29 September

New

• Stick help. A stick that does nothing in flight is caught, and a banner says so. The Stick help screen shows where the signal is lost, in the radio, the browser or the system, and it checks with your hand on the stick before it tells you what to do. It is a row on the pause menu and in Settings, and a bug report carries what it found.
• Settings, Screen, Manga and scoring turns off the manga look and the score readouts with one switch: the speed lines, the impact frame, the lettered callouts, the score, the Tail meter and the lettered menu titles. Nothing that counts changes. The scorer, the chase, a scored run's clock and your bests run as they did.

Sticks

• A radio that Firefox calls a game controller flies the right channels. On Firefox for Linux the throttle was reading as yaw, and pitch as a switch channel.
• Chrome on Android hands a radio four axes and drops the rest, so yaw or throttle goes missing. Stick help says so where you are stuck.

Fixes

• A track with an absurd yaw, like 1e20, froze the tab in the builder. Big angles are brought back to the circle first.
• A settings entry saved as null stopped the sim from starting. It reads as no settings now.
• Every map swap left the town's instanced buffers behind. They are freed.
• The tune's CLI download let go of its file the moment it was clicked. Safari and older Firefox start a download after the click returns, so it waits four seconds now. That fix comes from the code and has not been run in those browsers.

28 September

New

• Settings has a HUD section. Its first row is Crosshairs: Off, Wings, Cross or Dot. It starts Off.

Feel

• The default tune has a quarter more feedforward. Stick response is 125, with F at 150, 156 and 150, and three I term settings changed to take the bounce out of a stop: iterm relax cutoff 10, iterm relax RPY_INC and a yaw pidsum limit of 500. Slow to answer the stick was the most ticked box on the feel form, on 23 reports, and bounces back after a stop was ticked on nine.
• In the sim's own stick test a flick reaches 90 percent of its roll rate 3 to 5 ms sooner. A full stick roll or pitch stop comes back about half a degree, where it came back 1.2 and 1.6, and a yaw stop at three quarter stick comes back 4.6 degrees, where it was 7.8.
• The Tune row still says Betaflight default, with a note saying what changed. Personal bests on the default tune start again, because the record key follows the tune, and laps flown before stay under their old key. The board ranks on the clock and never sees the tune.

Screen and lag

• The low latency canvas was never being asked for. three.js built its own context and dropped the option on every browser. The sim makes the context itself now, and Settings, Screen, Low latency view says whether your browser granted it. It is on by default.
• Auto graphics measures. It lowers resolution a tenth after half a second of late frames and raises it a twentieth after three seconds of headroom, and on the title it can move the preset for a machine that keeps missing or keeps idling. Pick a preset by hand and Auto leaves it alone. The town and built maps follow Render scale and Auto now.
• Predicted view draws the FPV camera where the quad will be when the frame reaches the screen. A frame is on the glass one display period after it is drawn, which at 60 Hz is 17 ms, or 11 degrees of a 670 degree per second roll. It is on by default, in Settings, Screen. It is a setting because you feel it: turn it off if a flip overshoots at the end or the picture jumps when you land.
• Frame pacing is a Settings row: Timer with Low, Timer, always or Display, always. The timer runs the loop without waiting for the display. On one laptop at Low, key to screen fell from 80 ms to 64 at the median and from 144 ms to 80 at the 90th, over nine presses each. It draws about twice the frames, which is heat and battery, and Auto holds still while it runs. Low uses the timer by default, and so does any machine Auto puts on Low.
• Low asks less of the GPU, and the OSD less of the page. Low draws to an 8 bit colour target where nothing reads the extra precision, drops the cloud shading it had kept after losing real shadows, and never draws more than a million pixels. The OSD updates its numbers about 15 times a second and no longer reads the layout every frame.
• Fly, Restart and Resume go fullscreen, and Escape leaves it and pauses. Fullscreen in flight is a Settings row if you would rather not. Input to screen in Settings reads the time from a key press to the frame that first showed it. It is the browser's number, not photons. A feel report carries the flight's frame timings, and its throttle line quotes your own weight and pack: one whoop report read a hover of 39.9 percent when the pilot flew at Weight 70, where it was 32.3.

