All this talk and no one has stated the obvious:
1) We need ideal batteries; a pure voltage source with no internal resistance and infinite current capability
2) We need ESCs with 100% efficiency. FETs need to have have infinite slew rates, 0 rdson, infinite gate resistance, infinite frequency response. All the copper has 0 resistance.
2) Motors are 100% efficient; no copper losses and 100% of all magnetic flux is utilized. And, the rotor would be made of superconductors since they repel magentic field, so no need for magnets.
