B-52 has been done by PierreDeveaux for his non-SB/FD project, and is due to be FD-modified by me (it was supposed to be done already some time ago, but I moved from Poland to UK inbetween and all my plans for doing stuff got delayed).
All Soviet aircraft You've mentioned are on my to-do list. Some of them were started by Guillermo2312 and later WiP's were transferred to me (including Tu-22 and Tu-160 - that last one is VERY advanced WiP). Still, for the reasons mentioned above, I need to ask You for patience.
I'd like to be back drawing SB/FD stuff as soon as possible, but because of the amount of recent changes in my life I still need to have lots of things sorted out. I'm hoping, though, that already in the nearest days I'll be able to start "returning to drawing board".
Woah, not that i'm being too impatient, but rather i'd call it some kind of slight nitpicking, as the aircraft i mentioned are well known ones, and i'm surprised that it hasn't been drawn in FD Scale yet. But it's ok, I could wait, i could wait forever...
