Betaflight Rc Rate Super Rate Expo Pid

Welcome to this comprehensive tutorial, where we will explore the intricacies of Betaflight Rates (RC Rate, Super Rate, and Expo) as well as Actual Rates (Center Sensitivity, Max Rate, and Expo). Moreover, I will share my personal insights on how I adjust my rates to accommodate various flying styles and applications.

Fine-tuning your rates is as critical as tuning your PID and filters when it comes to optimizing your Betaflight FPV drone’s performance. You’ll be amazed by the significant improvements you can achieve in your flying experience by tailoring rates to match your unique flying style and requirements.

Betaflight offers a total of five rate systems:

  1. Actual Rates
  2. Betaflight Rates
  3. Raceflight Rates
  4. KISS Rates
  5. Quick Rates

However, the most widely adopted are Actual and Betaflight Rates.

In this tutorial, we will delve into the key features of Actual and Betaflight Rates, how they function, and how I personally fine-tune them. It’s essential to select a single rate system to work with, and my recommendation for beginners would be to start with the default – Actual Rates. It also works well for experienced pilots.

Understanding Actual Rates

“Actual Rates” are the default rates in Betaflight, providing a straightforward approach to setting maximum rotational velocity (e.g., entering 1000 corresponds to 1000deg/sec) and center sensitivity values. No more guessing, as this system is far more intuitive and less confusing for pilots compared to the older Betaflight rates.

If you are new to the hobby, I’d recommend using Actual rates. If you come from another type of rates, there are many online rate converters that allow you to switch between them.

There are 3 values in Actual Rates: Center Sensitivity, Max Rate, Expo.

Center Sensitivity

Betaflight Actual Rate Center Sensitivity

Center Sensitivity relates to the responsiveness around the center stick position. A lower value offers finer, smoother control, while a higher value results in a more reactive drone to stick movement.

Max Rate

Betaflight Actual Rates Max Rate

Max Rate defines the drone’s spin speed at full stick deflection. The value entered represents the exact maximum rotational velocity. For example, entering 700 means your drone will attempt to rotate at 700 degrees/sec at full stick.

However, keep in mind that the maximum angular velocity can be limited by your motors. When motors reach their physical limitations and cannot spin any faster, the maximum angular velocity is capped, regardless of the higher value set in Betaflight.


Betaflight Actual Rates Expo

Expo flattens the curve between center stick and full stick. To achieve a more linear rate, keep Expo low. For a broader center stick region with finer control, increase Expo. Keep in mind that increasing Expo also reduces center sensitivity. While Expo can be as high as 1.0, excessive Expo might cause decreased center stick sensitivity and make the drone’s response more unpredictable towards full stick (more jumpy).

Tuning Actual Rates

Start by setting the Center Sensitivity. Cruise around and navigate through gaps to test the desired control precision around the center stick. For small adjustments and precise aiming through gates and gaps, the drone must be precisely controlled. If the Center Sensitivity is too high, the drone will overreact and become jittery.

Next, establish your Max Rate by performing flips and rolls. This step should be relatively straightforward.

Lastly, practice freestyle moves involving various stick positions between center and full stick. To flatten the rate curve, add some Expo, but be aware that this can reduce predictability towards full stick. If you increase Expo, you may need to raise Center Sensitivity slightly to compensate. Expo is primarily a matter of personal preference.

A useful tip: try a higher Max Rate for Yaw, reducing the need for significant Yaw stick movement. This approach can help with throttle management, as excessive Yaw stick movement might make it challenging to manage.

