Irrelevant. Please show me the parameter in any law of physics that inputs the variable model or full size? Since some models are bigger than some of the smallest full size, please define the cross over point so that we know it is a model or a full size from the point of view of handling. Please describe the mechanism by which an aircraft knows it is a model or a full size so that it handles differently.

As I said in an earlier posts, there are model fliers who form a cult religion about the misuse of rudder and there is nothing in this universe that can show them otherwise.
