I was a member of Sport Flyers years ago. The problem was that the AMA had all of the flying fields and as a SFA member I was not allowed to fly at any AMA field or attend any AMA flying event even though SFA had more insurance than the AMA did. This is the reason that another CBO will not survive. The only way it might make it is if it is for Quad copters only and not at an AMA field.
