    Hi all, i joined this site some years ago when first looking to make a DIY motionplatform. Some time after that I backed YAW VR kickstarter and get one of their units.

    I owned it for two years now and I enjoy it a lot, with helo flights the most.
    I find it funny with jets and cars but I find it lack something and I even get sick with racing sims as movement didnt seem ok to my brain.

    Recently I got aware of severalapproaches of g-seat DIY projects some forum users had succesfully build and after read about them I ended pulling the trigger and will try to make my own g-seat inspired in their work..

    I will start with pneumatic g-seat for heave and sway ans my intention is to finish with a g-seat thet uses a motor for sway using padles, and pneumatic for heave and suge, adding belt tension to suge frontal acceleration.

    I,m completly noob on arduino but I will try to use smc3 code for my project, I had decided to use motors as I have 2 spares at home so I can invest my budget in other parts.

    I will list my parts and future purchases:

    Owned/Bought:
    -2 100w YAW VR motors with a optical encoder (I think I will have to skip it and go with a normal pot as I doubt they work with smc3 code)
    -3x Cytron md13s motor driver(As yaw motors use cytron md13s controllers I bought 3 of them).
    -Arduino uno r3
    -24v 360w power supply
    -4x pneumatic wedge
    -4 point harness
    -Several wood and mdf borads and ribbons for prototipe seat and paddles
    -Some spare V-Slot profiles (2020 2040) from other projects

    To buy:
    -4x pneumatic wedge
    -3x hinge (maybe more depending on final design)
    -1 motor.
    -Belt tensioner (have to investigate deeper on that topic)

    I uploaded smc3 to arduino and waiting my cutron boards to arrive to test them with my motors and a test board.
    First steps after that will be try if optical encoders on engine work with smc3. I doubt but worth try.
    Once I have done that I will start triing to add pneumatic wedges to sides and bottom for sway and heave effects.

    I will decide next steps after first tests.

    Mi intention is to make a g seat for 2dof seat mover without yaw axis or limited one but I have a 220 slip ring to add to it as a side project if this one is successful.

    Will update my progress here and post questions here or relevant thread as I come with them

    Did I understand you correctly that you want to disassemble your YawVR rig in order to use its motors for your new rig?

    I could imagine that - from a budget perspective - it would be better to sell your YawVR rig in one piece (assumed that it still works) and then spend some of the money for new, powerful motors.

    Sorry maybe I didnt explain it clearly.
    I want to mount the seat ON my yaw vr to use in conjunctiin with it.
    I have 2 spare motors because they overhead inside yaw and YAW VR sent me 2 replacements.
    Original motors work well under not so heavy loads and in worst case scenario I can buy 2 ebay similar ones.

    I intend to keep my yaw 1 at least till my yaw 2 comes. And probably will keep it anywais to use it with friends

    Ah, ok. I did not understand that these are spare motors.

    Post your idea sketches & Images of components including the Yaw VR for useful feedback.

    Sure will do! I only had installed smc3 by now. Once I have a bit more time I will take some pics on yaw internals and components. I still thinking about surge mechanism as probably first I try something with pneumatic wedges to keep weight as low as I can, but my original idea is to make paddles at some point even if its for YAW 2.
