§ I always tether the camera to the bike or to me just in case
§ Be especially careful when deciding where to mount the camera. You cannot re-use the mounts sticky stuff and a GoPro grab bag
with extra mounts set me back £20
§ Be prepared to be spending the first few attempts getting the settings right.
§ If the camera is upside down, make sure you have it in upd mode. I made that mistake

§ 3 1/2 hours of filming will cost you approximately 7gb and 4 energiser ultimate lithium batteries
§ Try and choose when you put your camera on. Save it for the twisties as the motorway stuff is boring
§ I sometimes take my net-book with me so I can admire the results whilst out and about

Note: I am producing a helmet mount video from some older footage. I'll post it here once uploaded.
