There isn't really a set trim as I've understood it. You can see what your stabs are set to on your DDI by going to SUPT then FCS. You can see what it's at and maybe when you do your timing you can then look to see what it ends up being. From the vids I've seen you are going to trim a lot so it's more by feel than a set number. It also will depend a lot on your current weight with fuel, gun ammo, bombs/rockets etc. You can see your total weight from the DDI again, SUPT then CHKLST sub-menu. It will show A/C WT. If you are landing on the CV, make sure your 33,000 or less. That will also make trimming and such a lot easier. I hope that helps some?
Edit
That is not showing trim and I don't think there is a way to show what your current trim setting is. Still looking.
