Yep you've got to run it upside down in the chest mount to get enough 'up tilt' I tried the pack foam under mount idea but you'll need a shitload of it. When mounted in upside down you want the angle between the backing plate and the body to be about 45 degrees. Also run the the straps SUPER tight, minimises vibration.I picked up one of these the other day with the idea to run it on the chest mount.

However, I can't angle it up enough. I could flip it upside down and set it to record upsidedown in the menu when the firmware update comes out, but I think the added distance the camera is from the mount when it is upside down would mean that it might shake more.
Does anyone have any experience with this, or how to tilt the camera up more on the chet mount? Maybe pack some foam under the bottom of the mount?
I can't wait for the firmware update to come out....whilst it's easy to flip it in an editing program it's just annoying you can't easily watch the raw footage...unless you hang from the roof anyway
