You got it working good job
Swing is pretty slow, what rpm did you use there?
Hydraulic speed seems ok... to help preserve battery time, radio mix valves to cylinder chs so pump motor slows to 20% idle speedwith no stick no movement. With these rather large outrunner brushless motors on the hyd pump, there's certain amount of stall amperage to start them, so always have pump motor turning so you don't cook your esc.
The stick cyl, at the back of cyl, was the pin mount machined into the boom? ...if you could your stick cyl back about an inch, get your stick to fully stretch out.
It's looking good, keep at it.
