DJI Zenmuse Z15-GH4 HD 3-Axis Gimbal for Panasonic GH3/GH4 (open box)

This DJI Zenmuse Z15-GH4 (HD) gimbal is basically in new condition since I've never used it. Two years ago I purchased a large hexacopter and the seller included the Zenmuse in the deal. I've never used it because I was more than happy with the camera/gimbal setup the drone came with. So I shelved the Zenmuse, thinking I might use it for another project down the road. The original owner was unable to calibrate it for use with a custom-made drone. So apart from a few unsuccessful attempts to set it up, the gimbal has been sitting in a box. This is apparent when one takes a closer look at it. As it turned out, I no longer fly multi-rotors and my interest is now in fixed-wing UAV's. As a result the Zenmuse is now just taking up room. It's a shame because it's really just an open-box item and everything is there: all the cables you will need, the GCU, and even some spare parts and screws, as you can see in the pics. The only thing that is not original is the box I will send it in. For the sake of saving on shipping, I am going to use a smaller box than the original.
