Why this model

Three engineering decisions that define this product.

Feels the Rear Step Out

Surge and yaw reproduce rear-axle traction loss as a felt rotation cue, so the chassis steps out, not just the screen.

The driver counter-steers before the visual scene settles, building the oversteer reflex that rally, drift and GT racing rely on.

A 3DOF platform forms pitch, roll and heave but never yaw or surge, so the step-out cue goes unfelt.

Stacks to True 5DOF

The module mounts under a QS-210 or QS-220 set: chassis surge and yaw (fore-aft slide and rotation) on the base, suspension pitch, roll and heave on the cockpit.

Each cue arrives at its natural mechanical layer, and the two stages bolt together without a frame redesign.

On a single-stack platform, chassis and suspension blend into one softened event, blurring a line the driver should read.

Starts as a 2DOF Base, Grows Later

Running solo, the module is a standalone traction-loss base when a full 3DOF set is not yet in the build - or a surge-and-yaw stage for the supported flight simulators.

A training center adds rear-axle or rudder-yaw capability first, keeps the initial outlay down, and layers a 3DOF set later.

A bundle-only platform commits the whole 5DOF stack to one purchase, leaving no staged path as the fleet scales.

Package & Options

What's in the Box.

Hardware, software and licenses included with every unit - plus the optional add-ons available on this model.

Hardware

  • QS-CH2 Unit
    A 2DOF traction-loss base - two longitudinal actuators add surge and yaw (rear-axle step-out) under a stacked cockpit.
  • QS-SB2 Power Cabinet
    Under-rig power and control, driving the two actuators over M-BUS to the controller.
  • Anchoring Plates
    Four floor plates that anchor the base for a stable footing under cockpit load. Anchoring is recommended - under hard braking and yaw cues an unanchored base can creep across the floor over a session.
  • Cockpit Brackets
    Four universal adapters to carry an existing cockpit on the moving base.
  • Motion-Lock
    A hardware stop switch - press it and motion cuts at once. Travel comes to a controlled stop and the module ignores motion signals until released.
  • Power & BUS Cabling
    The mains and M-BUS cables - the unit wires together as delivered.

Software & Licenses

  • ForceSeatPM
    Auto-detects 154+ supported games with pre-tuned profiles. Included free, with free software updates.
  • Sim Profiles
    Pre-tuned motion profiles for the popular sims and games, so the first session already feels right.
  • ACE
    The motion cueing engine that turns simulator telemetry into felt acceleration - the sharp onset of a bend or brake on the platform, with sustained forces held by coordinated tilt rather than a crude static roll.
  • VR HeadWay
    VR motion compensation that cancels the platform's own movement from the headset, so the view stays stable and motion sickness stays low. Included free.
  • Docs & References
    Technical docs and mounting references to design the rig around exact mounting points. Complete CE-marked equipment (EMC 2014/30/EU) - tested to run without disturbing nearby VR tracking, radio or wireless links.
  • 12-Mo Warranty
    12-month commercial warranty, extendable on request; retail and consumer get the standard 24 months. Free software updates throughout.

Optional Hardware

  • QS-MC6 Controller
    M10 + Qubic protocol, linking PC to platform - required unless one is already on hand. One per simulator.
    350

Optional Software and Services

  • ForceSeatMI - Motion SDK
    Motion SDK to drive the platform from custom software on top of ForceSeatPM. Licensed per motion platform, with the key stored on the PC; multiple platforms on that PC mirror the same motion.
    850
  • ForceSeatDI - Direct Interface SDK
    Low-level SDK that drives the hardware directly, without ForceSeatPM - each platform driven independently, on Windows, Linux or Raspberry Pi. Licensed per platform, with the key stored on the motion controller.
    2 750
  • Remote Training (online)
    Six-hour online session - overview, safety, operation, maintenance, ForceSeatPM setup, diagnostics and tuning. Per session.
    1 800
  • VR HeadWay CrossPC
    A paid VR add-on, licensed separately from the base VR HeadWay. One CrossPC license covers exactly two VR users on a shared platform - each seat has its own rendering PC and geometry-correct compensation (for example pilot and copilot). More seats need an additional license.
    1 900
  • Motion Theater
    Plays pre-authored motion with video or group sessions - for theaters, attractions and briefings, not live sim. Per platform.
    1 300
  • More Options
    Profile packs, installation, reports, extended warranty and bespoke development - talk to the Motion Systems team to tailor it.

Feel the forces the motion generates.

The QS-BT1 Seat Belt Tensioner pulls on the racing harness in sync with the motion - braking, cornering and traction loss on track, climbs and G-loading in flight, all become physical. Fully compatible with the QS-CH2.

  • 200 N (20.5 kg) pull per channel - two independent channels
  • Direct-drive: no gearbox backlash, precise torque control
  • Whisper-quiet, built on Qubic System drive technology
  • RGB status lighting - brake, reverse, force, yellow-flag and DRS cues
  • Plug-and-play on supported titles: bolt on the included brackets, fit the seat harness, connect USB, and drive

Deep Dive

How It Works.

QS-CH2 · Traction Loss System

Two longitudinal electric actuators, paired with a QS-SB2 power cabinet under the floor, drive the QS-CH2 along a single horizontal axis. The cockpit bolts to a frame that pivots at the front, so when the actuators push and pull together the rear of the rig steps out - that geometry turns actuator travel into both surge and a yaw rotation, the cue a 3DOF set cannot form.

The M10 controller takes telemetry from ForceSeatPM and converts it into coordinated actuator extension under 8 ms, so braking and oversteer cues read in sync with the sim. The pairing is not limited to driving titles - in the supported flight simulators the same axes render rudder and crosswind yaw cues and deceleration after touchdown. The platform self-calibrates on start-up, runs on 120/230V single-phase power, and stacks under a QS-210 or QS-220 set for 5DOF or runs standalone as a 2DOF base.

A Motion-Lock switch brings travel to a controlled stop, and the module ignores motion signals until released.

Frequently Asked

Questions the team gets first.

Setup, supported titles, latency and software integration - answered up front, ahead of the first call.

Qubic System sets up in hours: the platform and ForceSeatPM auto-detect supported simulator titles with pre-tuned profiles, no code required. The customer supplies the PC, title and controls; the ForceSeat SDK covers custom integration.

ForceSeatPM auto-detects a wide range of supported simulator titles with pre-tuned profiles, and the ForceSeat SDK and API cover custom telemetry for bespoke integrations.

Yes. Qubic System accepts add-ons such as the QS-BT1 seat-belt tensioner and the QS-CH2 module, so a rig can extend the effects and axes it delivers over time.

The ForceSeat SDK streams telemetry in C, C++, C# and Python with Unity and Unreal Engine plugins, and the Hardware Imitator M10 lets integration code be written and validated in days, before the platform arrives.

Qubic System hardware is often in stock and typically ships within 1-3 weeks, with the exact date confirmed at order. Integration work does not have to wait for delivery - the ForceSeat SDK lets custom development start ahead of the hardware.

Every platform ships with a warranty, diagnostic support and access to spare parts, with the exact term listed in the box above. Extended service options are available for fleet and training deployments.

Integrate the QS-CH2 into the project.

One team scopes the build, carries it through integration and commissioning - with integrator partners where a full simulator is the goal - and stays involved once the rig runs in the field.
