Well those are D'Arsennault(sp?) movements and you could probably drive 
them using the PWM output on the Arduino.  It would be impractical (not to 
mention impossible for thing like flags - no room!) to convert such things 
to air-core.  I seriously doubt Matt would consider such a path when it's 
painfully obvious that they're not synchros.
