General rule on prop diameter vs pitch to maintain current?
As I have no test equipment to check amp draw, is there a general rule for maintaining the same amp draw? As a rough example if I am running a 12x6 prop on a geared brushless setup, would a 11x8 and a 13x4.7 both draw similar current, or are there too many variables for such a simple theory?

A more accurate equation is Dia to the power of 4 times pitch.
9 X8 : 9X9X9X9X8= 52,488

If you've got a tach, just make sure your new prop rpm is at least the same or higher than the old prop rpm. If its exactly the same, your amps are exactly the same.
