All SimCraft units (except RTA spec) include pre-installed and pre-configured software in several categories:  Simulation Software such as, the SimCraft Control Panel which serves as both the motion control system and overall simulator manager, and additional supporting software such as Simucube True Drive.

Simulation Software Motorsport Simulations software has been a standard for SimCraft units since 2009.  We offer additional software such as the Assetto Corsa series, the rFactor series, the F1 series, and the DiRT series, among others.  A complete list of available software, compatible with SimCraft motion technology can be found here:  Compatible Racing Sims

SimCraft Control Panel

The SimCraft Control Panel (CraftCon) is the central hub of all SimCraft units.   From CraftCon, several dozen motion interfaces for any Windows PC based racing game are managed, and more importantly the real-time tuning and motion profile system for easy personalized customization of SimCraft motion technology.  Since every human is different, our motion tech is designed specifically to be tailored to every driver’s unique perception.  Adjustments to 20 parameters can be performed in realtime while racing.  Several baseline motion profiles are provided for fine tuning.  CraftCon also includes quick access to almost all Windows functions and serves as an overall operating and management system for our clients.

Additional Software

Software such as Simucube Test Drive and SimHub are also pre-installed and configured.  Test Drive controls the performance details of the direct-drive force feedback steering system.  SimHub is a feature rich dashboarding system that drives the data display unit, showing lap times, track maps, and many other customizable options.

Craftware SDK

The Craftware SDK is available to all SimCraft clients for custom developed motion interfaces for any bespoke or otherwise privately licensed user application.  The SDK includes full documentation and sample code.

All SimCraft APEX units are priced to include full assembly and factory testing, but additionally the training of the driver (or drivers) on the operation of the system, and follow-on product support for 3 years.


Training is always included in the pricing for SimCraft APEX systems.   For clients who opt for delivery and installation of their SimCraft simulator, our installation team is prepared to train you on everything from general usage of the sim, operation of the simulation software (such as, usage of the SimCraft Control Panel, supporting software applications, and even generic Windows OS usage.  The time required for training is based on our clients existing operational knowledge of the system.   For example, clients already familiar with iRacing (or supplied application software) and the WindowsOS will require much less time for training.   Clients with no WindowsOS or iRacing knowledge will take several hours longer.  Plan for a half day of training, with additional time for each addon application.   For shipped APEX units, we offer included remote training sessions to get you up to speed on all of the same topics as our onsite service.

Product Support

All APEX units include a 3-year support agreement.

Accepted payment methods include personal or business checks, electronic wire transfers, or ACH payments.  All major credit cards can be used for up to $10,000 toward your 50% production deposit.

Delivery / Installation or Crating / Shipping

Delivery & Installation or Crating & Shipping of your SimCraft is quoted.

Delivery / Installation

All SimCraft APEX units are designed for installation, almost anywhere.  Modular design allows any APEX unit to be disassembled and reassembled, which means if you have an interior room, a basement, a man cave, an office, or a spacious attic, there is a good chance your SimCraft APEX unit can be installed there.  A 32″ door and 36″ hallways are usually required, but we have accommodated clients with restrictions.  If you aren’t sure if your ideal spot will work, give us a call or setup a consultation.  Installation services are provided worldwide.


If you are a client that is picking up your sim from our factory, our staff will assist you with the preparation and execution of your load-up.

Crated Shipments, Installation by Client

Clients that are receiving a crated shipment and managing their own installation, your SimCraft will be shipped LTL.  If you plan to receive a large crate at your residence or a location without a loading dock, we have a proven procedure to offload the sim from the delivery truck. All SimCraft units are built 100% in our factory and burned-in, validating the configuration and setup. When crated and shipped, both side screens (if applicable) are removed prior to shipment. Once the sim arrives and is removed from its crate, remounting of the side screens is required, taking under an hour of time. In these cases, we train you on operational and application usage remotely.

Delivery and Installation outside the Continental USA

SimCraft units have been shipped to and installed in over 20 countries worldwide.  

Chassis Colors

APEX units are powder coated and have seven standard chassis colors


Textured Flat Black
Gloss White
Metallic Silver
Metallic Charcoal
Gloss Blue
Rosso Corsa Red
Gloss Black


We always recommend a textured black cockpit assembly (the inner most assembly for driver, seat, controls, etc.) as this coating is most durable for wear and tear.

Customized Chassis Colors

For our client with a specific color in mind, or for our clients looking to match a corporate color or historic livery, we offer thousands of powder coat colors for a customized look.  Once your sim is in production, we will work directly with you to get the color or colors you desire for your SimCraft.

Addon Steering Wheels

Steering wheels come in many shapes, sizes and functionality.  Addon steering wheels for the various forms of motorsport are available a la carte.

