Joneshd3488, the problem is not in removing it, but sticking it in. You can insert the card between the case and the SD slot (a miss) and it just drops into the case.
I had the same thing happen on a 64GB card of mine. Rattles around inside like a pocket full of keys

I have to go and buy the Allen key set with the hole in the middle so I can open up the back and take it out. Not happy, not blaming yuneec or anyone, But, I've never had this happen with any other Micro SD card/slot. Still, its a learning process. I hope I don't damage the ST-16 when I do the open heart surgery to get the card out.
I'm sure I could take it to yuneec and have them do it, but I just want to get it done, So I will do it myself over the weekend.
