I have 2 GoPros and one ION airpro 2. I am going to get 1 or 2 more ION's though and stop using the GoPros. I have had more problems with the gopros recording right and to add to that they are expensive as we all know. The ION is like $45 on Amazon and does great. I have far less problem losing or breaking a $40 camera than I do breaking a $400 camera. As far as where I have mine mounted....I have one facing back on the cross bar behind the seat. One facing forwards on a extra cross bar on the front tubes and one facing into the cockpit on that same bar.
