RickP and Snowskate69: It is interesting that full scale is starting to copy some model 3D maneuvers. I think Kirby does something called a Cobra. Never seen it but someone told me they saw it on Ripley's Believe it or Not. I don't know this for sure as I got this info third hand, but I sounds like he pulls to a wall, hovers breiefy, and then pushes the nose back level to fly out.

As for why there isn't more full scale 3D. Sure, some maneuver like a blender would probably extrude the pilot thru all thier orafices not to mention gyroscopic forces would probably bend the crank. But as for stuff like hovers, harriers, etc., I think a lot of the problem resides in the fact that many of these maneuvers are outside the envelope of the plane. I doubt expo or anything like that has anything to do with it. Besides, you could easily get expo mechanically in a full scale. As full scale starts to mount more power up front, and airframes become lighter, I think we will be seeing more and more 3D stuff from full scale.
