When I travel/fly I take a duffle bag with me just in case I find some ( 1/18 size plane) like item at the local WM so that I can carry the duffle bag with me on the plane and check my luggage. I have done this twice and got a RidgeRunner and Corsair back.I'll be going down to the LA metro area next week on a business trip. Will use the evenings to scout around for the Avenger.
With the Avenger being such a large box/plane I dont know if it will fit within the carry-on rulings for airlines.
