I too hit that "90%" mark and stall out sometimes. I keep plugging away and before you know it that revelation comes, "I FINISHED"!!!!! You can set back and enjoy what you have accomplished. Then the really fun part, the maiden flight. Now, that is when the real satisfaction sets in.

Don't give up. Don't kill yourself thinking you have to get it done tomorrow. Take your time and it WILL happen.

It's looking really good so far!!
