It's weird that two of my aircraft serial #s (below) don't seem to match (I'm not talking about Gimbal's serial #):
1) S/N on the sticker at the side of the bird
2) S/N shown in the "Details" tab under the right upper settings in the main flying screen on the smartphone

Need help or explanation, please. Thanks!

You should contact support.

Hi, that is normal. Please don’t worry. If there is a need to apply for the ticket or case number, please refer to the one that printed on the box and on the battery slot. Thank you.
