As you can see from the picture, my grandson's drone is missing the set screw on the gimbal. Can someone tell me the proper size screw I need? I'm sure I can just find one them on Amazon or at any hardware store, but I don't know the proper size.
I appreciate the help! We're new at flying and we've been having a blast! We've been grounded for a couple of weeks now and my grandson and I are dying to get back out there!
