You guys are really on top of it. Great info..
I use a computer radio and set up Expo. Some don't care for it, but depending on the kind of plane, Expo seems to help smooth out stick transitions. I prefer flying when its windy, unless it's a major crosswind. Those conditions can wait for future flights. Oh yeah, nice to maiden with a reliably running motor.... otherwise, yep shoot for the sky!

Arf's are pretty good at being close enough. These things are mass produced, but still have some amount of jig set up. Pretty much all my planes are ARF's unless I can talk someone out of one of theirs.
