I can’t open the top of my drone to see what is wrong with the “stuck” camera gimbal … The fourth screw is stuck and it doesn’t come out, even with the appropriate screwdriver… Well, I got the other screw out but not the fourth. It is also impossible to remove the top of the drone, even with sharp tools. I also used power to open it, but it is impossible. The top is just stuck on there. Can someone please help me?
