I have seen a Dutch driver where beside the charger cable and balance cable another cable was going into his LiPo bag. He was using a single tire heater on a cheap GTpower electronics set to the max legal 10 degrees above the ambient temperature while the rules say no external heating allowed.
You may say it is no cheating when not caught, to my knowledge cheating is not acting within the limits of the rules with or w/o being caught..
