Not so, as my research so far shows. Not all servos have internal stops and even continous operation is possible (See http://www.kronosrobotics.com/an116/GAN116_3003.htm)

Extending the arc of operation by internal mods involving a couple of resistors is described here http://www.margammodelboats.co.uk/images/BMYC.pdf. on page 8.

Also depicted on page 8 is a commercially available (in the USA) servo stretcher and it's that unit's function that I am trying to replicate in a home brew. (Model-speak for keeping the costs down). It does not look especially complicated which is why I hoped somebody could come up with a circuit.
