What does it matter what the full scale guys call it? We are talking about two different kinds of airplanes here. Even the real Zivko edge is not in the same class as a 3D plane. Take a Cessna 150 and compare it to the typical R/C trainer. There are very very few similarities besides the functions of how they attain lift. Dont get me wrong I LOVE full scale airplanes and they are what got me into this hobby but they are in two way different categories.
Im sure you already know this but the 3D crowd has different functions and parts of 3D. High alpha is one of these functions (i.e. High alpha K.E., Harriers, etc.) But in a torque roll there is no forward progression so maybe you can fill me in on the physics of the AOA in this position. There is still some sort of AOA but its not in traditional manner. Plus we have other moves like the blender, and waterfall which are attained by a drastic change causing a disruption of airflow over the wings. The blender is attained at a relatively high speed. The same goes for a 3D snap. The full scales are trying and learning from 3D pilots right now. I saw an interview with Matt Chapman (spelling??) and he said they they were trying to pull moves from the 3D R/C sector but they were really hard if not impossible to do.
