I have a 10 gram lighter phantom ver1.1.1 and my batteries get quite jot during flight. I'm talking around the 45-50 degree centigrade temp(guessing). I will measure this when I buy an infra red thermometer. Just curious as tho wether this is typical or if I have something wrong with my aircraft. Happens with all my batteries. Original phantom battery, 2200Mah turnigy and 2700Mah Titan RC.
