I am so sorry! Pistons and rotors have been worked, although rotors are having an issue right now. They no longer cause as many explosions. They've added in oxygen, planets, pressurization, hydrogen and hydrogen thrusters, and the like. Each time they do, I have to go back and redo the Vladivostok for it, but it's nice. I like the idea of an old ship being constantly retrofitted to keep up with the times.
