I am researching gimballs for GoPro 3+ I want to use the Zenmuse H3-2D as the base for a hand held steadycan for my GoPro 3+. Does the H3-2D supports the GoPro 3+ ? Can I use the Gimball in standalone mode with the right 12v power supply ? Does it come with everything needed to run ? What else does it need to work ? I am not able to get any support from GoPro, how is the support from DGI ? Thanks !
