Pic 6 shows the steering servo pushrod supported by the slot so that the nosewheel centres during retraction. The siding horn is a nylon strip aileron horn and the pushrod fastens to that with a screw-up servo connector. The vertical wire rod is soldered to the Robart steel tiller arm along with a brass wheel collet for extra support. I’ve programmed the Tx to inhibit the nose steering channel when the retract switch is selected “up” and this automagically centres the nose steering servo too. Thus the nose steering servo doesn’t move with rudder when the noseleg is retracted.
