I tried recording some video with a Hubsan FPV X4 H502S Desire for the first time this evening and after pressing the video button got a message on the controller screen that said: CIRCLE FLY. I had put a 2GB mini SD card in the card slot that in the past had worked with a Syma X5C and it seemed to fit okay, but there was no video or photo on it when I checked later. Can anyone explain what happened?

Thank you for any help trying to learn this stuff!
