Default Cogging help

I got an unused crt.5 truggy with a mamba monster max pro and a tekin sc4x 4.5t. The motor worked well the first day but the next day had really bad cogging issues with the motor reaching high temps fairly quickly. I've also tried running to motor without the pinion and there was evidence of cogging.

The motor and esc had a bad connection that would disconnect after a few bumps on the road so I resoldered and cleaned the esc connections with no success on fixing the issue.
______________

Here is the part I need help on.

I do not have a sensor wire and cannot test the other setting. I also do not have a castle link to try to put more punch during startup.

I've read of an underpowered battery solving the issue but i tried a 3s 5000mah with no success.

My pinion gear is at 20 at spur gear at 46.

I've recalibrated the esc many times.

_______________

Is the motor or esc bad? Should I spend the extra $30 to buy a castle link and sensor cable to fix the problem? Is there any other suggestions on making it work?

Thanks in advance!

edit: I tried swapping the a and c wires to see if that would help... nope

k. thanks. When you say, "gear down," you mean have a smaller gear ratio, right? so smaller pinion and larger spur?

yup. usually being geared too high is the #1 cause for cogging.
