I don't think an arf or a kit will know when it's windy, the wind only effects the pilot Fly the plane, don't let the plane fly you. Those words are what my instuctor told me everyday. Iflew my GP Easy Sport in a gale, 3/4 throttle landings are fun! Only mishap was breaking a prop, on the ground while tunring to line up on the runway. Wind flipped on it's side.
