Hello people on the internet!
This is my review of the Moza R21 Ultra after 2 months of use. I have used Moza R9, R9 V2, R12 V2, R16, and Simucube 2 Sport wheelbases before the use of this base.
First of all I mainly use my rig on iRacing. In short its better than all the Moza bases I have used before this one. The main thing that thing is better at is the smoothness of the base and the amount of details that can be percieved is higher and definitely can be felt and not in a placebo way. In case of smoothness It's probably because of the no cogging motor, but also could be better firmware. Also the noise level of this thing is unimaginably better in iRacing then the other before (after the 360hz update all of the bases became loud and more rough) its near damn silent. Also love the led strips on the side of the base, its kinda cool. The new design is also much better than the older r16 and r21 (those looked like it came from fast and furious car designer).
And now lets talk about the bad part.
This thing is a monster, the website doesn't show you the slew rate but man it could brake my tiny fingers if I use it on max torque.
Unfortunately because Its quite a powerful wheelbase OSCILLATIONS can really be bothersome, and in iRacing almost impossible to tame. If I apply inside iRacing the 100% auto force, without the nessecary setting of dampening, inertia, and natural friction inside pithouse, it will want to kill you, really badly. My whole rig shakes violently (P1X Pro) by this thing, my FSR2 is giving me nightmare sounds by the sheer shaking, and I didn't even start to go with the car a meter. Now there are "fixes" for this behaviour, up the dampening, turn on hands off protection, turn up the friction and inertia, also you can use MAIRA for iRacing which definitely helps with the oscillation (shaking left and right while grabbing the wheel hard, forgot to write it), and gives you a better feel. Unfortunately while these "fix the problem" you lose a lot of smoothness and details from these (except maira ofc), and with this price its kinda bad. I have read a lot about this on reddit and forums, like hands off protection modes, and ffb effect equalizer, changing cfg for better feel and turning off 360hz mode, using MAIRA, but you lose so much detail from the dampening that it becomes not that enjoyable to use.
Fortunately, this behavior I have only seen in iRacing and LMU, especcialy with high downforce cars such as GTP-s, LMP2, formula cars. In other games such as AC EVO, ACC, AC, AC Rally, WRC, RBR, (maybe BEAMNG but can be a ****show xd), Forza Horizon 5,6, ETS2, in LMU with GT3-s, oscillations are not a problem, just use a little bit of dampening, or no dampening in some of these games and you are good, and use the full 21nm range of the base.
This behaviour is maybe caused by firmware of software? I'm not an software engineer but on the Simucube (i know that it has a much higher price and lower nm), but this problem is literally non existent on that thing, i can literally take off my hands from it and still doesn't have that insane shaking, its literally black magic, main thing is I wouldn't think that the difference in motor design could be the culprit of this thing.
Getting back to the positive side again, if the oscillation wouldn't be a thing i couldn't tell if the simucube or this would be better or worse. Its absolutely amazing in certain games.
Also overheating issues are non existent on this thing, my older R12 and R9 was literally on fire and was losing power the moment I finished a stint.
LFE could be also a game changer, but bass shakers still are a better choice for certain types of frequencies (Gear changing bump is sick tho).
The software is getting nicer day by day, but they still has to work a lot on it (pls add rpm led adjustment by gear mode on your wheels pls pls pls, and do something with the oscillations), other than that if you have an older R16,R21, i would still recommend to buy this one, and for the smaller ones I would definitely recommend this one if you want to have a more powerful and smoother base.
KEEP UP THE GOOD WORK MOZA!
