Can't you just reverse the direction of the servo? If the arms are, say, towards the rear of the fuselage like mine is can't you reverse the servo so that the arm is facing towards the front of the fuselage, so that the pushrod connections are on the opposite side of the servo arm? I, too, can not see why you don't wanna use the feature on your radio. I have to reverse some of my servos on my LT-40 (elevator, rudder and throttle) because of how the plans instructed me to install the servos, but I will do it the easy way with the radio feature (as soon as I learn how to set the radio up for model 1, and then save the settings)
