PID Tuning Masterclass - Part 4 - Optimizing I Gain

Let's take a look at what low and high PIDs do. This will give you a perspective on what to change when your copter is not behaving the way you want it to behave.
In this video, I show you low and high I gain. We also cover how P gain and I gain interact with each other.

This playlist will culminate with my 1.5 hour PID Tuning Masterclass presentation at the NYC Drone Film Festival on March 18, 2017. (Note: the presentation will be March 18. The video will be uploaded some time later.) In the mean time,
The copter is running Betaflight 3.1.5. The copter is the AllcarbonRC Coyote. goo.gl/Fe7dtQ

[@UnlimitedVertical]

I'd like to see this entire series re-done with Betaflight 4.0

[@GiffysChannel]

THIS

[@glossjunkies6026]

AGREED

[@adventureohio2]

Please Daddy?

[@chrisstolle5664]

Agree

[@Pile_of_carbon]

This series helped me tons! One of my quads (pre-build one) acted up after a motor swap and this series helped me get that under control. I did indeed learn something today.

[@zaniix11]

OMG the way these videos ends its like NOOOOOOOOOOOO, I want more, you were just talking and boom it ends.

[@markrankin3094]

Brilliant vids. I've not been flying much from last summer and was only learning the pids so these new vids are the best refresher in pids. Thank you Joshua!!

[@MadMarcWinnipeg]

Man, I appreciate the lessons Joshua. I'm doing my very first tune on my very first programmable flight controller and I couldn't have started without ya. Thanx brotha 😊

[@StacemanFPV]

Loving these vids! I can't wait for some warmer temps again so I can go do a nice tuning session.

[@jamfpv2758]

One of the best PID Tuning Guides! Thanks Joshua!

[@chucksmith41]

Nice work here Josh. PIDs are much less a mystery. Very helpful to me anyway.

[@JoshuaBardwell]

+Charles Smith glad to hear it.

[@michaelwilkes0]

if you hate hearing, "battery critical" all the time, you can add a diode and 250uf capacitor to the voltage sense wire to slow down the voltage change. (though it makes it read 0.7v lower than it really is.) Or, if you have a taranis, there is a cool trick someone did with a delay parameter in the mixer to delay the battery alarm.

[@JoshuaBardwell]

I've set up some logic like that in the Taranis.

[@michaelwilkes0]

Awesome. I fly spektrum and that is one feature I really wish spektrum could do. I always have to add a diode and cap and then always remember to set my voltage alarm 0.7v lower.

[@costantinoiurino6343]

maybe you can elaborate the betaflight anti-gravity parameters on that occasion josh ?great series !!

[@JoshuaBardwell]

+Costantino Iurino soon.

[@3000gtwelder]

That is so cool you can adjust your pids in flight. Makes me want to switch from KISS sometimes lol. Great videos.

[@dizzyfpv4903]

3000gtwelder A feature coming very soon for Flyduino

[@Mupshot]

rewatching because INAV7 is giving me fits.

[@Ensetsu981]

Thank you Joshua, very helpful video Love the end again :D

[@t-producciones5138]

Such a great video! Awesome explanations. Joshua, do you have any written text on PIDs & Rates you can share. Would really like to study this in a way I can perfectly manage all PID and rate concepts. Besides of course replicating what you show here to get a better feel of what I have learned. Thank you very much for all you do and share.

[@thomase5943]

I think the uneven throttle response is caused by ESC tolerances.

[@pnachtwey]

You are guessing. Yes, there is a relationship between all the gains.. Think on the quad as having inertia around all 3 axes. The motor supply force. Multiply the force by the dist from the axis of rotation to get torque. Then divide by the inertia to get angular acceleration. That is simply 2 poles at the origin in the s-plane. After adding the paid the will be 3 closed loop poles if you ignore the time it takes the props to spin up. Now place the closed loop poles and calculate the paid gains. But first the units need to be known.

[@JoshuaBardwell]

You're so smart, stop commenting and show me how good your quad flies.

