The Qubic System QS-BT1 is a dual-channel direct drive belt tensioner for sim racing, compatible with PC, generating 200 N of force per channel to physically reproduce the G-forces of braking, acceleration and traction loss on your body.

Based on the same direct drive technology as the QS-220 actuators, the QS-BT1 tightens the belt in real time according to the game telemetry, adding a layer of immersion that even motion systems can't reproduce: direct pressure on your body. It works as an add-on to a motion platform or as a standalone device, and is managed with Qubic Manager / ForceSeatPM, compatible with most sims.

Key features of the Qubic System QS-BT1

Dual-channel direct drive with 200 N of force per channel (400 N combined) for intense, precise sensations.
Reproduces braking, acceleration, lateral G-forces, traction loss and gear changes directly on your body.
Same direct drive technology as the QS-220 actuators, with fast response and quiet operation.
Works as an add-on to a motion platform or as a fully standalone device.
Configurable RGB lighting and ~321 W of power.
Also suitable for flight simulation: reproduces G-forces during high-load manoeuvres.
Integration with Qubic Manager / ForceSeatPM and mounting on aluminium cockpits with included universal adapters.

Does it include the harness and seat?

No. It requires a compatible racing seat and harness, which are not included. The universal mounting adapters are included.

Is it compatible with consoles?

No. It works on PC (Windows) via Qubic Manager / ForceSeatPM.

Is it suitable for flight simulation?

Yes. Besides sim racing, it reproduces the G-forces of flight manoeuvres.
