Of course it will make the airplane yaw but that is where your logic ends. The yaw force applied equals the force applied by the cross wind thus end result is an airplane fly's a strait path while being rotated a few degrees nose into the wind. This is possible with a model the exhibits pure yaw control. Again we are talking models so this is happening for a few seconds at a time your comments about hours long flights are just nonsense. Let's face it, we both have to much invested at this point to see each others view. My vote is to just move along, we each fly our airplanes the way we want and we all stay happy.
