Could you not just use a small aero prop and an eagltree with BL rpm sensor? spin it up and divide the RPM by the number of volts to get KV? then you know what wind it is and can look the rest of the info up on the feiagio website.

I have an eagletree, BL rpm sensor, 5mm prop adaptor and small props if some one wants to sent me a motor to test, but I'm sure someone in the USA also has the same equipment and that would reduce the postage costs at each end. unless someone in the UK has the motor?
