GoPro here with several of the self adhesive shoes mounted in various places. They work great.
Here's a video I made today with my new belly mount.
http://youtu.be/7Cxm8pTyQ6ANotice how I blow oil from the breather after the first roll. I have a Sonex aerobatic oil breather, but it doesn't catch it all when you go upside down.
There's a fun part showing me falling out of the top of a loop into a spin! Fun day just yanking and banking and making myself nauseous. The landing was a challenge too. Crosswind gusts keeping me on my newly hatched taildragger toes.
I also noticed smoking a tire trying to make the taxi way after landing. I shouldn't have hit the brakes so hard and just took the next exit.
