We are currently working on a device which should easily and accurately determine the wind of a given brushless motor
Steve, Can you please PM me when you get the tester sorted.
One of the issues we have come across down under, is the inductance tests don't always work. We ran a major meeting using the Novak 13.5's in the middle of Summer and had issues with wildly varying readings. The Novak test results are on only 20 motors tested, not enough as far as I am concerned as this would not even rate for a poll.
I have heard rumours that other brushless motor manufactures are coming out with motor testers, but still waiting
Maybe an optical tacho, with a fixed voltage power supply to keep it all consistant, then we could work of the RPM/V rules.
