I'll take that as a compliment!

Let's keep our fingers crossed that the rules for the other winds will be updated soon.

What would be a range for in milli-Ohms for motors? Like 17.5 - 21.5T specifically. I'm guessing as long as the meter will read from 0-100 milli-Ohms with good accuracy, then it would work well.

ROAR currently specifies resistance only for 25.5 motors (101 milliohms at 25C). Reasonable minimum resistances for the other motors would be:

10.5T: 15.5 milliohms at 25C

13.5T: 25.0 milliohms at 25C

17.5T: 42 milliohms at 25C

21.5T: 64.9 milliohms at 25C

Is that a single pole (A) or two poles (A+B)?

My apologies, I should have stated the conditions. This is the resistance measured between any two stator terminals-- A to B, A to C, or B to C. No motor disassembly is required, and in most cases one does not even need to disconnect the motor from the ESC (but the ESC must be disconnected from the battery).

All times are GMT -7. It is currently 12:50 PM.
