I've been developing a linear servo for rudder actuation.
-Real 576 ozf moving (holding power will break airframes) at 4.5A stall on 2 cell LiPo (20mA at idle, 300mA at minimal load(swinging the rudder at the wind))
-0.08 sec/60 deg.
-No less than 12 ball bearings.
-Composite frames for rigidity.
-Active gear wear compensation.
-Non contact absolute position feedback, NO POTS.
-The position information is updated more than 1000 times a second, resolution of 0.001 inches.
-Return to center is measured to 10 thou (that's the thickness of two sheets of notebook paper).
I'm seeing if there is any real interest. I have a short video of the creature moving under it's own steam

Thanks in advance.
