Has anyone taken their Phantom thru a TSA checkpoint? I'm not concerned about the drone( but who knows), but the batteries. When I returned the P2V the Post Office clerk almost refused it because it had a lithium battery in it. 'Fortunately there was a smarter clerk there. So I worry the TSA (not the sharpest pencils in the pocket) might say the batteries are illegal or some other stupidity. At that point there is nothing you could do but throw the battery in the garbage can(so the TSA guy can retrieve it and sell it on ebay). So has anyone gone thru with their Phantom in hand?
