In your \Aces High\Settings\Planes directory are the (aircraft.hps) files for each aircraft you have adjusted the views and saved with F10. If you have similare cockpits like bubble canopy's or tempest/tiffy, or 109's, Fw's. Zero's, F4U and such you can use the content of a head position file across several planes. Or even try one you like across dissimilar planes. Just save off a copy of all your HPS files to a backup folder. You cannot break anything with these files. Sometimes HTC will tell you to rename your Settings folder and restart the game to produce a first time install state.
I beleive first you will need to save at least one position for each aircraft to generate a head position file. Then copy the contents of a HPS file in which you have everything setup into the HPS file of a fighter you choose over writing whats there. Then spawn on the runway in that fighter and make any additional adjustments. You can edit the HPS files with notepad or write.
At any time you can delete the HPS files to return your cockpit head postions to the first time game install default.
