You said the key word "wind break". While above the cornfield, you held the sticks trimmed for your approach based on the wind up there. Then as you dropped below and entered the wind protected area, your air speed dropped radically making it mushy in the turbulence of the protected area. On top of that the aileron/rudder were in in the wrong spot once you were got there as you found out. And what should have been the final nail, ya dumb thumb it off the deck yet pulled it off .. You lucky so and so Yeah most of us have been there, but not always that lucky.,,or was it skill

Next time a bit more air speed as you descend into those conditions.
