Your probably fine I've flipped mine twice... just make sure your props are still snug and I'd calibrate the Imu and compass. If your getting some gimbal jelly I'd calibrate that as well
If it does not look like the video it probably failed. I'd give it another minute or two and check the USB file for a text log to see... don't sound like it took the update but don't pull it too soon and screw things up more lol
If you pull it directly from the bird, I'd let it sit 15-20 min as they are pretty warm right after flight. I always just make sure they aren't hot or very warm before charging just to be on the safe side since these cells can be finicky
It probably won't work via bluestacks that layer is keeping the signal from going through properly I'd bet... great idea though, bet you play clash of clans too!
Do you mind sharing what kind of copper tape your using? I've downloaded the file to go get this printed, just curious as to which tape you've found to work best?
