Many Post Offices now have self-service areas in the lobby where they have a super accurate, legal scale. In most cases, there is enough room around and above it to weigh your plane in one piece, or wing and fuselage separate.

It's free, and late at night, nobody is there to give you a funny look for bringing your plane to the post office! The self serve area near me is open 24 hrs.

Mark, I hope you enjoyed the photos of the UltraStick 60 I sent, courtesy of our friend, BJ.
