RE: Showtime for Pattern flying?
Not suprising it doesn't snap using 3D rates and doing a Wall. Most of those reports of unexpected snapping sounded like they were using a lot of elevator, but not all of the 3D travel available, so they were getting it into a typical acceleratde stall without ever transitioning into "3D Barndoor mode". I would expect a snap in that case, especially if the airframe is overweight at 10 lbs. Go spend $7K on your favorite 40% whatever and it will do the same exact thing. Everything sounds quite normal actually.
I haven't flown mine yet, will hopefully have some weather for it this weekend.
