Having been a kit builder since the age of 8 and now going on 70, I find that their is always an area that can be improved upon. Whether it be a kit build or an ARF. We all like to add our personal touches, or should I say our personal improvements. Its all part of the hobby.
I have never considered that I was putting in too much time on any ARF, that I have assembled. I just felt that it was time well spent in order to have a stronger, better and longer lasting model.
With all this said, you build a kit. With an ARF, you are assembling.
