv gets too hot on 3S. It's running off the HW Max10SCT which has a temp plug for the motor, so won't be using that if I switch to the 3670.
