Servos can be used for point motor (or turnout) control, or for controlling semaphore signals. On my layout all of the points are operated by Servos.
These servo controllers require no programming, the servo angle or distance of travel is simply set with trimpots using a screwdriver and the direction can be reversed with a switch.
Servo 7 (2 Servos, 2 or 3 positions, with speed control)
Servos 7 will drive 2 Servos, each is set to 3 position. These are ideal for servos used driving 3 positions semaphore signals, and other animations. Each position is able to be finely adjusted for the correct position using the Trimpots (blue Square). The centre Trimpot is used to adjust the centre position. The speed of the servo travel is also adjusted using Trimpots.
These controllers can also be set for very reduced travel allowing very fine adjustment and slower servo speed for more realistic operation of semaphore signals that often have very small travel to move the signal arm.

The Price for Servos 7 is $60
Servos 8 (4 Servos, 2 positions)
The Servos 8 will drive 4 Servos, each is set to 2 position, these are ideal for servos used as point motors or other simple animations.
I also have a video showing how simple it is to setup.
For more information download these instructions.
The Price for Servos 8 is only $60 (this is $15 per servo)
Servos 8g Gates (4 Servos, 2 positions)
The Servos 8G will drive 4 Servos, each is set to 2 position, these are controlled with a single input, especially designed for crossing gates.
I also have a video showing how simple it is to setup.
For more information download these instructions.
The Price for the Servos 8G is $60
Servos 9 (3 Servos, 2 positions, with speed control)
The Servos 9 will drive 3 Servos, each is set to 2 position. These are ideal for servos used driving semaphore signals, other animations. Each position is able to be finely adjusted for the correct position. These controllers also drive the servo slower for more realistic operation.

Servo is attached to the Mounting assembly
With the Gate Servo mount and the Servo Connector for vertical wire it is now easier to attached your servo (below the baseboard) to the gate (on your layout). With Adjustment to align the activating wire and also the rotation of the wire to achieve the desired result.
Servo Mount Gate
SMG $8ea
Servo connector for vertical wire
This a a small 3D printed part to connect to the top of your servo arm to attach a vertical wire. This is for those using the Servo 8G to operate crossing gates.
This Connector screws onto the servo horn with the two M2 bolts provided. Brass wire is glued into the hole at the top, this can be drilled out for the size of wire used.
The brass wire in the top is then connected with your gate mechanism.
Servo Connector for Gates, SCG Cost $1 ea with screws
