I had taped on an hd camera once on the side of my helmet.
The stuff I got was not bad but I found it would be better if mounted in the center of helmet so it would show where you look better.
Also it had built in sound.
The wind noise sucks.
I think it would nice if you could have a seperate mic and put somewhere by motor and sheild it from the wind somehow.
That way with no wind noise and just the rummble would be great.
I tried it motion activated with motion stabilization.
The motion stabilization made it look kind of robotic and raised havec with the motion activation.
Ended up with a bunch of real short clips.
If I kept my head moving lots then it kept recording.
Going to try again without motion stabilization.
Hope it will be better.
