I have to hand it to you Matt. You sure have done your homework on this model.

You asked many good questions and took your time. One thing I thought about when reading your post update on the project. With all the modifications you have made, make sure you check CG before your maiden. I would hate for you to miss this critical point and end up losing her on the first flight over this one. Also, make sure the darn elevators are not set too aggressively. As you have read on multiple post, she will snap if you get too much elevator throw.
I was going to fly this morning, but this cold front brought in wind and cold air. Hasn't been good flying weather over Thanksgiving. Good luck on the maiden and please let me know how it goes.
