And another foot note.  One of the main advantages of this type of gear is when the gear is fully extended and fully retracted there is no movement in the leg.  The screw jack winds the gear tight against the stops and takes all the play out.  The disadvantage is the speed it takes to raise and lower the gear and another consideration is g load.  if the aircraft is pulling significant gs the gear will stall going up... one thing to watch for.  <div>
