Built for how
you'll use it.
Four builds on one direct-drive core, one patented weight-compensation system, six axes. What differs is how much of the rig around it we build for you.

Before you order
- Where we ship today — ordering is open for the United States, the European Union and the rest of the world. EU orders are priced in euros with VAT and import duty included; everywhere outside the EU, in US dollars. The region you choose sets the price and the tax basis.
- Who you buy from — it depends on where it ships. To the United States and the rest of the world: ARK Dynamics Global, a Wyoming corporation, in USD. To the EU: ARKINEMATICS LIMITED, a Cyprus company, in euros, with VAT and import duty included. ARKINEMATICS is also our EU authorised representative for product safety and our EU data-protection representative. Your seller and your total are named on your order confirmation.
- When it is ready — expected 3 to 6 months from order confirmation; delays of up to 12 months beyond that are possible. We prioritise the PDK + ARK Ecosystem for manufacture, after grid-position holders, whose kits ship first; the window is the same for every kit. Paid in full at order.
- Return carriage — on a 14-day consumer return you pay the carriage to our US return address, about USD 500 by sea, and more from remote addresses.
- Paying over time — where available, you can pay monthly with Klarna, offered at checkout. Approval is theirs, not ours, and the order is placed only once they accept the payment. Whether Klarna is offered depends on your country, so it will not appear everywhere.

Competitor figures from each maker's own website, 24–25 September 2026. Competitor A's price excludes import duty and VAT outside the EU; Competitor B's are ex-VAT and ex-works. Competitor C publishes no price: the range is as reported in the motoring press in May 2024 for its automotive simulators. It states its latency without naming where it is measured from and to. Travel is the total on each axis; where a maker publishes ± limits, the two are added. Competitors A and B, like the PDK, include no seat; Competitor C is delivered turnkey with a vehicle cockpit.
Before you decide
What you are agreeing to, in plain terms.
Do I need to assemble it?
Yes. The kit arrives as pre-assembled modules in six to nine boxes depending on the build, none over 26 kg, and bolts together in fourteen steps, feet first. One person can do it. The Safety Manual and Installation Guide ship with the kit; the Kinemaniacs community site, where owners will share build notes and tuning profiles, is in development.
When does it ship?
Expected 3 to 6 months from order confirmation. Delays of up to 12 months beyond that are possible. We prioritise the PDK + ARK Ecosystem for manufacture, after grid-position holders, whose kits ship first; the window is the same for every kit. You can cancel for a full refund at any time before dispatch.
Who is my contract with?
Delivery to the USA and the rest of the world is contracted by ARK Dynamics Global (Wyoming), in USD. Delivery to the EU is contracted by ARKINEMATICS LIMITED (Cyprus), in euros, with VAT and import duty included. ARKINEMATICS is also our EU authorised representative for product safety and our EU data-protection representative.
What does the patent cover?
Adjustments to the Stewart platform that separate weight-bearing from positioning: a pneumatic actuator carries the load and a direct-drive actuator does the moving. Canadian patent CA 3217174 C, granted 11 February 2025. Read the patent page

Grid-position holders
Your code prices three builds.
Grid positions are no longer sold, and nothing is charged to hold one. If you already have a position we email you a personal code, tied to your email address and usable once. It applies to three builds — the PDK, the PDK + Extension Feet & Table and the PDK + ARK Ecosystem — and entering it in the order card above reprices the build on the spot. The PDK Racer is the one build it cannot move.
With your code: PDK + ARK Ecosystem $5,499.99 · PDK + Extension Feet & Table $3,599.99 · PDK $3,499.99. In the EU: €5,599.99 · €3,699.99 · €3,599.99.
In the box
What's in the box.
Every PDK ships as the complete motion platform. No additional hardware is required to make it move.
Power & control
Drives, the housekeeper and motion-cueing processors, the capacitor bank, the universal-input supply, the onboard router, and all cabling.
Tuning
A browser dashboard served from the platform's own router. Nothing to install, reachable from any device on your network.
The PDK + ARK Ecosystem adds the racing chassis, extension feet and table, wheelbase, wheel, load-cell pedals and button box: up to nine boxes, none over 26 kg. The full component list is on the builds page.
Built for precision
Where motion fidelity is not negotiable.
Feel the kerb texture, not just the kerb
21-bit resolution reproduces surface detail conventional platforms round away. Used for driver training, team development, and by people who can tell the difference.
The complete motion vocabulary of flight
All six axes — fixed-wing, rotary and UAV. Pneumatic weight compensation makes an extended session practical without the motors heating up under a static load.
Motion before the mismatch
Discomfort in immersive work is a timing problem, not an intensity one. From game telemetry to motion, the PDK takes under 1 ms.
Research-grade, citable, patented
Documented encoder resolution, a characterised envelope traceable to the firmware, and a patent number you can look up. Suitable for vestibular, biomechanics and human-factors work.
A platform you can actually get inside
FlyPT Mover and SimHub integration as the usual routes in, with 80+ games supported locally and large communities sharing profiles. Direct CAN access underneath it for your own implementation.
Designed to be embedded
No lock-in. If you are building something the PDK was not designed for, we would like to hear about it.
After it arrives
You're not on your own.
Every kit ships with its Safety Manual and Installation Guide, and the team answers order and build questions directly. Kinemaniacs — the community site where PDK owners will share build notes, tuning profiles and FlyPT Mover configurations — is in development and opens from here.
