I get this very often in WWI planes, mainly the Camel, due to my high use of the rudder during maneuvers to keep the plane straight. The Extreme 3D Pro that I use for the rudder does spike on the Y axis, but because I don't use that axis, it doesn't lock my controls. My Attack 3 works fine though, with no spiking. I move that this wish become a wish to remove the "Don't move your controls so rapidly" lockup to be removed from WWI planes. I mean, how are you going to stick stir in a plane made from canvas and wood?
