Its fairly simple if you take it one step at a time.
Backup your bf2 and pr directory as said in the download instructions as pr will not work if you alter even just the bf2 directory for this.
Anyway this model worked fine for me, I flew it while viewing Oleg alongside and the computer controlled third ka50 also. At the same time I recorded the video and hosted the 30 bot co-op game.
I guess it should be tested on a pr map also, something like fools road should be a good test as its hard on the fps allready Any chance you could mod up a server.zip for that Oleg
Maybe pr_sp could start using this model or the training mode, get it into circulation on pr maps as a way of testing
Only negatives I could think of is the laser guided missile lock is the same as an AA lock tone for the heli, confusing. But I think PR would want this lock done manually anyway as it is now.
I managed to go into free look mode while flying, I think it was the F12 key. So the heli flew off while my own view stood still

Just a camera mode PR wouldnt have anyway I guess
