Didn't all the Diamants have solid stages too?
gas generators were used not to drive turbo pumps, but to pressurize propellant tanks.
Can someone explain to me how this rocket is supposed to work! A pressure fed nozzle? . Is there a turbopump into the combustion chamber? It cannot be a hybrid solid rocket with three Nozzles.
Have they demonstrated the technology, that's all. As in greater than 10 seconds of a pressure fed long cylindrical rocket.
These are simple questions. I don't care if they impinge upon the professionalism of these guys. I think they are worth answering for the sake of those that have put up money.
Vector have just published the Vector-R and -H user guides, attached.

I'd think they would have already asked those questions before they wrote the checks.
SpaceX Vet’s Startup Readies Small Rockets for TakeoffVector Space Systems raises $21 million to build smaller, cheaper rockets.By Ashlee Vance29 June 2017, 20:00 BST
I doubt Vector will have any problems finding customers once flying. There are a lot Smalsat and cubesat based businesses relying on likes of RL and Vector to deliver their satellites to specific orbits.
That is a bit more than "press" - they just raised $21m from a group led by a Tier 1 VC.Frankly astonishing.

Fair shot at the hockey stick for all involvedWatch Vector start properly building out a real team soon now. Hope they know what kind of talent you need to bring on at this stage

The aerospace industry is divided on how successful these small rockets will be. The price per pound on the large rockets from SpaceX and others is still more economical. But it’s the flexibility of requesting a launch, almost like you’d order something on Amazon.com, that could end up being more attractive than pure cost. “The lower end of the market will be more important than most people realize,” said Rob Coneybeer, managing director at Shasta Ventures. “Moore’s Law is allowing you to make more capable things smaller and smaller, and I think the low-end rockets will hit the sweet spot.”
I say Vector has a much greater shot of meeting a $100m valuation than RL does of a billion.And just the fact that Vector doesn't dismiss reuse means they have more of a shot at reaching hundreds of launches than RL does (assuming RL doesn't change their tune on reuse, which is admittedly a big assumption).
