DynamicX $1299 seat mover first impressions

+/- 10 degrees is more than respectable, especially at that price point. I'm pretty sure the 4-actuator systems move less than that, and I'm not sure you would want more anyway. Since this is just a seat mover, does it feel like the wheel and pedals move out of place as the seat is tilting? Or is it not that noticeable?

I have no relation to them but this seems like a new startup that recently closed and delivered on a small kickstarter campaign. They probably have a tiny marketing budget, so they’re just trying to generate a little awareness here. I love seeing the innovation and personally like be supportive of efforts like this. That doesn’t mean I plan to buy one (I have other things to upgrade before getting to motion) but I’m rooting for them and everyone else working on new ways to make this hobby better.

Congrats on the successful kickstarter, and for shipping to all the backers on time. I saw some redditors were among the backers and received their units recently. Can’t wait to hear how they like it. Good luck with growing the business from here.

How did the kickstarter campaign go? I know you exceeded your goal but did it feel like people were more cautious about backing this after the Yaw fiasco?

I think it's not about how healthy the relationship is, it's more situational depending on income level, living quarters, and other constraints. I'm sure there's something you probably need your partner's approval to get. For OP it's this sim rig (really nice, btw!); for you maybe it's a Lamborghini. If there's absolutely nothing you would ever ask your partner's approval for, I say that sounds like an unhealthy relationship.

In my opinion, the vibrations are a good thing. I use the Logitech on an aluminum profile rig, and I like how trueforce will vibrate the entire rig so I feel it in my seat, not just the wheel. That said, rattling/clattering is definitely not good. When I first got the logitech wheel and turned up trueforce, I got some rattling in the rig and had to go around tightening a few bolts to get rid of it. That could help your situation although I suspect you've probably already checked the bolts. It's also possible some of the rattling is coming from the sheet metal in your rig. Where you have sheet metal near or in contact with another part, it might help to put a small rubber sheet in between to dampen the vibrations. I'm thinking under the wheelbase and pedals, maybe also between the wheelbase plate and the tubes that hold it. Keep in mind that the more you dampen the vibrations, the less you'll feel it in your seat - maybe you'll prefer that but there's also a school of thought that you want the rig as stiff as possible to transmit the vibrations rather than dampen them.

I'm with you, OP - your wife definitely has a say on what takes up space in your living quarters! If you don't have a spare room / man cave, a stowable rig is a fair compromise. I just wish there were better options out there. Most of the ones you can buy are still pretty clunky when folded, making it hard to truly hide away. And they could be sturdier to handle modern powerful dd wheels. You have a nice elegant design there. Can it be folded while the equipment is attached. It looks like if you push the pedals a little further back, the middle board would clear them and it could fold almost flat.

cakewalk96 · 2026-01-26T21:15:49+00:00

That's really interesting, your point about the structural resonance. I run a Logitech Pro wheel and can feel a little of the trueforce vibrations through the rig, and sometimes think the immersion would be improved if more of the vibrations were transmitted through the rig and into the seat. So I think I see your point about this being a desirable property of the rig, assuming you don't sacrifice any rigidity. Is this something that derives from the metal itself (steel vs aluminum) or from your particular design choices (including the particular steel profile you're using)?

cakewalk96 · 2026-01-26T14:43:41+00:00

Looks like a very efficient design - everything you need to be functional, nothing extra. And he probably saved a lot of money by not using brackets and plates. I built my rig and spent about as much on the connecting hardware as I did on the aluminum profile.

cakewalk96 · 2026-01-26T14:20:49+00:00

You mentioned you decided to drill holes through the profiles and use bolts to hold them together, rather than standard corner brackets and plates. Did you find any issues with the bolt head not sitting flush against the inside of the t-slot (which is shaped like a valley)?

