Claim 10:
11. An aerial vehicle comprising:
a fuselage;
a wing including a rear spar;
a control surface actuation system mounted on the wing comprising:
an actuator support fitting mounted on the rear spar;
a rotary actuator mounted on the actuator support fitting and having opposing output shaft ends, the rotary actuator defining an actuator axis;
first and second torque tubes coupled via actuator universal joints to the opposing output shaft ends and extending substantially obliquely relative to the opposing output shaft ends;
first and second pivot mountings mounted on the rear spar on opposing sides of the rotary actuator;
a control surface; and
first and second pivot joints coupled to a hinged end of the control surface and respectively connected to the first and second pivot mountings, each joint being coupled to one of the first and second torque tubes via control surface universal joints, such that rotation of the first and second torque tubes causes rotation of the control surface relative to a hinge axis.