My Rates

Here’s a general guideline for different flying styles and applications based on my personal experience:

  • Cinematic: 50-150 Center Sensitivity
  • Freestyle: 100-200 Center Sensitivity
  • Racing / Line of Sight: 150-300 Center Sensitivity

Then set Max Rate according to your flying style:

  • Cinematic / Racing: 500-800 Max Rate
  • Freestyle: 600-1000 Max Rate
  • Line of Sight: 1000+ Max Rate

My Freestyle Rates


  • Center Sensitivity: 190
  • Max Rate: 1000
  • Expo: 0.70


  • Center Sensitivity: 200
  • Max Rate: 650
  • Expo: 0.55

Note that my rates differ depending on how I hold the sticks. When “pinching”, my rates are similar, but center sensitivity tends to be higher because I can move the sticks more accurately compared to when I’m “thumbing”. Personally I normally pinch, but here’s my rates when “thumbing” for comparison.

Pitch/Roll (Thumb)

  • Center Sensitivity: 140
  • Max Rate: 1000
  • Expo: 0.50

Yaw (Thumb)

  • Center Sensitivity: 180
  • Max Rate: 650
  • Expo: 0.40

My Tiny Whoop Rates


  • Center Sensitivity: 230
  • Max Rate: 1000
  • Expo: 0.62


  • Center Sensitivity: 250
  • Max Rate: 1300
  • Expo: 0.68

Notice my yaw rate is a little higher because I use a lot of yaw when flying my whoops indoor due to the amount of rapid sharp turns.

Delving into Betaflight Rates

Betaflight Rates, unlike Actual Rates, are slightly more complex as the three terms are interdependent, making them less intuitive to use. However, as the oldest rate system in Betaflight, many experienced pilots continue to rely on them.

RC Rate

RC Rate affects the rate curve’s slope linearly throughout the entire stick range and determines how quickly the quadcopter rotates at full deflection. If you’re familiar with computers, you can think of it as mouse sensitivity.

A higher rate results in a more responsive but twitchier quad. Small stick movements will produce significant quad movements. Increasing the RC Rate also boosts the quad’s spin speed, enabling faster flips and rolls.

Betaflight Rc Rate Angular Velocity

However, keep in mind that the maximum angular velocity can be limited by your motors. When motors reach their physical limitations and cannot spin any faster, the maximum angular velocity is capped, regardless of the higher value set in Betaflight.

RC Expo

RC Expo, also known as Exponential or simply Expo, reduces sensitivity near the stick’s center where fine controls are needed (for Roll, Pitch, and Yaw) but does not change the maximum angular velocity at full stick.

Expo is a percentage value, ranging from 0% (0) to 100% (1). At 0%, the increase in rotational speed between minimum and maximum stick input is linear, forming a “V” shape with no stick input in the center. At 50% stick input, your quad will rotate around the given axis at exactly half the maximum rotational velocity.

Betaflight Rc Expo Curve Slope Center Stick Sensitivity

Increasing Expo reduces sensitivity around mid-stick, requiring further stick movement to achieve the same rotational velocity. Visualize Expo as transforming the “V” shape into a “U”, with a higher expo percentage flattening the “U” around the middle.

Super Rate

Super Rate (or simply Rate) increases both max angular velocity and sensitivity around the center stick.

Betaflight Super Rate Effects

By raising the Super Rate, you can maintain moderate stick sensitivity around mid-stick for standard flying maneuvers while still achieving snappy rolls and flips at the stick endpoints.

Super Rate essentially combines the effects of RC Rate and Expo, allowing for more flexibility in achieving the desired stick feel.

Betaflight Rc Rate Expo Super Rate Curve Effects

So why use Super Rate? We can just use RC Rate and Expo right? Yes, sort of, but having Super Rate gives us more flexibility in achieving the stick feel we want.

Tuning Betaflight Rates

Tuning rates ultimately depends on personal preference and “feel.”

Begin with the default Betaflight values: RC Rate 1.0, Super Rate 0.7, Expo 0 for all three axes.

When tuning my rates, I always adjust RC Rate first. Perform flips and rolls, and if the quadcopter spins too slowly, increase RC Rate until satisfied. Note down the max angular velocity (deg/sec) in the Betaflight Configurator. For my freestyle rig, I usually aim for around 700-800 degrees per second.

