If you're gonna build a wood 2 meter plane, you MUST make a jig of some kind and be SURE it's straight. It doesn't take much of a bend or twist and that thing will never fly straight no matter what you do. Just get creative, take your time and think about it. But jig it up before you EVER come near it with glue.

That's just my little piece of advise, I hope you do this. It will make you MUCH more successful in building this thing straight.
