Default BP21 info needed for Motocalc, & RPM/prop data

Hi all, I need your help please,

1) What are some of the Prop/RPM data on the BP21 motor using a 3 cell Lipoly?

2) what are the 3 constants for the BP21 motor so I can plug them into MOTOCALC, they are rev/volt, resistance, Amp (without load).

Your answer to these 2 specific questions will be greatly appreciated.

Thank you all in advance,

Gryphon

Thanks GWR, but I'm afraid it does not help me.
I have seen that page before, and the only single piece of info on there is the KV of 1750.

I needed the other 2 constants and also some RPM prop combo.
