It’s good to see BetaFPV releasing another new tiny whoop in its Meteor series, and this time we’re looking at the Meteor75 Pro II Analog. I previously tested the DJI O4 Wide version of the Meteor75 Pro II, and it was much more powerful than I expected. The analog version is lighter, which makes it even more interesting from a performance perspective.

What’s New?
Compared with the original Meteor75 Pro, almost everything has been updated: the flight controller, motors, propellers, frame and camera.
The main thing BetaFPV has kept is the canopy design.
It is essentially the same quad as the O4 version I reviewed earlier this year, just with a different FPV system and canopy, so it is noticeably lighter. You can see my review of the O4 version here: https://oscarliang.com/betafpv-meteor75-pro-dji-o4-wide/
One thing I would like BetaFPV to improve is the antenna mounting.
At the moment, the antenna is left flopping around freely. The wire may occasionally move and hit the canopy during flight and introduce unwanted vibration. I also worry it could get caught on something or detach during a crash. A more secure mounting solution would be welcome. Maybe you could just add a dab of E6000 glue yourself to hold it in place.

Flight Controller
The Matrix 5in1 FC integrates most of the electronics needed for the quad onto a single PCB:
- Flight controller
- 12A 4in1 ESC
- 2.4GHz ExpressLRS receiver
- 400W 5.8GHz Analog VTX
- Betaflight OSD
The motors also use plug connectors, so installing or removing motors is easy.
One interesting detail is that BetaFPV currently produces this board with several different gyro options (ICM42688P / ICM42622 / BMI270 / LSM6DSK320X), likely due to inconsistent gyro availability. You won’t know which gyro you might get until you receive it.
BetaFPV appears to provide firmware and tuning specifically matched to each gyro variation.
Mine is BMI270.
Motors, Propellers, Power and Efficiency
The Meteor75 Pro II uses BetaFPV’s newer 1102 motors together with 45mm Gemfan propellers (1.8-inch).
Compared with the previous generation, this motor and prop combination feels noticeably more powerful, but it is also much more power hungry.
At high throttle, the quad delivers a surprising amount of power and can go very fast. However, you need a battery with very high C rating to get the most out of it. Even with BetaFPV’s latest Lava II batteries, I was still frequently getting low-voltage warnings during hard punch-outs.
On the other hand, if you fly gently, the quad can be very efficient.
If flight time is your priority, keep the throttle low and cruise around. You could also reduce the motor output limit or throttle scale to tame the power and improve endurance: https://oscarliang.com/throttle-scale/
16:9 Camera?
BetaFPV’s specifications state that the camera has switched from 4:3 to 16:9.
If that were the case, I would expect the image to look noticeably distorted when viewed on goggles locked to 4:3.
However, that did not happen in my testing. The image looked fairly normal in 4:3 mode.
So I am not completely sure whether the listed 16:9 specification is correct, or whether there is something else going on with the camera output.
For now, I would treat that specification with some caution.
Also the camera tilt angle is not adjustable which is a slight inconvenience. As it is, it flies fine outdoor, but I wish the camera angle was adjustable which makes it more flexible.
Flight Performance
Because the analog version is lighter than the DJI O4 version while using basically the same power system, the flight characteristics are quite different:
- The O4 model feels slightly heavier and more planted.
- The analog version is lighter, more punchy and more responsive.
Estimated top speed was around 85km/h, slightly faster than the o4 version.
The first thing I noticed was how much more punchy it feels. The hover point is very low, and the quad feels extremely light in the air. That is great for outdoor flying.
I tested it in around 15mph wind, and while it was constantly being pushed around, it was still flyable. Going through small gaps became more challenging, but I was surprised by how stable it remained in those harsh conditions.
Freestyle is also a lot of fun. For a 1S Whoop, it feels impressively powerful and responsive. The downside is that aggressive flying requires very good batteries.
Even halfway through a battery, a full throttle punch could pull the voltage down to around 3.1-3.2V, sometimes even lower. Because of that, I strongly recommend displaying mAh drawn in the OSD rather than relying entirely on voltage to judge remaining capacity. You need to calibrate it first though – I will provide my current sensor scale later under “how to setup” in this review.
Custom PID Tune
The stock PID tune works fine, but I found it fairly conservative.
I re-tuned mine by slightly reducing filtering and pushing the PID gains much harder.
The result was a more responsive and snappier quad that I found more fun to fly.
However, my more aggressive tune works best in calmer weather.
If you regularly fly in windy conditions, the stock tune may actually feel smoother because its slower response reacts less aggressively to wind disturbances.
As usual, I share my custom PID tunes on Patreon: https://www.patreon.com/oscarliang/posts/pid-tune-for-pro-171828544…
Battery Options
I tested the Meteor75 Pro II with these BetaFPV Lava II batteries, they all fit the battery tray perfectly:
- Lava II 1S 480mAh
- Lava II 1S 580mAh
- Lava II 1S 680mAh
Battery choice has a noticeable effect on both flight time and handling. Personally, I prefer the 580mAh pack because it gives a good balance between agility and endurance.
My approximate flight times were:
- 480mAh: around 4 mins
- 580mAh: around 5 mins
- 680mAh: around 6 mins
Flight time is heavily influenced by how aggressively you fly, I normally fly quite aggressively, so my flight time might be on the low side.
I am nowhere near BetaFPV’s claimed flight times during my testing, but that is probably due to my flight style and testing conditions. If you cruise gently and avoid hard throttle punches, you should be able to get considerably longer flights.
How To Setup
Firmware:
- FC: The flight controller comes preloaded with Betaflight 2025.12.5 firmware. FC Board Target: BETAFPVG473_V2. Stock CLI diff can be found here.
- ESC: Bluejay, 0.19, 96kHz (A-X-5)
- RX: BETAFPV 2.4GHz AIO RX, Firmware Rev. 3.5.6.
Bind ELRS radio: In Receiver tab, press the Bind Receiver button at the bottom right of your screen. In your radio, go to the ExpressLRS Lua script, and put your transmitter in bind mode. For detail steps see this guide: https://oscarliang.com/bind-expresslrs-receivers/#Method-1-Bind-Button-in-Betaflight-Configurator
Here are the main settings I recommend checking:
- In Power & Battery, set minimum voltage to 3.2V, set warning voltage to 3.4V.
- In Receivers tab, enable Telemetry Output
- In Presets tab, load ExpressLRS preset according to the packet rate you are using
- In PID Tuning tab, go to Rateprofile and enter your own rates. It’s fine to leave it at default, or you can try my rates: https://oscarliang.com/rates/#My-Rates.
- In Modes tab, setup your switches for Arming, Angle mode, Beeper etc.
- In OSD tab, setup your OSD elements, you can copy mine CLI here: https://oscarliang.com/betaflight-osd/#Analog-without-GPS
Final Thoughts
The BetaFPV Meteor75 Pro II Analog is a surprisingly powerful upgrade. It is probably one of the most powerful 1S 75mm Whoops I have flown so far.

The biggest thing to watch out for is how power hungry it can get when you push it hard. If you want to fly aggressive freestyle, you will definitely want fresh, high performance batteries.
But that is only one side of its personality.
If you fly gently and use it for casual cruising, it can also be quite efficient and deliver respectable flight times.
That combination is what makes the Meteor75 Pro II interesting: it can be a relaxed cruiser when you want it to be, but there is a surprising amount of performance available when you open the throttle.
