One thing that had a problem with doing the harrier and elevator is wing rock. I read this forum and find the best way to fix it is to have spoileron mixing and balance my plane laterly. I started 3D on my UCD 60 and begun to fix it with laterally balancing it. I did that and it still did it. Next I tried spoileron mixing and added about and it still did it so I added more and more. The next thing that happened is that my UCD went right in. I fixed it and said the heck with it and started practicing hovering for the rest of the summer. Next year I got my UCD 60 up and running along with the ef yak 54 which people said Did not wing rock. What did my yak do, It wing rocked. I was looking at Cris Myers 3d movie and noticed that in his video he had some wing rock with his yak and saw him try to correct it with the ailerons. After that I noticed that after about a couple days I could harrier, not only with the the yak but the UCD with no spoileron mixing and wit ha poor lateral balance. Another thing I noticed that when I went with or against the wind the plane bearly wing rock rocked. When I went cross wind the plane wing rocked the most, but I had to give aileron toward the wind which would be opposite when I turned around and went the other way. I can now confidently say I can do 3D and mean it. Not just do a harrier at 10 degrees or T/R for 2 seconds, but harrier at a 45 and T/R down on the Deck.

What I am asking with that long story is do we really know what wing rock is? Why is stalling the wing more (spoilerons) help? Why is there more or less wing rock relative to direction of the plane to the wind. Or do we not know what we are talking about and just taking some Idiot's explanation and adapting it as our own.
