Would it be possible to post this altered lua file? I can't seem to figure out what exactly I am supposed to change here.
Look up this file in your install directory
Mods\aircrafts\Uh-1H\Cockpit\Scripts\mainpanel_init.lua
Open the file with Notepad. Press Ctrl F, write "vAngle" in the pop up search window. I found the entries at the end of the file, probably you will too. Look up where vAngle is NOT 0, rather vAngle=15. (plus a lot of decimal numbers), and overwrite it to vAngle=0. Save, exit, start program and holler.
