In my case the RTF/ARF's are a godsend. Once I decided to get in the hobby I had to jump with both feet to get in the air and stay in the air quickly.
Once I got in the air I started to build a kit and my goal now is to stay in the air as much as I can, learn to fly the best I can and live long enough to build another kit. And if I finish that one I'm gonna build another.

I think the RTF/ARF's are good for the hobby and all can live happily together.

I always have been the reverse engineering kind of guy anyway.
