Just got a new Q500 4K. Charged, setup, calibrated, updated firmware. 1st test flight was awesome. I had the SD card in the camera and hit record multiple times on the first outing. Finished the battery, came inside, put the SD card in my macbook and nothing there. I'm using the SD card that came in the package. I had copied off the tutorial videos and PDF's so it was a bland SD. I'm wondering if it has to have a DCIM or similar layout? Anyone experienced this? I've ordered a couple new 64GB cards to arrive this week and want to make sure they work as well... Thanks.
