Lex, have you tried that motor in another 4wd buggy with similar FDR? Because it could be your motor (even if in the past it was OK). Or try your current setup with a different (similar) motor? I think it's worth a try to see if you hit similar temps. Obviously, with the motor removed, do you feel any binding in the drivetrain? That needs to be checked...I'm currently running a Mamba max 5700kv system (from what I know roughly equivalent to a 6.5T-7T sensored motor) and geared 84T/22T and my temps are coming off at 170ºF in the summer heat here (yes, there is heat in Canada...), Although I do have a heatsink and fan setup on both motor and ESC...In all honnesty, I find your temps way high for a 7.5T with that gearing... Although the LRP motors are known to run hot...Hope you find the problem!
