Their first kite included a front surface for pitch control and they adopted this configuration for their first Flyer. They were suspicious of the aft tail because Otto Lilienthal had been killed in a glider with one. The Wrights realised that a foreplane would tend to destabilise an aeroplane but expected it to be … WebThe phase difference between the front and rear wings is sufficient for the fore- and hindwings to interact hydrodynamically and to generate more lift .
