That brings up another question; How much pump pressure is being used in turbine model aircraft and are you using pressure regulators?

Sure appreciate any feedback you folks will provide.


We mostly think of fuel flow and not fuel pressure. Our pumps only operate with as much voltage/speed as necessary to run the turbine as commanded by the ECU in response to throttle position. It is purely suction on the supply side and positive pressure from the pump to the turbine. I have never seen a pressure value and we don't use pressure regluators.

FYI, our supply lines are generally in the 6mm range and pressure side lines are 4mm. The max flow in our largest turbines is about 24ozs /minute.
