"I'm having trouble visualizing a linear relationship between voltage and power as you describe. I'll continue to think about this."
It takes about 1.5 V just to get an RC brush type motor turning. A straight line develops from this point and increases. This is a graph out of an RC book that I wrote. It is no longer available. I have not tested brushless motors this way but you can see the problems adapting strict theory to RC motors. Click the graph then click once more for a larger view of the graph.
