Subject: REFLECTOR: IVO Brush Modification

I've modified the IVO brushes using 12 gauge copper wire to contact the
hub rings.  A solenoid lightly presses the wires against the rings when
the pitch adjust switch is pressed.  The white wires going to the copper
wires serve as a spring to keep the wires from contacting the rings when
no pitch adjustment is being made.  I kept the original brushes in place
to keep the rings clean of dirt/oil and to act as a backup in case this
modification fails, and to supplement current transfer.  This is giving
me a very rapid pitch change (100 rpm/sec).
