I went to buy a new 32GB Micro SD card today - NZD $70 on special. Took the 4 GB card that came with the PV out, it was a little tight. Plug in the new card, it felt a little funny, normally the are spring loaded, and you just push it in to get it out. It didn't feel right and I couldn't even get it out straight away. I got my PV yesterday so I was quite keen to get out and fly with the new toy So I was thinking, ok I can fiddle with the card when I get back. Went out for a fly, had the video started already at take off, everything seems ok. I had a minor tip over on a landing, nothing special. Took it up flying again and wanted to take a photo, got the message on my phone "No memory card" Took the PV down and looked, no memory card???? As I wrote earlier I couldn't even get it out with my fingers, and now it had come out by itself! I gave up looking after it, you know how small the are. So I had my new card less than an hour. When I came home I tried to put the old card back in and it felt right with the lock. I wonder what have been wrong. So from now on I will secure the card with a little piece of tape.
