    Hi all,
    I'm quite new in this world and now, after reading a lots of threads, I'm starting to build my personal 2dof + traction loss.

    Choice of design:

    A draft of my design is this:

    Initially I'll work only on 2dof and then I'll upgrade it with the traction loss movement. I'll put the motors from pitch and roll in front of my sim

    Choice of motors:
    I have bought two 24V 55rpm motors from ebay and I have modified they to get a completely isolation from each other.

    Choice of power supply:
    I have chosen a simple and economic power supply from ebay. In my case 24V/30 A

    I use a 10k single-turn potentiometer for motor position feedback connected with two 3d printed gears for motor reduction.

    Motor driver board:
    I'll use a custom driver board designed only to control dynamic simulators, with 2 channel and Arduino Uno as controller

    Construction of the structure:
    I have just complete my rough structure. I'll start with tests and regulations as soon as possible.

    Testing phase:
    I'm starting with first tests of my sim! Initially without levers to avoid accidents and damage :D

    Hi Diego, I did the same thing for the front bearing for traction loss - kept it simple! I was going to use similar motors to what I am seeing in your build but decided against it and ordered bigger 50:1 motors. Once you get the weight of the seat, and the weight of yourself etc on the motors post a test video if you can. A lot of us would like to see how those motors take the additional weight. My rig is set up differently but I am planning on building a compact rig some day.:)

    @diegocom has not been around for about a year, so it could be a while before you get a response.

    Well, that's the way it goes I guess. Either way, I will answer the question as It applies to my rig.
    Ferslash, I use the IBT-2 motor controllers. I have three and a 6 inch computer fan blowing on them when the Rig is turned on. Hope that helps. H2go
