Hey guys, I got a question about my top wing trainer which still has rubber bands that hold the wing down. After several flights I can tell the top LE balsa sheeting where the rubber bands go across the top isn't going to last much longer. I tried to repair one small crack awhile back but I don't think there's any support under there like on the trailing edge. What's the best way to do this repair/reinforcement so I don't add a lot of extra weight?
