only if you strip one servo and it flops, in most failures they lock and with the servo locked the fulcrum point is just half with one servo operating, if you don't believe it just unplug one servo from the RX and give it a go, it'll cut the deflection by half. for every 1" of servo movement with one locked in a fixed position, the push rod will only move 1/2" but that servo will have twice the torque, it's called a 'Simple Machine' or in laymen terms a leaver
