I'm new to this, but got so far as matching up my motor and prop and doing a full throttle bench test to test the Amp draw. I got 15A at full throttle which is within the generally recommended ~80% max Amp rating, though only just (17A in this case).
I was wondering what the difference is between the bench test and actual flying measurement (I don't have any kind of telemetry) in terms of the Amp draw. Will the Amp measurement be lower because on a bench the prop is pushing stationary air vs at steady speed when flying there would be less stress on the motor? Or, due to the already moving air (relative to the plane), would the motor be able to spin faster and consequently pull more Amps?
Do I need to allow for the difference in calculating the draw when I set up the plane? I don't want to burn anything up.
It's times like these I wish I'd concentrated more in physics lessons.
Confused.
