Why is there no overall gain slider
for QS-BT1?

There is no “overall gain” slider for QS-BT1 because this is not the best way of tuning the device’s operation. We want to encourage you to discover what QS-BT1 can really do and adjust its operation to your preferences. We are aware that there is an “overall” slider for motion platforms, but it is mainly for sim racing centers and should never be used as a tool for settings adjustments, even if it is tempting.

What is unique in QS-BT1 is that you feel the feedback on your body (mainly shoulders), and there are many components between the motors and your shoulders that might affect what you feel. The shape and material of the seat slots, fitment of the low-friction inserts, belt’s weight, your body type (skinny or muscular), type of seat belts, and how much the seat belt moves up/down around your waist — everything matters and affects the experience. Basically, no two identical setups exist in the world.

The experience with QS-BT1 consists of many different components, and the Braking effect is the dominant one. If you feel that the QS-BT1 is initially too strong – firstly reduce the Braking force. After that reduce Gear Change Intensity, and you’ll find that QS-BT1 is no longer too strong.

If you really wish to discover what QS-BT1 can do, a little more work is needed. You should disable all effects and adjust them one by one while test driving. After that, turn on all effects together and adjust them again so the feedback feels balanced and not overpowered.

These two components are similar, yet they are different. We suggest you check each of them separately and also both together as a tandem. Different games calculate sideways acceleration (a.k.a. lateral acceleration) differently, so you should always check with a specific game. Sideways acceleration is present when you start to turn or hit something sideways (e.g. an opponent vehicle). Its value is often close to zero in long corners.

Centrifugal force, on the the hand, usually happens after Sideways acceleration, in turns — especially long turns — and, as the name suggests, it is the centrifugal force that acts on the vehicle.

In most cases, road harshness telemetry comes from the vehicle’s suspension telemetry and allows you to feel the road, via slight heave motion. It increases immersion in road racing but might generate too much noise in rally. Vertical G-Force, on the other hand, uses vehicle’s vertical acceleration and simulates sudden elevation changes really well. Therefore, it is better for rally but not so much for track racing. Of course, a combination of both can be great, but you need to find the parameters that suit you best.

Sideslip generates subtle vibrations when the rear of the vehicle starts to oversteer, powerslide, or drift. Our experience shows that vibrations are more noticeable than force cut-off (belts suddenly becoming loose to imitate the loss of grip which causes momentary feeling of inertia). However, you can configure it to cut off all forces if this is what you prefer.

Wheel Slip Angle is a more advanced version of Sideslip, as it calculates slip per wheel but needs a few additional parameters (which depend on the specific vehicle) for precise calculation. You’ll find them in Vehicle Parameters tab. When configured correctly, this effect will indicate oversteer, powerslide, drift, but also understeer. Sideslip works fine in road races and rally; Wheel Slip Angle is recommended only for road racing, as in rally it might generate too much noise.
