    Hello, my name is Juan, I am Spanish and I live in Madrid,
    I have just finished my simulator thanks to the infinite help that you provide through your forums.
    My simulator is a very small and simple version, the room where I install it leaves me no other alternative but at the moment it works with Live For Speed, although my intention is that it works with Prepar3D, since I am a great fan of flight simulation since many years
    I want to show you the steps that I have followed for the construction and the materials and the tricks that I have had to invent to overcome all the obstacles that were presented to me on a mechanical and electrical level. IMG_20200615_190249.jpg

    As you can see the simulator I initially thought to install it in the structure of an office seat, I liked the idea, but once it was finished I discovered that the seat was too high and I could not reduce that distance from the ground so I had to change my mind and conceive a structure independent of the seat.

    Your updated version looks like it would be far more stable than the original.

    Basically the system consists of two wiper motors, a very robust cardan shaft, linear plastic potentiometers and quite rudimentary levers.

    In this other image you can see how the potentiometers engage the motor shaft in a simple and practical way

    My first serious problem was the short length of the motor shaft that I had to solve by gluing two washers to the lever and also deforming it so that it did not collide with the screws of the motor support

    I had to reinforce the anchors of the system due to its extreme weakness, duplicating supports and joint joints to give it some flexibility.
    Also I have installed some movable supports to rest the mechanical system when I do not use it.

    You may have noticed that the movements are very short at the moment, because I am starting to adjust the sensations that it transmits to the seat.
    This is the configuration of the 4 axis roll, pitch, surge and sawy
    Roll and appears I have them set to 20% smoothness

    The explanation of this 20% smoothness is for two reasons, set to 0%, the movements are extremely abrupt and the consumption of the motors shoots up logarithmically.
    This also occurs in any of the axes, but it is more noticeable in the lateral movements, surely due to the physical arrangement of the levers so close to the Cardan. detalle palancas.jpg

    THESE THREE POINTS are weak in my construction and I must improve them, I will have you informed when I have solved them, regards!

    Best to use something like an old car universal joint and mount it as close to the seat base as possible: https://www.xsimulator.net/community/faq/universal-joint-placement.108/

    The motor mounts, levers, rods and brackets are subject to high loads in our rigs and must be very rigid. I use 6mm thick plate for my levers and angle iron for motor mounts.

    Use heim or tie rod ends to connect rods to the levers and top brackets, with spacers if needed: https://www.xsimulator.net/community/faq/heim-rose-joint-conical-spacers.72/

    The simplest way to make a rod is to use the correct size threaded rod that will screw into your tie rods or heim joints, then sleeve over the top of it with 50mm square or round tubing, with large washers and lock nuts either end. That will prevent the threaded rod from flexing under load. Personally I used solid aluminum rod and tapped it either end for my rods and also a cross brace rod between the top of each gearbox, to make them really rigid. I use flexible couplings and aluminum brackets to mount and connect my pots to the gearboxes:
