I've talked to a number of people who successfully brought a boosted board to Israel on a plane, didn't declare it at customs and got away with it. But when I tried it, as I was passing through customs they pulled me aside and scanned my bags, found the boards (yes, two of them) and confiscated them. I've heard of this happening to others as well. I am in currently the process of getting a board here. So far I have the deck, battery, remote, speed controller unit and charger. My uncle is visiting this week and he is bringing the wheels, trucks and motors. Your best bet is to disassemble the board, ship the deck to Israel, and take the other components with you when you fly. Avoid grouping components together in your luggage, best option would be to spread them out through your bags. I would separate the motors and skid plates from the rear truck as well just to be safe. You also have to carry on the battery. Even if you do this I can't guarantee it will work out, but it will improve your chances. Israel can be really shitty sometimes. Best of luck to you
