Will flying slowly consume less power for the same distance? If this were a car the answer would be yes. But combustion engines are super inefficient. Conversely, I’ve often read that running for one mile vs walking for one mile consumes nearly the same amount of calories. It’s just that walking would take you a lot longer time to cover a mile vs running. So what is the Phantom like? A car or a human? I know that going faster creates more drag so faster would be less efficient, but is it super noticeable or not? What if you neglect air resistance? I would expect you lose more energy as heat in the motors too; but is it all very noticeable? Or is the difference so little that it is worth cranking it up to full speed just to save time?
