Thanks all for the info and comments. I don't think its a lateral balance issue as I have loaded one wing and then the other with weight without any real effect with respect to this issue. For whatever reason, its much more difficult to creat this effect with outside pushes!? I have seen this on so many planes that I don't believe it is just a wing warp or mismatched incidence problem. As has been pointed out ... for larger planes not an issue - so I understand comments re wing loading. Has anybody tried inboard stall strips or similar approach .. or is that just way too honky?

Thanks
