I am having a problem, I want to make an airfoil with 2 motions : rotating and pitching. So I made 2 kind of 6 DOF motion, the 1st motion is pitching for the small circle, and the 2nd motion is rotation for the big circle.

But the problem is when the small circle is successfully pitching (at maximum 20deg pitch angle), the small circle cannot push the big circle to rotate

When the small circle is given a relative motion to the big circle, and the big circle is given angular velocity, both of the circle are wrongly rotating

When I change the motion of small circle into rotation, the small circle is successfully rotating together with the big circle (of course without pitching motion)

How to make the small circle is pitching and rotating at the same time ?
I made the pitching motion is relative to the big circle rotation