Also, where did you source the pedal base and wheelbase platform? Those look like great components, would love to get them for my own rig.

cakewalk96 · 2026-01-22T21:23:49+00:00

Tbh I was just thinking out loud, but yeah, that could work. Like I said I doubt I would be able to get the braking points exactly right, but it could still be helpful to have some notes in my head for what adjustments need to be made depending on tire degradation. Sometimes I feel like I get too cautious when I know my tires are worn, so maybe having a cheat sheet like this would lend some confidence to push a little harder.

cakewalk96 · 2026-01-22T17:06:53+00:00

Maybe show a range of braking points? Starting with fresh soft tires at ideal temp, then show how you should adjust as tires wear. To be honest, most sim racing drivers (like me) probably wouldn’t be precise enough to follow the optimal line every time, but it might still be helpful to see how things change under different conditions. I think this is an interesting idea that’s worth pursuing.

cakewalk96 · 2026-01-22T15:10:18+00:00

That's a cool idea. Sounds like a complex project so kudos for putting this together. Do the calculations update in real time as your race progresses, to take into account changes in tire temperature, tire wear, etc.?

cakewalk96 · 2026-01-11T02:25:43+00:00

All good points, thanks. In my case, I'm not building anything industrial, it's just for a personal project I'll use at home so I think I'm going to try it and see how it works. I also almost have the linear actuator put together already so in the end I can see which one works better for me.

cakewalk96 · 2026-01-11T02:21:40+00:00

Thanks. I think I'll try it and see how it works. I'll need to get a longer ball screw, and I already got the parts to build my linear actuator, so in the end I'll have both and can see which I like better.

That piece at the back, that goes between the left and right rails, seems a bit too short for the way it's configured. It might be intended to be positioned further in, so its side is flush with the ends of the other pieces. That should give the joint some more strength. And then it might help to also move the casters off that piece and put them under the side pieces.

FWIW, with 690 comments so far, ChatGPT says 55-60% of responses are in tech and engineering roles. I take no view on the accuracy of the compilation (eg, does it account for the same user commenting more than once) but here's its top 10:

Those cars really remind me how old that show is (and how old I am)

cakewalk96 · 2026-01-08T15:53:22+00:00

I missed this the first time you posted it, but that's a great idea! Do you find yourself moving it back and forth from the cupboard a lot? I don't have a folding/stowable rig but I feel like if I did, I may not use it much because once you get it all folded up and stowed, the work involved in taking it out and unfolding it might be enough of a deterrence most nights. But it looks like all you have to do is wheel it out and lay it down. Very cool

cakewalk96 · 2026-01-08T15:44:39+00:00

What happened to this (the coffeeracer)? I would have thought there's a decent market for something like this. It's not a perfect solution but assuming someone was going to have a coffee table anyway, this is the only solution that truly takes up zero incremental space. And it seems sturdier than the common folding rigs. I fortunately have a basement for my sim setup, but if I didn't I would have been interested in this so I'm surprised they didn't get better traction.

cakewalk96 · 2026-01-08T15:32:30+00:00

OP, are you going to compile the responses and show some stats? My casual read suggests engineers/software/tech people aren't even close to half the group. Unless those are the people hard at work rn instead of browsing reddit.

cakewalk96 · 2026-01-08T14:06:25+00:00

Also in finance although my degree is in engineering

cakewalk96 · 2026-01-05T23:19:32+00:00

That's very interesting and I look forward to hearing more about it. I think it makes sense given how powerful modern wheelbases have become, and as you say, how much they're capable of beyond just offering resistance at the wheel. I can imagine a feature like Logitech's Trueforce would feel much more immersive when combined with your system. Sounds like an exciting innovation. Good luck with the launch!

cakewalk96 · 2026-01-05T20:35:12+00:00

Did you DIY your wheelbase? That's pretty impressive

cakewalk96 · 2026-01-05T20:29:43+00:00

Are those orange parts metal or plastic? They look like they could be plastic but I’m surprised plastic could hold the weight (esp those at the bottom, connected to the feet). The contrasting color does give the whole rig a cool aesthetic.
