    I am going to present you the Motion Simulator NjMotion SV-2

    The SV-2 is a commercial pre assembled motion simulator which is developed and sold by our member NjMotion - I call this one a RtD, a Ready to Drive simulator because it needs almost no DIY work to make it running, except installing and configuring SimTools.

    SV-3 incl.- traction loss

    The SV-2 is a interesting product because it is placed in the semi price range and therefore affordable for many users.

    I am curious for testing it because the SV-2 has a few advantages compared to other (commercial) motion simulators:

    Main Features (not tested,yet)
    • 100 - 140mm travel adjustable
    • 50 - 180mm/s speed adjustable
    • 40Kg of force per actuator
    • Potis for adjusting the speed and travel distance in real time while driving
    • Very quiet, almost no noise
    The SV-2 is using industrial Servo Motors which are created for high efficiency and accuracy so theoretically it should be running more accurate and faster than any wiper motors.

    There is also a version called SV-3 with one more pivot and with traction loss.
    I ordered the SV-2 because i am mainly driving with a VR headset and need to compensate the movements of the simulator from the oculus rift view. Doing this for two axis is hard enough so i first try to find out a drivable constellation with a 2 DOF setup. (Maybe i am able to create another axis in the future.)

    Delivery time:
    • Estimated delivery time is from 1-2 months
    Order:

    You can order the SV-2 and SV-3 via PM or Facebook

    Prices (09.05.2017):
    • SV-2 € 2000
    • SV-3TL € 2800

    Today the little box is going on its way:

    fabafaf9-cf69-458f-81ff-7e8dab9d9d42.jpg

    I keep you posted when it arrives and i am able to have a first test run.

    I thought you of all people would build your own @RaceRay :D

    It looks pretty good though for the price, look forward to your review

    I did built my own SCN5 based simulator in 2012 or so and sold it a short time after finishing it. Journey was the goal:) Now it's time for me to let other guys do the job - much better and more professionally than i was ever able to do. In 4 days the sim will arrive.

    The Simulator arrived today. Had a busy day with unpacking that beauty and carrying it to my top floor.

    First impressions:

    • Very well packed
    • Heavy. I estimate 80kg
    • Rock solid. Even Schwarzenegger could not bend the frame. It's a pleasure to look at the accurate welded joints.
    • Very good looking and clean matt painting
    • Absolutely no play anywhere. Nothing is moving and the complete construction is from very good quality.
    • The total length of the frame can easily be adjusted as well as the height of the steering wheel mount and the angle of the foot pedal holder
    • Had a first glance at the motors and amplifiers. These are indeed expensive industrial ones which are connected to a strong gearbox. I assume its a worm drive but i don't plan to disassemble the components:)
    • The interface and power supply including amplifiers are build into the case which sits on top of the motor body.
    • Only two cables, USB and power are going to the outside.

    Now i am connecting the sim the first time to SimTools and do first testings.
    So i will update this thread soon.

    RaceRay,
    Like your new sim..................I visited their website and it's hard to understand their "dropdown" options -
    I may be interested in the SV-3 - but need to understand the info and what the options are.

    I would like to talk more with you after you have received yours and had some hours simming - to get your pros / or / cons.

    Thanks for your thread.

    Tom

    Hi,

    Just wondering if you have had the chance to test this new rig yet? @RaceRay
    I know you haven't had it long but any feedback on your first impressions would be good to hear.

    I have been following the forums for a few months & have read many of the top diy simulator build threads here all the way through. I'm still weighing up my options with regards to either building my own rig or buying a kit of some kind. Ultimately, I would love to have a 6dof setup in the mould of @SilentChill 's using linear actuators, but it is outside my level of understanding for this type of thing at this stage, having looked into it quite deeply. So basically I am now really considering a 3dof with traction loss & this model you have (or the SV3) seems to be potentially good value for money.

    Also, if you have any observations of how well it works with VR, that would also be very much appreciated.

    Thanks :thumbs

    Hi guys,

    i am very busy at the moment but i already created a first video with the simulator on track. My overall experience with the simulator so far is excellent. So let me summarize it for the moment:

    The thing i really like is that the simulator is already prepared to be used as a full motion platform and not only as a seat mover which i am currently running. There are knurled-head screws which allows you to attach pedal and wheel holder to the moving base. The engine transmission unit is also more than strong enough to operate with the full body width. The frame is made of 40mm square tube which made to resist even the heaviest driver.

    My first setup is far away from perfect. The seat is temporally attached by me with rests of my garden sheds. This results in in this cracking sounds which you can hear in the video. I will also mount it to a lower position which is more comfortable to reach the pedals. The simulator
    itself is very silent and nearly unhearable. I will do another video later to proof this:



    The track i am driving in the video is an Assetto Costa mod track (Hockenheimring). Unfortunately this is not a laser scanned track and it does not includes any surface road irregularities. So there is not much movement except the usual driving g forces. Driving the Nordschleife is the opposite and even the smallest bumps and road irregularities are noticeable with high resolution.

    In the video i am driving the simulator with pots adjustments of speed: 45% and travel distance of 35%.
    The best is that you can adjust these values just in time during the race so you can adapt the speed and travel perfectly to the car and track. Therefore you have two pots attached to the kill switch.

    If you have any other question which i can answer just let me know.

    Hi @RaceRay

    Do you have any further thoughts on your new rig, now that you've had it for a few more weeks?

    How are you finding the type of feedback it offers, in relation to what is needed for a good VR experience?

