I have been building for over 27 years and have just done a few ARFs. I hate to see a newbie bring one to the field. Some are OK, but some are really bad. I have seen so many with joint problems, firewalls come loose and stuff like that. It is easy to fix if you catch them, but how many are flying around and don't know what to catch. It just teaches newbies to fly lesser quality stuff and not care.
