First, welcome to the forum. I think your points are valid, properly delivered, and well taken. I was more fortunate with mine, it didn't have many of the problems you listed. We all got stronger tail wheel brackets and mine has not failed in many many landings...some not very light. The landing gear and wheels were a different story. Cracked that gear and peeled the paint in no time. The foam wheels should not go on any planes this heavy. I went with Graphtech CF gear ($25 clearance at Toledo, love that) and Dubro light flight tires and it's way better. I love it. As far as the plane's performance, unreal. I sold all my glow stuff after flying this plane. Nothing came close to this plane.

Edit: Came back to post this. Funny how the first bad experience can turn you off forever. Take the DA50 for example. Many people love theirs, but I had this annoying dead stick problem at idle while inverted (others have too). After a summer of flying and too many close calls, I threw in the towel (after DA said there was no problem when I sent it to them). I sold the DA 50 and bought (2) ZDZ 50's. Take JohnVH for example, has one in his BME Edge and does not have the problems I did. It's an older engine. Well anyway I will never buy another DA 50 again. That's my personal decision and all it took was one bad engine to do it. Even if it's possible if I were to buy ten more and they all turned out perfect. I won't buy another. ***** happens.
