Question about ESC effect on motor temp

Hey guys. I have a flying wing and I was trying to get a fast setup on it with a 3648 1450kv turnigy on 4s and a 9x6 prop.

It pulls over 100 amps for sure. I was using a hobbywing 100-120amp ESC and its not cutting it. Sometimes it works but frequently cuts out when it gets too hot.

I totally friend and smoked one of these motors with a 10x7 prop LOL the motor burnt to a crisp but the ESC was ok? go figure?

so aiming for the 9x6. Even with the 9x6 the motor gets VERY hot. Not hot enough to burn on touch but close hot enough so you can only tap it really quick with your finger. The ESC was hot also. It was a 90 degree day also all things considered.

I don't want to run a motor too hot for obvious reasons (ie don't want it to go bad when not expected)

My question is if I get a better ESC that can handle 200amp would this cause the motor to run cooler?

Also I'm using turnigy nanotech 65-130C batts If I use say 30C batteries instead of 65c batteries will this
decrease the motor temp also as well?

Thanks for your help!!
