i recently biult my fitst wing, i have just the skeleton done (no servos, covering or ailerons) i am able to twist my wing a bit, is this going to be fixed when i cover my wing, or do i need to put in diagonal braces between wing ribs, i dont want to because it will ad a siginficant amount of weight to my plane.

also if any of you pro's out there have any good tips for covering a wing using monocote stuff please it will help...

thanks
