Think of the effects of the ailerons on the wings if you are hovering with a tailwind…
With a headwind, if left wing drops, the aileron on the left drops, and lifts on the right… causing increased lift on the left… bringing the wing up…
But in a tailwind, the opposite applies…
Left aileron down with a tailwind, will cause the left wing to drop more!
Elevator down with tailwind will caused the nose to lift!
Reverse controls everywhere!
So unless you are nose into the wind… control surfaces may not cause the response you are wanting.
