There was this guy that used to fly a Goldberg Eaglet at our field. It was the ugliest plane I have ever seen. The stabilizer was on crooked. It had so many patches that it looked like a quilt. In fact, if it had been a car there would have been one white wall. It flew fine, though. You can get away with a lot on a model. If your planes has a few wrinkles that's ok. If you're unsure, have someone in your club check it out.
