1. A rotary variable differential transducer comprising:
a housing;
an armature shaft included within the housing;
an input shaft configured to mate with an airplane shaft, wherein the input shaft is independent from the armature shaft;
a segmented anti-backlash gear attached to the armature shaft;
a pinion gear shaft assembly configured to drive the segmented anti-backlash gear thereby creating a single stage gear reducer assembly; and
a plurality of stop pins included on each side of the segmented anti-backlash gear, wherein the plurality of stop pins configured to prevent the segmented anti-backlash gear from disengaging with the pinion gear shaft.
