erevo heat issues

[jediguru]

First off here is the setup. Erevo with 9XL, MM, 8000 True rc, 20/68 gearing. I cannot for the life of me get my temps down. Both the motor and esc heat up quickly within the first couple minutes to around 200 or just under. I originally had started with a higher gearing and was having problems so I have geared down to 20/68. Should be plenty low enough. I was having no problems running this setup before in a revo conversion with higher gearing17/36(mod 1). No heat issues what so ever with that setup. The only difference is motor brake as opposed to mechanical. I've checked the truck over for drivetrain drag, lowered the timing, disabled reverse. Don't know what else to try. Could the esc be bad? Any help would be much appreciated.
