converting from fergilli rams to air . but no power

[Acadieman]

Please take this with a grain of salt as I have never worked with RC pneumatics before.

Unlike a hydraulic system, most air systems have a tank that the pump will pressurize. The attachements are ran off the tank to assure there's suffiecient flow and pressure. One of the reasons for this is air is compressable.

I would almost think a tank would be needed.
With that being said, I'm awaiting replies from others as well.

You will struggle if you are using the hobbyking rams because they are so small, diameter of maybe 4mm? not sure how much pressure you compressor makes? like acadieman said you would probably need a tank for it to work better. Here is how it can be done hydraulic using similar valves to the ones you have, wont be very precise though http://umstech.in/admin/Uploads/pdt_...012kg%2003.pdf
