I have never had a bad arf. I'm sure if I keep buying them, I'll get a bad one just as I would eventually get a bad kit. I hear so much about how shoddy arfs are. I just don't see it. I think if a person does a little research, he will be ok just as in everything else. We have a couple of people who love to bash arfs at our field. Neither of them are very good pilots. I think the two sort of go hand in hand (bad pilot - arf basher). That's been my experience anyway.
