PDK Ecosystem · RSCV021
Six motors move the platform directly. Air carries the weight, so the motors spend their whole budget on motion instead of holding you up.
The whole rig, wheel and pedals included. You add the seat, PC and screen.

The architecture
A Stewart platform puts six actuators between a fixed base and a moving top, so every leg contributes to every motion. Ours are driven directly — no belt to stretch, no gearbox to take up before the platform answers.
Three pneumatic cylinders carry the static load, which is the part covered by patent CA 3217174 C. With gravity handled, the motors only work on the difference between where the platform is and where the trajectory wants it.
Powerful
A 1.41-farad recuperative capacitor bank lets the platform draw 30 kW in a burst — so a hit arrives at full strength instead of being rationed by the supply.
Robust
Three pneumatic pistons with dual dead-volume ballast tanks work in tandem with the motors: the air balances the mass, the motors move it. On a custom cast-aluminium base and table, it carries 250 kg of payload on 115 kg of platform.
Precise
2,097,152 positions per revolution, on every one of the six motors.
On camera
Four people, filmed as they climbed out. Each consented; none was paid or given anything. Every quote is cut from a captioned film on See it move.
Feels absolutely amazing … very realistic, especially the jumps.
Bruno BlumbergsRallycross driver · SimRacing Expo, Dortmund 2025
It felt stable … there was a lot more verticality than I thought there would be.
Jake RupertDriver · seated in the PDK Racer at the expo
Like nothing else … I’ve been sitting in motion rigs like that, but never driving, really. Really is a whole different beast.
Expo attendeeSimRacing Expo, Dortmund 2025 · minutes after a run
That was a workout … really good bit of kit.

Envelope
Surge, sway and heave move the platform along three axes. Pitch, roll and yaw turn it about them. The firmware refuses a pose outside its limits rather than quietly clamping it.