Fixes

• On a map with no start pads you start in the open, never in a pylon. With pads, you start on them.

Held back

• A radio that reports under about 190 times a second still flicks back a little after a small stop. The fix is in how the sim feeds the controller, and it is not made.

New

• Three partners back WebFPV. Global Drone Solutions is the official training partner, Mantis FPV the official retail partner, and the West Coast Multirotor Club the official club partner. Their marks are on the front page and on Tracks and Times, and painted into every freestyle map. Find one in a map and you get a callout, a panel and 1000 points into the combo. Tracks and Times has a partners page, and Partner with WebFPV is on it and in the footer of the front page.
• The menus are lettered in the manga hand: the wordmark and every room's title, with an ink frame on the panels. The quad on the results page is drawn in ink, with its arms, motors, props and a pod, and the combo tier words are drawn as strokes, so a machine with no Japanese font shows them and not empty boxes.
• Overcast clouds are lit and inked, and tree canopies shade round instead of as a mosaic of triangles.
• On a phone the flight lines sit in the two top corners with nothing in the middle third, and the flight chips fade after three seconds in the air and come back on a touch, on landing or on pause. The Weight slider works wherever it is shown, and pause has a Weight row.

This site

• The front page opens as a manga page: the partners over the wordmark, the headline, and three panels for five inch racing, freestyle and whoop racing. Scroll and the page opens into the film. The town is gone from the film, so the lap goes straight to the map builder. The whoop room in the film is the sakura room. The picture that shows when you paste a link to this site is the first screen.
• The wiki was checked against Betaflight's source. It said that without airmode the motors sit at idle and you have no control, and that the angle limit is about thirty degrees. The mixer fits the throttle either way, and the limit is 60. Five settings that were labelled Works here do nothing in this build, and are Stored, not used. The 103 settings that had no description have one, and Back in the wiki opens the article.

Sticks

• A game controller flies its own sticks in your stick mode. Mode 1 or Mode 2 now reaches a pad, so a controller that had throttle on the right stick has it on the left in Mode 2.
• The help row for a radio whose throttle reads as yaw comes about four seconds after you leave the throttle alone. It had come up to five times late.

The board

• A time goes up at any weight, and says so. The board keeps the weight you flew at and prints "Weight 60%" beside your name on any row that is not 100. Ranking is still on the clock.

Fixes

• Firefox would not start the sim from the evening of the 25th. The page said "The specifier three was a bare specifier". The loader change of the 25th wrote its import map after Cloudflare's own module script had started, and Firefox refuses a map that late. The map is written before the body now, and Firefox starts the sim again.
• Crashes are judged on every physics step, not once a frame. A 60 Hz laptop and a 144 Hz monitor call the same hit the same way, and you are set down where you hit.
• A crash is never set down where the craft cannot take off. One had put a craft under the crane's bottom bar. The crane's foot is solid where it is drawn.
• Tracks: a card is chosen where you click it, and a double click flies it. The page used to scroll after the first click and leave Fly below the fold.
• The drift coupe and the compact coupe were redrawn to read as the cars they are.
• The same opening twice in a row is two passes, not one. On 2022 AU Nationals the lap counts only when 32 to 36 is flown, the loop is flown, and 32 to 36 is flown again.

Held back

• Finding the SubTwoFifty mark is no longer an achievement, and the pill is gone from the map cards. The mark stays painted on every map.

