RE: Using a helmet cam for in flight video?
Hey Tex!
I just wrote a big explanation and you summed it up in three sentences-grin. The main factor is getting your antenne pointed in the right direction and using a good quality camera. Capturing, copying, and presenting/burning the videos after editing will cause most of the quality losses. The wireless link takes a little work, but after you get it perfected... it will be the last thing to worry about when it comes to quality aerials. I have asked the very same question you are asked about the quality losses due to RF etc... I never got a good answer either. I say, put your helmut cam in a plane and let her rip! At least it's protected-grin!
