Fly height not being applied?

Fly height not being applied?

I am making towers that look like bladed spinning projectiles (like huntress's attack) by changing the model but they are partially underground. Simple, I make it flying a little bit. Only problem is when I increase the value Movement - Height I can only see the changes in the editor; not in-game. Does anyone know how to raise fly heint any projectile model? Thanks.

Edit: Please disregard this question; the solution is Movement - Height is only applied to flying units that DONT count as buildings. Thanks anyways.
