I saw that GoPro has a nice new basic GoPro Hero HD for sale at a decent price. I was wondering if these can be used on a Phantom 1? The reason I am asking is it seems like the casing is permanently on it. I do not have one yet, so I am not 100 percent sure. I am looking at using a cheaper either Tarot or Walkera gimbal on this, maybe the stock GoPro mount for DJI for test purposes. Is this possible? Or do I need at least a GoPro 2 or 3? Thanks!
