Well - - - I'll guess at your bl\ade bolt distance at about 100mm
That would make your rotor diameter 2 x 600 + 100 = 1300mm
1.3 x 39.37" = 51.2" = 4.265ft

For a tip speed of Mach 0.33 at sea level
1125x.33/4.27/pi = 1679 head speed for better efficiency.

And you trade off snappy control response.
