I,m looking at mounting my Hero 4 Silver on my Connie. I have a mount on my helmet(side) but as there is a foot of snow and - 20c so a test ride is out . One thing I have done is install the Gopro app on my Windows phone, Its a Nokia so I use Nokia's DRIVE GPS so the phone already has a mount on my handle bars. The App has a Remote function and the camera view is also shown on the Phones screen so we shall see how it all works out.
Be advised, that app will suck the life out of both of your batteries. It may be better with the bluetooth function instead of wifi, but still...