26 September

New

• Cars drive the roads. The builder has a road tool and vehicles, and Play in the preview drives them. A car is a solid that follows its road at the speed its curves allow, and you can hit it.
• Chase a car. The Tail meter builds while you hold its bumper and banks when you peel off. Hitting a car loses the tail and pays nothing.
• Hibari Yard has a loop of two lane road, 7.5 m wide, where a drift coupe drives with a compact blue coupe chasing it. Every car was redrawn, with a face of its own for each kind. Hibari Yard Tandem is the showpiece map: a drift course with two drift coupes in tandem. It is on the board.
• Freestyle maps score the line you fly. Named gaps pay when you go through them. Skims along a wall or a roof, threads between two solids, unders and low passes are close calls. All of it goes into one combo, and a crash drops the whole combo. A low pass pays its points and buys no multiplier. Trick names stay behind the Scoring row in the Freestyle room, which starts on Lines only.
• The freestyle score is lettered in a manga hand, small and out of the middle of the picture. Past 72 km/h ink strokes gather at the edges and lean toward where you are heading, and a crash freezes for a beat in ink. After a scored run the results are a manga page with a share card. Clean FPV and Impact frame are Settings rows.
• Race tracks have a fourth lap count, Practice. It has no end, and nothing you fly in it goes to the board. Lap times are called out loud, in your browser's own voice, and the call follows Volume in Settings.
• Support is a row on the title and pause menus and opens Patreon. Its note gives the tiers: Keep the lights on is $3, Hosting + runway is $8 and Build the sim is $20, US dollars a month. The price came down. A click on Support is counted once, with nothing about who clicked, and nothing is sent if your browser sends Global Privacy Control.
• The Freestyle room lists the board's ten newest maps and pictures the world you are flying. Pause has Back to the track builder on a track or map you built, and Fly this track goes straight to the starting blocks.

The whoop

• The whoop room is recoloured in the sakura theme, lit like a room and not a sunset, with the slap pack stickers as posters and banners on its walls. The logos painted on the floor show on the mat.
• The whoop's OSD has no speed readout. The number was a five inch's ground speed printed over a room built 3.4 times life size.
• The whoop builder lets you delete any side of a gate, one at a time, for a virtual gate that keeps its trigger area, and drag any part of the flight path in 3D to bend it. A pole is drawn as a pole and not a flag, and the square swings on its pole the way it scores.

The board

• RaceGOW rooms rank on the fastest three consecutive laps, and the best single lap sits in the next column. A run that never put three clean laps together is stored and stays off the sheet. The simulator's standings follow the same rule.
• The board refuses laps nobody can fly: none under a quarter of a second, and none faster than the track's length at 50 m/s. Three impossible records came off, a 0.20 s lap round Flags and cones and laps of 10 and 15 ms on Orbit.

This site

• The front page has a freestyle chapter. The map builder puts a yard together, then the film chases a drift tandem round it. A menu after the build jumps to any chapter, and each chapter has a picture of its world as it is now.

Fixes

• On a plain gate the race OSD read "GATE 1 OF 12, SPLIT-S, LEVEL 1". It reads "GATE 1 OF 12" now. The Air slot is airtime from takeoff, not the lap clock, which ran on the pads.
• The Weight card retires by itself: on your first landing or crash, after 8 seconds in the air, or on your first stick move in the air. The Weight slider fades while you fly and comes back when you land or pause.
• The OSD is inked, so PACK, height, THROTTLE, SCORE, AIR and the stick captions read over pale concrete and overcast. Values that were cut off with dots read whole, like Camera angle 30 degrees and Rates as Actual 670/670/670.
• In the builder the racing line no longer leaves a gate and doubles back through it to reach the next. Labels can be switched off while building, the top bar wraps instead of hiding Undo, Redo and the views, and the lap export works when the builder's scripts are cached.
• After a station counts, the next one needs a little flying first, half a metre on the field and less in a room, so on Orbit rocking on the flag no longer counts laps. The builder warns when two stations in a row stand closer than that.
• The results menu no longer covers the run's rows. A plain roll around a rail scores as a Roll or nothing, never a Maverick Loop. A crash on a road puts you on the verge, a little over 4 m from its middle, with the traffic going past. Drift smoke near the eye thins to white and not to ink.

Held back

• Screentone, ink dots in the darkest band at High, is built and off, because the dots swim on the glass.
• The Trick list is still off the title and the Freestyle room.

25 September

New

• You can build a freestyle map. Open the track builder, pick Freestyle, lay a map out from a library of drawn pieces, bandos, cranes and named gaps among them, and press Fly this map. It starts you in the air, not on a menu. Until you build one, Your map is Hibari Yard, a starter yard.
• The screen where you pick what to fly has a fourth card, Map builder. The builder asks what you are building, five inch, whoop or freestyle, with a picture of each.
• Freestyle maps go on the board. Publish from the builder and the board has a Freestyle maps tab beside the tracks. Fly a map from there, or remix it in the builder. Site statistics moved next to Admin to make room.
• Every freestyle map carries the SubTwoFifty mark, painted on a wall you can see from the pads. Finding it is an achievement.
• A link to a track or a map shows that track or map as its picture when you paste it somewhere that draws a preview.
• Site statistics count which site or link a visit came from: the name of the site that sent you, or a ref tag in the link, and never the full address of the page. A tag that is not on the fixed list is counted as other. The privacy panel on the board says so.