Next, simply cruise around (without flips or rolls) and ensure the quadcopter responds swiftly and predictably to your stick inputs during turns. If it’s too sensitive for precise movement, increase Expo. If it’s too slow to react (not sensitive enough), decrease Super Rate while increasing RC Rate to compensate and raise the max angular speed.

Expo isn’t always necessary since Super Rate can provide the same effect. However, if you still find small movements around mid-stick too sensitive, increase Expo until you strike the right balance between precision and responsiveness.

Pro Tip: Applying Expo on the radio (TX) reduces your stick resolution, so always set Expo in the flight controller software whenever possible!

You may need to iterate through the process several times until the rates feel perfect. Remember that pitch, roll, and yaw rates don’t need to be identical—freestyle pilots often prefer higher roll and yaw rates but lower pitch rate, it’s all personal preference.

Different flight controller software has different ranges and scaling in PID, rates and expo, so the same numbers don’t necessarily give the same results in a different firmware. You should be able to find online converters if you want to migrate to a different FC firmware.

To give you some examples, here are the Rates and Expos I used in the past:


  • RC Rate – 1.2
  • Super Rate – 0.77
  • RC Expo – 0.20

Smooth Cruiser:

  • RC Rate = 0.80
  • RC Expo = 0.00
  • Super Rate = 0.65

Expo is set to zero here on purpose, this is to avoid overreacting in close situations and actually gives you overall smoother result.

Aggressive Acro Quad:

  • RC Rate, Pitch/Roll = 1.80, Yaw = 2.00
  • Super Rate, All = 0.64
  • RC Expo, Pitch/Roll = 0.20, Yaw = 0.15

Tiny Whoop Rates

  • Roll+Pitch: RC Rate 1.2, Super Rate 0.75, Expo 0
  • YAW: RC Rate 1.3, Super Rate 0.80 Expo 0
  • If using acro mode, enable crash_recovery, there are some settings (get crash_ in CLI) you might want to tune first to avoid false self-centering.

As your flying skill improves, and you become more comfortable performing aggressive manoeuvres, you could try to crank up your rates. And you will also probably want to use a bit more expo to maintain accurate fine control.

There is no right or wrong Expo and Rate values, as long as it suits you. For example, I have shaky fingers, so my expo might be a bit higher than others. :p


Maintaining consistent rates across all your quads is crucial for developing muscle memory. This is especially true for yaw and roll, as consistent rates enable you to instinctively control these movements. When you switch rates, adapting to the different feel can take some time, depending on your experience as a pilot. Therefore, using consistent rates helps you transition between quads without any surprises.

Throttle Mid and Throttle Expo

Throttle Expo modifies the shape of the throttle curve, flattening it around the “Throttle Mid” point. This allows for a gentler throttle response and maximum stick resolution around this throttle level.

Throttle Mid adjusts the position in the throttle curve where Throttle Expo is applied. By default, it is set to 50% throttle (0.50), but if you plan to use Throttle Expo, Throttle Mid should be set to the throttle of cruising speed. This is where you will need the most throttle resolution, and Throttle Expo might make altitude control easier for you.

Throttle Mid will not have any effect if you set Throttle Expo to 0, as your throttle curve will remain a straight line regardless of the Throttle Mid setting.

Alternatively, you can set up a throttle curve in your transmitter for even more precise throttle control.

Merci Oscar, so well explained , thank you so much !!!

Donal 19th May 2023 - 10:18 pm

Hello.. I calbrated my radio but when i go to sensitivity page, im only getting .80% of throttle.I tried a different radio but the same result. Can you help me get full 100%…My friends are using the same drones and setting but there drones are a lot faster..please help.

Oscar 19th May 2023 - 11:45 pm

First of all, what do you mean by sensitivity page? where do you find it?
And where do you see 80% throttle?

