Thank you sir. I tested one of the cylinders and it pulled 20lbs on the fish scale @ 10 bar with the smaller motor in the pics. I just installed an 1/8 scale brushless motor and oh my! I don't have the gauge on but it blew off the pressure line when I gave it 75% throttle. Had to have been around 30 bar. I am quite surprised as I am a newbie when it comes to a lathe and mill. I know how to 3d model and such so its kind of easy for me when its on paper but still surprised. I think if the housing were steel it would pump better. I can tell the aluminum housing wont last nearly as long as a steel one.
