John has been talking about 0.333 of rotor diameter in case of 3000rpm, but
i cut 0.4 already and plan to go even further - just want to see what
would happen next : D

you are talkin about loading on motor at full speed, but i`ve asked about
the moment when motor is trying to start, coz i "think" that there is
_zero_ load at full speed - am i wrong?
