Just got in a 4* 40 from a member here Friday.
I completed air frame Sunday. ( Kit built very easy and straight )

The question or concern is, the wing. It seems weak, it will flex very very easily, not up and down but front to back.

I was wanting some ideas on how to maybe make it stronger before I cover it.
The way it is now, I think I'd break it on a hard snap roll.

Thought about completely covering the wing with balsa sheeting.

Thoughts, ideas?
