The P made me trouble, if you get this done is cool, as this was a mayor problem I had. I tinkered so much,
that I forgot how I built that up, hence can't ell where to pick. There where many FM versions and only one working in BAT.
Open Canopies, easy,
In the BAT Section I explained the Yak no Open Canopy problem, the Trick is all the Files you find here, load atop FM/Air Classes,
search for the BAT Killer classes, just to be sure. To really open all, even P, download every one, And all Yaks open their Hoods.

Download each File, one is hidden under simply named Yak, a 9 version you need too. So be aware to load everything and check.
