Well, yea. Of course I did. Look who you're asking. haha
You can see it in this picture:
The aluminum bar going across the cage is where I mounted it. It is set at a height so that the camera looks down the hood of the car as far as I can, and is mounted exactly opposite of the driver. This way the camera is seeing exactly what I am. The little camera is small enough that it doesn't take much to hold it there.
That video catches one of the rare instances where my car actually launched straight, lol.
