RE: do arfs belong in scale forum?
There are two forms of RC airplane models. One is scale. The other is sport. All models will fall into one of these categories. How can you tell what your models is ? Its easy. If your model is a miniature replica of a real airplane, then its scale. If your model doesn't look like anything flown in the full scale world, then its a sport model. A 4 Star is an example of a sport model. There are no real 4 Stars at the airport.
ARF or kit or scratch or witchcraft, it doesn't matter how you obtain your airplane, if you are interested in learning or sharing techniques used to achieve scale effects, this is an appropriate forum to do so.
