I don't have the MT verision but I do have the Truggy edition, we have experienced just what you are talking about. We have tried the CC fan just as you have and still got the same results. I have read that some people replace the motor with a lower KV to reduce temps and also I have been told since the can has no cooling fins built in that a cooling setup that will attach to the motor and increase the motors cooling surface area and add fins would be better. I have not looked in awhile but will tomorrow when I go to Hobbytown and let you know if I find anything.
