Please read the question! what is the motor rated at in volts. I don't care about anything else I'm enquiring after the motor specs. VERY SIMPLE QUESTION NO YES OR NO JUST WHAT IS THE MOTOR RATED AT!
CAN I MAKE IT ANY SIMPLER? ???
It´s not that simple
Voltage ratings are pure "modellers stories".
A motor has 2 ways to die.
1) Mechanically by throwing magnets or parts of commutators or killing bearings, this is what´s limiting the voltage. You´ll never reach that point with 3S, you would probabaly need 5-6S and no load on the motor to kill it this way.
2) and much more likely by current. That´s why 99% of all motors die.
Unfortunately current is not directly depending to voltage (if you reduce prop diameter and pitch in the same way you increase the voltage, the current will not get bigger) but in fact if you use the same prop and double voltage you´ll need 8 times the current.
With the same prop as used on 6 cell NimH you will probably kill it on 3S.
