1. A drive mechanism, comprising:
an input drive that receives rotational input about a drive axis;
an input drive hole provided in the input drive;
a control surface;
a control surface shaft extending from the control surface; and
a control arm extending from the input drive hole;
wherein rotation of the input drive about the drive axis is transmitted through the control arm to rotate the control surface shaft about a control surface shaft axis; and
wherein the control arm is directly mechanically coupled to the control surface shaft.
