I know it has been a while since I have uploaded quality content (shameless self-praise there), and I have been and will be very busy the next few months due to college projects. So I'll just give you what I have for now.
This is the concept art for Real Engines (Russia/USSR), designed for SFS' future Real Solar System mod. Enjoy.
(There's still some more stuff to upload, so check the comments for more info, there is also a small link to how the engine will look when fitted onto a fuel tank, and attention to detail is my number 1 priority!)
