DEM DRS-LC Pedals Unveiled

DEM Simulators have unveiled their newest product, the DRS-LC pedals.

The pedal set comes with a professional linear potentiometer for the throttle pedal and a load cell powered brake pedal which supports up to 100kg and a spring with 60kg resistance.

For a maximum of precision, the pedals are being controlled by a 12 bit Leo Bodnar controller, which allows 4096 different values.

The set will soon be available for pre order, selling for 598€ (two-pedal version) and 769€ (three-pedal version) respectively.

    They look good, but seem to be bending or not very well mounted. Not a brilliant product demonstration.
    Couldn’t find any details on the 3 pedal setup either.

    • DEM Racing Simulator

      We’ll try to show some shots of the three pedals version soon.

    • Mark Quigley

      You want to see the bulkhead flex on some older cars when you stomp on the brakes. In fact, some flex in this area can help with modulation.

      • fazed

        I look at that and think if its bending like that over one lap, its not going to take long to snap.
        I guess I’m looking at it the wrong way.

      • Mark Quigley

        At least they are not taped down :D

        Looks like the whole unit moving and not the individual components flexing independently.

        I’m poor so i’m shutting up :D

      • fazed

        Yes better than being taped to a table cloth.

      • DEM Racing Simulator

        Well, driving with pedals on a table would have been pretty difficult. :D
        Hopefully we’ll see some better MadCatz video soon, as the first one wasn’t exactly a quality one. :)

    • Noel Hibbard

      I thought the same but I suspect this is a prototype or just not mounted to the cockpit very well.

  • John Karagiannis

    Really nice. Hope they are reliable as well!

  • wajdi nujeidat

    Wt? 876 euro for a set of load cell based pedals?! are you kidding me?!

    You cant easly spend less and buy an Hydraulic set pedals with only 650 euro for 3 pedals and 450euro for a 2 pedals set!

    This looks much much better and give you a much realistic feel!

    • DEM Racing Simulator

      We evaluated the possibility of going with a hydraulic solution, but we preferred the load cell: it gives a better feeling to us.
      We also think it would be better to try both sets before giving an opinion. ;)

        Respectfully, I don’t see how this is possible. Load cells don’t have the travel or feel of a real hydraulic brake pedal. In comparison, a hydraulic brake pedal feels like a hydraulic brake pedal…

        I’d love to take you up on your offer to try both back to back but I certainly don’t have your asking price lying around.

      • Ghoults

        Loadcell is just one part of the brake pedal mechanism. No matter whether you use loadcell or hydraulic pistons (or master cylinders) you will use springs and other mechanism in both cases to create the travel. There are springs inside the master cylinder and there is a spring in the loadcell mechanism.

        It is simply impossible for a human to feel the difference between the two simply because there is nothing there that is profoundly different from the other. Both systems measure the force, both system can be adjusted with springs and rubbers and what not to give the right combination of travel, linearity of motion, motion resistance and hardness. Hydraulic is just more messy.

        For layman the option to go with “real” master cylinder might look more “real” but mechanically it doesn’t offer anything you couldn’t do with loadcell and its mechanism.

      • Noel Hibbard

        Hahaha… You said it much better than I did. :)

        “It is simply impossible for a human to feel the difference between the
        two simply because there is nothing there that is profoundly different
        from the other.”

        Yikes, this has been proven incorrect many times. People going from the Perfect Pedal on the G27 complain about the Clubsport Pedal V2′s brake feel despite it being load cell, with a spring, adjustable AND has a hydraulic cylinder to help with feel.

      • Noel Hibbard

        This has nothing to do with one having fluid and one not. The perfect pedal has more inside it then just fluid otherwise there would be zero travel because the fluid doesn’t compress.

      • Ghoults

        Of course that doesn’t mean that all hydraulic and loadcell brakes feel the same. But if you want to create a pedal that feels in certain way it is possible to make the pedal feel exactly like that with both ways. Using loadcell or using hydraulics. Both system measure the load, the only difference is not what measured the force but how the force is mechanically connected between either the pressure sensor or load cell and the pedal.

        It is even possible to create hydraulic brake pedal using loadcell. It is all about the mechanics. not about whether you use loadcell or something else as long as it measures force and not travel like pots for example.

      • John Karagiannis

        Agreed but, for obvious reasons, its not possible to try all competition out to decide, so there must be something quite “visible” and “felt” in them that sets this product apart from the competition and justifies its price.

        Cheers and thanks for the nice vid.

      • LogiForce

        You think all of us are rich enough to try out both sets? Get real!

        Besides that trying out means I can send the set back I dislike. So can people send back their (obviously used) set back if they prefer another? Just wondering.

      • DEM Racing Simulator

        No one is suggesting any of you to buy both sets, obviously.
        What we asked is to lose that attitude that we’ve often seen in the past with racing simulators too. Our favourite sims are often judged by a video on Youtube, which leads to comments like “this game is arcade / that game is not realistic” without having even tried the simulator. We just asked for a fair review AFTER having the chance to try the set: we’re not saying that you must like it, just that we would like anyone to try it before saying it’s good or bad. :)

      • LogiForce

        So what do you suggest we do if we can’t base our opinions off of youtube videos? Mind you that InsideSimRacing also is just a youtube channel.
        The products are not available in a store, plus even the stores that sell stuff like Thrustmaster or Logitech hardware do not have them up on a rig to try. Sometimes they put some wheels and pedals on a shelf, but that is it.
        That said your and other companies’ products are niche products only sold directly by the manufacturer. So there is no store to try them in either.