[@pnachtwey]

Study this dspace.ucuenca.edu.ec/bitstream/123456789/21401/1/IEE_17_Romero%20et%20al.pdf See equation 18. This document talks about placing poles and zeros but doesn't show how to do it. I may make a video on doing that. Marlon Clark asks below "Why aren't flight controllers able to tune themselves?" That is a good question. The trick is getting the values for equation 18. Then it is easy.

[@DashzRight]

I would have loved to see what high I gain do.

[@JoshuaBardwell]

It makes a "stiff" feeling. Once upon a time I got I gain high enough to oscillate, but it's sort of unpredictable whether it will do it or not.

[@Conarc-313]

I follow your videos almost religiously. Informative, up-to-date, and easy to follow. Has helped me so much with building my 1st 2 drones and getting them tuned in (mostly). I do have a question for you tho, if you see this, and I was wondering if an imbalanced motor would cause mid-range oscillations but not on low or high end? I have been trying to tune it out for a while now, and while better, its still there. If I had a spare motor of the same type id try and replace it but I dont (stock issues). I have tried other things such as different props, re calibrating the FC, and others and its always very similar. I was just curious on your opinion? I know there are other variables, some ive tried, but dont want a massive page of text here listing em all. (I will be buying more motors ne ways so im not trying to skimp out, just looking for a pros opinion and possibly solutions?) THANK YOU!

[@JoshuaBardwell]

Yes, it's possible that you get some resonance at a certain throttle position.

[@johnhadden9735]

Conarc เฟ็ด

[@MrBirdshell666]

things were difficult without dynamic notch and feed forward.

[@LachlanPeknice]

Super helpful, once again! Thanks!

[@Flyznflyz]

How are you adjusting the values in flight,with a switch...do you have a vid showing how to set it up to make the adj in flight?

[@JoshuaBardwell]

+Cool Digs search my channel for "in flight adjustments".

[@sk8rix24]

HI Joshua, Will there be more? Your helping me a lot here.:) Great job!

[@JoshuaBardwell]

+Michael Ramirez there is at least one more.

[@sk8rix24]

Joshua Bardwell ah awesome.. I did some tuning today but it was okay as it was my first time. Kiss fc is hard to tune as it's already smooth flying

[@ntycefpv8533]

I'm having this exact punch out to no throttle wobble "issue". Looking forward to tuning it out. Thanks for all the help so far!

[@damonbfpv]

watching this to try figure out my triblade problem,flew fine on 2 blades now im on triblades it drifts all over the place when im hovering lol

[@kenaidiaz8009]

Should I put on slightly damaged props or brand new ones when I tune my quad?

[@ichoozjc]

Nice Video. Have you played around with the newish "anti-gravity" feature? I think it's supposed to help with that punchout dip.

[@JoshuaBardwell]

+Chris E wait for it...

[@ichoozjc]

Joshua Bardwell Lol. I posted just before the last 5 seconds of this video. Had a feeling... Can't wait to see what results u get. I'm exactly where you are, always have that little dip in punchout.

[@brycepatrick3466]

Chris E same here!!!

[@RichardRaueiser]

I am sticking on this, now; cause I am trying to set it as crusty like prebacked can taste fresh, dealing with an Align MR25x FC, handling 1600Kv motors on 4s spinning 6" props!?! silly yaw jitters I encounter, for instance aka. Thank's digging so deap in the topic.

[@Shauny_D]

How does this change for different setups? For instance my brushled setups are unflyable until I get up over 100s on everything. What about 5” vs 3” vs whoop? Ducted props? In vs out setups? How do these thing change and react differently

[@roscofpv2357]

Josh, is it possible your COG was back a little bit on this quad and that's why punch outs raised the nose? If the COG is off it's going to cause this issue. Your back motors are working hard to help the back keep up with the front motors. I had this same problem recently.

[@JoshuaBardwell]

+RoscoFPV no, it's not the CG. It's 100% an aerodynamic effect.

