As the title conveniently trough a pop culture reference* suggest, we'll be talking about power.
Engine power that is. The question was, how much power does the used EMAX BL2210/25 engine consume. So a measuring contraption was built:
And after much fun fiddling with it, this is the result:
As expected, almost linear ratio between output power and consumption. Almost linear because the measurements themselves weren't perfect, since they needed to be interupted for the engine to cool off (no flight, no airflow).
