ArtLynk is a brand new HD digital FPV system. It’s low cost, the picture high quality seems promising, and for some individuals it may turn out to be a possible different to DJI and Walksnail Avatar. The BetaFPV Meteor75 Professional is the second BNF quad geared up with the ArtLynk P1 Air Unit, and on this evaluate I’ll take a look at the way it flies. I’ll additionally have a look at the newest ArtLynk V2.0.6 firmware and whether or not it brings any noticeable enhancements.

Design
Nothing has actually modified with this new Meteor75 Professional Tiny Whoop. It’s principally similar to the Meteor75 Professional O4 version I reviewed over a yr in the past. The one actual distinction is that this model comes with the ArtLynk P1 Air Unit as an alternative of the DJI O4.
The ArtLynk FPV system is principally a funds HD digital FPV system. It prices about the identical as analog, however gives considerably higher picture high quality. The principle draw back proper now could be the marginally larger latency. I already reviewed the ArtLynk system, so test that out if you happen to haven’t already: https://oscarliang.com/betafpv-artlynk/
The Meteor75 Professional P1 got here with an outdated model of the Artlynk firmware (V1), and I up to date it to V2 when testing it. I documented the method of flashing firmware right here: https://oscarliang.com/update-betafpv-artlynk-firmware/
If you wish to be taught extra concerning the parts, such because the FC and motors, take a look at my authentic evaluate of the Meteor75 Professional right here:

Flight Efficiency, Vary, and Latency
Really useful batteries: LAVA II 1S 580mAh / 680mAh LiHV battery. I examined these batteries prior to now and so they had been a number of the greatest in the marketplace: https://oscarliang.com/betafpv-lava-ii-1s-battery/#580mAh
I examined each on the Meteor75 Professional:
- 580mAh: 4–5 minutes flight time
- 680mAh: 5–6 minutes flight time
The quad hovers at round 33% throttle.
The best way it handles, feels precisely just like the older Meteor75 Professional with the O4. Right here’s a video exhibiting its efficiency.
Because the second BNF quad geared up with the P1 Air Unit, the Meteor75 flies so significantly better than the Aquila20, regardless that it is just a 1S quad. The decrease weight makes an enormous distinction in flight characterstics. It feels far more nimble, responsive, and quieter. I believe BetaFPV ought to have used the Meteor75 of their bundle as an alternative.
Vary is nice at 500m+. The bitrate solely drops from 21Mbps to 16Mbps, so it may well most likely go lots farther. Nevertheless, bitrate is usually a bit delicate at occasions, and jumps round greater than DJI and Walksnail, and when bitrate will get too low you get drop frames and stuttering video. It simply doesn’t really feel as stable or dependable as DJI, so I’d probably not use it for long-range flying proper now. Additionally the VTX is simply 200mW max output energy in spite of everything.
In my testing, latency has not modified a lot with the newest V2.0.6 firmware. It’s nonetheless round 50–60ms, principally the identical because it has been since launch. It’s fairly excessive for an FPV system. It may really feel a bit bizarre when doing time-critical maneuvers, particularly noticeable if you happen to fly ArtLynk and different mainstream programs again to again (e.g. DJI). With that stated, it’s completely flyable for cruising and primary freestyle, however I’d not belief it for bando flying or racing.
The way to Setup
The FC goal is BETAFPVG473, and it got here loaded with Betaflight 4.5.3. The unique CLI diff may be discovered right here.
The onboard ELRS receiver firmware goal is BETAFPV 2.4GHZ AIO RX, Firmware model is 3.5.6.
ESC: A-X-5 – Bluejay, 0.19, 96kHz
- Bind ELRS Receiver: For some motive, the ELRS receiver received’t go into WiFi mode after ready a few minutes, so I needed to bind the receiver utilizing one other methodology. I merely clicked the “bind receiver” choice within the receiver tab in Betaflight. Then, on my radio, I went into the ExpressLRS Lua script and chosen the Bind choice. And binding was finished.
- Pair P1 Air Unit to the VR04 HD Goggles:
- Merely energy them on, and press the bind buttons on each gadgets
- If they aren’t binding, chances are high they’re on completely different firmware model (V1 received’t work with V2), it is advisable to both downgrade or improve the firmware in order that they match: https://oscarliang.com/update-betafpv-artlynk-firmware/
- Presets tab in Betaflight Configurator:
- make a backup of your settings utilizing the Backup button
- load ExpressLRS preset primarily based in your packet charges, : https://oscarliang.com/rc-link-preset-betaflight/
- Modes tab: Configure the switches for arming, angle mode, and turtle mode.
- Energy tab: Set the minimal cell voltage to three.2V and the warning to three.4V (land earlier than 3.2V).
- Receiver tab: Allow Telemetry.
- PID Tuning tab: In Charges, disable Throttle expo by setting it to 0; If you wish to set Throttle Expo correctly, it is best to tune it following this information: https://oscarliang.com/throttle-mid-expo/
- OSD tab: choose HD Video Format, and cargo my CLI settings: https://oscarliang.com/betaflight-osd/#HD-without-GPS.
Enhancements You Can Make
Strive HQ triblade props (1.8×1.2×3). They’re smoother than the inventory props and should assist scale back jello.
Use Throttle Mid/Expo if you happen to battle with flying indoor: https://oscarliang.com/throttle-mid-expo/
In case you are a hardcore, skilled pilot, you possibly can take into account direct-soldering the motors to the FC as an alternative of utilizing motor connectors. I’d not suggest this for learners, as a result of the solder pads are tiny and it’s not a simple modification. But it surely does provide just a few advantages:
- Much less resistance, higher efficiency (extra energy and extra environment friendly)
- Prevents failure resulting from dangerous metallic contact
PID/Filter Tune – The quad comes with a customized tune, however I’m not certain it’s optimized. Personally, I really feel I’d have tuned it in a different way utilizing Blackbox. I’ll attempt to retune it and share my settings on my Patreon.
Conclusion
In case you are closely invested within the Artlynk FPV system, The BetaFPV Meteor75 Professional P1 is a good tiny whoop to contemplate. It’s not the perfect flying whoop on the market as a result of it’s nonetheless fairly heavy, however there’s merely not that many decisions in the marketplace in the mean time. Even so, in comparison with the Aquila20, this quad makes a significantly better showcase for what the ArtLynk system is definitely able to.
The principle limitation remains to be the latency. Whereas the newest V2.0.6 firmware doesn’t appear to enhance it, the system remains to be flyable for cruising and informal freestyle. It simply doesn’t really feel as related or confidence-inspiring as DJI or Walksnail when you find yourself pushing tougher or flying in additional demanding environments.
In case you are interested by ArtLynk and wish an reasonably priced method to get into this new digital FPV ecosystem, the Meteor75 Professional P1 is at present probably the greatest choices obtainable. It’s comparatively protected and enjoyable to fly. Not good, however undoubtedly promising.
