Went to fly, got a no SD message. Shut down, got an SD and started to put it in, noticed that it looked like there was one in - above the slot where it should go. Wasn't positive about that, so I put one in the slot and flew, it recorded and worked fine. Came in put a flashlight and magnifying glass on the SD slot, & there was an SD card above the correct slot. Tried to work it out with a needle and it immediately slipped back in out of sight. No rattle or anything when I shake it, another card goes in and out fine, so I think I'll just have to forget about it, don't want to take anything apart. What do you think? Ed
