well i broke my servo case today, dont know if its from the minor flex in the way it was mounted or if it was from the fixed object i hit, but i will using a plate on the bottem of servo for a flat surface secured thru the bottem of the chassis and screwed into axial stand-offs and then mounting the servo to them on the top side, should be more secure and rigid
