The BetaFPV P1 and FPV Lap Timer: cheap HD, real lap times
The BetaFPV P1 makes HD FPV cheap enough to try on a whim. It also comes with one big question: does the extra latency make you slower? Forum arguments won't settle that, but a lap timer will, and the one in your pocket needs no setup on the P1 side at all.

FPV Lap Timer is an independent app and isn't affiliated with BETAFPV. Check betafpv.com for current P1 products, firmware and manuals.
What is the BetaFPV P1?
The P1 is BETAFPV's budget digital FPV system, built on its ArtLynk protocol. A tiny camera and video transmitter on the quad sends 1080p 60fps video to a compatible receiver. The appeal is price and weight. Oscar Liang weighed the whoop version at 7.1g with its camera and PCB antenna, and Joshua Bardwell put it at about $40, in line with analog gear.
The catch is latency. Both reviewers measured roughly 65ms, against about 20ms for analog, and neither recommends the P1 for serious racing. Bardwell also found that a weak signal goes blocky instead of stuttering, and that the video holds up well behind obstacles. For whoop practice and learning a track, that can be a very fair trade.
How the P1 system works
- On the quad: the P1 Air Unit combines the camera and VTx, with output adjustable from 25mW to 200mW. It has no onboard recording.
- On your face or tripod: VR04 HD goggles are the simplest receiver. The Nano VRX fits the module bay of Skyzone or Fat Shark goggles, the external VRX outputs over HDMI, and the P1 monitor has a built-in screen.
- For recording: your receiver saves the footage to a microSD card. Betaflight OSD isn't burned into the video, which matters later if you want to see your lap data on your clips.
Getting started with the P1
- Choose your quad. A ready-made P1 whoop like the Meteor75 Pro, or an RTF kit like the Aquila20 HD, is the easy route. Adding an Air Unit to your own build? It takes 5V and uses a 6-pin DJI Air Unit-style cable, so confirm your flight controller's output first.
- Choose your receiver. VR04 HD goggles cost about $200. Stick to BETAFPV gear to start, as Bardwell found that mixing ArtLynk brands wasn't reliable.
- Update and bind. Bring both ends onto matching firmware, then bind and select the same channel. Steps vary by product, so follow your manual, such as the P1 Air Unit guide.
- Add a microSD card so you can review your DVR footage after each pack.
Why the P1 and FPV Lap Timer work so well together
FPV Lap Timernever touches your video link. It uses your phone's camera to watch for your quad crossing a gate. To the app, a P1 whoop is simply a small object moving across a line, so compatibility isn't something you have to work out. Here's what that means on a P1 quad:
- No RF setup. RSSI timers read a VTx's signal strength and need calibrating for your space. A camera timer has no frequencies or thresholds tied to your VTx, and changing P1 channels changes nothing.
- Zero grams added. You chose a 7g video system to keep your whoop light. There's no transponder to mount and no wiring to do, because all the timing hardware is your phone.
- Free to start. You've just bought into a budget system, so it would be odd to spend more on timing. Lap timing is free on iPhone and Android.
- Your eyes stay in the goggles. Laps and splits are called out loud, so you never need to lift your goggles to check a time.
- Your DVR gets its missing lap data. P1 footage has no burned-in OSD, so a clip on its own won't tell you how fast the lap was. Clip Studio puts your DVR and your timer screen recording side by side, right in your browser.
Find out what the latency really costs you
Here's the fun part. If you own an analog whoop too, fly both on the same track on the same day: warm up, then fly a few packs on each and compare your best lap and consistency. A spec sheet can tell you the P1 has more latency. Your lap times will tell you whether it matters at your level, on your track.
Timing a small whoop indoors takes a little care with phone placement. Fix the phone on a tripod, frame the gate side-on and keep the background calm. Our Tiny Whoop lap timing guide has the full setup. If your P1 whoop is headed for a home track, the RaceGOW lap timer guide is your next stop.
Frequently asked questions
Does FPV Lap Timer work with the BetaFPV P1?
Yes. FPV Lap Timer uses your phone's camera to watch the quad cross a gate. It never reads your video signal, so it works the same on a P1 quad as on analog, HDZero, Walksnail or DJI.
Do I need to set a channel or connect the app to my P1 goggles?
No. The app has no connection to your VTx, goggles or flight controller. Mount the phone, line the gate up with the red centerline and hit Start. Your P1 channel makes no difference.
Is the BetaFPV P1 good for racing?
It isn't the first choice for competitive racing. Reviewers measure about 65ms of latency, compared with about 20ms for analog. It's still a capable system for whoop practice at a low price, and timing your laps is the best way to see how much the latency affects your own flying.
What do I need to start with the BetaFPV P1?
You need a P1 transmitter and a compatible receiver. The simplest route is a P1 whoop such as the Meteor75 Pro with VR04 HD goggles. If you build your own quad, add a P1 Air Unit. If you already own Skyzone or Fat Shark goggles, the P1 Nano VRX is an alternative to buying new goggles.
Can I combine my P1 DVR with my lap times?
Yes. Save a screen recording from FPV Lap Timer, then load it into Clip Studio with your P1 DVR footage. It syncs the two videos into one side-by-side clip in your browser, and nothing is uploaded.
