Dshot is new and currently code is being developed and tested. Since there are many dependencies and not all current hardware works this is to help keep track. The First Post of this thread has all the needed Links to code and other info.

BetaFlight V3. The Latest Development version of the Configurator is recommended. Link on Home page. Go to the CLI and type "get pwm". All settings with 'pwm' in the name will be shown with all options. Note: In Firmware 3. This got fixed in 3. Be aware that Dshot ESCs can run motors at much slower speeds but if idle speed is too low the motor may Stall in flight during hard maneuvers and you get a 'death roll'.

Ok first Point - dshot does not use min and max throttle, you don't need to do that. Second point - when not using min and max throttle you should calibrate from bf, not manually set in blheli. So let's deal with your question. To check what value digital idle should be set to, connect to configurator, go to the motor tab, take your props off. Click the little check box half way down the page that says you have taken your props off, you know what you are doing, you take full responsibility for your actions and you consider fingers pointless appendages anyway.

Click on the master slider and use the up arrow on the keyboard to increase the master slider one point at a time until you reach a point where all 4 motors have just started to spin, I don't mean twitch, stutter or start stop, I mean the lowest value where they are spinning, it is probably aboutdon't worry if it isn't, but I am going to use that number as an example.

Take the number for example purposes and add thirty points to it so in the example we are now at Not we need work out what percentage of the throttle range this is, I don't know your math skills so sorry if this is a little hand to mouth.

Subtract from it, then divide by Replace 4 with whatever digital idle you arrived at in the calculation Hit return, you will see the command processed in the back bit above, Then click in the box again and type.

Theoretical speeds are a lot higher. The speed is limited in firmware to give more spreading between signals. What should I check first? Then I've been going back to DShot and setting things up normally. Don't ask me why or how it works, but I've had to do this on more than one occasion now or I get a distant ESC song or two playing out of sequence in the background like you have now.

This worked each time, but not saying it will work for you with certainty. They should surely work if the FC was designed for them. You will need to re-map a motor to a Servo for a Tri-copter. The information posted herein is all provided on an AS-IS basis.

Betaflight may not be able to support all Targets or specific boards due to the design of each one differing on the DMA pinout. Look below to find what may or may not be working. It may be that we will assign one of the motors to PPM pin so you can resolder it. Not great, but better than nothing I guess? Click Save. Leave this select until pins are re-mapped. Move the motor 2 wire to the PPM pad at the bottom of the board.There is so much new stuff to learn in Betaflight 3. In this tutorial I will try to explain how I tune my quad with the latest Betaflight firmware in the simplest way possible.

This guide has been updated for Betaflight 3. The official tuning guide for Betaflight 3. It also explains the new changes in Betaflight 3.

Check out this article to see what Feed-Forward does. Here is how you tune it:. If you want sharper response and more control, increase F gain. If you want smoother stop of a flip and less prop wash, increase D gain. If you have oscillation on Yaw axis, you can try higher F and I values, then drop P to maintain the responsiveness while keeping oscillations caused by P gain to a minimum.

Apparently not only too much P and D can cause bounce-back, I gain can too! Throttle Boost is a bit like a dynamic throttle curve, it exaggerates throttle changes.

Make some rapid throttle movements when tuning this value. You want to land on a number where you get very responsive throttle without surging, overshoot and feeling over-sensitive. Heavier quads, and quads with weak motors need higher Throttle Boost value.


Stepping in the RC signal results in rougher running motors. RC Smoothing filter can smooth out these stepping. It can even reduce spikes and sharp edges from rapid stick inputs, your motors will run smoother and cooler. In Betaflight 3. The benefit is that the aircraft feels more responsive and connected to your sticks. This allows faster channel update by not sending the 9th to 16th channels 9ms vs.

There are now 4 low pass filters, 2 for Gyro and 2 for D term. These are all enabled by default.The timeline for the release of Betaflight 4. The release is planned for 1 May If you are planning to contribute code to Betaflight 4. We're already late, so let's keep this short!

As you've come to expect, we've packed this release with a whole lot of new flying goodness, new features, and support for a bunch of new targets. We know we are overdue again for Betaflight 4.

But there is something you can do right now to make sure you are prepared for Betaflight 4. This will get you all set to install the most current Betaflight firmware once it is released! For Betaflight 4. Unified Targets have been used successfully by testers since Betaflight 4. But we were still not happy When we released 3. It became clear that we had to do something. We had been working on changing the architecture of Betaflight to make it possible to use the same firmware for different flight controllers for some time, and so we decided to complete this change before releasing the next version, and that because of this fundamental change the next version would be 4.

As we approached the originally set release date for Betaflight 4. For a while now, development of Betaflight for flight controllers based on the STM32F3 chip has been hampered by a severe limitation that this chip has. As announced earlier, Betaflight 4. As you might have learned from the Betaflight GitHub page, our next release will be 4.

Betaflight 4. Latest News What has been happening in the world of betaflight? Read More. Get Ready For Betaflight 4. End of active development for STM32F3 based flight controllers 02 Apr For a while now, development of Betaflight for flight controllers based on the STM32F3 chip has been hampered by a severe limitation that this chip has. New requirements for the submission of new and updated targets 01 Apr As announced earlier, Betaflight 4.The goal is smoothness.

If used with 6S quads or lighter weight freestyle quads, cut the PIDs by about a third before trying to take off. It may otherwise shake and head to the moon! Test by increasing the value in the CLI to confirm that a higher value makes it worse, then try progressively lower values until it no longer bothers you.

