They come with a bunch of mounting plates and stuff, and they sell extras... my favorite has been
the simplest... I put one of the stick-on plates on the left air-wing...

my non-hd one can take 45 minutes on a 2 gig sd card, and 2 gig is all it will take... don't know
what the limitations on the newer hd gopros are... wouldn't be able to put 45 minutes of hd on
a 2 gig card, but maybe they support bigger cards... 45 minutes of video is a lot, and it is
kind of a drag editing video on my wimpy laptop... those are the kind of things you'll end up
thinking about... a studly PC with fast disk drives and a lot of memory is a good video editor.
You probably need to set the microphone to "low" (or whatever they call it) or you'll end
up recording noxious wind noise instead of sweet Valkyrie sounds...
