I'm having an issue with my h3 3d gimbal and the Go Pro Hero 4 silver camera - when the Go Pro is connected to the Phantom 2 via the USB port 20 - 30 seconds after take off the Go Pro freezes and stops recording whilst in flight. I have tried the following: 1) My Go Pro and all latest Phantom firmware updates have been applied. 2) I'm using a class 10 approved by Go Pro memory card. 3) I can't replicate the issue when the motors are not running but the Phantom is powered on. 4) I also don't seem to be able to replicate the issue when the motors are running without the props attached (for indoor testing). As soon as I remove the USB cable from the camera, I can record video perfectly when flying. This is frustrating issue because I really want to upgrade the phantom to do some FPV via a black pearl monitor. Does anyone else have any other suggestions? Thanks, Phil.
