it's a good unit.. I have the larger one (since kickstarter).. 720p is "ok" really did not capture a plate all that well when I almost was head-on'd by an SUV.. see we were moving away from each other after the pass so it was tough to focus. With the vehicle approaching from the rear = no problem. I also have the rideye (another KS project) that will be my 1080p front cam.

max memory card on my fly6 is 32GB... but that will get you like ~5-6 hours I think.
