DJI AVATA 2, la VERITA' su FCC e SBLOCCO VELOCITA'

Summary

The video script discusses the Avata 2 drone's radio signal, focusing on its unlocking features, speed, and FCC regulations. The Avata 2 operates on 5.8 GHz for video signal transmission, while the radio control and Motion controller signals use 2.4 GHz. It also utilizes the new O3 Air Unit protocol and can fly on three bands, depending on the location. In Europe, it uses 2.4 GHz and 5.2 GHz (referred to as 5.1 GHz in some regions), with a power output of 200 mW or 23 dBm. The video compares the performance of Avata 2 in Europe (CE mode) to its performance in the US (FCC mode), noting that the CE mode is quite efficient and not significantly different from FCC mode. The script also touches on the limitations imposed by DJI's firmware in Europe, the need for official U-space geographic zones, and the transmission of electronic identification and telemetry data. It concludes by mentioning that while the Avata 2's speed can be unlocked in certain modes, exceeding 19 m/s (68.4 km/h) is not compliant with standard scenarios, suggesting the use of the drone for specific operations with authorization.

Takeaways

• 📺 The video is an informative tutorial about the Avata 2 drone, its radio signal, speed, and FCC-related matters.
• 🌐 Avata 2 operates solely on the 5.8 GHz frequency, unlike its predecessor which used 2.4 GHz for radio control and motion controller signals.
• 🎥 Avata 2 uses the new OcuSync 4 protocol, offering improved performance over the previous OcuSync 3 used by Avata.
• 🏙️ In Europe, Avata 2 uses 2.4 GHz and 5.2 GHz (referred to as 5.1 GHz), while in the United States, it uses 2.4 GHz and 5.8 GHz.
• 🚫 The current DJI firmware has locked the automatic transmission mode in Europe, requiring pilots to use official safety zones for flight.
• 🗺️ Italy has not yet provided official geographic zone files for drones, unlike other countries such as France and Luxembourg.
• 💡 The drone's compass indicates the geographical North direction, which is essential for operating within specific geographic zones.
• 🚫 The free AM Config system from the Goggle 2 and Avata 1 does not work on Avata 2 without the modified DroneTwix app.
• 🔓 With the DroneTwix app, FCC mode is enabled, and more telemetry data channels become available, although it is a paid app.
• 🏎️ Avata 2's C mode performs well, with only a slight difference in efficiency compared to FCC mode, and it is roughly equivalent to Avata 1's FCC mode.
• 📈 Even in C mode, Avata 2 sometimes exceeds the 19 m/s speed limit, which might be due to firmware bugs that could be resolved in future updates.

Q & A

What is the main difference between Avata 2 and its predecessor in terms of radio signals?

The main difference is that Avata 2, unlike its predecessor, operates on three frequency bands: 2.4 GHz, 5.2 GHz (referred to as 5.1 GHz in the script), and 5.8 GHz, depending on the location of flight.

Which frequency bands does Avata 2 use when flying in Europe?

When flying in Europe, Avata 2 uses the 2.4 GHz and 5.2 GHz (or 5.1 GHz as mentioned in the script) frequency bands.

What is the power output of Avata 2 when operating on the 5.2 GHz band?

The power output of Avata 2 on the 5.2 GHz band is 200 mW, which is equivalent to 23 dBm.

Why is the automatic transmission mode locked in the current DJI firmware when Avata 2 is flying in Europe?

The automatic transmission mode is locked because the current DJI firmware does not allow manual changes, and there is no option to switch to manual mode as seen in the script.

What is the issue with the official U-space geozones in Italy?

The issue is that Italy has not yet allowed the uploading of official U-space geozone files to the drone, which other countries like France and Luxembourg have already implemented.

What does the compass at the bottom of the screen indicate when Avata 2 is flying?

The compass at the bottom of the screen indicates the geographical direction of North and is used when entering a geographical area, showing the drone's direction.

How does Avata 2's CE mode compare to its FCC mode in terms of performance?

The CE mode of Avata 2 is quite efficient and there is not much difference compared to the FCC mode. The OCUS 4 protocol and the automatic switch between 2.4 GHz and 5.2 GHz make the CE mode perform very well, even when compared to the FCC mode.

What is the free AM Config system and why does it not work on Avata 2 without modifications?

The free AM Config system is a feature that works on goggles 2 and Avata 1. It does not work on Avata 2 until the user applies the modified DJI app called Drone Twix, which is a paid app that enables FCC mode.

What is the maximum number of channels available with AM Config when using Drone Twix on Avata 2?

With Drone Twix and AM Config, there are three channels available on 60 MHz, which is the maximum allowed in Europe.

What happens to the FCC mode when a normal, unmodified DJI Fly is connected to Avata 2?

When a normal, unmodified DJI Fly is connected to Avata 2, the FCC mode is eliminated, and the drone operates without it.

What is the maximum speed that Avata 2 can achieve in CE mode?

In CE mode, Avata 2 is not supposed to exceed a speed of 19 m/s, which is approximately 68.4 km/h.

What is the current limitation in Europe regarding the use of Avata 2 in standard scenarios?

In standard scenarios in Europe, there is a speed limitation of 5 m/s, and Avata 2 can be used with specific operational authorization.
