Real cars benefit from a lower CD in terms of handling as its easier to change directions. Makes the car more nimbler. Simulators, specially motion simulators benefit from a lower CG as it bring the driver (the heaviest mass) closer to the roll center. Motors are better able to change direction this way. The acceleration and jerk curves look and feed different, at the compromise of degrees of roll. ;-)

Great questions, as there are no solutions in engineering, just tradeoffs. The drawbacks of having a wider stance is less degrees of experienced roll from the driver, as you are closer to the roll center by widening the chassis. This means that you experience less degrees of roll but achieve a better moment of inertia (or its easier for the motion system to change directions, which is what it does all the time). Just like in a formula style real race car. Even WRC (rally) drivers position the drivers much behind the B-pillar of the vehicle and down low. The co-drivers are even lower and further back to bring the center of mass as close to the center of the car as possible. This gives them "snappier" turn in and lower roll over risk, much needed in rally. So a chassis, like a race car, can change directions (yaw, roll, pitch - angular movements) much easier and it feels great. This is also a common point of discussion in vehicle engineering with various engine placements, some of the most heaviest parts of a vehicle. Do you place the engine in the front, front-middle, also called mid-ship, or in the back, like some Porsche vehicles? But in the end, the most optimal position for an engine, (best compromise) is in the middle for a lower or better moment of inertia. The new Corvette figured this out after many decades of having an FR layout, or front engine, rear wheel drive, which is more fun as an FR layout gives you better throttle exit (all other things considered). In the recent motion talk, this further helps lower the center of mass in your simulator. ;-)

That's so hyper specific that I am suspicious.

Hey John. You are correct. The most mechanically optimal actuator placement is a square design because you get an equal amount of mechanical pitch and roll. Most chassis designs, like this one in the video, are optimized for the driver and hardware and tend to be more rectangular in design. This is one of our test chassis and we made it exceptionally long (70" x 32") to test various actuator mounting locations. We are also using Vention.io extrusion with special locators to keep everything square and tight at such lengths. As you already know, our software prompts you for your actuator location on initial startup. This is to ensure that the roll and pitch is proportional to what our software and algorithm expect. If the chassis actuator mounting is perfectly square then almost no corrections are made to the pitch and roll ratio. If the chassis is exceptionally long (say 100" apart that gives a smaller pitch angle) and very narrow (larger roll angle) then our software will correct this automatically with the measurements provided. This test rig will receive further updates from us, we need to lower the pedals and seat, square off the motion and use shorter side seat mounts. ;-) We have seen so many rigs over the years, and each rig is definitely different...

Ah, gotcha. Didn't realise it was a test rig. No way in hell was I going to be moving mine again anyway. Ha!

@@johnangel5134 😅yea it's easy to install our system, but time consuming to move everything else around and do cable clean up. We have 6 different test chassis in house. 3 tubular chassis and 3 aluminum extrusion chassis. Each one offers all types of different feedback to us.

Rookie mistake. Also pedal USB cable was loose and prior to this I was losing the brake and gas. [ lame excuse ]

Thanks Badger, its one of those topics that is simple at first, but can get complicated rather quickly. But center of mass or center of gravity is best kept low for most performance applications, on and off track. Unless you are hauling something in American Truck Simulator then a higher seating position better mimics the real life roll center you get in a truck. When we did our REAL remotely operated Peterbilt 579 truck back in 2016 we faced a similar decision. ;-) kzbin.info/www/bejne/i5e0oXiJoJV6Z68si=gJCoTaKPkQkxuQVO&t=87 Driving the real truck "felt" different than driving in the our simulation software and in our remote emulator, remote controlled rig. Turns out putting the IMU or the unit responsible for collecting the real vehicle pitch, roll and heave data was important. Do you put the IMU in the center of truck? Do you put it on top of the driver, or the left side of the cab? All these different locations "felt" different. The DK6+ has multiple mounting positions for this reason too. Of all our products it allows you to mount the actuator very high on the side extrusion or allows the chassis to sit lower. This is also required, as 6" is a lot of travel.

