The Dorsal in A cross wind???? Well, does the term weather vane mean anything to you?? A Kaos is so long that it weather vanes in A light breeze. Add that Dorsal and when I fly in A heavy cross wind the plane comes in looking at me. So, the Dorsal is no help at all in A cross wind and if you aren't ready for it then it's going to bite you very hard right where it hurts the most!! What it does is add the side lift that is required to do A nice knife edge. To that end it is perfect and works very well. This and one other little plane are almost always with me so they get A lot of air time and they both tend to be the most fun planes I have to fly. Bigger fly's better but my 60 size get flown the most!!! At A couple of fields here if you don't fly in A cross wind then you would never fly at all. Vegas is A very windy area and the local fields wern't designed by RC pilots so you take what you can get!! We do have some very nice looking women in the area though!!![8D]
