Qubic System Mount for QS-BT1 installs the belt tensioner on a supported motion platform or cockpit without modifying its structure. Four variants are available: QS-CH1, QS-V20, QS-S25 and NLR Motion Platform V3. Each kit uses different brackets and hardware, so the option must match the installed rig. The Qubic System QS-BT1 belt tensioner is not included.

1. What is the Qubic System Mount for QS-BT1 used for?
It is a dedicated bracket kit for installing the QS-BT1 belt tensioner on one of four supported rigs.
2. Which mounting variants are available?
Separate versions are offered for the QS-CH1, QS-V20, QS-S25 and Next Level Racing Motion Platform V3.
3. Does one variant fit all four platforms?
No. Each version has different geometry and contents. Select the exact variant made for the installed rig.
4. Is the QS-BT1 belt tensioner included?
No. The product contains only the selected mounting kit. The QS-BT1, harness, cockpit and motion platform are sold separately.
5. Does the QS-CH1 version work with QS-210 and QS-220 actuators?
Yes. The brackets fit at the rear QS-210 or QS-220 actuator mounts used on the QS-CH1 cockpit.
6. Where is the QS-BT1 installed on NLR Motion Platform V3?
On the moving upper frame, between the platform and the seat mount or sliders. It must not be fixed to a stationary cockpit section.
7. Can the Buttkicker Gamer 2 bracket be used with the NLR MPV3 version?
No. Qubic System explicitly prohibits use of the standard Buttkicker Gamer 2 bracket for this installation.
8. Does a QS-BT1 change the NLR Motion Platform V3 user-weight limit?
Yes. Once the QS-BT1 is installed, the maximum user weight for this platform is 115 kg.
9. How tightly should the QS-BT1 be attached to its bracket?
The M8 x 40 DIN 913 screws entering the tensioner must be tightened to no more than 10 Nm.
10. Does the kit fit a standard aluminium-profile cockpit?
Do not assume that it does. A standard profile cockpit uses the universal adapters supplied with the QS-BT1 rather than one of the four variants described here.
