Need Help with Flying Mount Controls [Solved]

I have a flying mount added, but need to be able to control the vertical position.

I know it has something to do with overriding the YV motion vector, but it seems most of the answered version of this topic have had a major explanation or detailed image of the solution deleted.

Have set up key binds for the processes, and trying to get the processes themselves to work. However, not sure what all actually needs to happen within the process.

Edit:

Took a while to find, but found a tutorial that is still mostly valid and includes add missing information.
