Hi all, my fist post so be gentle with me! (Also forgive me if this should be in another category).
I have a DOF Reality H3 and am underwhelmed with it in MSFS. It’s the jerky motion and I’m unconvinced this is the DOF motors/gears as others allude to (cogging). It’s smooth as silk in Iracing including very slow banking turns (trying to mimic the slow banking turns and pitch changes in flight). Further, in the test utils I can move the rig ever so slowly to the max movement - smooth as silk.
Which makes me wonder, is it the MSFS telemetry? I think it must be but my mind can be put at rest if others could answer these q’s…
Does anyone have a non DOF realty motion rig and can confirm if movement is smooth?
Does anyone with a DOF rig use xplane? Is the movement smooth or jerky?
If anyone uses an actuator motion rig with msfs, is the movement smooth or jerky?
I love msfs and my H3 is astonishing with Iracing/ACC. But the jerkiness is such an immersion killer for me in msfs. Yaw is convincing but pitch/roll extremely poor I think. (I have a PPL with 200hrs).

I’m currently in the process of adding a DIY 2DOF motion platform to my 737 simulator. It is still early in the project, so no motion on the simulator base yet. I have however tested my actuators to check my motion “tool chain”. My impression is that the motion is smooth. I’m using SimTools V3 and a Thanos AMC controller. I uploaded the test to youtube:
Thanks guys, good to know. So it sounds like others could be right that it is the DOF motors. I can’t fathom though why the action is smooth using everything but msfs. I’d have thought if cogging was the problem I’d be able to repro that in the test utils. Or possibly could be how sim racing studio handles the telemetry.
(That’s a very impressive project you have on the go there by the way)..
Go to the DOFRealityBuilders Facebook group for PLENTY of info on this issue.
Many are complaining about the cogging issue in flight sims, and one member has recently come up with a no-cogging mod. Those who installed it say it works well, but it means you have to change at least two motors on your rig (roll and pitch). The new motors use planetary gears, and that seems to take care of the cogging.
I have ordered a DOFR platform myself and I will check that cogging issue very carefully - but I‘m already bracing myself in expectation of the additional expense…
Thanks just read that no cogging mod it looks very interesting indeed. The new planetary motors seem incredibly cheap compared to the £400 ish per motor DOFR charge (i have the SFU).
I’m reluctant though because the experience in Iracing is so breathtaking. Worried the speed of movement may be affected with the new planetary gears. I cannot describe just how good the H3 is in Iracing and VR. I have 3 Dayton haptic thingys and two Seaflo bilge blowers for the wind plumbed in which all add to the immersion.
I am also toying with the idea of getting into racing in VR with the DOFR platform.
But my big love is flight, so this is what the platform must deliver on, first and foremost!
How do you feel about the issue today? Have you gotten used to it or is it still an annoyance? I consider buying the DOF P3 but I read about this issue more than once and it doesn’t (yet) seem to be resolved.
Just a thought here from an outside observer - he states that he gets smooth as silk motion in anything but MSFS. How could a motor be the problem? Gears wouldn’t be the problem unless the load changes. Thinking logically, the likely culprit is somewhere between MSFS and the motor.
Hello all, I am also almost desperate after waiting for so long and having spent so much money.
Yesterday I finally went for a test and…
I can feel each and every little movement increase… flying steady I feel little bumps in case of small angle changes, and on normal turns or climbs/dives it’s really a series of little bumps rather than real movements.
This can’t be true. There must be a fix. I only do MSFS, and there’s no way I can return this rig all the way to Ukraine…
I think it lies in the software. Not sure what you are using but for my NLR V3 motion platform I had do dial back the movements in the software to get a more realistic set up. Hopefully your software has a nice set of settings.
I dont have motion yet but I’ve built FFB controls. Your issue sounds like a low positional update rate, which you would definitely feel. Does the cogging feel even, like the ticking of a clock? The fact the the issue is only with MSFS would indicate that it’s the send rate from MSFS, not the receive rate of your hardware.
Confirmed. The juddering is still there in DCS World. The planes you fly swing pretty dramatically, so the “perceived” bumpiness is less. I suspect this is why the rig feels better in racing as well. Lots of quick movements.
DOFR finally acknowledged the cogging issue in flight sims and is working on a fix (or at least an improvement). I got myself a P6 by now and I‘m quite happy with it. The cogging is there, but so is the feeling of motion. Turbulence in a 737 feel quite real. And I love the feeling of deceleration when breaking after landing.
I have my motion dialed way down (I think, less is more here), and I use a butt kicker, which masks some of the cogging.
But if DOFR can fix the cogging at an acceptable price, I‘ll get that fix and (hopefully) will be a happy camper
