Look forward to your review of our system. We are constantly evolving and so please go easy on us. lol Takes a lot of time and energy to create a market facing product... Applaud anyone who has tried or is doing this now in volume. Not easy. :-| Ultimately competition and criticism is good. Evolving.Howdy ! You guys have seen me here - lurking, asking for extensive detail, and pressure-testing the Sigma team - for well over a year now. My first motion system was the Dbox 1.5” gen 3 system. I just upgraded to the Sigma DK6. It was the right time and the planets aligned (rally has been my genre of choice for a while, the Sigma HW has evolved, their software is more refined, and there is more comprehensive game support).
I can’t review the system yet because I haven’t owned it long enough to do a legit review. But I can say that this is one big, beefy, solid system. I have a pretty heavy rig (over 300lbs), and I am a heavier guy. That meant that in addition to making sure my 80-20 rig (thanks advanced sim racing!) was super-reinforced, I needed to make sure that any motion system I purchased could handle at least as much weight and stress as the dbox system. So far it’s a non-issue, and I am confident in what I am seeing and feeling. In fact, the increase in motion agility is putting the Kirkey metal seat that my Gseat is made of to the test. I need to break out the lubricant for the squeaks at the assembly points! Then again, maybe I will leave it be as those squeaks have an organic element to them, as if I were in a real car .
When I do comment, I will comment not only on how the motion system itself is working, but also how well it integrates with other systems to create a holistic experience (this includes gseat and belt, wind, and soundtrack based haptics).
Regarding the heft of the system. From the very beginning we knew that it didn't matter how good your telemetry is and how responsive your motors or algorithms are if the small nuances of motion are dampened or absorbed by the components holding the motion system to the rig. We actually tried various materials in R&D including, brass (these looked phenomenal) and Teflon/Delrin/PTFE leadscrews and various cups and brackets/foot designs.
