Lawdawg,
Welcome to RCU!! There isn't anything wrong with your plane at all. That is the same plane that I learned to fly on 10 years ago. I still have it today and it's still flying great (600+ flights). Before you try to glue down the covering use a little heat instead. This plane comes with a heat shrink covering on it. Since you probably don't have a covering iron yet, use a clothes iron. Set it at about medium heat and apply it to the covering that is coming up. If it doesn't stick it down then turn up the heat and try again. Keep this up until you find the heat setting that is right. Using glue or other items for holding down covering should only be done if everything else fails.

Hope this helps

Ken
