OK, I know it's not F125 related, but I though you chaps might be
interested anyway. If not, plese let me know and I'll crawl back under
my rock :)
I recently participated in the Greeley Grand Prix. The course safety
was a ahrk back to 1950's F1, but it was super fun nonetheless.
I used a Chasecam attached to my helmet and got some pretty decent
video. I had to compress the cr@p out of it to get it down to a
reasonable size, but you'll get the idea.
