There isn't any indication of intermediate gearing, or are you referring to the turn tables themselves? My guess, like many early VTOL projects is they had the number of engines they had such that the loss of one or more of the engines wouldn't be catastrophic. Still, that many engines seems risky for the time. However, given the reliability of today's engines, I could see this as doable. But, there are probably better layouts for the lift system with today's powerplants. Such as, just having two engines on each side of the fuselage, an F-35 lift-fan type system, but that would take up so much fuselage volume, I don't know that it would be worth it. Having said that, I find this design very cool, especially how well it compares to a standard aircraft in the low altitude regime it is meant to fly in.
