Need guidance_new guy!

So I have been playing around with an STP file that was given to me by a friend. I would like to eventually 3d print it. The issue I have is that I cannot figure out how to make the tail stand vertical from a folded position. Again, this is an STP file. It imported correctly, definitely a lot of moving parts, is it even possible or do I need another program? Tried to upload but I can’t. Sorry.
