RCG is RCGroups.com. Lots of good info on there too. The Perry show is in March:
http://www.gamarc.com/georgia.html It is a HUGE swap meet with lots of vendors and lots of guys trying to sell or swap their stuff. It takes up three buildings at the fair grounds down there. That's a good combo for fighting flutter in the ailerons. That should pretty much take care of it. Good price on the coro too. I was paying $12 a sheet for 4mm up in Newnan, but I haven't bought any in over a year probably. I haven't been building much lately, but hope to get back at it soon.
