Yes, but a Lipo cell is about 4.2 volts at full charge, so we have to expect 4.2 * 8 = 33.6 volts from 8s and this leads to 33.6 * 1.800 = 60.480 rpm, just above the motor limit

Bye.

Just remember two things about that; 1) the voltage will dip under load and 2) that 4.2v value drops pretty fast in less than a minute. Either way, you won't see those rpms for very long, if at all, unless you're running flat out right off the bat.
