First flight, and some questions

Just to be clear - I did watch a bunch of footage and reviews before purchase, and this was one of the drones that was ranked highest in its price bracket, not least because it does have a 3-axis gimbal and good stablisation. You can see an example below, but there are plenty of others.

Lack of skill and wind certainly make up a good deal of the flight. I expect that to improve in better conditions and with practice. My main question was whether or not some of the defects (which actually seemed to be less obvious in the YT upload than in the original) were down to the SD card. I shall do some more testing in some better conditions and see how I get on.
