I prefer flying. I've been doing this stuff for 55 yrs & I've built many hundreds of models -- some are my own creations, others were/are kits, plus ARFs as well. I'm a bit tired of spending my life in the basement, so I don't look down my nose at ARFs. Some are pretty good, & the not-so-good are easy enough to quickly bash into something better. To me, flying is the point of the whole business. I love carefully crafted models -- they are beautiful things, but ARFs can get and keep you in the air with a minimum of effort & time -- they have their place.
