Well, sometimes it seems that people learning can put their airplane in some really high g maneuvers. We'll call it beginner aerobatics. While todays ARF's seem to be really nice, the little sticks that come with the trainers to join the wings are NOT suffecient for the task.

A really easy method for applying fiberglass tape is to use a glue stick to attach the tape to the wing. Start on the top at the trailing edge and work your way forward and over, returning to the trailing edge on the bottom. Use just a small amount of glue. All you want to do is tack the cloth in place.

Once you have that complete, mix a batch of 30 minute epoxy. About 1/2oz or so. You don't want to run out while you're working. Apply the epoxy carefully with a card. It doesn't matter what brand, as long as it's stiff. Work from the inside out and from front to back. If you've applied too much pressure, just trim it at the trailing edge.