    Thanks

    Hi @Coop

    i was on a few business trips during the last weeks so i did not had time to drive the machine :(
    For a good VR headset experience you definitely need a motion cancellation method. I am using a rift touchcontroller and the motion cancellation software mentioned here: https://www.xsimulator.net/community/threads/vr-motion-cancellation-time-to-test.10241/ This works very well and all the simulator movements are deducted from the headset movements without any noticeable delay. This give a

    The NjMotion V2 and the Rift together delivers an astounding virtual reality experience and very realistic sensation as far as i can evaluate it with my non professional driving expertise:) When i find some time i will convert the simulator (for testing) into a full moving platform and compare it than with the current setup. I am curious to know which one feels more naturally. Videos will follow than :)

    Thanks for the reply mate. I appreciate your information. It shouldn't be too long until I finally have my own motion rig - it is similar to your model but also with traction loss. I will certainly use the motion cancellation for VR, I have been following the thread and just need to decide which VR headset to go for now.

    Looking forward to any videos you share. :thumbs

    hi @RaceRay , thanks for your sharing of the NjMotion, it looks great!

    I am new to sim racing, would like to go for a motion rig which is better in simulating the motion of a driver on the race car seat...I am not good in technical stuff, so only way is go for a commercial one:(...I initially want to get a SimXperience stage 3 / 4, but the size and noise is an issue...when I saw your review of the NjMotion it really impressed me. I know there is a motion platform called CXC, from their videos, it seems to me that their motion rig reacts very fast, even though the travel is not large is it using SCN6 or sth similar? I live in Asia, not able to try CXC or the NjMotion, I just tried SimXperience stage 5 once, which was good, but I can't recall the memory that the SimXperience is as responsive as the CXC....

    From the NjMotion videos, it seems they are responsive too, but can't find a video which involves a lot of fast motion like this from CXC :

    Money wise NjMotion is a very good option, but I have not much idea on the performance difference between motor driven and SCN5/6 driven seat mover motion rigs. It would be very great if you can give me some idea / experience sharing on a comparison on the NjMotion and other seat mover motion rig, especially SimXperience? Thanks again!:D

    I've never driven a SimXperience simulator but i had a self build SCN5 based seatmover a few years ago.
    My personal opinion is that the NjMotion is much more suitable if you have family members living with you in the same household. SCN5 systems are great from the motion aspect but they are extremely loud.

    Servo based simulators like the NjMotion one pairs a very quiet simulator design with rapid and strong movements. The accuracy feels the same like using SCN5 actuators. My comparison is below:

    SCN Actuators Pro

    - Very accurate
    - Fast Movements
    - Easy to connect

    SCN Actuators Contra

    - You should not have neighbours or even a girlfriend - Yes, they are so loud;)

    #################

    Servo Pro

    - Very accurate
    - Fast Movements
    - DC Motor cheap

    Servo Motor Contra

    - More affords to connect and program them
    - Real servo motors as they are used by NjMotion are expensive as well


    #################


    DC Motor Pro

    - Cheap

    DC Motor Contra

    - Much affords are needed to connect and program them
    - Less accuracy
    - Less speed

    Hi all,

    I have recently (last week) bought a NjMotion TL3 platform and I can say that you won't be disappointed.

    As a disclaimer, I do not have prior experience with motion platforms. I have been lingering the forum for some time now trying to learn stuff and deciding if I had the skills to build my own platform but since time, space and tools are limited I decided to buy a platform instead.

    From the possibilities I saw, NjMotion was the one that ticked more boxes (price was also a factor obviously). Since the builder is "only" 300km away from me I requested to pick the platform personally to save a few extra euros.

    While I was there picking the platform, the builder was able to fabricate some custom supports for my shifter and handbrake and I must say that he knows what he is doing (jealous mode on.. :) ) while working with metal.

    The platform uses some heavy duty motors, allows adjustments that will suit everybody and is very well built. I am a big guy (1m90, 110kg) and the platform has absolutely no problem in moving my arse.

    One of the things I really liked on NjMotion's approach is the control box with some knobs to control speed and travel. This gives you a very simple and fast way to dial things up or down when you don't want to mess with the profiles.

    I plan to put up some videos when time allows it and answer any questions you may have.

    Cheers,
    Nuno

    This was my first thought when i saw the welded frame the first time.

    Feel free to post some videos and images into this thread as well. So we can collect the NjMotion stuff here in one place.

    Hi @RaceRay ,

    Thanks so much for your comment and info, very useful indeed! I am trying to learn as much as I can in this forum but due to my limited knowledge and time.....this kind of straight comparison definitely help a lot. I have been struggling to go for a frame mover or seat mover for a while. Beside SimXperience, I also tried D-box, which is also great, therefore I also thinking about Prosimu...I am not going to say which one, seat mover, frame mover is better, totally agree that it just a matter of taste, so...still looking for more information to make the best decision, (truth : still working hard to earn that amount of money...:rolleyes:), but definitely NjMotion is in the watch list now:)


    Hi @Nuno Figueiredo ,

    That's very good to have latest customer review, thank you so much for your sharing! I like that knob design too, it is very nice to change the motion profile in the fly, could you tell me is it auto-saved after you change from one race title to another one? Or do you need to tune the knob every race?

    You mentioned NjMotion provided you a custom for your shifter and handbrake, that is important to me too! could you post some photos of those part on rig? I am sure there will be a lot of questions from all of us, really looking forward to your video!;)
