Hi Dan
I had the same concerns, but the arm is smooth as silk, the swing is a bit jerky but it has a way to short stroke on the cylinder.  The small hyd lines and low flow pump are the key.

Thanks for posting the pics Hank. 
  
That's a pretty big valve unit.   
  
I have an old backhoe and a bucket truck.  The 
backhoe has manual operated valves and the bucket truck is electric from the 
bucket to the valves down on the truck.  It's far easier to move the 
backhoe right where I want it with the ability to feather the valve.   
I hadn't considered electrically operated valves 
because I thought the movements would be to jerky.   
How do you find operating the electric over 
hydraulic? 
  
Thanks, Dan H.
