ARFs have their place. A number of times I would have missed chances to fly if I had to wait until I completed a kit with the hit and miss weather we have here but they will never stop me from scratch or kit building. I have 2 scratch builds going at the moment. An extra 230 and a Sr. Telemaster.
The satisfaction I get from flying something I built from scratch can't be matched by ARFS and I think that can be said for all the builders out there.
However there are a lot of flyers out there that would not be out there at all if they had to build and they do add to the hobby in many ways so I welcome them and their ARFs.
Bottom line if you are out there and you are having fun you are doing it right whether you are doing it my way or not.
