Import model into unity

Hi There

I am new to Unity and C#.
I have been fiddling a lot and decided to import a model that I downloaded from - https://free3d.com/3d-models/

But when importing this it is massive. it is also not rotated correctly, if I change the position to 0.0.0 it does not go to the start.

then if I move it to my start 0.0.0 and try to play with rotation, the rotation is still where the object started and that is far of.

What am I doing wrong… or is this normal?

I am by no means an expert. You could try creating an empty at 0,0,0 and drag your model from the project tab to the empty in the hierarchy.
If that fails or is not to your liking, you could also import the model into Blender and see how it acts. I suspect that it’s origin may not be set to center mass of the geometry.
Here’s a Youtube video of how to do that: https://www.youtube.com/watch?v=q_SiM8PIXtI

Hope this helps.
