Hi Guy's
        I had a hard time believing the current draw for the pump so I brought home my good "Fluke" multimeter from work. The one I used last night was a cheap Digital meter from "Canadian Tire". I seldom use this one, so I'm not familiar with it but since it is very similar in outward appearance to my "Fluke 87" I assumed the same functions would apply. They don't.

 OK,OK, enough excuses, now for the real current draw.

  • continuous current draw - 4.3 amps
  • max inrush current draw at 100mS - 6.8 amps
  • max inrush current draw at 250uS - 13 amps
  • 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.
