I was just wondering if anyone had insights on how to optimize the lifting power of rotors/maximum speed. Does torque decrease as rotors get closer to their maximum RPM? To optimize lifting power (for a given radius of the blade disc), do we want high RPM, or low RPM and lots of wing area? I was also wondering how lifting power is relative to G and air pressure. On Eve, the atmosphere is much thicker, so its like operating a rotor with 5x the surface area on Kerbin. The gravity is
