As of Betaflight version 3.3.0, the CLI settings below can be used toconfigure addressable video transmitters (such asTBS-SmartAudioandIRC-Tramp)that are connected to the flight controller.At startup the settings are applied to the transmitter. If the videoconfiguration is modified via the CMS OSDmenuor via MSP (Taranis/OpenTX smartport'lua'), thesettings are updated.One nice thing the settings can provide is a way to configure afrequency (via USB / CLI) while the video transmitter is not poweredup. After a save and power cycle, the system will startup at the newfrequency.There is a 'vtx_freq' setting that operates as follows: Ifvtx_band=0 and vtx_freq!=0 then the 'vtx_freq' value (in MHz) will beconfigured on the transmitter at startup. If both are zero then thesettings will be ignored. If vtx_band!=0 and a video transmitter isconnected then 'vtx_freq' will be set to the current frequency value(in MHz) at startup.\noteValues for settings like vtx_band, vtx_channel, vtx_power are relevant for Betaflight versions prior to 4.1 which had these default values built in. In Betaflight 4.1 and newer to control your VTX you must configure a VTX Table in which you define your own bands, channels and power settings based on local regulations.vtx_band = #Allowed range: 0 - 50=user, 1=A, 2=B, 3=E, 4=F(Airwaves/Fatshark), 5=Racebandvtx_channel = #Allowed range: 1 - 8vtx_power = #Allowed range: 0 - 5for SmartAudio: 0=25mW, 1=25mW, 2=200mW, 3=500mW, 4=800mWfor TBS Unify Nano: 0=25mW, 1=25mW, 2=50mWfor IRC-Tramp: 0=25mW, 1=25mW, 2=100mW, 3=200mW, 4=400mW, 5=600mWvtx_low_power_disarm = ON|OFFIf ON and the flight controller is disarmed, the video transmitter output power will be set to its lowest value (vtx_power=1).

Betaflight supports different rates models. A rate model is the mathematics used to transform the stick position to a turn rate in deg/s. Three parameters, RCRate, Rate, and Expo, determine the curve of the rate model.Typically the maths makes the sticks less sensitive in the center and more sensitive further out.The pilot can adjust their Rates to suit their flying style. Typically:racers prefer a more linear curve with a maximum turn rate of around 550-650 deg/sfreestyle typically uses a combination of a soft center region with high maximum turn rates (850-1200 deg/s)cinematic flying will be smoother with a flatter center region.It takes time to get accustomed to a change in rates. Don't rush.Betaflight supports Actual, Quick, Betaflight, Raceflight and Kiss models.Metamarc's rate converter is probably the best converter and visualiser, supporting all the Rates models currently available in Betaflight.Actual Rates"Actual" rates, by @ctzsnooze, were introduced in 4.2 and became Betaflight's default in 4.3. The older "Betaflight" rates model is still supported, with . In Actual rates, the center sensitivity and maximum rate can be directly entered in deg/s. The expo setting shifts the kink point of the curve, without affecting center or max rates. Each parameter is completely independent of the other.To compare Actual with Betaflight rates, there are charting solutions by:metamarc.com - probably the bestctzsnooze on Desmos (has all the maths, difficult to use)kmitchel (seems to be broken).For more information about Actual rates, see:4.2 Tuning notesGithub PR 9495Github PR 9506Quick RatesQuick rates, by @illusionfpv, allows the user to set center sensitivity as an independent value, and the Expo and Rate values interact with each other to determine the nature of the expo curve and the maximum turn rate.To convert between Betaflight and Quick Rates:illusionfpv.github.ioBetaflight, Kiss and RaceflightThe maximum rate and center sensitivity of Betaflight, Kiss and Raceflight rates modelsRelease Betaflight 4.4.0 betaflight/betaflight - GitHub
RequirementsBetaflight - As a best practice, it is recommended to use the most recent stable release of Betaflight to obtain the best possible results;Telemetry - Telemetry has to be enabled in Betaflight Receiver tab and supported by the TX / RX for the scripts to be able to communicate with the flight controller;OpenTX - 2.3.12 or newer;EdgeTX - 2.4.0 or newer;ExpressLRS - 2.0.1 or newer;TBS Crossfire/Tracer TX / RX - v2.11 or newer;FrSky TX / RX with support for SmartPort - While most receivers with SmartPort support work fine, it is recommended to update the receiver to the most recent firmware version to correct any known bugs in telemetry.ImmersionRC Ghost RX module - Latest firmware and module set to RF Mode "Race250" - see (Ghost receiver manual pg 36-38) (Other RF Modes have issues or do not have telemetry to allow Betaflight LUA to work).Baud rate - Set to 400K in EdgeTX/OpenTX for Crossfire, Tracer, ExpressLRS.Installing!!

