this can actually be 2 hobbies at once; building and flying. of course some do only one of the hobbies mentioned here; flying. that's ok, i have used arfs to get back into the hobby after a decade or so layoff but now i have a build ongoing at all times. and there are many projects waiting for me to get to.

There is no comparison between arfs and cutting, sanding and gluing a stack of soft balsa and plywood sheets into a hardened gleaming painted model. i love it.
