Hi everyone. I just bought the firefly 6S because I was using a go pro 3 white and I'm not so happy of the light quality. I saw many videos of this camera footage and I most say I like it. Colors are brighter. So I mounted it on the H3-3D gimbal, but in order to do so I had to make some small modifications on the camera, because it's 1/5 of a mm wider. So I had to smooth 2 sides of the camera and add a cardboard type sheet behind it, otherwise the side botton would be pressed against the gimbal. Once I mounted on the gimbal the problems started. I thought the gimbal itself would auto-regulate itself. In fact when I added a filter to my go pro I did not have any issue. I tried updating the software of the gimbal and the problem is basically that it does not keep the horizontal position. It is horizontal when the phantom is straight but if I bend it as if the phantom is moving sideways the camera align with the phantom and not with the horizon. I tested the quality at 1080 px at 60 fps, and I must say it is was I expected. Just need to fix this problem. Also sometimes when the camera is facing straight the motors starts making a lots of noise. Anyone had a similar experience while changing the camera??