This site

• The front page has a short FAQ and a new share picture, and it no longer overlaps itself on a short laptop screen. Every wiki article has its own address and its own preview. Old links with a # still work.

Fixes

• A finger can scroll the menus on an iPhone, and a vertical swipe on the quad picture scrolls the page.
• A town that failed to load no longer leaves you in a room with nothing to press.
• A slow belly first tap on a wall is not a crash. The sim read the wall's direction in the wrong frame, so on some maps a tap counted when it should not have.
• Tags survive a republish. A track lost its tags whenever it was republished without re-ticking them, and whenever the pilot renamed themselves. Publishing goes up as a copy when the board already has the id.
• Every page loads the scripts of the deploy it was served from, so a page and its scripts come from the same deploy. The Publish button had gone missing for one pilot that way.

24 September

New

• The solid world is in the physics. Walls, roofs, gates, trees and the train are solved in the same 1 ms step as the ground, so a roof lands, slides and settles like the street. Props flex and skate along a face instead of levering the frame, and the camera is kept off the glass so it cannot end up inside a wall.
• A crash is a reset, at once. A hit of 4 m/s or more that does not land on your belly sets you down nearby: "Crashed, set down nearby. R restarts the run." You no longer hang on a wall or wait on your back.
• A crashed quad falls flat and ends on its belly or its back. It could stand on a corner at whatever angle it hit. A recovery sets you down on the ground or a roof top, never in the air, which had put a whoop on a room's ceiling.
• The whole wiki is rewritten for a Year 10 reader: all 36 articles, every settings page, the figure text and the glossary. Sections are The idea, How it works and In this simulator, and the chips say Works here, Off at 1 kHz, Stored, not used, Not simulated and Configurator only. Every claim was checked against the simulator's code, which had moved on: two aircraft, a 0.71 kg five inch, contact inside the physics module, and turtle on T. The ground page follows tumble flat.

The whoop

• The whoop is heavier by default. Weight 100 on a whoop now flies what 125 flew, because a pilot flying the same track in another sim had to take it to 120 to 130. The slider tops out at 120 on the whoop, and whoop bests carry over. The five inch is unchanged.
• The whoop reads 1S and 4.2 V. It said 25 V at the start of a race. Only the label changed, not the physics, and its screens stop calling it a five inch.

Sticks

• On the keyboard, letting go of the throttle keys holds height. The throttle springs to the hover for your cap, aircraft, weight and pack, where it had sprung to a fixed low value and dropped the quad. M switches between Angle and Acro.
• Settings, Sticks, Restart switch, with a radio: choose it, flip any AUX or press any button, and from then on flipping it does what R does. It is kept per radio.
• When a browser reads your radio's throttle as yaw, the title says so. The joystick picker draws what the page will fly, not a gamepad's axes.

The board

• The Statistics tab reads plainer, and its sponsor plate is gone. The all time strip drops named pilots and pilots back another day.

Fixes

• The first flight on the new walls found three faults. The town sat at "still loading" for 47 seconds, so its modules are preloaded now. A quad stuck on a wall face, or on its back, is set down nearby.
• A feel report carries what the flight measured, not what the pause screen shows.

22 September

16 to 22 September

New

• Patreon is under the WebFPV name on the title screen, and in the bar on this site. Keep the lights on is $5, Hosting + runway is $12, Build the sim is $25. US dollars, plus GST when you join.
• There is a weight slider on the flight screen. Right is heavier, so the quad drops when you chop the throttle. Left is lighter and it hangs. Normal sits at ninety percent of full Sinky, which is where flying it to the stop felt about right, with room either side. The old slider changed drag, how far the quad carries, and a lap line could print "air at undefined percent".
• Rates are saved in this browser, throttle cap included, and you can keep more than one set. Open them from pause. Changing rates in the air used to restart the run and drop you on the ground.
• Stick mode is Mode 1 and Mode 2, on a radio, a game controller, or the keyboard.
• Tracks and Times has a Statistics tab. Crashes are in it. A crashflip is left out of the flight time.

