I flew for a wounded warriors project on base a few weeks ago and almost put my 1/3 cub in the trees from 25mph gust.We had a usual 15 mph cross wind and got a big gust as I was making a low fly by. I had my wing turned down into the wind but when that gust hit it it almost rolled the cub all the way over. I had all ailerons and rudder turned into it. Just keep this in mind if you have a larger plane with low wing loading. If you exceed your crosswind component with these models you may take it back to kit form.
