    I have been spinning it using a rubber cone mounted in a cordless drill.

    How many RPM do you suppose that drill spins? What ever it is it will not spin it fast enough to get a correct reading. Use compressed air.

    Use one or more large leaf blowers to drive it. From the prop I'd guess it spins maybe 3000 rpm at max output. It has to be a really draggy thing though.

    Thanks for that, I'll give it a whirl with some air. I think it's OK because by manually closing the voltage regulator contacts I could get a reading albeit a small one.
