An aircraft of the kind having a tail plane, and wings with ailerons which are substantially in line with the centre of gravity of the aircraft, comprising a main control, a planetary gearing including two coaxial shafts, a driving connection between each said shaft and a respective aileron, a gear fast with each said shaft, a planet carrier, a planet gear rotatable in said carrier and intermeshing said shaft gears, and a connection between said carrier and said main control which does not restrain rotation of said planet gear on its axis, whereby an operation of the main control merely tilts the axis of said planet gear to rotate the carrier about the axis of said shafts for moving the ailerons differentially, the rotative support of said planet gear permitting non‐differential movement of the ailerons in response to sudden changes of incidence of the air stream thereon without communicating a reaction force to said main control.
