Someone is giving me a new Hero 4 Silver. I have a Hero 3+ Black. My question is .. Is the Hero 4 Silver edition compatible? I don't have it yet but I think it may be heavier and maybe even thicker because of the LCD. Is anyone using it on H3-3D? Also, are people successfully using Hero 4's at 4k with no jello? I haven't been following threads on Hero 4 as I just found out today someone was giving this to me. Thanks for the comments.
