Just recently upgraded to the V2+V3 from the Phantom 1.1.1 with GoPro and antijello mount. I love the V2+V3 but the low light/night video is poor on the DJI camera. After much research I decided to go this route. I looked into the Dronexpert method to swap out, but for the Dronexpert hardware and then a Zenmuse gimbal I was looking at almost another $800 Additional cost. I already had the Gopro 3+ from my prior DJi set up so I purchased a carbon fiber accessory plate (sold as a mount for transmitters) and a carbon fiber antijello plate kit along with the GoPro mount, all for under $50! The GoPro can be mounted in the waterproof case as well as photographed. So for the times I may require better low light photos/videos and still benefit from the Dji Vision app (and the FPV Booster app which I love!) this is a much more cost efficient method for me! I can also shoot both cameras at the same time. Just sharing this for others who may be thinking of a similar set up.