The optimal value is the highest value that doesn't give you the bounce-back. The snippet above should be sufficient for most freestyle machines. This isn't usually an issue for cruisy freestyle flying, but is a big problem for race pilots or people who push the freestyle envelope a bit.

Race pilots usually prefer setpoint with the cutoff atand accept some bounce back. Here the goal is responsiveness, lots of I, the least D possible to better handle bent props, with propwash and flip control of lesser importance. For 6S quads you should first cut PIDs by about a third. The settings below cut D a lot and P a bit, and filter D a bit more strongly lower down. Betaflight 4.

Try the following, which allows the dynamic notches and low passes to go low enough for these lower rpm setups:. RPM based multiple notch filtering should be great for these machines.

The snippet below configures the 4. Provided you have a really good tune in 3. Latency will be slightly reduced at higher rpm and motors may be a little bit cooler, but overall it should be much the same.

Try these settings if you're having trouble getting a good result in 4. YAW I-term is 2. To exactly match 3. Reversed airflow generates tip vortexes that greatly reduce thrust. Whenever we cut throttle in a reversal, any motors that start at zero throttle will be much slower to spin up than the others, leading to very unequal thrust development, crosstalk between axes, secondary PID reactions, and worsening the instability.Made it simpler with more links to outside guides for specific content.

If you wish to view our old Betaflight 3. This guide is part 2 of our Drone software setup series. The tricky thing about this process is that flight controllers these days have more than a hundred different options that you can enable and configure.

If this is your first time flying a miniquad, this is exactly what we recommend you do.

Keep it simple at first, establish a flying baseline — then add extra features. If you are using a different set-up, certain parts of this article may not apply to you. We have linked the relevant sections from the BetaFlight documentation for this purpose. Even if you are not using a different set-up, we highly encourage you to follow these links and learn from the mouth of the developers who brought you this amazing software.

To do any work on your quadcopter, you will need to install Betaflight Configurator. This is a desktop application that is available for Windows, Mac, Linux and Chrome. It used to be a Chrome browser application, but is now distributed independently from Github. You can read how to install it in our Betaflight Configurator installation guide.

If you just want the download link, it is here:. Note that Betaflight Configure is tightly bound to the Betaflight version you are running. You must update Betaflight Configurator when you update your Betaflight firmware on your flight controller! Failure to do so will often result in some very strange bugs. Before you do anything, we recommend you make a backup.

This will allow you to stash away the default settings for your quadcopter or flight controller so that you can restore them if you totally screw it up somehow by following the steps below. This is a handy feature that was added to reduce the number of visible features from first time users. This includes using some of the features hidden by this checkbox. Most flight controllers with their own firmware will have the correct box already checked. Read more about ports from the Betaflight Serial documentation.

In this tab, we do basic configuration of the various features you want on your quadcopter. As discussed above, we recommend you set-up the bare minimum.

And if you scroll down —. The flight controller will reboot, you may need to manually re-connect Betaflight Configurator. Many flight controllers these days come with a built in PDB that automatically hooks up battery voltage VBAT readings and often current readings.Fortunately there is a largely undocumented feature which might help. When making any configuration changes to your quadcopter, it is recommended that you remove the props to avoid potential injury. Also ensure that you have a battery connected to the quadcopter and your transmitter turned on.

For sprung gimbals such as roll, pitch and yaw, the midpoint values when you release the gimbal should be If your figures do not match the above recommended figures then you will need to make some adjustments as follows. If only minor adjustment is required e. You may find that your transmitter does not allow you to exceed a certain value when adjusting sub-trims, the FrSky Taranis X9D has an inbuilt limiter which can be set per model.

If the values shown in CleanFlight or BetaFlight are dramatically different to the recommended values of e. This feature is documented in the BetaFlight FAQs but there are very few practical examples of how to utilise this useful command.

For each of the primary channels shown in CleanFlight or BetaFlight, note the lowest and highest figures — for my setup, the lowest wasthe highest was For example using the figures in our example, we would enter:. They should now read and respectively.

It might be necessary now to use the transmitter sub-trim features as described in the first section of this article to fine-tune the top and bottom values, as well as to correct the Mid-Point value which must be set to We hope that this guide is useful, please feel free to comment below with any corrections or omissions.

This fork differs from Baseflight and Cleanflight in that it focuses on flight performance, leading-edge feature additions, and wide target support. The timeline for the release of Betaflight 4. The release is planned for 1 May If you are planning to contribute code to Betaflight 4. We're already late, so let's keep this short!


As you've come to expect, we've packed this release with a whole lot of new flying goodness, new features, and support for a bunch of new targets. Betaflight supports nearly all flight controllers on the market having at least an STM32F3 Processor. Not even less-related components stay untouched, so Betaflight allows to control VTX and Camera settings directly through the flight controller.

There is so much support out there for betaflight users. Don't know where to look? We have compiled a list of our favourite resources. Originating from baseflight and cleanflight, betaflight continues to live the idea of open source. Everybody having precious ideas is welcome to implement them for the main product. An easy to use drag-and-drop configuration allows to place values like used mAh and LiPo Voltage readings. Additionally you can change most firmware settings using stick commands wihtout even removing the goggles from your face.

Mini-drones are dangerous toys. As incidents with suddenly spinning props often end bloody, Betaflight implements several safety features to prevent dangerous behavior. Betaflight not only strives to put the best flight code on your controller. Also it satisfies requirements as perfect performance, tiny footprint, newest features and a strong quality assurance process.

All flight related data can be logged into a blackbox for later analysis. So pilots and techniciants can base finest tunings on objective data. Don't know where to start, this video is for you. The basics all wrapped up into an easy to watch tutorial. Latest configurator releases. Releases can be found on github.
