I have the nano, and I've shot 3 weddings with it now. Nothing about it is damaged, and it's picked up some pretty good shots for me. I'm usually using it without many attachments (I have a cheap hotshoe mic I use for picking up emergency sound if I decide later that I absolutely needed something) but with a T2i and a 17mm prime, it has worked pretty damn well for me.
I'd imagine the flycam 3000 would be just fine. I'd probably recommend picking up a quick release plate for the top, though. Trust me, it fucking comes in handy.
Have a nice day, Bluename.
