Ive tried flying formation and although i can do it, sometimes i 'lose' the plane ive recorded if i overshoot or whatever!! As suggested on here to me in another post, slew mode is your friend!
How ive been doing it:-
Get the plane you want in the position you want by flying it there (or you could slew it there, or use map view), then PAUSE. 'Y' to enter slew mode, un pause, where i make little adjustments to height and attitude and so on. Then i record this for say 30-50 seconds.
Save the recording, out of slew (or stay in slew it doesnt seem to matter) then change aircraft to whatever i want to be in the shot with my first aircraft.
Once thats done, with everything paused, i enter slew mode again. Then i start playback 'playback as ai traffic' or whatever its called, so the original aircraft is on top of my new aircraft. Using slew mode controls i then slowly move my new aircraft away from the recorded aircraft until i get it in a position i like! Then i use walk n follow to move around as i would normally and take the shot.
Its a little tricky, sometimes ive unpaused by mistake (the pause un pause bit is fiddly ive found) and ended up 50 miles away from where i wanted to be! But just play around with it. I did some ground stuff first to get the hang of it.
Hope thats of some help, if a little complicated!
