It's the first time I've watched your video in operation. Seems like every time you get to the end of the cylinder stroke, engine stalls. I'm I correct in this? So, at minimum, doesn't that indicate a pressure relief problem? That' got to be tiring to use like that.
The inline flow control I posted is to control the Boom drop only and should be mounted on that cylinder. The Pressure compensator flow control https://encrypted-tbn0.gstatic.com/s...Of_00&usqp=CAc should mounted ahead of the FEL stack to control the overall speed. The relief valve in the FEL stack should be reduced until the engine no longer stalls.
