Thanks! I really hope to be good build. Really appreciate rare birds, some of them are almost unknown, even though may have great flying capabilities. I have serious amount of this type birds on my wish list. Here is templates for laminating wingtips and stabilizers. Now we just have to wait for other parts to arrive so the fun can start!

Here is parts removed from the sheets, and some dry fit before actual building begin. It seems that all is well, everything fit perfectly so far. No glue have been involved yet.
