Am pretty close to having mine built. Am using a YS .63. The hinge slots in the wing and ailerons were both too shallow and off line , which required a little work. I was amazed that the stab and wing were square with one another without additional work. The fin was not aligned and took some sanding in the pocket to align and epoxy in straight. One thing a couple of people have mentioned already is the landing gear plate. I might beef mine up and add a third screw and blind nut to the gear. Don't have a clue how the carbon fiber tail braces will hold up , but they were easy to install.

All in all, pretty positive so far. Sure like having the motor mount blind nuts already installed!
