This set up does not work well IMHO. I use TRP settings regardless of what I am playing. That is:
Go into you hio2 folder and find the db folder, in which is a file that is named misc.txt.
Open this file using notepad and change (my recommendation for balance)
air marshal leads 5 squadron's, with the number the going down 4, 3, 2. for each lower level of what a air leader can lead.
Then change the max size of air stack to 5.
Save as, and overwrite.
