However, things very rarely work out that way - due to differences in efficiency. For instance - the nCP X uses symmetrical blades, while the mCX uses undercambered blades. The mCX has a very low headspeed, while the nCP X has a much higher headspeed. Therefore, the nCP X requires more input power to the rotor just to hover & fly around, even though the birds weigh about the same.

That's actually a very good analogy and good explanation. Thanks!
