Here is a new adaptation for FSX of the add-on of the Russian Bombardier Tu-16 Badger, nice 3D modeling with VC and 2D panel, possibility of releasing several kinds of bombs
Superb TU-154B2 by Project Tupolev with the colors of S7 Siberia Airlines livery circa 2008, Virtual Cockpit by Thomas Ruth. Repaints and textures by Stephen Browning, assembled by Ricardo_tv.
Here is probably one of the best freeware add-ons on Internet, the Tupolev TU-134A-3 with turbofan Soloviev D-30 engines. The cabin and cockpit are fully modeled in 3D with HD textures
Legendary Tupolev TU-144D (which looks like Concorde) for FSX and FSX Steam and Prepar3D v1,2,3 (not compatible v4).
Here is the Tupolev TU-114 and TU-126 (126 being the AWACS model). This package is a special version that has been updated specifically for FSX by Andreas Rotowski and includes many improvements and updates.
One word: "Wow !" you won't see an add-on where the simulation is so high anytime soon, certainly the most developed and the most complex of all freeware add-ons for FSX and P3D.
In the tradition of Russian aircraft, here is the Tupolev TU-124, a beautiful model with custom sounds. There is no VC (virtual cockpit) but it is not what matters most, in fact, this add-on is primarily present for his 2D panel which is very comprehensive
