GAPPED FPV — FPV drone simulator

GAPPEDFPV FPV drone simulator

An FPV drone simulator made by a pilot, for pilots. Physics calibrated against a real whoop’s blackbox, Betaflight-style rates and PID, and real homes to fly through.

Why this sim

Made by a pilot, for pilots

Nine real whoops and micro drones, each with its own weight, motors, props and battery, on a flight core of its own calibrated against the blackbox of a real flight. More than 20 maps built around gaps to fly through. And on every circuit, three ways to fly, your own ghost and medals to win.

  1. Real physics

    Its own flight core at 2,000 Hz · calibrated with a real blackbox

    • Deterministic C++ core: the same inputs give the same flight on any PC.
    • Calibrated against a real whoop’s blackbox and five real laps of its circuit.
    • ACTUAL or Betaflight rates, and the PID with the configurator’s numbers.
    • LiPo and LiHV batteries that sag and warm up; gravity, thrust and drag you can bend.
    Real physics
  2. Go for the medal

    Free flight · time attack · race · ghosts · championship

    • Medals on every circuit, daily and weekly challenges and a championship of three cups.
    • Race your best lap as a ghost, with the split at every gate and a lap trainer.
    • Exact replays: FPV, chase or free camera, from 0.25× to 4×, and MP4 export.
    • A flight school with eight lessons: arming, hovering, turns, flips and landing.

  3. Your hangar

    Real whoops, batteries and radio · build yours piece by piece

    • Nine micro drones and whoops modelled part by part, in their real colours.
    • Pick the battery: its capacity and weight change how it flies.
    • Build your own on a real frame: motors, props, board, camera and canopy.
    • Change the motor KV, the camera angle and FOV, save your versions and win new paint jobs.

  4. Your home is the circuit

    Circuit editor · more than 20 maps · day and night with baked light

    • A first-person editor: place arches, LED hoops, posts and objects; the racing line draws itself.
    • More than 20 maps: two real flats and their estate, a cathedral, a market, a bowling alley, a canyon, a cove…
    • The homes by day and by night, with the light baked in Blender Cycles.
    • Fly your own house: a phone scan becomes a level.

In-game

From your living room to a Gothic cathedral

Every map is built for whoops, full of real gaps to fly through. Screenshots straight from the game, in 4K.

The cathedral under construction

03

A Gothic cathedral under restoration: the 28 m high nave with its stained glass, the crossing scaffold up to the vault, the triforium, the choir with its organ, the altarpiece, the bell tower up the spiral staircase and the cloister.

Food market

04

A covered iron-and-glass market full of life: aisles between 36 stalls of fruit, bread, cheese and flowers, the central bar, the glass lantern and the square with its fountain and terrace.

The bowling alley

02

An eighties bowling alley with arcade machines and a skating rink: fly over the pins and inside the machine, between the arcades, through the blacklight maze and under the mirror ball. For tiny whoop.

Casa David

04

A real flat modelled from photos and floor plans, with its own furniture and 2.5 m ceilings: tight lines for a micro drone, by day and by night with the light baked in Blender Cycles.

Casa Rico

04

Another real flat — living room, kitchen, three bedrooms and a terrace — modelled from photos and floor plans, by day and by night with the light baked in Blender Cycles.

Pine Park

04

A park for tricks: tower and tube slide, skatepark, pond with a bridge, fountain, gazebo, pergola, track and a grove of pines.

Rico housing estate

04

A real housing estate: a 6th-floor flat inside, the courtyard with the pools, the gardens and the playground, and the basement garage. Outdoors, by day.

Western canyon

02

A desert canyon with a movie Wild West town: rock arch, pinnacles, trestle bridge, mine tunnel, bell tower and porches. Outdoors, by day.

Lighthouse cove

01

A Mediterranean cove for freestyle: cliffs, an arch over the water, caves and a sinkhole, the pier, the stairs and the lighthouse with its gallery. Outdoors, by day.

Roadmap

From whoops to 5"

Whoops and micro drones are where it starts, not where it ends. Next: cinewhoops and 5" quads, with maps built to their size.

  1. Flying now

    Whoops and micro drones

    Nine real quads; free flight, time attack and race with medals, ghosts, exact replays, a championship and daily challenges; a circuit editor; nine languages.

  2. In progress

    More than 20 maps

    New maps indoors and out, from real homes to invented places, until there are more than twenty.

  3. In progress

    Steam page & wishlist

    Store page, trailer and the first public builds for testers.

  4. Next

    Bigger quads, bigger maps

    From 3" cinewhoops to 5" freestyle, with bigger maps built for them.

  5. Next

    Online leaderboards

    Replay-verified lap times: the run is re-simulated, so a record cannot be faked.

FAQ

Questions

When does it come out, and how much will it cost?

It is coming to Steam on Windows. The date and price are not set yet — join the list and you will be the first to know (and to get a test build).

Which drones can I fly?

Today, nine micro drones and whoops, each with its own weight, motors, props and battery, and you can build your own from their parts. Bigger quads (3" to 5") are on the roadmap.

What do I need to play?

A Windows PC and, ideally, your own radio connected by USB or Bluetooth: a wizard calibrates it step by step. A gamepad works too, and you can even try it with the keyboard.

Is the physics really realistic?

It was calibrated piece by piece against the blackbox log of a real whoop and five real laps of the same circuit, and what was measured went into every whoop. It is also deterministic: the same inputs give exactly the same flight on any PC.

Which languages?

Nine: English, Spanish, French, Italian, German, Brazilian Portuguese, Polish, Russian and Simplified Chinese. The voice that calls out your laps speaks Spanish.
