RE: any advice before maiden flight?
Get on a buddy box with that instructor. That is one beautiful airplane. You will be dying to fly it. He can take it off, then you fly it around for awhile. When it's time to bring it in, if you are uncomfortable doing it, he can land it. At least you will have flown it on its maiden flight. I too would like to see a pic of it with the wing on. You did a fantastic job.
