The balsa sheets already have the pieces pre-cut, right?
Have to agree with everything that's been written above.
I WILL say that balsa sheets in any kit I've ever built come as just that, balsa sheets. (Usually 3 or 4 inches wide, by 36 or 48 inches long. You have to edge glue them, then cut them to fit. They don't do the work for you.
And I've never met anyone who tried to transport an 11 foot wing in one piece.