The town

• Gaps that looked open were solid. A ceiling was missing between two buildings, a hip roof had no peak, and a roof deck you could see was a lid.
• The bridge deck had a slot in it. The canal was solid. The mountains were hollow and the bore had no roof. Four bushes were sitting in the air on a crest. The cafe tables were 1.6 m past the rail.
• Hit a wall and you bounced between two spots until you restarted. The props were pushing you into the face.

Sticks

• A game controller's throttle springs back to centre. The sim read that spring as a punch, and the quad took off by itself.
• The calibration wizard says what it is waiting for. You can finish it with the throttle held down, and a four-axis radio can finish it. A three-position switch is no longer asked to return to a centre it does not have. A gimbal that rests a little off centre keeps that rest, so the quad does not creep with the sticks let go.
• One channel ran backwards, the sticks were on the wrong hands, and a stick stayed down after you let go. The camera angle slider was moving the quad.

Fixes

• The settings room is called Settings. The menus were sending you to a calibrate screen that was not there.
• Menu rows slid out from under the pointer. The help note was changing the height of the row.
• A frozen picture says what it is waiting on.
• The board's crash count read zero. It only heard the clip-through catch, and missed a real hit. Race and freestyle now use the same line, and a turtle after that hit is not counted again. A visit's country was coming through as Unknown.
• The empty-board sentence was showing up when the board had failed to load, tracks and all.
• A rate preset with no id showed in the list and could not be loaded or deleted.
• A feel report now records the sticks as well as the tune. Five reports that said twitchy, stiff, floppy or soft were two phones, a keyboard whose held key only reached about a third of the stick, and a RadioMaster Boxer.
• Tune is one list, in the Quad room. Two old tunes came off it, and the aircraft picker is in that room.
• The flight music lost three tracks and gained five. The wiki was saying the same thing twice on a page.

Held back

• The trick list showed one trick, the wheel did nothing, and the panel stuck on the first row. It was also naming tricks wrong. Both doors are gone, the one on the title and the one in the Freestyle room, until a flown trick gets the name you flew.

15 September

13 to 15 September

New

• The whoop has its own motors, weight and camera, and it parks about a centimetre off the floor. The screens had been calling it by the five inch's name.
• Whoop racing started as four rooms, then the RaceGOW Season 5 tracks went in, each named for the person who drew it. A room card plays the lap. Track 6 is MrE's, the first with no sill. Track 7 is FPVBean's.
• Dive gates in a whoop room stand on a short pipe. You can fly a gap in the frame.
• The board names the person who built the track, and you can search for them. The mark in the corner of the board goes back to this site.

Fixes

• A whoop room could not be finished. The scoring square on a pole was in the author's metres, so a clean pass did not count.
• Tracks 1, 3 and 4 on the board were still the old layouts. They were replaced in place and the times stayed. Track 1 had also been mirrored, so the lap ran the wrong way round.
• Brushing the floor no longer fails a gate. Being on your side does. The bottom third of a whoop gate was marked dirt and refused.
• The whoop's hit box hung under it, canopy and all, because the body size was read as a radius. It is a width. The ducts are drawn, and a pole's foot is solid.
• Gyro noise was scaled to a five inch motor. In a hover the whoop buzzed several times harder than the big quad at full throttle, and the floor was handing it free lift.
• The whoop was on the five inch's tune, in a room that had grown to fit the big quad. The tune follows the machine. The card says which aircraft you are on.
• Posting a time still finds the track if the board has given it a new id.
• The racing line was going through a gate it was not scoring, and a steering rule was pushing it off Track 7. Tracks 3 and 4 were retuned off the animations.
• A gate stands up or it lies flat. One build had added a third pose, half tilted, that no track uses.

