It depends on the the maneuvers etc. IF you have a 8411 on the rudder and only use it for taking off or a knife edge once in awhile then no it will take for ever to get any type of slop at all. On the other hand if you have the 8411 on your patty and use the rudder alot it is still not going to wear out because it has more than enough power for the size rudder surface you have. [8D]
