I think you are probably correct about creating an easier to fly helicopter using a intermediate processor. I also think the argument of longer flight times due to less power draw may be true also. But cheaper and fewer parts I'm not so sure, part of the reason drones are so popular is the low parts count and part price. Most low price hobby copters use 3 motors, driving two opposing rotor blades for stability and a tail blade for steering. There are also several gears and bearings to support their functions. Far easier to strap 4 motors with props to a cross and drive them using a solid state SBC integrated with RF,6 axis gyro and 4 power transistors. Many of these new hobby drones use all the same parts across several different manufacturers so there is an economy of scale to considet too.
