I have been flying a Phantom for 3 years now with no problem regarding photos and videos. I also got a Q500+ about a year ago followed quickly by another gimbal to take the GoPro Hero4 Silver. Now the GoPro doesn't like my basic card and I was wondering what others use, in what camera and the results they get. I didn't give much thought to the more expensive cards until I got the 'sd error' come up. Maybe I can improve the editing quality. Thanks guys.