Lee 17th November 2022 - 6:56 pm

Hi Oscar, when setting the Throttle Mid point, you say to set it to the throttle of cruising speed. Is there a way to determine accurately what position that is, or mostly just a guess?

john dewey 15th October 2022 - 6:36 pm

If you are trying to get your cinewhoop to fly with low rates but still be able to do flips and rolls, this is the article you need to read. Awesome. Thank you.

Eric Coogan 13th August 2022 - 4:29 pm

Hey Oscar, my name is Eric. I would really like to speak with you about a project my partner and I have been working on for over a year now and I think it’s finally there. It’s a lot to go over in text. I’d appreciate it if you could give me a few minutes to explain what it is we’ve got. It’s a new kind of drone. It looks like a cinewhoop but flies like a 5 in. We’ve been granted 2 provisional patents for a couple of things on the drone that make it what it is and how it flies. I’m thinking any improvement from his point can be achieved through beta flight tuning. I will tell you everything when we talk. We can exchange info through email if you like. LMK. Looking forward to hearing back from you. Thanks

Aldo 8th August 2022 - 9:32 pm

Is DJI controller fully compatible?
I have a problem for whenever doing maximum pitch forward.
If I go max pitch then it doesn’t stay forward and it changes to backard pitch.

dario 28th May 2022 - 2:16 pm

Thanks man, really helpful text!

Mike H. 10th November 2021 - 1:53 pm

Hi Oscar, the version of BetaFlight I’m on doesn’t seem to have a “SUPER RATE” adjustment column, am on an older version possibly? Thanks.

5li3ret 15th June 2021 - 6:45 pm

Hey Oscar; first of all – thank you so much for the effort you put in this site. It has helped me tremendously!! I have one question regarding the rates. I put my rates in Betaflight 4.2 and no problem with this but then i go flying and when i look into the rate options in the dji goggles and there are different rates then i set in BF4.2. It seems it makes no difference what i do in BF, the dji goggles always show the same standart rate … any idea? Thank you so much!

Oscar 15th June 2021 - 11:41 pm

Make sure you’ve chosen the correct Rate profile in Betaflight? There are 3 profiles.

Jorge Jesus 9th January 2021 - 9:46 am

Thank you Oscar

This has help me alot with the DCL game.

Nmw01223 8th February 2020 - 5:05 pm

I have just belatedly found this useful post after trying to work out what the configurator settings mean.

However I cannot quite see the point of having three settings – rate, super rate and expo? It seems to me that everything necessary could be achieved by two – rate and expo? The rate being rotational deg/sec at full stick movement (linear), and expo ratio of centre stick position slope to max stick position slope (or vice versa)? In the end it is just one transfer function, so cannot see why it takes three settings to achieve that?

Also, I think it might be more accurate to say that applying expo in the FC rather than Tx increases stick resolution at the centre (at the expense of max deflection resolution) rather than doing it in the Tx reducing it. Doing it in the Tx just doesn’t increase it, but it doesn’t reduce it either.

Quentin 24th December 2019 - 2:59 pm

Hi Oscar
Thanks for your valuable blogs.
I’ve been coming back to this article quite a few times over time. Nice reference to have.
Just one thing. Is there a typo in your Smooth cruiser settings?
You have RC Expo, All = 0.03
Shouldn’t that be 0.3? Can’t see how such a low expo will give you smooth cruising?

Oscar 3rd January 2020 - 2:30 pm

For me, expo is to accommodate rate, if rate is low you don’t need much expo otherwise it will make your centre stick way too insensitive. Also Super rate also acts as expo, setting it higher gives you some expo effect.

Rajeev Gopal 10th September 2019 - 6:28 pm

Hi to get a 700Deg which combination RC and Super rates should be given for freestyle flying? And do do smooth flips and rolls. Iam flying 2in micros.

