Hello all, new to drones, new to the site, new to pretty much everything drone related. Long story short, I bought a used X-star Premium that was just the drone and nothing else, no box or anything. I then found a guy that had everything I was missing because he lost his drone at sea. Everything works fine, flys great, etc. I want to register it as I understand I am supposed to but I cannot find the serial number to this thing anywhere. Can someone tell me where I can locate it? Thanks, Kurt
