I just found this one after watching a few skydiving videos on Youtube. The parachute could have caught up in the mud tires and wheels if it was me who's gonna try this daredevil stunt. I guess it's is an old ad or something?
that's a cool DIY. have you tested it in sunlight now?
I agree, EOS M is a good buy for $300. but well, the price difference of brand new full kits of canon depends on its features
