Real acro physics, four maps, and two on-screen sticks that actually work on a phone. Plug in a transmitter over USB if you have one. Nothing to download, no account to make, and once it's installed it flies without internet.
Two race tracks with gates and a lap timer, two tight spaces for freestyle. All free, all in the browser, all playable on a phone.
A calisthenics park behind a mesh fence: pull-up bars at four heights, monkey bars, wall ladders, rigs, a climbing wall and a quarter pipe. No gates and no timer here. You pick the line, and every bar is solid.
An open course in the spirit of Liftoff: ten gates, checkpoints, split times and a minimap. This is where you learn to carry speed through a turn instead of braking into every gate.
A factory floor 110 by 80 meters, with structural columns, an overhead crane, a conveyor and a mezzanine you can fly under. Three tracks, from a clean lap of the floor to a vertical route that climbs under the crane.
A low ceiling, concrete pillars, parked cars and not much room between any of them. Nothing here rewards speed. It is the map for learning throttle control and for threading gaps you would not risk on a real quad.
Two on-screen sticks in a Mode 2 layout, sized for thumbs, with the throttle behaving the way a real transmitter does.
Throttle up and down, yaw left and right. It sits in a fixed place, because throttle is a position, not a nudge.
Pitch and roll. It appears wherever your thumb lands, so you are never reaching for a circle drawn in the wrong spot.
Lift your thumb and the throttle stays put, exactly like a real radio. One tap switches it to spring back to a hover if you would rather learn that way.
Nothing is dumbed down for touch. It is the same acro model, the same crashes, the same lap times as on a desktop.
Switch the builder on inside any map, fly the line you want and leave gates where you like. The track is encoded into a link: send it and your friend flies it with the same lap timer. No account, nothing stored on a server.
Fly and press GATE where you want one. No lists, no coordinates, no meters.
While you build, the quad hovers and cannot crash: up, down, forward, back, sideways, turn. Placing a gate works the first time.
The builder copies whatever track is open. Fly up to a gate, remove it, drop a new one: the rest of the course stays exactly as it was.
Everything lives in the page address. The link opens on a phone or a laptop, and works offline in the installed app.
The site installs like an app: its own icon, full screen, no address bar. After that all four maps run offline.
Nothing to find in an app store. Two or three taps on this page and it is on your home screen.
Subway, cabin, dead roaming, a field with no signal. The maps are already on the phone.
All four maps plus the 3D engine. Less than a single photo from your camera.
No ads, no account, no in-app purchases, no telemetry that follows you anywhere else.
Every FPV pilot will tell you the same thing: the first hundred hours belong in a simulator. It is cheaper, it is faster, and nothing snaps.
An FPV simulator reproduces how a quadcopter flies from the pilot's point of view. What you see is what a video receiver would feed your goggles: a HUD with battery, speed, altitude and an artificial horizon.
fpv0 flies in acro, the rate mode every racer and freestyle pilot uses. No self-leveling, no training wheels. The quad does exactly what your sticks tell it to, including nothing at all when you let go.
Liftoff, VelociDrone, Uncrashed and DRL are excellent, and they are also multi-gigabyte installs, a store account and a graphics card. fpv0 opens in two seconds in a tab you already have.
It is not a replacement for a full sim when you are training for a race. It is the thing you use before you own a quad, between packs, in a hotel room, or when a friend says "let me try" and you do not want to install anything.
People who have not bought a quad yet. FPV sticks feel wrong for the first few hours and every mistake on real hardware costs props. Do the crashing here.
Pilots who already fly. A warm-up before a session, or a specific move drilled over and over: power loop, split-S, a gap you keep missing.
Anyone curious. Find out whether flying acro is your kind of thing before spending anything.
WebGL physics running at 60 fps, four maps, three track layouts on the racing ones, lap timing with splits, a minimap and a gate pointer.
USB transmitters and gamepads through the Gamepad API with full axis calibration, on-screen sticks on phones, adjustable rates, and a HUD that looks like the one in your goggles. Free, no ads.
No progression system, no unlocks, no currency. Open a map and fly.
Every gate is timed. Beat your own lap and the split tells you where you found the time, or lost it.
Any USB gamepad or FPV radio in Joystick mode: RadioMaster, Jumper, TBS, FlySky, FrSky, Xbox and PlayStation pads.
A four-step wizard works out which stick is throttle, yaw, pitch and roll on your radio. You do it once.
Rate mode across all three axes, with prop wash, motor spool and battery sag. Angle mode is there while you learn.
Your position, the gates and the direction of the next one, live, so you know where the track went after a crash.
Vignette, scan lines and chromatic aberration. It looks like a picture coming off a real analog link.
A real transmitter over USB is best. A phone and a keyboard both work, and neither is a toy version.
WebGL, which means almost anything made in the last eight years.
If yours is not here, the answer is almost certainly "yes, it is free and no, you don't need an account".
Completely. No subscription, no donations, no in-game purchases, no ads. Nothing is gated behind an account because there are no accounts. Open it and fly.
No. It is WebGL and runs in the browser. Chrome, Edge, Firefox and Safari all work.
If you want, you can install it as an app on a phone. That gives you an icon on the home screen and makes the maps work offline. It is still not an app store download: the site installs itself, using the browser.
Yes, and this is the part most browser simulators skip. You get two on-screen sticks in a Mode 2 layout, with the throttle holding its position the way a real radio does, or springing back to a hover if you prefer.
A PC with a transmitter is still better for serious practice, but a phone is a perfectly reasonable way to get some stick time in.
Yes. Most modern radios support USB Joystick or Sim mode: RadioMaster TX16S, Jumper T-Pro, TBS Tango 2, FlySky, FrSky. Plug it in over USB, switch it into that mode, and the browser sees it as a gamepad.
Then run the calibration in the menu. It walks you through four sticks and maps the axes itself, so you don't have to guess which one your radio calls axis 3.
Acro is the default and the point. That is rate mode, the one every racer and freestyle pilot flies: the quad does not return to level on its own, you command angular rate on all three axes.
Angle mode is there too, one key away, for the first hour.
Stick calibration and your throttle preference are stored locally in the browser and never leave your device. Clearing site data resets them.
Your best lap lives until you reload the page. There are no cloud profiles or leaderboards yet.
No. fpv0 is a sports simulator: gate racing, freestyle, timed laps. Weapon models, payload release, a targeting reticle and "hit the target" game modes will not be in it. That is a decision for as long as the project exists, not a list for today.
What we do not build, and why, is in the terms of use.
No account, no name, no email. What is collected is anonymous: which map was opened, phone or desktop, which control method, how long the session ran. That is how we decide which map to build next.
None of it identifies a person, there are no ads and no third-party trackers. If your browser sends Do Not Track or Global Privacy Control, nothing is sent at all. Details are in the privacy policy.
Those are full paid simulators with deep physics, drone customization and online leagues. They are also large downloads and a purchase.
fpv0 is the free, light one that opens in a tab: for first steps, for a warm-up, and for handing your phone to someone who wants to see what FPV feels like. Different tools. Owning one does not stop you wanting the other.
