Does the pulse width need to vary beyond the range produced by a typical hobby receiver to get the full 270 degree rotation?

Yes,you're right! Generally speaking, the output pulse width of the remote control is in the range of 1000-2000,so the displayed angle is 135 degrees;To get the full 270 degrees rotation, the output pulse width should be 500-2500. :)
