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.
"Rather easily" compared to what, herding cats?
When clubs that were dual-chartered got the letter from Carl Maroney threatening to pull their AMA charter if they did not require all club members to be AMA members, their choices were rather limited: (1)comply with AMA's demand or (2) "rather easily" break off a new club inclusive of all the non-AMA members, and inform the site owner that he now had another club to deal with for use of his property. I heard of several clubs that caved to the threat and opted for (1), but none that went for option (2).
