Issues with my drone

Hey guyz. (The video of the flight trials, is my own comment, since I can't seem to upload both vid and photos) Anyway, straight to the point.I (15, so not a boomer or anything) have been playing the Stranded campaign for a bit. Rn I'm trynna get the propeller from the volcano. But my drone isn't flying straight nor is it steering right. It kinda keeps on nose diving, and when I compensate for it, it either nosedives in flight or the front end refuses to get off the ground. Can y'all tell me what's wrong?
