The 150/152 rudder stops on the rudder horn was in response to loss of control issues during training specifically spin training
The original stops were much smaller and could jump over the adjustment stop resulting in jammed rudder and several deaths Regarding stress on cables as a former 152 owner I put enough stress on the rudder stop once In a cross wind landing I should not have attempted that I bent a pulley bracket The A&P stated the cable was fine and just repaired the bracket Looking back on it now maybe he did not want to rerun the rudder That was my experience Gary
