I love hex’s and Octo’s and X8’s and all of that, but one of the best bang for the buck rigs for the GH3/4 is the ZeroUAV HighOne.
Again, this is not the only choice, I also fly a Zen on a Hexacrafter hex for teh Gh3/4, but for transport and redundancy the HighOne is nice and the Z1400 gimbal is...