Oscar 10th September 2019 - 6:50 pm

There are endless combination… but This is what I’d use, RC Rate 1.3 with Super Rate 0.65-0.67?

roberto 26th March 2019 - 10:35 am

Oscar, is there any excel file that generates the Rate chart as in BF based on inpunt Parameters: Rate, SuperRate, RCExpo? I’d like to create one but it is difficult to find the correct formulas

Oscar 1st April 2019 - 12:56 pm

Best to adjust this on the actual quad, sometimes the actual response from the quad is slightly different that the numbers suggest in the GUI, because it’s largely dictated by the performance of motors, props, ESC and battery

Renato 28th September 2018 - 10:36 pm

Thank yoi. Why in some quad, the Max Vel Deg/s of yaw is smaller or bigger, despite the rates of pitch, roll and yaw are equal? Thanks

Oscar 1st October 2018 - 4:58 pm

It’s just an estimation, the actual rates of rotation depends on your props and motor, and how good the battery is providing the power.

Martin 10th August 2018 - 7:57 pm

I’m new to this hobby, and i’ve just bought a Taranis qx7, but the throttle stick doesn’t give throttle before its in 50% travel (in the middle).. Do you know how to change that?

Best regards Martin.

Oscar 11th August 2018 - 4:33 pm

Doesn’t sound like a straight forward question, please join our forum for further troubleshooting. (http://intoFPV.com)

James Wallo 20th March 2018 - 2:22 pm

Hello…I would like to know if transmitter DUEL RATE is the same thing as FC RC RATE? Should I have both my DUEL RATE in my transmitter and RC RATE in my betaflight set at 100? Thanks. Jim

Sarcoise 25th April 2018 - 5:36 am

@James Wallo

As he stated in the article, you should NOT use any rates or expo settings on your TX, let the flight controller read your actual stick inputs and set all expo/rates using the configurator. TX expo settings were necessary when using servos and control surfaces as with a fixed wing or heli – but are not needed with the use of a FC that allows you to program them internally. The FC’s gyros are able to detect the rate at which the model is rolling or flipping in degrees per second and uses the rate/expo settings to provide a consistent roll rate.

Besides, it would be difficult to set a desired rate if both the FC and TX were performing expo calculations. Ideally you would have rate/expo numbers that you are comfortable with and you’d be able to punch in those numbers on any new build as a starting point. That way, you would have a set rotational rate and you would be used to flipping 360 degrees in x time, allowing you to “feel” when a roll or flip is complete and not have to use visual confirmation.

Dan Ivanov 17th May 2022 - 10:07 am

But why not free up that memory from the FC if the TX can handle it instead?

Then you can also adjust graphs on the fly.

supernull 15th March 2017 - 8:05 pm

Now it’s march of 2017 and some things seem to be different. Like when you write “I personally use no expo or just a little expo (<10)", the throttle expo now goes from 0 to 1, so <10 would be <0.1 today, right? Also when you write about throttle mid, "You need to use this with some throttle expo, otherwise it won’t do anything." is this statement still true today? So if I want to make use of throttle mid, I have to set expo to something like 0.05? Thanks!

Oscar 24th March 2017 - 12:16 am

Yes you are right, these firmware keep changing stuff it’s impossible to keep track of and update all the articles :D
But I will try when I have time! thank you for the comment!

Michael 15th February 2018 - 10:56 pm

You cover the broad strokes which is the important part. People can get educated on the specifics with tutorials.

Your site is my favourite for technical FPV knowledge. Particularly your articles on noise filtering.

Dave 13th February 2017 - 8:04 pm

Hey man, I’ve recently taken an interest in flying quadcopters, I got a JJRC1000A to start off with and just learning how to get the damn thing to hover was a nightmare, it took me several weeks of playing around with it before I could fly it around my livingroom comfortably without constantly banging off walls and doors!!

Then I went out and bought the Syma X5C which I find a whole lot easier to fly, I’m able to cruise around outdoors with the Syma no problem at all.

