Hello,
Finally, for some months ago I was ready to enviden my AC-range with the B757.
I started to look at the CaptainSim 757-family. However, I did not understand the contents of each BLOCK.
OK; base-pack-this is required I suppose (not clear when reading the product descriptions in Simmarket).  Expansion pack 753, which I assume has a BLOCK # (no idea which though), is of course the 757-300 - no problem understanding that. The same goes for the freighter expansion (BLOCK ??).
I want to buy all that.  Then, BLOCK F; it's a photo of an FMS, but what exactly is BLOCK F? Does it belong to the old Express Line and is not required for the Pro Line as it is build in now in the base pack? If so, why is it still possible to buy as the Express Line is discontinued....?

Well, back some months ago I abonded the CaptainSim site because of this confusion.  Unfortunatly this made me vulnerable for the overblown advertisement of Quality Wings B757-pack. I bought that. That product offers a good exterior model and that's about it - it has  quality wings...

After so many years with my aviation hobby I have got far more near to the reality, so I obviously need more professionalism to the B757 simulation than another company can offer.

OK then, I'm back to CaptainSim, from which I allready have the C-130 for some years.

After this extensive introduction I kindly ask;

I want to buy the whole CS B757 family ( 757-200, 757-300, 757F):

Do I need to buy this so called BLOCK F and what does this BLOCK add?

Regards,
Carl
