What Is FFT-GYRO
FFT-GYRO is a first-flight tester gyroscope that supports the drone at the center while allowing meaningful roll, pitch, and yaw motion inside a secure structure.
Its adjustable geometry helps align the drone center of rotation with the gyroscope, supports different multirotor sizes and types, and can be installed in open or closed spaces.
The FFT GYRO is a specialized gyroscope that can move freely in the roll, pitch, and yaw axis without any limitation, while supporting a drone in the center. Its safe structure allows the system to be installed in an open or closed space and interact with people in real time. With its adjustable height for different multi-rotors, the center of rotation of the drone can be aligned with the center of rotation of the gyroscope allowing the drone to rotate about it’s true center of rotation. It can hold different types and sizes of multi-rotors, from small racing drones to big industrial drones.
The FFT-GYRO is essentially useful for everyone that works with drones or UAVs. From beginner users that want to learn how to fly, to drone development companies that want to keep leading the market. It comes out as a solution for a wide variety of problems that are very common in this field. The FFT GYRO is not only a tool for research and development. It is the tool that makes easy to work with drones and helps to stay ahead of the game.
Roll, pitch, and yaw are organized so the aircraft can be observed under thrust without leaving the frame.

Diferent Gimbal Configurations
the system G3.5 keeps Roll → Pitch → Yaw and the system G4.0 moves Yaw first, which changes inertia, response feel, and the mounting approach around the drone.
Roll-first architecture with direct AHRS-aligned measurement logic and a hollow center for hardware clearance.
It favors conventional measurement logic and gives more open volume around the aircraft center.
You want the published Roll → Pitch → Yaw stack and hardware clearance is a priority.
Yaw-first architecture with lower yaw-driven inertia and a response profile that feels closer to free-flight behavior during maneuver work.
It shifts the inertia profile and makes the stand react more naturally during demanding dynamic tests.
You want the published Yaw → Roll → Pitch stack and better maneuver-response fidelity.
The full published table remains available here for deeper technical review.
| Feature / Version | G3.5 | G4.0 |
|---|---|---|
| Angle measurements | Follows the AHRS convention and takes direct measurements. | Does not follow AHRS directly and uses processed measurements. |
| Free channels for custom connection | Yes | No |
| Gimbal inertia | Fixed and stable inertia. | Reduced, but variable inertia. |
| Drone maneuverability | Yaw gimbal adds considerable inertia and affects maneuverability. | Better responsiveness for maneuver testing with near-real flight behavior. |
| Drone mount type | Hollow center with room for batteries, landing gear, payload, and other hardware. | Base plate mount that is easily interchangeable for customizations. |
Sizes / How To Choose
Start with the drone envelope. Rotor-to-rotor distance sets the shortlist, and outer diameter confirms the clearance the frame must preserve.
Use the main prop-center span to identify the correct FFT-GYRO family first.
Confirm the full aircraft envelope, including landing gear, payloads, and mounted hardware.
Avoid oversizing unless the total installed envelope truly requires a larger structure.
Use rotor-to-rotor distance and outer frame diameter together when you need the exact published range check.
| Spec / Size | 250 | 450 | 600 | 800 | 1000 | 1200 | 1500 | 2000 |
|---|---|---|---|---|---|---|---|---|
| Rotor-to-rotor distance (mm) | 100 - 250 | 250 - 450 | 450 - 600 | 600 - 800 | 800 - 1000 | 1000 - 1200 | 1200 - 1500 | 1500 - 2000 |
| Outer diameter (mm) | Up to 450 | Up to 750 | Up to 950 | Up to 1200 | Up to 1450 | Up to 1750 | Up to 2150 | Up to 2750 |
Software Ecosystem
FFT-GYRO is more than a structure. The platform can stay mechanical and containment-focused in Standard form, or move deeper into measurement and software-driven workflows in Pro form.
Add-Ons / Expandability
Motor kits turn FFT-GYRO into an active test system: size determines compatibility, and torque family tells you how much commanded force each axis can deliver.
Compatibility is published by platform size and shows where active torque modules can be added.
| Spec / Size | 250 | 450 | 600 | 800 | 1000 | 1200 | 1500 | 2000 |
|---|---|---|---|---|---|---|---|---|
| Motor kit compatibility | 1.4 and up | 3.0 and up | 4.1 and up | 7.3 and up | No | No | No | No |
Rated torque shows the continuous actuation level. Stall torque shows the peak holding limit of each kit family.
| Spec / Motor Kit | Motor Kit 1.4 | Motor Kit 3.0 | Motor Kit 4.1 | Motor Kit 7.3 | Motor Kit 10.6 |
|---|---|---|---|---|---|
| Rated torque (Nm) | 0.28 | 0.6 | 0.82 | 1.46 | 2.12 |
| Stall torque (Nm) | 1.4 | 3.0 | 4.1 | 7.3 | 10.6 |
