Frequently Asked Questions
Why haven't I heard about Sigma before?
Sigma is a product focused company that has been working in the vehicle and simulation space since 2009.
Being a product focused company, we chose to reinvest all our profits back into product development, or making our products better value for our customers. We spend almost no money on marketing, advertising, sponsorships, licensing and instead reinvest back into our products and our customers long term satisfaction. This is how we provide a truly unique product to the market, at such an unbelievable price. The only company in the space to provide billet made actuator bodies for better haptics, using premium American made motors and our own in-house motion algorithms.
So although you may have not heard about us through traditional means, you will eventually hear about the value of our products.
Buying Direct from Sigma vs. Buying from Resellers
Buying directly from us, the manufacturer saves you money and gives you a better quality product and service.
We are not buffered from our customers by our integrators, and so all support and post sales activities go back to us, the manufacturer of the product, so we can have an accurate idea of how our products are performing in the market. This allows us to immediately respond to issues, comments, concerns or even suggestions.
This is also why we don't call our integrators resellers or distributors. They don't just resell our products but properly integrate them into their products.
What's the difference between the DK products?
What makes Sigma's DK motion systems unique?
What other hardware do I need?
The DK motion system connects to almost any typical aluminum extruded chassis. Aluminum extruded rigs are the most popular type of material and can also be easily built into bases to hold tubular or other chassis designs. Sigma includes four brackets with each order. The power and data cables are also designed to snuggly fit inside the aluminum extrusion channel, making cable routing clean and easy. We typically suggest and use the following dust covers to hide the cables inside the extrusion: https://www.mcmaster.com/5537T319-5537T25/
I don't have a free Network port on my computer. What now?
Yes the DK motion controller connects to your computer via a network cable and requires a network adapter or a free ethernet port on your computer. We use a network connection because it allow for greater lengths and better quality of signal that supports our philosophy of Motion Integrity™. USB connections are great for standard peripherals but have length limitations and other challenges. If you do not have an additional ethernet port on your computer, we do recommend a USB to Network adapter. Almost any adapter will do.
What are the shipping costs and duty charges for my address?
Whats the length, height and width of the mounting bracket for a DK?
What is production time and shipping time?
How objectively loud is the DK system?
Does the controller consume any significant CPU processing power?
Why are you not FIA licensed?
We remain in contact with the FIA and hope that in the future they will create an actual certification, much like safety equipment, that is open to all manufacturers and is not an exclusive marketing tactic.
Do you offer discounts or deals on your products at all?
