Where abroad will you be traveling to? When I was traveling around Asia a few months ago, I actually carried a copy of the drone laws for each country with me in the native language and English. Glad to say I never had a problem.
Also you might want to bring your receipt with you so that you can prove you brought it with you and avoid any customs hassles when you return.
Quick question, when you fly somewhere, do you jump out or wait for the plane to land?
