my experience on the ucd3d is a little bit diferent. The facts are that in my part of the world, only 3 UCD3D have been imported. All of them arrived with a crushed wing. When the importer saw that, he decided to not import the plane in europe due to poor packaging of those big box.
After plenty of phone calls with the main importer, It has been decided that I will received the only UCD3D in europe (the one of the 3 with the less damages) for half of the normal price.

I have the plane and no visible damage, but when you shake the wings you can hear that there is some loosy parts inside.

I will remove the covering on the entire bottom of the wing for repair (bottom is the easiest scheme to redo).
I am really curious to see what I will discover undzr the covering, and I will post pic. Remove and reglu the firewall will also be a part of my assembly process
