MM Simulations PhatBoy 150mm Motion Platform

Stop Playing the Car. Start Feeling It. All of our platforms ship assembled, minus peripheries (wheels, pedals, shifters etc.) An enclosed crate shows up, you open it and take it off the crate right to it's new home.

The MM Simulations PhatBoy 150mm 4DOF Sim Racing Motion Platform is a high-performance motion simulator designed for competitive sim racing and immersive driving. Featuring 150mm of actuator travel, powerful 1kW AC servo motors, heavy-duty construction, and MM Simulations preset tuning profiles, the PhatBoy transforms racing-game telemetry into physical acceleration, braking, weight transfer, cornering, elevation changes, curbs, impacts, and chassis movement you can feel through your entire body.

With 150mm of actuator travel, high-output AC servo motors, a rigid aluminum platform, and MM Simulations-developed tuning profiles, the PhatBoy delivers the acceleration, braking, weight transfer, elevation change, road surface, and chassis movement that conventional static rigs simply cannot reproduce.

When the rear of the car starts getting light, you feel it.

When you stand on the brakes entering a corner, you feel the weight move forward.

When you launch out of the hole, the platform responds.

When you clip a curb, drop a wheel, hit a compression, crest a hill, or transition through a high-speed corner, the simulator communicates that movement through your entire body.

That additional information changes competitive racing.

Instead of relying entirely on visual cues and force feedback through the steering wheel, the PhatBoy gives your body another layer of feedback. With practice, you begin reacting to what the chassis is doing instead of waiting to see it happen on the screen.

Why Choose the PhatBoy?

Many motion systems are designed around compact packaging, limited travel, lighter-duty components, or movement that is intentionally softened to accommodate a broader range of installations.

That isn't what we built.

The PhatBoy was developed around rigidity, usable travel, fast response, serviceability, and delivering a convincing vehicle experience.

150mm of Motion Travel

150mm gives the platform enough physical movement to produce dramatic vehicle dynamics without turning every motion command into an exaggerated amusement-ride effect.

Properly tuned, that travel can communicate:

• Acceleration and deceleration

• Hard braking

• Front-to-rear weight transfer

• Side-to-side weight transfer

• Corner entry and exit

• Suspension compression

• Elevation changes

• Curbs and rumble strips

• Road texture

• Impacts

• Jumps and landings

• Rally terrain

• Loss of stability

• Vehicle rotation and chassis movement

The result isn't simply "more movement."

It is more information.

Built Around Serious Hardware

The PhatBoy uses industrial-style motion components rather than building the entire system around lightweight hobby hardware.

PhatBoy 150mm Specifications

Motion Configuration: 4DOF motion platform
Actuator Travel: 150mm
Ball Screw: 25mm diameter / 10mm lead
Servo Motors: 1kW AC servo motors
Motor Speed: Up to 3,000 RPM normal operating range with higher peak capability
Encoder: 16-bit servo feedback
Maximum Linear Speed: Up to approximately 500+ mm/sec depending on configuration and tuning
Platform Construction: Heavy-duty aluminum structure
Power Requirement: 240V AC

Feel the Weight of the Car

A properly tuned motion simulator shouldn't simply shake.

It should communicate what the virtual vehicle is doing.

During braking, the platform can pitch forward and load your body toward the harness and pedals.

During acceleration, you feel the chassis transition rearward.

Through a long corner, sustained chassis movement helps communicate the loading of the vehicle.

During rapid transitions, the platform changes direction with the car.

In rally, off-road, and high-downforce racing, terrain and elevation changes become dramatically more apparent because the simulator is physically responding to telemetry instead of relying entirely on graphics and steering feedback.

That gives the driver another sensory channel.

Your eyes see the car.

Your hands feel the steering.

Your feet feel the pedals.

The PhatBoy lets your entire body feel the chassis.

Designed for Competitive Racing

Motion isn't only about immersion.

When tuned correctly, it can also become useful feedback.

Drivers can begin recognizing:

• Weight beginning to transfer

• The car becoming unsettled under braking

• Rear-end movement

• Suspension compression

• Corner loading

• Rapid direction changes

• Changes in terrain

• Loss of stability

• Acceleration events

• Impact and curb response

That additional physical feedback can help you develop a stronger connection with the vehicle and react more naturally during competitive driving.

And when you aren't chasing lap times?

Crank it up.

Rally, drifting, off-road racing, trophy trucks, open-wheel cars, stock cars, and high-powered road cars become an entirely different experience when the simulator underneath you actually moves.

MM Simulations Preset Tuning Profiles Included

Hardware is only half of a good motion system.

Tuning matters.

MM Simulations has spent hundreds of hours developing, testing, driving, and refining motion profiles to create responsive movement without simply throwing the simulator around.

Every PhatBoy platform includes our MM Simulations Preset Tuning Profiles for up to four supported racing titles.

These profiles are designed to give you a strong starting point immediately instead of forcing you to spend your first several days learning motion software, axis assignments, filtering, gain settings, limits, telemetry behavior, and tuning from scratch.

Your included profiles are configured during onboarding based on the titles you select.

Want profiles for additional titles?

Additional profiles and custom tuning are available through MM Simulations remote service sessions upon request.
