The depending on how your car is geared. My M-05Pro doesn't get all that hot outside of the motor. The esc gets to about 90* at most from all the corner exit acceleration, batteries if there LiPo do not get hot at all. Maybe room temp at most. If your using NiMH batteries they can get up to 140* but still shouldn't melt the latex/rubber combination of a balloon.