But now I wanted to move onto something a bit bigger and better, also my dad has the Phantom 4 Pro which I’ve had the chance to fly it several times and it was an amazing experience, however, one thing that has me scratching my head with the Phantom, I thought with these high end drones like the DJI ones that the right stick that controls the left and right roll would always remain left and right regardless of the drones orientation, so you could just look at your display that’s connected to your controller and you’d be using that to know the drones orientation, I always thought this was how it’d be for flying FPV, or am I completely missing something?

I’ve searched all over the net to try and find an answer to this but I can’t seem to find anything at all, so I am hoping you could enlighten me here.

I mean surely people who fly in FPV through buildings around trees etc aren’t having to be thinking when and where those controls will be reversed, I figured you could use the display on the P4 controller for FPV instead of goggles??

Hope you get back to me, thanks in advance.

Chris 26th March 2017 - 11:03 am

If I understand you right, you’re saying the phantom’s orientation with regards to the pilot is what controls what direction the pitch, roll controls move the quad? If so, this is called headless mode. Usually it’s only used for line-of-sight flying, because as you said, it makes fpv confusing. I’ve flown a Phantom 3 pro (iirc), and it didn’t do this, I suspect it is a setting that could be turned on or off somewhere in the labyrinth of the dji app. Don’t ask me how though, I don’t have a clue how those things work :)

Brian 2nd May 2018 - 7:09 pm

It’s called headless mode. where no matter the orientation of the drone it will always move back if you move the stick in that direction. It is a setting.

joe 29th January 2017 - 2:41 am

Hey thanks for the help, i have a question though. i changed my rates. but i cant figure out how to get my “roll” to move only the quad right or left without adding in pitch. Right now as it stands my roll and pitch move simultaneously causing a front ward tilt when trying to “roll right”. is there a way to tune the quad so roll and pitch dont work together at the same time?

Oscar 4th February 2017 - 10:47 am

no they shouldn’t move the same time if you are only controlling pitch or roll :D
are you taking into account your camera tilt angle? with the tilt the quad will feel like it’s pitching and rolling the same time when you are doing a roll…

James 30th December 2016 - 8:46 am

Yes im using the open source cx20 and i have an issue with the battery getting drained real quick like few seconds on giving it throttle. Just need to know what i can do to make it quit draining the battery and its fully charged.

David 10th September 2016 - 12:10 am

Great article! Thanks for the help!

Robin 25th April 2016 - 10:33 am

I am new to rate mode and have 3 modes setup (selected using a 3 way switch on the TX)
Angle and horizon “feel” fine but when I go into acro I do feel it needs a little expo
-possibly a mixture of me being new to flying acro and deadband being set at 6 because of jitter…mainly me being a ‘newbie’ thing though :)
I can fly helis so am kind of surprised I’m struggling a little- but my 250 quad seems more reactive/skittish than my Trex250 heli!

I have added some expo on the TX for AIL and ELE (15%) , but only when acro is selected and it does seem to be helping massively and I could possibly afford to lower it slightly – I can’t see how to only apply expo on the ‘acro’ mode in Cleanflight and leave angle and horizon without, so I guess I’m going to go with this method for now and slowly reduce till I have the skill speed and accuracy of BanniUK..(In my dreams!)
Weaning myself off horizon is the goal :D

Oscar 28th April 2016 - 12:05 pm

Only way i can see is to have separate profile for different modes… but really you should get used to rate mode and completely forget about self-level mode :) All top pilots only fly rate mode.

DeeHawk 14th June 2016 - 9:01 am

I’ll challenge anyone who thinks they can LOS better through a proximity track without gyro. :D
It’s horrible for FPV tho :)
Nice compilation of tuning tips yet again!

