"I think one reason I don't care for it is because I love to watch R/C planes and relate them to real planes. When watching 3D planes it is in the back of my mind that a real plane could never do that."

If you have ever watched a few of the new full scale aerobatic planes fly you will find out that they are doing some 3D I have seen the zivko edge hover, torque roll, tail slide, wall, knife edge spin, a super flat spin.

Your never gonna beleive this but some of the full scale aerobatic guys say that they get great inspiration from watching 3D and it has them out experimenting with certain 3D moves that they would have never dared to try before. Matt Chapman said this on TV Right now he is learning to fly and do some 3D stuff as well. He says its a lot harder than he would have ever imagined.
