And we are back at square one where the whole point was to go multirotor to avoid the gearbox and cyclic pitch complexity.
In a car, it's a bit similar thing. With a combustion engine it optimizes to a single engine with fixed + variable ratio and shafts to the wheels and things like differentials. Lots of places to have oil, to maintain, to break, being heavy too. Tesla has 1-2 electric motors with a fixed gear ratio of about 10. Some concept vehicles have a direct drive motor near each wheel or even inside the wheel.
The electric motor has different characteristics than a turbine or a piston engine. Hence it can affect the whole machine design.
