QS-BT1 Seat Belt Tensioner for Sim Racing & Flight Simulators

If you're serious about sim racing realism, the QS-BT1 Belt Tensioner is one of the most powerful upgrades you can add to your setup.

Instead of only feeling feedback through the steering wheel, the QS-BT1 physically tightens and releases your harness based on real-time game telemetry, simulating forces like braking, acceleration, cornering, and traction loss.

The result?

A much deeper connection between you and the simulation — making every lap more intense, immersive, and realistic.

Feel Real Racing Forces in Your Simulator

The QS-BT1 was designed to simulate the physical forces experienced by real drivers.

When you hit the brakes hard, the harness tightens around your chest.
When you accelerate, the tension eases.
When you take corners at high speed, the system recreates lateral G-forces.

This creates a powerful illusion of motion and weight transfer, even if your rig doesn't have a motion platform.

Advanced Dual Channel Direct Drive Technology

Unlike traditional vibration devices, the QS-BT1 uses a dual-channel direct drive system.

This allows the device to independently control the tension of each belt, delivering:

• Realistic braking feedback

• Lateral G-force simulation

• High-speed cornering feedback

• Wheel lock sensations

• Traction loss detection

• Road surface feedback like rumble strips

This precision control makes your simulator feel closer to real motorsport than ever before.

Powerful 200N Force Per Channel

The QS-BT1 is capable of producing 200 Newtons of force per channel, delivering strong and immediate feedback to the driver.

That means:

• Strong braking simulation

• Realistic G-force pressure

• Clear driving feedback

• Better immersion and control

This level of force helps simulate the physical sensations that real drivers feel inside a race car.

Works With Sim Racing & Flight Simulators

Although designed mainly for sim racing, the QS-BT1 is also widely used in flight simulators.

It can simulate:

• Positive & negative G-forces

• High-G maneuvers

• Banking and roll forces

• Speed brake effects

• Weapon firing vibrations

This makes it a versatile immersion device for both drivers and pilots.

Works Even Without a Motion Platform

One of the best things about the QS-BT1 is that it doesn't require a motion rig.

Even on a static sim racing setup, the belt tension system can deliver powerful feedback by reacting to in-game telemetry.

This means you can dramatically upgrade your simulator without investing in a full motion platform.

 Engine Vibration & Road Surface Effects

The QS-BT1 also includes advanced vibration simulation, allowing you to feel:

• Engine vibrations

• Gear shifts

• Road texture

• Rumble strips

• Surface imperfections

These subtle details dramatically increase immersion and realism.
