I'm reaching out because I have a drone that needs repair after a recent crash. It fell to the ground during use, and I attempted to reassemble it, but now it won't connect to the remote controller. This has made it impossible for me to operate the drone properly. The drone is currently in China with my sister, and I'd like to know if you can assist with the repair. Could you provide details on the process, including any necessary parts and the estimated cost? I'm eager to get this resolved quickly so I can get back to flying. Thanks!
