He's using a Digital to Synchro converter.  He managed to find some
surplus.  This allows him to "correctly" drive his real aircraft
instruments.  The cheapest D->S chip I've found is $955 in single
quantities.

Cool!  Glad to hear it!

Actually, resolvers have a huge amount of torque.  I think you're thinking
of air-core motors.  They work on a similar principle, but product almost
no torque.
