My Slightly OTT DIY Motion Sim Rig - 3DOF + G-SEAT

Welcome to my build log of my slightly epic sim rig. It started out like most as something quite modest, and is now anything far from it – home to 6 (shortly 8, maybe 9) AC Servos for the motion platform, with an OSW wheel and more aluminium than you can shake a stick at. Through the process of building this rig I ended up on the SFX-100 core team handling documentation duties.

  • Version 4 – 2019-2020 (current) : Wanted the ultimate G-Seat; started building my own…
  • Version 3 – 2018-2019 : Discovered the SFX-100 system; built one, mounted to a simlab rig
  • Version 2 – 2016-2018 : Discovered OSW‘s built a MDF rig to hold it
  • Version 1 – Pre 2016 : G29 like everyone else, various contraptions to hold the wheel

My latest adventure in the descent into madness, is the addition of my own design G-Seat; which you can follow along in the section below.

This is the build/review log of everything on it. Video’s tell 2000 words so here you go :

I'm stubborn, I think this post will prove that. Following on from my previous post https://www.rowanhick.com/2020/01/25/delving-into-the-world-of-g-force-cueing I switched up my approach and went for a full blooded AC Servo, retaining…

Delving into the world of G-Force Cueing aka G-Seats

So lets get this out of the way; there's no way a motion simulator can actually simulate g-forces - what it can do however is "cue" forces. The more cues…
