Never say never. If it can happen, it will happen. My D300 was 60 flights old when I bought it. It had a rough early life, and not much easier since then. It has sat for the past 2.5 years in my basement with no attention to it, after I finished recovering it. One thing happened to my D300, while I was flying it, the right wing was ready to leave the wing tube. Not real sure why, but I drilled into the wing around the tube phenolic and poured in some GG. Laid wax paper over the repaired area, and set it in some wing shucks that were sent with the airplane. Laid the covering back down on it, and couldn't tell it when flying, but you could see the affected area when on the ground.
This was one of the best flying airplanes I have flown in all the years I've been flying GS. It is slowly becoming the "not my style" airframe. I need to get a paint job on it, and send'er down the road to the next guy. My MX2 and my 35% aircraft are more my style. I'm not saying that the Dalton isn't a great airframe, as it really is! It is super solid, well designed, and it flies great!
