well if you add an "F35" which we have not recived yet, or have we?!, or have we not?!, who knows? ^^ , and then add the AH-1, wont make any sense to me, but its your call and im grateful some one does a mod with new modules\re-texture.
no we do not use MD500's for quiet a while, even when we had, they were never really used in the past 20-30 years, as in real action. so no i don't think you should add them, due to the fact IAF does not have any counterpart nowadays.
the IAF used UH-1N i even have a photo of a scrapyard next to my workplace back in AFB 6. we do not use them any more, for quiet some time.
here it is, took it back in end of 2011 when i got stationed at AFB6, http://i.imgur.com/TjM4K1P.jpg (710 kB) you can see the UH-1 and some old trainee.
i will upload some of the photos i have from the pilot graduation at my base a couple of years back, for reference, (Aircrafts,Camos,AA). and maybe some more, if i'd see it appropriate and not "for your eyes only" info.
