If your club requires you to be a member, then it is the club's requirement and not the AMA.
This is incorrect. If your club is chartered with the AMA, all flyers, members and guests, are required by the club charter with the AMA to be members of the AMA. In the event that something would happen, the club's insurance is invalid if the incident involves a non-AMA member. If the AMA is not a monopoly, why did it go to such extremes to put the old Sport Flyers association out of business a few years ago? As I have said many times before, most clubs can not afford to purchase liability insurance on their own for their flying sites, therefore they charter with the AMA. The AMA had a captive audience until park flyers came along. Maybe now we don't need them as much!
