Wright Model E

The model E was fitted with a prototype autopilot that used a wind driven generator and pendulums to drive the wing warping controls.

The design was quickly eclipsed by a gyroscopic autopilot developed by Lawrence Sperry for the competing Curtiss Aeroplane Company.

[2] On 31 December 1913, Orville Wright demonstrated a Model E with an "automatic stabilizer" flying seven circuits around Huffman Prairie field with his hands above his head.

[3] The Model E demonstrations earned the Wright Brothers the 1913 Collier Trophy from Aero Club of America.

Albert Elton (1881–1975) purchased the sole Wright Model E for exhibition flights.
