If I were to scale a helicopter rotor from 1,1,1 to 2,2,2 the game appears to account for the change in rotor diameter and the blades become more powerful; is that the only variable that is affected?

I would like to scale-up a helicopter of mine for use in VR and I have certain rotorperfscalars right where I want them. I would like to know how scale affects performance so I can account for it without redoing my rotorperfscalars.

Thanks in advance!
