I know you need to discharge the flight batteries completely for airline travel and you need to bring them in carry on even if you p3 is checked luggage. Now that the transmitter has a lipo battery powering it I'm gonna have to bring the whole controller with me also? Something is going to get broken with the antennas not to mention having an oblong item in my backpack in addition to all the batteries i'm having to carry on also. Can the battery in the transmitter be removed easily? Seems like they should have thought about the travel headache of having to carry on the controller.
