Travelling with model aircraft and LiPo batteries

Some hints from Chris Anderson:

I carry the drones in a Pelican case, which is checked luggage
I enclose a note in the case explaining what they are, for the TSA to read. I use phrases like "robots for a competition" rather than use the word "drones".
I carry the LiPos in my carry-on luggage, in a bag that clearly marks them as batteries.

And a document with guidelines for travelling with batteries.
