19" x 4" piece of aluminium with the sharp corners knocked 
off. The only HiTech bit being its origin :-) Originally from  
Data General Eclipses or Nova computers (19" rack mount). 
Just so much better getting some blade deeper into the water 
at a better aspect ratio. I usually do have a little bit of 
balance because the lower end is just forward of the hinge 
line. Because the blade goes deeper before lifting when the 
tip hits something, my stanmdard production lifting/tilting 
rudder assembly is better. I also shape the blades a bit better 
though a foil is the proper way to go.
