						 The Yale does not have a hydraulic system.  The handle is a crank handle (knob) that winds them down.  All of the Yales that survived had been converted to a wireless trainer with no rear cockpit controls.  The flap handle was replaced by a simple bushing.  Unfortunately, my little project is also missing the bracket that holds the bearing, which is a cast piece.  I can have them milled but before I do so, thought I would see if someone's already done it.  I'll snap a picture of my front cockpit (it is installed) but it will be a while before I can send it to you.
