Finally, after 3 failed attempts I managed to get out this weekend!
I had the Go-Pro mounted to the A-frame with the rollbar mount, although I think I need to move this onto the top bit to get the camera a bit higher.
Also, the video cut off after (it said 1 hour 26 mins), there was plenty of space left on the memory card and the battery seemed okay too. Also the camera split the video into 3 sections of 17 mins (approx) each, which clearly doesn't add up to 1 hour 26 mins!!! To make things worse, the best stuff was towards the end and for some reason this part was corrupted! Has anyone else had any similar issues?
Here are the videos (in 1080p):
