So after a bit of a hiatus, I got the hydraulics from @ebinmaine for the C-141. After getting the belcrank out of the 520 center section, I cleaned it up, and installed it in the C-141. I then cleaned up the valve block, and after building a plate to mount it I semi temporarily installed it. It was a bit of a PITA to put in. While I was working on the valve bock and bell crank. I painted the hydraulic ram and installed it after the paint dried. The only thing left is to install the hard lines if possible, with some adapters. Or and the more likely route, some rubber lines to be able to snake the connections around the C-141’s slightly different mounting locations. And that’s where I am now.
