The double tiller arm is mounted directly to the retract body.
On the strut pin there is a collar with a steel pin that engages on the tiller arm when the gear is in open position.
This allows you to fix the steering servo wherever you want, you just need to connect it to the tiller arm with pull-pull wires or a stiff linkage.
When the leg is closed there is a spring wire that keeps the strut centered.
Also the tiller arm is centered by electronics so that when you open the gear the pin is always centered on the tiller arm.
Only after the opening cycle is complete the electronics will send the servo to the trimmed position.
The main advantage is that the weight of the moving mass is lighter because the servo is in a fixed position and does not follow the gear strut.
