Hello, I have a question about sending my drone to repair. I have an Image Transition problem and I chose to send the whole product set to repair, but I don't know what exactly do I need to send. Controller+Drone with battery or without the battery or any other option, please tell me

Hi there, if there is an image transmission issue, you must send back the controller and drone for diagnosis. If there is no issue with the battery, you can choose not to send the battery back. Please also note to remove the SD card before sending the drone.
