DOF Reality H4r 4-Axis Motion Platform with Heave (Flight / Universal)
Overview
The DOF Reality H4r is the flight and universal configuration of the H4 chassis. Four axes (Pitch, Roll, Yaw, Heave) tuned for combat aviation, civil flight, and helicopter sim use. Heave delivers the vertical force that turns turbulence, vortex ring state, hard touchdowns, and updrafts into physical sensations rather than just visual cues.
Built since 2014 by DOF Reality in Ukraine, the H4r uses commercial-grade European steel and integrated power drive motors with the Smooth Force Unit (SFU) gearing. Same chassis, motion engine, and software as the H4 racing build, but configured from the factory with HOTAS mount points and universal cockpit geometry instead of wheel-and-pedal.
The H4r is the right pick if you want flight, helicopter, and combined-use motion with vertical g-forces, but want to stay below the H6r 6-axis price tier.
Key Features
- True 4-axis motion (Pitch, Roll, Yaw, Heave). Heave is the differentiator vs every 3DOF flight platform on the market.
- Vertical g-forces for flight sim. Turbulence, hard landings, updrafts, vortex ring state, and rotor wash become physical sensations.
- Universal cockpit geometry. HOTAS mount points, rudder pedal rails, combined sim use out of the box.
- Holds up to 150 kg of pilot plus rig weight on commercial-grade European steel.
- SimRacingStudio license included. Telemetry-driven feedback for flight, racing, and rally sims.
- Klarna and Affirm financing available at checkout.

Shipping and Delivery
DOF Reality consolidates orders into a batch every 2 weeks. Total delivery time is 2 to 4 weeks from order placement to your door, via FedEx (North America) or DHL (rest of world). Two-box shipment (verified): Box 1 is 40 kg / 94 x 38 x 28 cm, Box 2 is 60 kg / 80 x 60 x 30 cm.
Customer pays import duties on delivery. Duty varies by destination; typical US deliveries see import duties billed by the carrier (FedEx in North America, DHL elsewhere) on delivery. Sim Drive does not collect this — it is a separate transaction with the carrier.
Warranty and support. Full 1-year manufacturer warranty included. Sim Drive Performance is your first point of contact for product support and coordinates directly with DOF Reality on warranty claims and escalated technical issues. Extended +1 year warranty available as an upgrade option on request.
