 finishing up the hydraulic system, getting ready to test gear retract. Would
like to install pressure gauges in system:  does anyone know the
 upper limits for the internal high and low pressure switches?

[ from http://rob.com/lancair/2004.01/up.mov
I would guess up is ~750psi and

show about 500psi, but one can set it to
anything you want by turning the screw at the top
of the switch -Rob ]
