Great job either way.
I unsuccessfully tried to create my own personal R-77M mod, since the basic version in the game seems to have unreasonably high drag characteristics.
And perhaps for the future, it would make more sense to have an R-77-1, R-77M, and the ramjet R-77ME (the so-called "izdeliye 180-BD"), which seems to be the further development of the RVV-AE-PD.
