Belt Tensioner QS-BT1

QS-BT1 Belt Tensioner: Real G-force sensations in your simulator

The Qubic System QS-BT1 is an innovative belt tensioning system designed to take simracing immersion to a whole new level. Thanks to its dual-channel direct drive technology, this device reproduces physical forces on your body, realistically simulating braking, acceleration, and G-forces.

It's the ideal complement for those seeking a professional racing simulator experience with advanced physical feedback.

Key advantages that make the difference

• Real G-force simulation directly on the body
• 200N of force per channel for intense and precise sensations
• Perfect complement for motion systems
• Also works independently
• Total immersive experience in simracing and aerial simulation

Key features of the QS-BT1

• Type: Dual-channel belt tensioner
• Force: 200N per channel (≈20.5 kg)
• Power: ~321W
• Channels: 2 independent
• Connectivity: USB (PC)
• Lighting: Configurable RGB
• Compatibility: Motion platforms QS, PS, HS and standard cockpits
• Software: Integration with Qubic ecosystem

Real sensations beyond motion

The QS-BT1 adds a dimension that even motion systems cannot fully replicate: direct pressure on the body.

It allows you to feel:

• Intense braking (forward pressure)
• Accelerations and lateral G-forces
• Loss of traction and oversteer
• Gear changes and engine vibrations

This creates a much more natural connection with the car, improving both immersion and control.

Designed for advanced setups

The QS-BT1 can be used in several ways:

• As a complement to motion platforms (QS-210 / QS-220)
• As an independent device to add physical feedback
• Integrated into professional or home setups

In addition, its silent operation makes it ideal for long or endurance sessions.

Compatibility and requirements