        I am not saying your product is good or bad, and I agree that prejudices are a bad thing to have. However, I can’t agree entirely with the fact that you say I should try both before being able to give a valued opinion. Nor with the fact that we can’t base it upon videos.

        For example I can already tell that your 60kg spring will be an issue in replicating the real feel. The spring is bare metal (of some alloy) which bottoms out hard. This causes a spike to be transferred into the loadcell, plus you’d feel the jolt in your foot. This would not happen in a hydraulic solution. Brake fluid compression always happens in an analog gradual way. The only reason something would bottom out is if you have a leak in your hydraulic system.
        A solution would be to put something soft in between the spring windings. Yet should also be firm enough for a gradual compression while keeping the spring safe from the sudden bottoming out.

        So yeah, I might not be able to deduct the complete feel of pedals, obviously. Yet seeing what the mechanics are doing in a youtube video does give a good enough initial impression to base an early opinion upon. Granted it is not a final verdict, but they do also say that the first 5 seconds are the most important when meeting a new person… in which we tend to form our initial impressions and opinions.

        That said, thank god for different tastes and different products to cater to those tastes. So even if one person might dislike a product, another will like it.
        Just look at the 3 main camps in sim racing… Logitech, Fanatec and Thrustmaster. Each have their own following for good reasons.

        In any case… good business to you, sir. :)

        Let’s give them a break on this I am sure they put a lot of effort into this set of pedals and that is worth something. Regardless of weather their product is for either me or you or if we agree that we would spend the type of money or not that they are asking makes no difference until we are committed to do so. A person down the street may think it’s a great deal.

      • posi x mosh

        Keep it up man, I think its rad that yall fabricated and built your own rig how you wanted it built. Sure, I would do some stuff different, but that’s why I do DIY and my solution is nowhere near as neat and polished as yours.
        One question though, have you thought of using something besides a potentiometer for the gas and clutch pedals. You could try out a optical solution or even rig load cells to all three pedals as an upgrade or something. lastly, What kind of mechanism does the clutch use? Is it the same as the gas, or is it a two-stage type doohickey a-la fanatec’s CSP’s or the Frex Spaceship control pedal set they just released? Just curious…

    • Alexandre Martini

      yeah, it costs like 10 times the price of a fanatec csp with pretty much the same technology.

      • DEM Racing Simulator

        Come on guys, we know you can do maths: 250€ * 10 makes a different result. :)
        We’re not trying to say that our pedals are cheap: we know that it is indeed a lot of money, as we often see with many sim racing products. We tried our best to keep prices as low as possible, though: laser cutting every single piece has its costs.
        We also have Clubsports Pedals here: technology is the same, but we do believe there is quite a difference between these two sets.

      • Anonymous

        You might be doing a little better if it were a 3 pedal set. I also understand the manufacturing costs are more than Fanatec’s. Whole thing is we don’t care how much it cost you to have them built we care how much we have to pay. Anyway good luck with it I am sure you will have a market for these even if much smaller than the big 3 wheel makers.

      • posi x mosh

        There is a three pedal solution…

    • Noel Hibbard

      I don’t really understand how hydrolic is any better then a load cell. Fist off, hydraulic fluid isn’t compressible, so it isn’t going to have any effect on the feel. The fluid has to put pressure on something that has some give so it can “emulate” the feel of a real pedal. Simply using fluid doesn’t make it feel anymore real. The fluid pressure is then measured very similar to how a load cell measures pressure. In the end it is all about how much pressure you are applying. Making it feel like a real brake is the tricky part. The only way I see to fully emulate a real pedal would be to run fluid through a full brake system. So the full length of rubber hose (which has flex), to a caliper with pads that apply pressure to a brake disk. Then you could have a pressure sensor in the brake line somewhere. Even then this wouldn’t feel exactly like a real pedal because it wouldn’t have a functioning brake booster. Emulating a brake booster would also be tricky because the boost comes from vacuum which changes all the time too. So in the end it isn’t practical to go this route. At least not for mass production. It would make a fun DIY project though. For mass production I just don’t see how pumping fluid through a 2in hose is any better than using a load cell.

        You could just spend 250 euro and get some Clubsport pedals from fanatec the money you save can be used somewhere else

      • steve30x

        The CSR Elite pedals are good too. I own the pedal set and they are fantastic.

      • posi x mosh

        Dude, hydraulic fluid isn’t “compressive”, but air is, and even the most rigid hoses flex a bit. In terms of “feel” and realism, I’m not sure how you beat hydraulic pedals as they are what is used in the real deal. Sure there is no brake booster and the hydraulic pedal sets are miniaturized, but having used Hydraulic, pneumatic, and load cell based pedals, I’d rate them in the order listed in terms of overall feel.
        Speaking of over priced pedals, I’m selling some hydraulic pedals if you are interested.

  • GamerMuscle

    I bought 6 pairs to use on my key-chain , never going to lose my door keys again.

  • furiousgibbon

    When did sim racers become so utterly cheap? It’s shameful to read these comments. If you can’t afford it, you won’t be buying it. Don’t bag out the effort of these guys in bringing what is probably a high quality product to market. If you whingers ever progress to buying a real track car you will quickly realise how far a dollar goes and this stuff will start to look cheap in comparison. You’ll also realise that there can be a vast difference in cost between two products that on the surface look basically identical. For now though you can be thankful there are more affordable options out there. Reading comments here can be as frustrating as reading youtube comments. FIRST.
