Qubic System QS-BT1 Direct Drive Seat Belt Tensioner with Optional Trak Racer Seat Harness
QS-BT1 Dual-Channel Seatbelt Tensioner
Product Overview
The Trak Racer QS-BT1 is a high-performance dual-channel seatbelt tensioner engineered to simulate the real-world forces experienced in motorsport and aviation. From heavy braking and cornering G-forces to engine vibration and gear shifts, the QS-BT1 delivers responsive, immersive feedback that motion platforms alone can't match. Built for sim racing and flight sim enthusiasts who demand uncompromising realism.
Key Features
-
Dual 200 N direct-drive motors (400 N combined force)
-
Seamless integration with all Trak Racer and Motion Systems–powered platforms
-
Compatible with racing sims, flight sims, and open-source WindSim projects
-
Simulates braking, lateral Gs, gear shifts, road texture, and more
-
Offers unmatched realism in sustained forces, gear transitions, and vehicle behaviour
-
Advanced safety features including dual-channel self-test and Motion-Lock compatibility
Technical Specifications
| Specification | Detail |
|---|---|
| Force per channel | 200 N (20.5 kg / 45 lbs) |
| Combined maximum force | 400 N (41 kg / 90 lbs) |
| System type | Dual-channel, direct-drive belt tensioning |
| Compatibility | QS / PS / HS motion platforms, standalone, WindSim |
| Use case | Sim racing, flight sim, training, and experimental builds |
| Safety | Motion-Lock circuit compatible, dual-voltage motor logic |
Immersive Simulation Features
Braking Feedback
Experience the full weight of braking forces as the QS-BT1 dynamically tightens the seatbelt, giving physical feedback that mirrors real-world deceleration.
Advanced Steering Feedback
Dual voltage channels provide precise force during high-G cornering. The QS-BT1 reacts in real time, simulating lateral overloads as you hold a racing line or fight for control mid-drift.
Engine & Road Vibration
Feel engine pulses, kerb strikes, and shifting road textures through your harness. The QS-BT1 accurately reproduces surface changes and power delivery across supported titles.
Gear Shift Realism
Each gear change triggers a responsive belt tug, simulating the shift jolt experienced in high-performance vehicles.
Cornering G-Forces
As you swing through fast turns, the QS-BT1 simulates centrifugal force by adjusting seatbelt pressure, helping you intuitively feel the apex load.
Flight Simulator Integration
Supports G-force simulation across vertical and lateral axes. Simulates positive/negative Gs, weapon recoil, flare deployment, and throttle transitions with precision.
Why It Matters
Motion platforms excel at short-burst effects but struggle with sustained Gs. Even high-end 6DOF setups can’t match the prolonged physical load of a 200 N channelled system like the QS-BT1. By combining the two, you unlock layered realism: your motion platform handles the dynamic movements, and the QS-BT1 delivers the sustained physical forces your body expects.
