[QUOTE="jeallen01, post: 1142002, member: 176704"] All of those component failures point to basic design/testing errors (&/or "cost cutting"!) in those STAB motors.:rolleyes: Anything with driven moving parts such as motors should be tested in "locked" conditions to see if any components overheat &/or fail, and then the corrective action should be taken[I][B] by the manufacturers!
