Open-source FPV simulator · MIT
ShramkoGSFPV turns SuperSplat Gaussian Splatting scans into places you can fly: Betaflight-style rates and PID, walls you actually crash into, and your own radio over USB or touch sticks. Nothing to install.
Works best in desktop Chrome or Edge with WebGPU.
01How it works
No account, no download. The scene streams straight from SuperSplat into your browser.
01
Start with one of Andrii's scans or paste the link to any public SuperSplat scene.
02
Plug in an EdgeTX radio in USB joystick mode (WebHID), use a gamepad, or fly with touch sticks.
03
Move the sticks once to calibrate, arm with the throttle all the way down — like a real quad — and go.
02Why it feels real
An own flight model — four motors, a mixer and a rate PID — flying inside the real geometry of the scan.
Every physics tick sweeps the drone's body against the scan's voxel collision data, so a fast quad can't slip through a thin wall between frames.
Hit something hard and the quad tumbles and throws debris. Brush a wall gently and it slides along it.
Betaflight, Actual, KISS and Raceflight rate curves match compiled Betaflight 4.5.1 to the last digit.
Flights are recorded as stick input and replay deterministically: the same inputs always give the same flight.
Earth, Moon, Mars or zero-g. On the Moon the same drone gets extremely twitchy — the “keep thrust-to-weight” switch tames it.
Default craft
Every number says where it comes from.
“Class” means the numbers follow public specs and measurements. BetaFPV does not endorse this preset.
03Live numbers
Each figure is read from the repository's evidence file when this site is built. If a measurement goes missing, the build fails.
1880 points, max error 0 deg/s
0 wall pass-throughs in 200,000 straight passes
Pavo20 Pro body stops 47.2 mm (median) beyond its own size from walls on the 5 cm voxel collision of scene 39e63ce9
The test display runs at 30 Hz, so this result is bounded by the screen rather than by the simulator. It is published, but it is not gated.
Stick-to-photon latency with a camera has not been measured yet.

05Works with your radio
An honest matrix: nothing is marked as tested unless it was, and so far that means emulation or a simulated radio.
Browser: Chrome / Edge, desktop
Input: EdgeTX radio (RadioMaster TX16S, Boxer, Pocket, Zorro) as a USB joystick over WebHID
Status: Not tested on real hardware yet — tested with a simulated EdgeTX radio
Browser: Chrome / Edge, desktop
Input: Gamepad
Status: Not tested on real hardware yet
Browser: Chrome / Edge, desktop
Input: DJI remote as a gamepad
Status: Not tested
Browser: Safari, iPad, Android
Input: Touch sticks
Status: Tested in emulation
Browser: Firefox
Input: Radio or gamepad
Status: Scene viewing only — radios need Chrome or Edge (no WebHID)
Have an EdgeTX radio? A short test report helps a lot — use the contact form below or open an issue on GitHub.
06Why this is better
Facts as of September 2026. “Unknown” means we could not verify it.
| Feature | ShramkoGSFPV | Walking in the SuperSplat viewer | Browser splat-FPV demos (e.g. SplatFPV) | Classic FPV simulators (fixed maps) |
|---|---|---|---|---|
| Real scanned places | Any public SuperSplat scene | Yes | Yes, one file at a time | No, fixed maps |
| Drone model | 4 motors, mixer, rate PID | None: a walking or flying camera | First-order rate filter | Full |
| Your own rates | Betaflight, Actual, KISS, Raceflight | Not applicable | Flat max rate plus expo | Yes |
| Hitting a wall | Crash and tumble | Slide along it | Stop or slide | Crash |
| Collision source | SuperSplat's voxel octree, swept test | SuperSplat's voxel octree | Rebuilt at load, point test | Hand-made meshes |
| Radio input | EdgeTX over WebHID, gamepad, touch | Gamepad | Gamepad API | USB joystick |
| Published test numbers | Yes, see Live numbers | unknown | unknown | unknown |

Classic simulators are still the place to train for races on purpose-built tracks. This project is about flying real places.
07For your AI agent
Paste this into Claude Code, Codex, Cursor or any coding agent. It installs the project, runs the checks and opens the simulator locally, and only asks you for passwords or physical actions.
Set up ShramkoGSFPV for me by following https://github.com/AndriiShramko/ShramkoGSFPV/blob/main/AGENT_SETUP.md exactly. Install, run the checks, start the simulator locally and open it in Chrome. Do not change any system settings; ask me only if a step needs my password or a physical action.rules for coding agents working in the repo

08Risks & safety
Short and honest, so nothing catches you by surprise.
Scenes load from SuperSplat's public but undocumented CDN. It can change at any time, and some scenes may stop loading.
Those scenes can be flown through, not crashed into. In-browser collision baking is coming.
Crashes and fast flight can make you queasy, so take breaks. Effects never flash the whole screen, and your reduced-motion setting is respected.
Practise responsibly, follow your local drone law and never fly over people.
Calibration, flight history and favourites are stored only in your browser.
09FAQ
Open ShramkoGSFPV in desktop Chrome or Edge, pick one of Andrii's scans or paste a SuperSplat link, connect a radio, a gamepad or touch sticks, then calibrate, arm and fly. There is nothing to install.
That is what it is built for: switch an EdgeTX radio such as the TX16S, Boxer, Pocket or Zorro to USB joystick mode and connect it over WebHID in Chrome or Edge. So far this has been tested only with a simulated EdgeTX radio, not with real hardware.
Yes. ShramkoGSFPV is free and open source under the MIT license. It runs on WebGPU in desktop Chrome or Edge, with no download.
Any public SuperSplat scene, by link or id. Scenes that come with voxel collision data have solid walls; the rest can be flown through but not crashed into until in-browser collision baking lands.
Touch sticks have been tested in emulation only, not on real devices yet, and you need a browser with WebGPU. Radios need desktop Chrome or Edge.
The rate curves (Betaflight, Actual, KISS, Raceflight) match compiled Betaflight 4.5.1 to the last digit, and a rate PID drives four motors through a mixer. It is our own flight model, not Betaflight firmware.
On scenes with collision data you crash: the drone's body is swept against the voxel data on every physics tick, and a test harness checks that fast flight cannot tunnel through walls. See Live numbers for the result.
Yes, MIT. Code, measurements and design decisions are on GitHub. Betaflight's formulas were re-implemented; no GPL code was copied.
