In a real car the first thing that tells you how hard you are braking is the harness pulling against your chest. The Qubic System QS-BT1 brings that exact feedback to your rig, no platform required. A dual channel direct drive tensioner built on the same actuator technology as the QS-220, it physically tightens your belts in response to braking, cornering, traction loss and lateral load. Two hundred newtons of force per channel, applied where your body actually reads it. No haptic pad or bass shaker reproduces this, because it is not vibration. It is force, the same way a real car loads you when you stand on the brakes.

  • 200 N of force per channel, genuine G force simulation
  • Simulates braking, cornering, traction loss and lateral acceleration
  • Engine vibration, gear shifts and road texture via telemetry
  • 8 ms latency, same direct drive technology as QS-220 actuators
  • Works standalone or alongside any Qubic motion platform
  • VR ready
  • 2 year warranty for personal use

Our Recommendation The QS-BT1 is for sim racers who want belt tension synchronised with their motion platform. Most users describe harness loading as one of the single most effective immersion upgrades you can buy, on the same level as the first time you felt motion at all.

Frequently Asked Questions

What software do I need to run Qubic System products?

All Qubic System products use Qubic Manager, which is free to download from qubicsystem.com. It runs on PC only and is compatible with all major sim racing titles. No third-party software is required for basic operation.

What is the QS-MC6 and do I need one?

The QS-MC6 is the motion controller that acts as the communication link between your PC and the Qubic actuators. It is required to operate the QS-210, QS-220 and QS-CH2. If you already own a QS-MC6 from a previous Qubic System purchase you do not need another one — one controller can manage up to four actuator sets. If you are buying your first Qubic product that requires it, select the variant above that includes the QS-MC6. Not sure whether you need one? Contact us before ordering and we will advise.

What is the difference between the QS-210 and QS-220 actuators?

Both deliver 3DOF pitch, roll and heave. The QS-210 uses more compact actuators with a shorter stroke and is designed for installation in popular aluminium profile cockpits with the included bracket set. The QS-220 uses the full industrial-grade actuators — the same ones found in the QS-V20 and QS-S25 professional cockpits — with a longer 100mm stroke and greater force output. The QS-220 is the more powerful and more expensive option, suited to customers wanting professional-grade performance or who are building around a full Qubic System cockpit.

What cockpits are the QS-210 and QS-220 compatible with?

Both come with bracket sets designed to fit most popular aluminium profile cockpits available on the market including 8020, 4040 and similar profiles. They can also be configured with the dedicated Qubic System cockpit profiles used in the QS-V20 and QS-S25. If you are unsure whether your existing rig is compatible, contact us with your cockpit model and we will confirm before you order.

Can I expand my system later?

Yes. Qubic System is designed to be modular. The QS-CH2 can be expanded to 5DOF by adding a QS-210 or QS-220 3DOF actuator set. One QS-MC6 controller manages up to four actuator sets, so you do not need to replace any existing hardware when expanding. The QS-BT1 belt tensioner can also be added to any existing Qubic setup for an additional layer of immersion.

Where do Qubic System products ship from and how long does delivery take?

All Qubic System products are manufactured in Poland and ship directly from the Qubic System facility. Delivery to UK mainland addresses takes 1 to 2 weeks from dispatch. Free UK mainland delivery is included. The QS-H13 seat mover has a separate lead time — contact us to confirm availability before ordering.

What warranty do Qubic System products come with?

All Qubic System products come with a 2 year warranty for personal use and a 1 year warranty for commercial use, covering manufacturing defects. Post-sale technical support is provided directly by Qubic System via support.motionsystems.eu.

What is the QS-BT1 and how does it differ from a motion platform?

The QS-BT1 is a dual-channel direct drive seat belt tensioner. Instead of moving the whole platform or seat, it physically tightens your harness in response to braking, cornering and G-forces detected from game telemetry. It can be used as a standalone immersion device or alongside any Qubic System motion platform. It uses the same direct drive technology as the QS-220 actuators and delivers 200N of force per channel.
