Hi all,
With the release of the new lighter GoPro3 (75 grams) it seems more doable to use the GoPro with a Funjet Ultra.
In my light Ultra setup (600 grams) I was using a #16 Keychaincam with wide-angle lens and by putting the heavier GoPro3 up front I could move the battery all the way to back and remove power cables and two silver coins I had used to balance the plane - in total the GoPro adds just 20 grams.
Here are some pictures of a highly improvsied installation - I intend to make the nose of the Funjet removeable for a cleaner and less draggy installation...