BetaFlight a couple times and now I can make the motors spin....Unfortunately, now I can't make them stop spinning, even when not armed and disconnected from CleanFlight, they keep spinning.Second opinion say might be a defective FC. I'll keep at it and thank you for taking the time to reply. Vendor is sending new Ipeaka ONESHOT125 ESC replacement.I removed BetaFlight and started with OpenPilot again, flashed the firmware, went through vehicle setup and have been able to configure the quad. So the FC is working, just not with BetaFlight at the moment. I must be settling it up incorrectly in CleanFlight. I'll wait till the esc arrives then I'll go at again. Almost 2 weeks into it, and I can not figure out why cleanflight/betaflight wont work on my build.Can anyone help?I have put together a 210mm quadcopter with OP CC3D/ Ipeaka 15A ONESHOT125/ 2204 2300kV motors. After I assembled parts together, I used OP to configure and test quad. It arms, spins motors, communicates with X9D+ using SBUS connection/ FrSky X4R-SB.Went ahead and flashed Betaflight 2.5.0 (and i have tried every betaflight since 2.1.0) since im using BF on my other CC3D quad, and tried to configure using cleanflight. I leave ONESHOT on, stop motor spin off, serial connection, sbus, min thottle at 1000, mid 1500, max 2000, rssi on. I am able to configure Taranis to communicate with CleanFlight, and the moment i hit save (quad is powered since it needs to be powered to get radio communication), the motors start spinning. If I hit disconnect and remove usb from macbook, motors continue to spin. I have to unplug battery to stop motors. When I try to calibrate ESCs, I switch test on and move master all the way up, plug in battery and ESCs only make a short sound. After that, if i try to test motors, they do not spin. The only way to make the motors spin is to hit save on Receiver tab, or Modes tab, or Configuration tab...anywhere you can hit save. ...Is there a selection that I am suppose to switch? Is there a CLI command that I am suppose to enable? I do not have a clue. Turn off One Shot and see if it works as expected. Have you verified that moving the sticks on your taranis results in the correct inputs to the board from within clean flight? Quote: Originally Posted by rocketsled666 Turn off One Shot and see if it works as expected. That is GREAT!!! I turned off ONESHOT and it arms and works...although, it seems like there is lag in the input. Is that normal? So I take it there is no more active braking?

Joined Jul 6, 2021 Messages 5 Reaction score 0 Age 21 #1 Hi, I have (almost) successfully finished my first build. I have a 5 inch quad with a matek f722-px and a sharkbyte txs.5 as vtx. I have set up everything as it was described in the manual and everything works as it should except for the OSD. I have already flown the quad and I was so stressed out that I didn't even notice the OSD not being there. But now I'm trying to fix it and nothing helps. I enabled the OSD in the configuration tab, I haven't switched the tx and rx wires, in the ports tab ther is nothing wrong too. The one thing I haven't tried is switching the camera format from ntsc to pal or the other way round, because this setting doesn't show up in betaflight. I have installed betaflight again on two other computers and it still doesn't show up. Now I don't know what to do, because I don't really want to fly longer than 1 min and 30s, because I can't see the battery voltage.In the picture below is everything I see in the goggles.Thanks for any help Attachments Bildschirmfoto 2021-09-13 um 11.30.50.png 1.8 MB · Views: 6 mrmund Well-Known Member Joined Aug 26, 2020 Messages 181 Reaction score 110 Age 49 #2 I'm not sure if this is a Sharkbyte thing but with other cameras I've had to change the PAL/NTSC settings on the camera itself to see the OSD Enzoboomin New Member Joined Dec 28, 2021 Messages 1 Reaction score 0 Age 25 #3 Hi, I have (almost) successfully finished my first build.
