OK,OK, enough excuses, now for the real current draw. a.. continuous current draw - 4.3 amps b.. max inrush current draw at 100mS - 6.8 amps c.. max inrush current draw at 250uS - 13 amps d.. continuous current draw at minimum controlled flow - .2 amps The max inrush current is not really relevant to our concerns, but there it is for those that care. This higher current flow is still well within acceptable limits for my needs, and I expect that while in cruise flight, the controller will be reducing pump speed and current draw. S.

continuous current draw - 4.3 = amps
max inrush current draw at = 100mS - 6.8=20 amps