Spencer 15th March 2016 - 11:54 pm

Hey Oscar,

You have helped me countless times in the past, but in this case your post was detrimental.

mmix is now zero based instead of 1 based. If you define motor mixes starting from 1 it will not acknowledge them until you specify a motor 0 mmix. This can be very confusing based on your tutorial. Also: these settings are very helpful to know:

mixer custom
mmix reset

And finally, this website helped me figure out the issue I was having… so credit due: iforce2d.net/mixercalc/


Oscar 16th March 2016 - 1:04 am

are you commenting on the right post? I don’t think I talked about mixer in this article?
I am assuming you are referring to the “custom motor mixer” post… that was written back in early 2015… cleanflight decided to keep changing things around (including the name of the function), being a part time blogger, i tried my best to amend it and keep it up to day… but there are times I just can’t keep up with things… so if there was any confusion caused I apologise.

I would also really appreciate it if you could point out which part of the article isn’t correct or clear… I don’t use mmix for a very long time and I start to forget about some of the details. (and that’s why I like to document/blog things)

Newbie 23rd February 2016 - 6:24 pm

Hi Oscar !

I dont speak well english and i am new with cf and naze32.
Your explanation of these are very easy to understand than cf docs.


Mike 13th December 2015 - 10:56 pm

Hi Oscar
New to quads. Just built 280 with scorpion motors, BL Heli 20 amp esc, Naze 32 ver6, dx8 tx, Orange 615x using ppm and Clean Flight set up. On throttle up the quad noses over. I rechecked setup and same results. In motors tab in cleanflight the motors do not come up even when using transmitter but come up even with master motor tab.
Where do I start looking for problem.

Todd Brown 5th August 2016 - 2:28 am

Start with the simple things. Have you done a throttle calibration?

Paul 19th September 2015 - 7:32 pm

Hi Oscar,
Are your certain that throttle mid has an effect if the expo is off?

My mini quad is 7:1 power to weight and I have the crash on landing problem :) I tried throttle mid at both 20% and 80% and it didn’t seem to have any effect at all. I’m using luxfloat…

Oscar 21st September 2015 - 3:00 pm

sorry yes, i should have mentioned throttle mid is only effective when you give it a bit of throttle expo :)

Antonio 15th September 2015 - 3:22 pm

Congratulations for the excellent tutorials and articles técnicos.Qual would be quieter fee for “exponential” more suitable for one who never flew and will learn for the first time.

Daz 15th September 2015 - 2:01 pm

Exactly what I needed to read to fix my flight problems from last weekend. Thanks.

Ondrej 15th September 2015 - 9:26 am

Hi Oscar,
I was playing with the Y/P/R rate lately. I was looking for the meaning of the numbers and still was not able to figure it out. In the CF forum, i found repeatedly, that the Y/P/R rate is multiplier. Well, i doubt that, because the default value is 0, as far as i can remember. Do you know, how these rates are processed in the PIDs?

Oscar 16th September 2015 - 4:01 pm

Hi Ondrej, like i mentioned in the post, it depends on PID controllers, these rates don’t necessary affect PID.
for PID C 1 and 2, they only affect your stick sensitivity, saying they are multipliers so it’s easier to understand for people, it’s not like you really multiply the stick values with the Rate Number… no! :)
Not sure what you are trying to do… just turn it up or down to where you see fit :) for normal users like myself… i see there is no need to dig deeper than that unless you are a developer, or you have having massive problems with it…

Holger 14th September 2015 - 9:14 pm

I always tought it’s recommended to set Expo in the Tx and not the FC? Most pro pilots don’t seem to touch the Expo settings in Cleanflight at all.

Oscar 16th September 2015 - 3:34 pm

HI Holger, everyone has their own way of doing things, end result is similar anyway wherever you are setting it…

Holger 16th September 2015 - 8:43 pm

I was curious about this topic and got an detailed explanation from joshuabardwell on why to prefer FC expo over Tx expo: rcgroups.com/forums/showpost.php?p=32705942&postcount=999

Oscar 21st September 2015 - 12:40 pm

that’s a good theory and sounds legit to me :) thanks for sharing!
