I saw most of it live. I had no idea that they used an electric motor for the fuel and oxydizer pumps. It must make the engine a lot easier to design and build! And I knew someone was doing 3D printing for engines, but did not realize it was RocketLabs.
BTW, another cool thing: The electric pumps are powered by LiPo batteries (1 megawatt!!!!!!!!). Two batteries can power about 1/2 the (1st stage) flight and then they "hot swap" to a second pair and drop the first pair to reduce wait. Very cool!
