While on the subject of 32g cards, do you actually think you need a card that size?
I have always and only worked with 4g on my quad's. I pull all the data from it after each flight. I also use the data logger on each flight so that if the video is something special it get's placed in a folder to set used with Dashware. Even though the data logger can save numerous files, I still pull that data after each flight as well. I remember when I lost my 1st quad due to a fly away. I was more upset over noot having the video I had taken during that flight, then I was about the loss of the quad. And then,....I lost another quad. And that also had a flytrex core2 which means it was more data I lost. This stuff took place when I was doing a lot of test flights and the data I was gathering at that time had a lot of meaning to it.
Btw, we also started getting forced updates a couple months ago. And you never know what will happen with any data you may have saved on a card. I think the last forced update was something to do with the camera on the vPlus. Anyway, since the getting updates without my approval happened, I tend to check DJI's site before hooking up my quad and running the assistant.
