Helmet Cam

For adults and kids - this water resistant / shock resistant camera can be mounted in all sorts of action situations so you can record the crashes. It’s got some decent specs….
640 x 480 VGA resolution at 30 frames per second, up to 2 gigs memory and it has USB and RCA out.
at $129.99 it certainly isn’t disposable, but it would fit the bill strapped to a R/C plane or car.
You can get it here at Oregon Scientific
