Why would you not consider it modeling? I think is the very essence of scale modeling. Yes there are professional modelers out there that work for airplane/helicopter companies who produce real flying planes. I know someone who gets molding jobs from them from time to time. Those modelers have been there all along. I think it would be really cool to have that level of ability and patience to be able to have that as a profession.
I personally don't consider it modeling because it's not something people with average resources or income could consider doing. It's something built by professionals for a purpose like making movies etc.
This is out of the realm of what I consider modeling and into the realm of professionals for the purpose of selling something or making money from.
Beside if I was to spend that much money, time effort and resources I dam sure would build something I could fly IN...not watch from a transmitter perch.
However I'm not necessarily raining on anyone's parade...to each his own...it doesn't mean I don't think it's cool or spectacular...but then so is a full scale F22...I can't and won't try to build one of them either!
