Sorry to hear of your problems. I too had problems with a DP model, not the same one but the 330L. I had a warped wing, and that same wing was somewhat thinner than the other one. Also the stab tubes were not aligned properly. I ended up just working through it, and fixing the problems. Now I have what looks to be a pretty rock solid, and very straight and true airplane. From what I hear, DP service is not that great you may as well try to fix the problems. When I called them about the wing warp, I had already started in on the problem, got frustrated and emailed them. After two weeks, and already fixing the wing problem, I received an email back. The response was to send my wing in for inspection if I have not already started on it, and if determined a problem, they would discount a new wing panel! Wow what service! I obviously wanted to displasure of fixing there problem, or I would have called them on it. All in all, it is a very nice airplane, and if you have any experience with building, you should be able to work through it. Good luck with your project! Overall DP models are very nicely done! Oh yeah, I have yet to own a "Perfect" arf! They do not exist, and I do not expect them to exist! It sure is nice though to open that huge box with a pretty already built and covered airplane! Isn't it? Even if you end up recovering half of it later due to all the mods that it needed ha! ha!