8 September

8 to 12 September

New

• The Track room lists the board and the tracks in this browser, shipped rooms included. A card plays the lap from a three-quarter view at one pace, so a longer lap is a longer clip.
• More, in the builder, writes a looping animation of the lap. The racing line can close on the first gate, with the start pads left out of it.
• Whoop gates are 28 inches. Tracks 5 and 8 were rebuilt to that. Six guessed tracks, which were never the real rooms, came out.
• Back is a row, so the corner is clear. The name on the music control is the mute. The bug button is on every screen except the title. A rename of that button had left it dead anywhere a browser still had yesterday's script.
• The film's indoor lap is RaceGOW Track 1. The five inch on the front page reads 6S, which is what the instrument says. The stickers are slapped on.

Fixes

• The racing line was going wide around a stack and through gates that were not in the order.
• The loading bar sat at fifteen percent, then jumped to done. Building the world is most of the wait, and the bar had nothing to report for it.
• Whoop rooms had floor paint and gate numbers. Those are gone.
• An admin can take a track off the board. The whoop list is named for the aircraft.

1 September

30 August to 7 September

New

• Freestyle scoring has three positions, and Off is the one you get until you pick another. Free flight names the tricks and posts nothing. A two minute run can go to the board. The row says the scorer is unfinished.
• There is a training field north of the works, five skills, and the bars are solid. They had been drawn and then never made it into the collision.
• Freestyle is the town. The front page flies that town and ends over it. It had been a painting of the town, and a bug was moving the real one twice, which ate the shops.
• The board has a freestyle side next to the race times.

Fixes

• A Split-S was scored as a Half Matty. A single orbit scored as nothing, then as a yaw spin. A street of posts shut the scorer off for the whole run. The training mast was not an obstacle, so nothing flown around it could count. A wall tap stuck because the direction ignored the way you had spawned.
• Any rail was treated as a pitch, which invented flips. The lap sum in the real sim was backwards. A Maverick Loop paid 250.
• The intro camera stayed on after the quad had left the ground, including on a throttle that never crossed the old takeoff line. Ending the shot was also undone by the next line, so the intro came back. Boot stopped waiting on a board that was asleep.

Held back

• Powerloops, mattys, split-S, immelmanns, orbits and wall taps were being named in this week. The list is hidden as of 22 September.

22 August

22 to 30 August

New

• Turtle. A crash can end on the props, and you flip back over from there.
• New places: the municipal baths, The Kiln, a dressed Industrial bando, Bardwell's yard, the cement works. Blossom is back over the works road.
• A ghost to chase, your best lap or the one before this one.
• Credits name the people who flew it. The FPV wiki is on this website. The next flag glows on the side you pass, and the others stay dark.
• The menus work on a phone and a tablet. A radio with no buttons can still press a row.
• Arcade or expert while you fly. Camera out to 115 degrees. Resolution and a frame cap for a machine that is struggling. Throttle mid and expo are rows on the rates screen. They were already live in the firmware.
• The front page asks if you want to fly, once, in the middle, then leaves the offer in the corner.

Fixes

• Takeoff was a crash. The bang at the start line was two bugs. An upside-down gate, or a bounce off the dirt that came back upright, finished the lap. Grass is a dead thump. A hard hit flat on the base stays down. A small tap you fly out of. Turtle snaps upright when you ask.
• First flight was swapping the track you opened for the old race field.
• The overbridge stairs are flyable. The colliders sit on the treads. The cage is open. Gaps between posts stay gaps. Cover had been filling them. Parked cars were lifting into the air above their roofs. The pavilion is a shell, the bins are a line, a tilted dive stands on two posts, and the racing line no longer detours out to the pads.
• The baths hopper is a cellar. The cement works is one machine, and what you hit is what is drawn. The bug chip covered the track name. The mouse could not leave a map. A mirror was blocking a gate.
• Menus jittered because the bold label changed width under the cursor. The title note drew on top of the keep note. A failed boot says what to do. The bug report keeps what you typed. Music starts on a different track each visit.
• Yaw was climbing, partly from one rotor. Prop wash had been turned down until it was gone, and a pilot said so. The five inch picked up the weight on the scales. A Precision tune went in for a feel report that asked for one.
• If the board's config request failed, every link on the page broke. Credits on the board open the simulator's credits page. A pole on a plan is drawn as a pole. A fly link carries which aircraft the track is for.
