Delta telephone customer service is killing me. I want to know if I should check or carry on my P3P (I have 3 batteries). After spelling the word "DRONE" and "QUADCOPTER" to them several times (they are in India) they finally got back and said its okay to check or carry on. I doubt it. I explained that they are 100watt Lipo's, etc. Am going to get to the airport and find out I need to leaving there!?
