Meet the PDK
game to motion
peak acceleration
degrees of freedom
encoders, every motor
Play 80+ games through FlyPT Mover and SimHub. They run from iRacing and Assetto Corsa Competizione to Microsoft Flight Simulator and DCS World. The PDK works with Xbox and PlayStation too.
The architecture
A Stewart platform has six legs between a fixed base and a moving top. Every leg helps with every move. Ours are driven directly. No belt stretches, and no gearbox has to take up slack before the platform answers.
Three air cylinders carry the weight. This is the part covered by patent CA 3217174 C. With gravity handled, the motors only move the platform to where the game wants it.
Fast
Bigger rigs are slow, and they drag you back to center. The PDK answers the game in under 1 ms and brings you back below what your inner ear can detect, so all you feel is the car.
Powerful
A 1.41-farad recuperative capacitor bank lets the platform draw 30 kW in a burst. So a hit arrives at full strength. The power supply never has to ration it.
Robust
Three air pistons, each with two ballast tanks, work with the motors. The air balances the weight and the motors move it. It stands on a custom cast-aluminum base and table. It carries 250 kg of payload on 115 kg of platform.
Precise
Each of the six motors reads 2,097,152 positions in every turn.
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 · right after a run
That was a workout … really good bit of kit.

Envelope
Bigger travel is no use if it arrives late and has to be taken back. Surge, sway and heave move the platform along three axes. Pitch, roll and yaw turn it around them. All in under 1 ms.

Every build has the same direct-drive 6DOF (DD6DOF) core. The PDK + ARK Ecosystem adds the chassis, wheelbase, wheel, load-cell pedals and button box. Each part is matched and ARK Approved.
Six axes, 3 g and 250 kg from $4,899.99. No other complete motion platform that publishes all three costs less.
