Will it clearly identify if the stator has had a turn removed or if a 15.5T stator has been used in place of a 17.5T.
Why these are still using just inductance is retarded, though I don't see any numbers published next to approved motors either. Inductance is easily cheated on even the most accurate meters, as numerous things can influence it...resistance does not really have those issues, but the correct meters to measure it are not as cheap as a decent LCR...

The inductance has only been specified for recently approved motors if you scroll down the list you will see them.
How is inductance easily cheated?
Resistance even with an accurate meter can provide the same result with a different number of turns. IE what if I rewind a 17.5T stator with slightly thinner wire but I use less turns and the resistance measurement is identical to the original.
Motor would produce more rpm and more power in the mid to upper rpm range but resistance measurement is the same.
Inductance on the other hand would be different.

My current lipos measure 1.4mohm and 1.6mohm per cell. I have used 3-4mohm lipos previously and I didn't notice a difference in temps.
