Well, I used to... I am still very appreciative of the demand for such aerobatics and enjoy watching them, but after seeing it you get used to it. For example, when Quique, essentially, introduced high alpha flying at, I believe, the '99 or '00 TOC, he started with the Elevator. The plane appeared to be just dropping straight down while maintaining a horizontal attitude and people FREAKED OUT!!! He then went into some harrier variations and into a torque roll and people LOST IT!!!! He continued torque rolling and brought the tail down to within, like 2 FEET of touching the ground and the crowd ROARED!!!!!
Well, now, 5 years later everybody and their sister is doing that stuff and people don't even turn their heads anymore, it seems. From an entertainment standpoint, watching 3D has lost its luster, IMO. But doing it is still just as exciting. I just don't see where else this hobby can go, except pitch changing props on giant scale aerobatics, maybe[X(]
