Hi, Paul
Nice job!
I felt the same when I received my E3d!

The 1/16 in balsa sides wouldn't have been so fragile, if it wasn't for the lighting holes behind the wing saddle.
After glueing the formers and the cruth to the right side, I lift the side off the building board and the fuse snaped in two. Right behind the former aft of the wing saddle. Really sucked!!
But after it was built, it seems pretty strong.
There has been a lot of problems with the landing gears popping off. Also the fuses have been braking aft of the wing.
In the GaryW QA forum there is a lot of people talking about the problems they have incountered.
