But I'm wondering what the benefit of (or need to) drive the fuel rod is. The hybrid motors I've seen in the past use a cylinder of what's effectively rubber with a hole down the middle, so there are no moving parts needed. I guess it avoids the need to contain the fuel in a chamber but the added weight of the drive mechanism and associated control gear must be considerable.

It seemed to be doing large and fine pulses at wildly varying frequencies, which would make it ideal as an OMS/giant RCS for larger ships, or even as a lander. It's very Kerbal.
