Review of the Meteor75 PRO DJI O4 – the best 1S TinyWhoop on a digital system?

2025 New Release: Meteor75 PRO with O4 Unit

In this article, we'll try to figure out whether this drone will become a hit of 2025 or a failure. Does a digital video system make sense in a TinyWhoop, or will it fall apart after a few flights? We'll also find out if there's a chance to capture nice cinematic-style videos.

Which Versions Can You Buy?

Let's briefly look at which versions of Meteor75 PRO O4 are available for purchase.

Meteor75 Pro O4 Brushless Whoop (PNP Version)

In this version, you need to connect the O4 unit yourself. This is a good option for those who already have the appropriate video system or enjoy assembling drones themselves.

Package includes:

• 1x Meteor75 Pro O4 (PNP version)
• 1x Dome for O4 Air unit
• 4x Spare GF 45mm 3-blade propellers
• 1x Type-C to SH1.0 adapter
• 1x SH1.0-4Pin adapter cable

The package is quite extensive. We recommend assembling the drone at home under good lighting, as there are many small parts. Additionally, this is not something to rush.

Meteor75 Pro O4 Brushless Whoop (DJI O4 Version)

In this version, the drone is already assembled, which greatly simplifies the process for the user. This is a great option for those who want to take the drone out of the box and fly immediately, as well as for beginners who are just getting familiar with FPV.

Package includes:

• 1x Meteor75 Pro O4 brushless Whoop quadcopter (DJI O4 version)
• 4x Damping balls for DJI O4 camera
• 4x Spare GF 45mm 3-blade propellers

Both versions have their advantages, so the choice depends on your needs and preferences.

New Features in Meteor75 PRO DJI O4

Flight Controller: Matrix 1S 3IN1 HD FC

One of the major updates is the new flight controller. Betafpv previously had models that could fly with the O4 unit, but they had issues: rapid battery drain and unexpected unit shutdowns during flight when throttle was suddenly increased.

In the new version, the manufacturer has eliminated these drawbacks. Now the unit works as long as the drone has sufficient energy for flight. According to tests, the unit shuts down at a voltage of 2.4V-2.3V.

Matrix 1S 3IN1 HD FC is specifically designed for 1S HD Whoop drones. It is created exclusively for FPV operating on a digital video system, as it does not support analog OSD. The controller combines FC, ESC, and ELRS 2.4G RX. Thanks to improved BEC and ESC modules, Matrix 1S 3IN1 HD FC ensures stable power supply to the video system throughout the entire flight.

Motors, Propellers, and Frame

Meteor75 Pro O4 is equipped with 1102-22000KV motors and GF 45mm 3-blade propellers. This combination provides an optimal balance between power and efficiency, allowing pilots to smoothly control the drone and obtain high-quality video using the DJI O4 Air Unit.

According to the manufacturer, the drone, powered by a LAVA 1S 550mAh battery, can fly for approximately 5 minutes and 30 seconds.

Updated Canopy and Frame

The new frame has an increased motor-to-motor distance — 80.8mm compared to 75mm in the standard Meteor75 PRO version.

The canopy is designed to accommodate the camera along with mounting and anti-vibration system. The new design allows adjusting the camera tilt angle from 10° to 30°. This enables both smooth cinematographic flights and high-speed flights with extreme maneuvers.

The update has also significantly reduced sensitivity to vibrations, eliminating the common "jello effect" in videos.

DJI O4 Air Unit Lite Video System Overview

DJI O4 Air Unit Lite is a lightweight version of DJI's digital video system, specifically designed for micro drones. It provides high-quality video with minimal weight, making it an ideal choice for compact FPV drones like TinyWhoop.

Main features of DJI O4 Air Unit Lite:

Maximum resolution: 4K @ 60 frames/s

• Field of view: 117.6°
• Video latency: from 20 ms
• Weight: 8.2 g (with camera)
• Built-in memory: 23 GB (no microSD slot)
• Transmission range: up to 10 km (FCC), up to 6 km (CE)
• VTX power: 50mW, 100mW, 200mW, 400mW, 700mW

Who is DJI O4 Air Unit Lite suitable for?

This video system is perfect for micro drones where minimal weight and compactness are important. It provides quality images with low latency but has limited transmission range and internal memory without expansion capability. If you need better video quality and longer range, consider the Pro version, but it's designed for larger drones and costs significantly more.

• Flight time: up to 5 min 30 sec (with BT2.0 550mAh 1S battery)

Smaller Brother

If you need a smaller drone, the manufacturer offers Meteor65 Pro O4. It's more suitable for indoor flights, such as in houses or hangars, where there's no external influence on the drone's aerodynamics. However, even a light wind can become a serious obstacle for this quadcopter, so comfortable flights outdoors in windy conditions will be impossible.

We won't do a full review, but just compare the specifications in a table.

Conclusions

BetaFPV has really put in the effort. The new controller allows pilots to enjoy a quality picture during TinyWhoop flights. The drone has good characteristics for flights in large indoor spaces, as well as in favorable weather conditions outdoors.

According to rumors online, there are sometimes stabilization issues, especially in open spaces. However, these are likely isolated cases, so there's no need to worry too much. It's important to note that this drone responds more smoothly to throttle and turns during flight, making it more convenient to control, especially for beginners.

Features of the PNP Version Package

For Meteor75 Pro O4 (PNP version), where you need to connect the O4 unit yourself, there's no paper manual included. However, the manufacturer has taken care of this by posting a video tutorial on the official website. Link: BetaFPV Meteor75 Pro O4 PNP.

The drone is equipped with its own stabilization system that handles its task well. Thanks to this, the image remains clear during stunts. However, be prepared that after a fall, a "jello effect" may appear in the video, so it's a good idea to stock up on consumables in advance: frame, canopy, and propellers.

Is It Suitable for Beginners?

If you've just transitioned from a simulator to a real drone, Meteor75 Pro O4 may not be the best choice. The front part of the canopy is quite flexible, and with hard impacts, the camera can touch the VTX. In the case of a strong collision, this can lead to a video transmitter failure. The camera is connected to the board through an adapter, and such connections are often a weak point. Fixing this yourself will be difficult.

Perhaps the problem could be partially solved by securing the connector with non-conductive glue. This would strengthen the camera mount and reduce the risk of breakage.

Flight Time

The manufacturer claims that the flight time is up to 5 minutes and 30 seconds. However, in real conditions, it depends on the flying style:

• Indoors, with a calm style – up to 5 minutes.
• In acro mode – 3-4 minutes.
• In open space, where there's wind influence – approximately 3 minutes.

Flight characteristics slightly lag behind lighter TinyWhoops with analog video, as the weight here is twice as much.

Is It Worth Its Cost?

If you're looking for a TinyWhoop on 1S batteries with a DJI digital video system, then Meteor75 Pro O4 is a good choice. However, if you need a more powerful option, consider 2S drones.

As a training drone, it's not quite suitable. The cost of $200 can be a barrier for beginners who haven't yet decided if they'll engage in FPV as a full-fledged hobby. Also, consider that drone repair can be expensive due to the digital system. Therefore, if you're just starting out, it's better to look at analog models. However, if your budget allows and you're not afraid of possible breakdowns, this drone will provide excellent video quality.
