What is Drone Gimbal?

When it comes to capturing stunning aerial footage with your drone, the right equipment can make all the difference. In the world of drone technology, one essential component that has gained significant importance is the gimbal.

In this guide, we’ll delve into the world of drone gimbals, exploring what they are, why they matter, and how to choose the right one for your specific needs.

What Is A Drone Gimbal?

A drone gimbal is a critical support system that provides stability to an object, no matter the movement of what it’s attached to. These devices can come as 1-axis, 2-axis, or 3-axis gimbals, with the number of axes directly affecting the stability of the footage.

The more axes a gimbal has, the more brushless motors are at work, resulting in smoother footage. However, it’s important to note that more axes also mean more weight, which can lead to shorter flight times.

Do Drones Need Gimbals?

Drones do not necessarily need gimbals. Gimbals are a luxurious technology best suited for those who have the budget and plan to use their drones for photography, videography, filmmaking, or other applications requiring high-quality footage.

These sophisticated devices automate the stabilization process, allowing users to focus on flying the drone while capturing exceptional content. If you don’t intend to capture footage, a gimbal may not be necessary for your drone.

Types of Drone Gimbals

Most drones with built-in cameras come equipped with gimbals. These gimbals can have different numbers of axes, each offering distinct advantages and drawbacks:

1-Axis Gimbal

Single axis gimbals are lightweight and cost-effective, primarily balancing the tilt motion. While they are less common in drones due to their limited functionality, they can still get the job done for basic stabilization.

2-Axis Gimbal

2-axis gimbals are more versatile, stabilizing both tilt and roll motions. They provide stable, high-quality footage, making them a popular choice for many drones. However, they may suffer from minor yaw (pan) compensation issues, leading to occasional jittery horizontal movements.

3-Axis Gimbal

For drones on the higher end of the price spectrum, 3-axis gimbals are the go-to choice. They provide the smoothest footage by balancing tilt, pan, and roll motions. However, these gimbals are heavier and more expensive, which can affect flight time and overall drone performance.

How Does A Drone Gimbal Work?

Drone gimbals stabilize video in three different axes: pitch, yaw, and roll. Pitch involves the up and down motion of the camera, yaw refers to the side-to-side movement (left to right), and roll rotates the camera to the left or right. Depending on the number of axes in your gimbal, it can balance these motions accordingly.

Components of a Drone Gimbal

A drone gimbal consists of various components working in unison to provide stable footage:

Brushless Motors

Most components in a drone gimbal, including the motors, are designed for specific cameras and sensors. This custom fit ensures the gimbal can balance the camera’s weight perfectly, resulting in optimal stabilization. Using an off-balance camera or gimbal could lead to drone damage and reduced flight times.

Camera and Sensor

The camera is a crucial part of the gimbal, with the gimbal having the necessary screws, cables, and mounts to secure it in place. A compatible camera-sensor combination is vital for effective operation.

Damping Anti-Vibration Absorber

Damping anti-vibration absorbers reduce high-frequency vibrations from the drone while allowing low-frequency board movements. These components ensure stable footage even in the face of vibrations.

Gimbal Control Unit (GCU)

The GCU is a small computer that collects data from the gyroscope and adjusts the gimbal motors to position the camera correctly. It communicates with the drone’s flight control system and transmits video data for monitoring.

Inertial Measurement Unit (IMU)

The IMU is a built-in component in most drone gimbals, making stabilization virtually automatic. It uses accelerometers and gyroscopes to measure force, angular rate, and magnetic fields, allowing precise tracking of the drone’s position.

Gimbal vs. Steadicam

Gimbals and Steadicams serve the same purpose of stabilizing footage, but they operate differently. Steadicams require a trained operator wearing a vest, using springs to maintain stability. In contrast, gimbals rely on specialized computers with IMUs and motors to stabilize footage automatically. The choice between the two depends on the specific needs and preferences of the user.

How to Choose the Right Gimbal for Your Drone

Selecting the right gimbal for your drone is crucial for achieving the best results. Drones on the higher end of the price range often come with high-quality cameras and gimbals tailored to the drone model. However, if you plan to buy a gimbal separately, consider the following factors:

Amount of Axes

Determine whether you need a 2-axis or 3-axis gimbal. While 3-axis gimbals provide smoother footage, 2-axis gimbals are lighter, offering longer flight times and are often more affordable.

Camera Support

Ensure that the gimbal you choose is compatible with your camera. Many gimbals are designed for specific camera models, and using a universal gimbal may not yield the same results.

Pre-Calibration

Consider whether the gimbal comes pre-calibrated, especially if you’re a beginner. Pre-calibrated gimbals are easier to set up and use.

Gimbal Weight

The weight of the gimbal can significantly impact your drone’s flight time. Make sure to choose a gimbal that balances weight and features to optimize your drone’s performance.

Gimbal Payload

If you plan to use a larger camera with your gimbal, check the gimbal’s payload capacity. This is essential to ensure stability and performance.

Additional Features

Look for gimbals with remote control integration, allowing you to control the gimbal from your drone controller. Some gimbals also offer easy-to-release systems for quickly attaching and detaching your camera.

How Much Does a Drone Gimbal Cost?

The price of drone gimbals can vary widely depending on their quality and features. Industry-leading companies like DJI offer gimbals that come with cameras, and these tend to be on the more expensive side. Lower-cost gimbals, which may not offer the same quality, can be found for around $100 or less.

If you opt for a gimbal with a camera included, be prepared to invest more, with prices starting at $1,000 and going up for high-quality options. Gimbals with more axes will generally cost more due to their enhanced capabilities.

Why Are Gimbals So Expensive?

Gimbals are relatively expensive due to their innovative technology and widespread demand for high-quality aerial footage. While they were once primarily used by professional filmmakers, they have become more accessible and user-friendly, with the added benefit of automation. As technology has advanced, gimbals have become a staple for those looking to capture professional-grade stable footage.

Where to Find a Drone Gimbal

Conclusion

In the world of drone technology, gimbals have revolutionized the way we capture aerial footage. They have not only enhanced the quality of content but have also made it accessible to a broader audience. As drone technology continues to evolve, the demand for drone gimbals will only increase. If you’re considering using your drone for photography and have the budget to spare, investing in a gimbal is a wise choice. The stability and professional-grade footage it provides are worth every penny.
