Here is a test video of using the wide base mount for a better 3D effect in objects that are more distant from the cameras than using the normal 3D GoPro system, The cameras have been mounted on Vegetoast1's new Quadcopter after the previous one went for a swim - you can see that video on his channel with many more excellent quadcopter FPV & 4WD videos.

The cameras have been mounted using a vibration reduction GoPro mount designed & built by Vegetoast1.