Addon Flight Controls

SimCraft motion technology was born in flight simulation and we continue to support flight sim software such as Microsoft Flight Simulator, X-Plane, and Digital Combat Simulations.  Many of our clients enjoy modular flight controls on their APEX sim.  Included in this package is a Thrustmaster Warthog HOTAS system and Precision Flight Controls Rudder pedals, along with a license for MSFS, X-Plane, or DCS, and setup and usage training.  With our quick release mounts for these controls, switching between racing mode and flight mode takes just a few minutes.

Addon Software Titles

SimCraft motion supports dozens of racing and flight simulation software titles, and therefor your APEX simulator can be utilized on these many different simulation programs and games.   For each software title added, your system will be setup and licensed, and you will also receive additional training on the operation of all addon software.

Branded Panels & Graphics

For our clients who have customization and on sim branding in mind, we offer branded panels and graphic design services to make your SimCraft APEX standout.

Sequential / Handbrake Option

For our clients looking for a rally car style shifter setup with a floor sequential and handbrake.

APEX systems are complete high-fidelity racing simulators that incorporate SimCraft’s proprietary, physics based, motion simulator technology. Our method and proven philosophy is designed to recreate rigid body dynamics, more specifically, recreate how any rigid body (vehicles and aircraft) move through Earth physics.  Rigid Body Dynamics has taught us that an object such as a car or a plane (both rigid bodies) rotate around three degrees of freedom, and translate along these same axes.  The origin of all 6 possible motions is at the center of mass of the rigid body.  The 6 degrees of freedom are also all independent from each other.  SimCraft motion technology follows these same known principles.  In a SimCraft motion simulator, all degrees of freedom are independent and additionally they all rotate or translate at the center of mass of the cockpit assembly (in this case, also a rigid body)

Degrees of Freedom: Pitch, Yaw, Surge and Sway

Pitch25°(+/- 12.5°)Rotation around the lateral axis

Chassis Build Quality – MADE IN THE USA since 2008

APEX systems feature a super-strong, TIG welded, tubular carbon steel, handmade chassis, built in-house at SimCraft HQ in Marietta, GA. With a robust 8th generation design suitable for high speed motion simulation, its strength and rigidity allow for unmatched performance and the highest standard in durability and longevity with a LIFETIME WARRANTY.

Component Versatility and Future Proofing

Simulator components such as display monitors will all eventually be obsolete and something better inevitably will be available.  SimCraft chassis are designed for component versatility and modularity.   Should you choose to upgrade your sim several years after purchase, new components can be integrated and utilized on your chassis with minimal effort.

Cockpit Adjustments

Human ergonomic adjustments are a key attribute of APEX systems for customizable preference for seating position and the driver’s relationship to their racing controls.

Chassis Upgrade Path

The SimCraft manufactured chassis utilized on APEX units are modularly designed, and are upgradeable.   Clients who start with a 2DOF CT unit on our smaller platform can upgrade an additional 2DOF up to 4DOF.   Clients who start with our 3DOF GT unit in our larger platform can upgrade over time to a 6DOF. 


Operating Length and Width is variable, determined by side screen size(s), side screen angles, and AV Rack or ACE Box location.  Dimensioned drawings are provided below to see all of the various configurations:








Operating Dimensions – Configuration Dependent

MAX 8′ x 8′ (2.4m x 2.4m)

MIN 6′ x 5′ (1.8m x 1.5m)


SimCraft APEX units have been installed in residences, offices, garages, car condos, race shops, research facilities, rehabilitation centers, and academic institutions since 2009.  We have seen it all and are intimately familiar with the right conditions for a perfect installation.

Power Requirements

A dedicated 20A circuit for 110/120V supply power is suggested for this unit.  (10A at 220/240V supply)


The data needs for your SimCraft are dictated by the application software you choose to use.  Modern Wifi is generally sufficient for simulator data needs, but racing with online human competitors is better in a wired LAN.  Bandwidth is not the only consideration however, reliability is also a factor.   Wifi is generally stable from device interference, but wired LAN is always connected.


APEX systems can be installed on carpet, rugs, or mats.   If your desired location for your sim is tile, hardwood, concrete, or vinyl, you will need to consider a mat or a rug for the sim to live and operate on.   We can supply basic matting upon request.

Conditioned Air

While all SimCraft APEX systems are built for reliability and durability, conditioned air for your sim installation location is a big consideration for the long term health of your sim.  Stainless steel hardware is used through the unit, but surface rust is still possible for garage or warehouse installs with no conditioned air and in the wrong climate.   More importantly, this is a system with lots of electronics and operating temperatures for the supplied electronic components is documented below.
