Glitching makes Stampede undriveable

Ok, how do I isolate and eliminate glitching? First, batteries are getting too hot, I solve that problem then the controller is too hot so it's thermalling on me. I added a cooling fan and now it's glitching so bad and eraticly I can't control it. Is it possible it's the radio and not the motor and ESC? I'm using the Airtronics MX-3S radio and the Synth receiver it comes with. I'm about ready to toss the motor and controller in the trash and go back to a brushed motor if this keeps up.:o :o :o
