I got my quick-release kit from Dronexpert.nl yesterday. I followed their video instructions for removing the Vision+ camera, installing the quick-release plate, attaching the camera to the Vision+ sleeve, and reconnecting. I flew it, and everything worked just as it did before. Then I tried to do the same for my new GoPro Hero 4, but their video instructions didn't show how to install that. I found DJI's instructions for installing their HD-3D gimbal to a standard Phantom 2, so I followed those. I got everything attached, and when I powered it up, I could see the GoPro's video on the Vision+ app. I now have three problems: 1) The video on the Vision+ app has waves of video interference. This occurs both with and without the HD-3D's anti-interference module installed. This occurs when I am recording at 4K and 1080p. This doesn't make the GoPro unusable, but it is disconcerting. 2) I am unable to tilt the camera with the up and down buttons on the Vision+ app. I am able to tilt it by pressing the button above those and tilting my phone, but it takes about 20 seconds to tilt the full 90 degrees. I have not installed the tilt lever on my remote or the Y-cable on my copter, but the phone-tilt success indicates that that is not necessary. Update: Dronexpert.nl sent me a firmware upgrade for the quick-release that solves this problem. It was specific to the Android version 1.0.54 of the Vision+ app. 3) When I fly with the GoPro, the copter shakes and wobbles something fierce; the resulting video is virtually unusable. It seems like a balance problem, but I would assume that they would have tested this before shipping it. Update: I was using the wrong set of dampeners. I had installed a black set that came with the HD-3D, which turned out to be too weak. I installed the white set that also came with the gimbal. They are much stronger, and have solved the shaking/wobbling problem. I have asked for help from Donexpert.nl, but haven't received any help yet (Update: yes I have). Has anybody else tried this out?
