i recently changed the tail on my align 470l. after i got everything back together i noticed the belt tension was extremely tight. i then went to go adjust the belt tension and noticed the screw is missing. anyone have any ideas what i could do as this never happened to me.... thank you for your time

If it is just the screw that is missing, then you can get either an M2 or M3 screw and replace it to ease the tension on the belt. Definitely be sure to use thread locker on that screw. I worked on a 500X that had the belt tension system like this and it was missing a screw on one side. It still flew fine, but the belt was quite tight.

Can you post pictures? If the screw is missing then the obvious answer is to replace it. Not owning a 470L I'm curious to see how a missing screw would make the belt tight.

Here is the manual diagram. I had never seen one either until I worked on that 500x. Back in the day, you had to just pull on the tail boom and tighten down, but not too tight or you would crush the tail boom lol.
