The AMA does allow dual charters/insurance at a flying site, the AMA is not exclusive nor is it a monopoly.

Maybe you should remind AMA of your facts and advise them to remove [link=http://www.modelaircraft.org/PDF-Files/909.pdf]this[/link] from the AMA web site.

After reading the link given by AP it seems there is a simple solution. Use XYZ R/C Club for one name that you charter under, and XYZ Model Aircraft club for the any other. It was done rather easily when the SFA was around.
