Inertia Motors
A breakthrough in operating. Digital mass and drag mean you can change the feeling of operating for the shot.
For the first time ever, the feeling of weight in the wheels is adjustable. Our patented Inertia Motors inside the wheels create inertia exactly like heavier wheels. And not only that, you can change it between shots to suit the creative needs.
Introducing digital drag. Never before has drag been digital. The Inertia Motors can add selective drag into the wheels. Choose how much you want and save it as a preset.
A joyful operating experience. The sum operating experience between adjustable drag and inertia is groundbreaking. The feedback received from veteran operators is overwhelmingly joyful. Being able to choose how the wheels feel in multiple dimensions has never been possible before.
Adapting to Physics
Our goal was to emulate the feeling of a physical gear head. Learn about how we did it.

Double Radios & hardwire Connection
Communication between operator and camera is integral. We added low-latency, long range, dual-band, dual-link radios.
900 MHz and 2.4 GHz working together. The Inertia Wheels have two radios. Our dedicated uplink runs on the wide-open frequency of 860-920 MHz—skirting by interference on the crowded 2.4 GHz. The downlink for feedback from the camera back to the wheels runs independently at 2.4GHz.
Dedication to low-latency. The dedicated uplink radio ensures there is no pause in the uplink signal to receive a reply—resulting in less latency and a snappier feel. Other wheels with only one radio spend 50% of their time listening for feedback.
Built-in frequency scanner. Scan for interfering signals near your current frequency to find the one with the least activity using the internal frequency scanner.
Built-in hardwire. A dedicated hardwire port is included in the wheels and the receiver. Using a cheap lightweight cable, you can reliably run a wired connection 1000ft+. Not only that, but latency is even further reduced when wired, further improving our already low-latency responsiveness.
Third axis
Creating the perfect shot needs more than just a good pan and tilt. Roll. Focus. Iris. Zoom. Shake?
Intuitive interface. Everything in the wheels is accessible via a simple dashboard and menu system. By clicking in on the knobs you can easily toggle through 6 different assignable functions of control. Color both on the screen and around the knob give you bright visual indicators of both what are you controlling and intensity.
Four assignable buttons sit below the screen. These can control a myriad of functions from camera control, such as run stop, to presets of wheel weight and drag.
Third Axis. Everyone wants to roll the camera, so we’ve provided a Third Axis wheel. Use it either as a classic mounted wheel or, for the quick shot, a simple hand unit.
More dimensions of control. Assign more than just roll to the Third Axis. For MōVI’s with the Freefly API available, control focus, iris or zoom.
Handheld simulation or shake effects. The Inertia Wheels have built-in Effects. Imagine a shot starting out as a handheld chase scene that transitions in shot to a buttery smooth gimbal shot. Or add some selective vibrations in camera to that car scene. And you can assign control over these Effects to the Third Axis to dial the effects up, down, or completely out mid-shot. One person can focus on framing, while the other focuses on the effect.
Design
Wheels redesigned from the physics up. Motors change everything. Better performance. Lower cost. Longer life.
Adding motors saves on cost. We encountered a groundbreaking moment in our R&D where we discovered by adding motors, we could actually reduce our parts lists, save on cost, and improve reliability. The wheels are directly mounted on the motors themselves. This removes the need for shafts, mounting systems, bearings, and a slew of other parts.
Adding motors reduces the need for service. By using the motors to drive the drag system, we remove the need for a physical friction system using pads. This reduces not only the number of parts, but also the need for servicing. Our drag system works without any physical contact, purely driven by the electromagnets in the motors.
Adding motors means quicker setup time. Brass or stainless steel wheels are precious and must always be removed for travel. By no longer using brass for inertia, we create a better operating experience using lightweight, affordable, durable aluminum. Never remove the wheels for travel.
Ultra-high resolution encoders. The inertia system required ultra-high resolution encoders. As an added benefit of this, the Inertia Wheels have >70,000 steps of resolution per rotation, far higher than any other wheels designed for gimbals on the market today.
