I am not a full-size pilot myself. However, being a RC modeller for 30 years I also do question the increasing size of some RC models. Flying giant models safely basically means flying them in an isolated airport with full size aviation permitting. Models always give way to full size aviation, so you may have to wait.

It also means multiple amount of investment and fuel costs. Also a place to store them. The world is looking for ways to reduce emissions. Having the need of a giant van, driving it for hours to burn more fuel with a giant jet is not sustainable future. As you can have it all with a smaller model, at a field closer to your house and be flying more frequently.