Great question. There are some customers who have managed to connect it to a network switch, but does require your switch port to use a .1 address... We are working on a release that auto-detects the controller on a LAN and allows for custom IP subnets to be used for the computer and DK controller as well. This will allow much easier network operability.

Good question! The word Sigma is not just a social idiom or meme but is a summation symbol in mathematics. It means the summation of all parts. For our name, we believe that the final product is summation of its parts and its proper integration. Hence the name Sigma (summation) Integrale (integration)... Its mathematical.

You better believe it.

Yes, many of our customer use ethernet to USB adapters. They work great and still give you the benefits of a network connection. Mechanically connected, low interference and greater lengths when required.

Good question. Unfortunately, no since the ClearPath software only runs on Windows. Unless you have Windows running on your MAC laptop.

Thanks David! Let us know how you like it! And don't forget to spread the word! 😆

You can also use a laptop or windows tablet if you have one. 🤷

yea please shoot us an e-mail [email protected] . Should be a simple resolve. ;-)

The BeamNG IP assigned as the controller will not work unfortunately. The controller IP is fixed at 192.168.153.2 your computer should be fixed at 192.168.153.1 (network card connected to the DK Controller). The computer loopback address should be 127.0.0.1 in the game, as in BeamNG here. Most likely the cause is ports mismatch or unavailability. Can you please make sure that the 4444 port you are using for motion and 4445 for the gauges (engine vibrations). Also ensure that the motion is set to 100hz in BeamNG. We are able to do 300hz, but needs more tunning and right now has some unfavorable noise.

Thank-you! This is where the DK was born, with such crazy projects. Believe it or not, your DK2+ is better suited for this application than the actuators in this video. The pistons are larger, stronger and better suited for side loading. :-)

Took us 4-5 months to execute. Having the projectors so close on the windows seemed like a good idea, but it only works for the driver. Passengers feel like they are always drifting, this is because the vanishing point is more pronounced the closer the screen is to the driver. Luckily ATS and ETS allows for the position of the vanishing point. ;-)

Thanks for your input. No doubt that $9000 USD is a lot of money. What other turn key systems are you comparing it to? The DK product line is engineered to be simple to install, easy to run and requires no ongoing maintenance. We also provide some of the best support in the industry. ;-) Our systems is also the only turn key system that is fully CNC'ed from billet, uses unique and powerful (yet efficient) @TeknicInc American motors, customer controller and our own unique in house software and algorithms. Just need to compare apples to apples. ;-) What flight sim do you mainly play?

Ok, turnkey and support is an argument. Still for me who likes to build from kits DYI is no hindrance. I fly mainly DCS and a bit MSFS so larger strokes with fast speeds are a good cushion when it comes to more extreme manoeuvers.

Lot's of great companies in the space already making great components. :-)

Sigma or Σ means summation, or in our case the importance of all the parts properly integrated, "integrale". 🙃 Yea, we are engineers and not marketing people. Obviously.

The model from @beamng is awesome and works so well. Very well setup. To make a @Polaris model would be too costly and mostly unnecessary in the NOSE camera view that we typically use. This 3rd person view is more for our testing during setup. ;-)

Well that may be true, but I was thinking like KTM themselves made an actual mod for Assetto Corsa for their GT4 car.

Definitely. We have ruggedized the RC cars with custom carbon fiber bumpers and chassis, BUT after 3000-4000 rides per show, the cars do get used up quite a bit and need some work. Often steering linkages, wheels, motors, mounts, etc... all need to be redone at the end of each show. It's awesome fun and Volkswagen definitely knows how to have fun. Should be available at your next major auto show, Los Angeles, Chicago, New York or Detroit.

Oh wow! You guys are actually putting effort and thought into the end users experience. I'm into the R/C hobby myself so hearing that got me excited! Hopefully I'll be able to make out New York to come see you guys in person and try out your rigs.
