G'day Jack,
If you look at the piccie mate, the hole at the top of the rudder blade is to take a cord that runs to a clam cleat near the cockpit.
Simple matter to raise the rudder when needed by simply pulling the cord and jamming it in the cleat to hold it up. (where it will be most of the time)
When needed, just unjam the cord from the cleat and the rudder will drop into position.
I like things simple
