It may be necessary to consider rpm drop of the motor under a load in the calculations.
RPM drop of the motor (per amp) is the unloaded kv x the resistance. Rpm drop will always be the same no matter what voltage. Ex. a 5000 kv motor with .006 ohms will drop by 30 rpm per amp. So if you're running it at 7 volts and it's drawing 20 amps, it will have 34400 rpm. At 1 volt and 20 amps, it will have 4400 rpm.
