For the cost of some ARFs what do you expect

If you take the ARFs for what they are intended for they are fine. They aren't "high performance" or "scale comp" models. I have had good and bad with ARFs and kits. Some my fault and some not. Many of the kits made overseas have had terrible glue joints because of cheap brittle glue or lack of any glue. All you can do is check everything that's not covered and hope for the best. Kits are great if you have the time. Many of us don't have the time or patience to build kits. I like flying much more than building, so a bad kit here or there is no big deal as long as my components aren't ruined when the plane crashes
I applaud those people building kits and wish I had the time and patience to build them too. Maybe someday when I retire...yeah right!
