Swallow VTOL vs. professional quadcopters: which is the strategic choice for your business?

In recent months, Aerialclick has introduced an important new product to the world of professional drones: the Swallow VTOL. Thanks to its hybrid configuration, this drone can take off and land vertically even in tight spaces, then transition to fixed-wing flight. A solution that combines agility and versatility with high efficiency in horizontal flight.

To help professionals choose the drone best suited to their operational needs, it can be useful to compare this platform with one of the market's flagship quadcopters: the new DJI Matrice 4.

These are two different approaches to the same need: getting sensors and instruments airborne safely, precisely and efficiently. Comparing a VTOL with a quadcopter makes it easier to assess which technology best meets your specific operating conditions and mission objectives.

Applications and cameras

Both drones offer remarkable application versatility.

The Swallow VTOL, thanks to its Plug & Play system, supports a wide range of sensors for a multitude of application fields:​

• Photogrammetry: 26 MP, 42 MP and 61 MP optical cameras.​
• Agriculture 4.0: multispectral cameras such as Micasense Altum PT and Sentera 4X.​
• Thermography: 640×512 px thermal camera.​
• Security and surveillance: support for different types of trackers, used for monitoring critical infrastructure, surveillance of large areas, territorial control, and search and rescue operations.

The DJI Matrice 4 is available in the 4T and 4E versions, each designed to offer versatility and precision in aerial operations in specific fields of application:

• The 4T version is equipped with a 1/1.3-inch CMOS wide-angle camera with 48 MP, a 48 MP medium camera and a 48 MP telephoto lens, as well as an infrared thermal camera with 640×512 resolution.
• The 4E version, on the other hand, features a 4/3-inch CMOS wide-angle camera with 20 MP, a 48 MP medium camera and a 48 MP telephoto lens. This multi-sensor configuration allows the Matrice 4 to carry out detailed inspections, monitoring and search and rescue operations with high precision.

Flight time

The Swallow VTOL is equipped with a 27,000 mAh Li-ion battery, which provides a flight time of approximately 2 hours without needing to land. At the end of the mission, the battery replacement is quick thanks to the easily accessible compartment, allowing a new takeoff in an extremely short time.

The DJI Matrice 4, on the other hand, uses a 6,741 mAh battery, which guarantees a flight time of approximately 46 minutes. Here too, quick replacement is possible, allowing operations to resume shortly after landing.

A key factor to consider is operating speed: the Swallow VTOL can fly at an average speed of 22 m/s, higher than what the Matrice 4 can achieve, which can reach similar values only in no-wind and optimal conditions. This makes the Swallow particularly suitable for covering large areas in a short time, benefiting the overall efficiency of the mission.

Structure and materials

The construction of the two drones also reflects their respective operational purposes.

The Swallow VTOL is made of Kevlar and carbon fiber, composite materials known for their high strength-to-weight ratio. This choice keeps the drone's mass to a minimum without compromising its robustness, making it suitable for long-duration missions and demanding operating conditions, even in critical scenarios or exposed environments.

The DJI Matrice 4, on the other hand, adopts a structure made of high-quality plastic materials, designed to ensure solidity and reliability in standard operations. It is an effective solution for intensive professional use, while still maintaining good impact resistance and adequate thermal management of the internal components.

Data transmission

The DJI Matrice 4 comes with the DJI RC Plus 2 Enterprise Enhanced remote controller, which allows a maximum range of about 25 km in ideal conditions. It is a stable, reliable system compatible with the DJI Enterprise ecosystem, designed to ensure high performance even on complex missions.

The Swallow VTOL, on the other hand, uses the H16 Pro Smart Remote Control smart controller, which offers a maximum range of 30 km. In addition to the greater theoretical distance covered, this system is designed to offer high signal stability even in environments with interference, thanks to support for multiple frequencies and advanced transmission technologies.

Conclusions

Both drones are top-of-the-range solutions, each designed to meet different operational needs, dictated mainly by their configuration and structure.

The Swallow VTOL is particularly well suited for mapping and surveillance of very large or hard-to-reach areas, thanks to its long flight endurance and higher operating speed. It is also more versatile in the context of agriculture 4.0, as it can integrate various multispectral cameras — an area in which the DJI Matrice 4, which currently has no variant with integrated multispectral sensors, is less suitable.

On the other hand, for operations in confined environments, requiring precise maneuvers and takeoff/landing in tight spaces, the Matrice 4 may be the more functional choice, thanks to its compact quadcopter configuration and the great operational reliability typical of the DJI ecosystem.

In conclusion, the choice between the two systems depends on an analysis of operational needs.
