I would say get yourself a more conventional videocamera. The epic cams and similar ones have been proven to not be very good in low light. And you would probably be suprised at how much you move your head (if thats where it is mounted), or the shock from the bow would ruin an otherwise good video. Alot of people forget to follow their deer after the hit. No zoom or any other fetures there.

I don't know how you would even use a flip videocamera in the treestand unless someone else was doing the filming.

A better option for filming your hunts would be a conventional videocamera with a tree arm to hold it all steady.

Not trying to knock your ideas, i just think you wouldn't be happy with the quality.