[@FerralVideo]

That's weird watching the quad "lock on" when you step on it, then "wander off" when you let off, when demonstrating "too low" I-gain. It's almost like you don't even have Air Mode on, and it's just free floating at zero. (I'm still learning to fly and don't often use Air mode)

[@TheDarkWolf18000]

Thanks for this great playlist. I have the same problem qs you have on high throttle chamges. Is there any eay now to fix it ? At the end of video, it just cuts off dirty, but there is no more explanations or tests, and im trying to get rid of this effect of high throttle chamges

[@Cc-nj2zm]

What would happen if you tried to turn sharp going fast like a tight u turn but with low I gain? Like going fast on a straight away, but then making a sharp U turn with low I gain?

[@MrAlvits]

sir me i know where to apply this sitting in radio or in betafight Im used 4.2

[@MrAlvits]

sir I will take this PID tuning sitting in my tango 2 ? how

[@marlon82mc]

I am still new to the hobby myself, but besides price of these things, I feel like tuning is a big obstacle that hinders newbies. Why aren't flight controllers able to tune themselves?!

[@frinky]

Marlon Clark Watch these videos and you'll be set

[@nitro2037]

youll be fine....most RTFs will fly right out of the box..you wont even want to tune till u remember u can do these things............"tune themselves"?..lol you sound like they have heart beats and can read minds and know exactly how and why you fly...lol...maybe someday.....lol...but for now i like the separation and the hobby of it....

[@pauliman1098]

I think he's saying to add more than 2mbs of dataflash and give them a sort of genetic coding algorithm so they can tailor their pids for thhemselves/the pilots style. I think that'll be the next big thing

[@TheChoFace]

Neat idea! Self analysis of blackbox data for efficiency’s sake seems a likely creation of the future. Probably already being developed! Rates are still something you need to set, though.

[@bears7777777]

some do tune themselves. It's called autotune. just gets you in the ballpark but if you want it perfect you would have to dial it in manually

[@sharpeye32]

How do you tune the PIDs on the go?

[@jamesnotarianni9190]

How are you adjusting I gain and flying at the same time? What witchcraft is this!?

[@smcclure3545]

Thanks again for the vids Joshua, will you be talking about TPA?

[@JoshuaBardwell]

kzbin.info/www/bejne/pqXLgZaObNipjbM

[@Gruuvin1]

It looks like pitch stick up is pitching the quad back and pitch stick down is pitching the quad forward. Are my eyes playing tricks on me, or do you fly with pitch reversed from most normal setups. Seems opposite from airplane and heli setup.

[@JoshuaBardwell]

Pitch stick up pitches forward and pitch stick down pitches back. I'm flying with normal settings on the sticks.

[@jonathane8585]

Great tutorial series but, after watching the first 4 parts of this series and then going back to your RaceFlightOne video. I think RaceFlightOne is the way to go from here.

[@JoshuaBardwell]

I mean, make whatever decision you want, but this isn't a tuning series, it's educational. So I don't think this is a good way to judge the flight performance. I'm intentionally doing bad things with the PIDs.

[@jonathane8585]

I understand what you are doing and the intentions of this video. I am basing my decision of what I have seen from RF1 with Stock PIDS, and comparing that to not only this series, but all of your TUNING series videos. I have seen them all and I have learned so much. But the stuggles you experienced to make your quads fly as nice as RF1's stock PIDS is what is swaying me to favor RF1 now. You mentioned in your RF1 video that you will do tuning videos for both BF and RF1, and I am hoping a comparison. I will await your BF tuning and RF1 tuning videos to make my final decision.

[@Skruteas]

Betaflight stock PIDs have flown great on my 5, 6 and 7in builds. I have to force myself to tune them they are so good.

[@logo8009]

Joshua, I having a slight issue with a tune on a flip well more of a power loop I would yaw to the right a little. It fly's well other than that with a few oscillation here and there but not that bad. I have watched this series looking for a little help. Any suggestions on where to start first. Thanks You really helped me get and many others that have struggled from time to time.

[@JoshuaBardwell]

+Logo 800 if your yaw P is at defaults try raising it.

[@logo8009]

It's not but only like 5 higher. I will give it a try. Thanks

[@DangerDavefpv]

no offense im hoping but do you where a sarong wasnt sure?

[@JoshuaBardwell]

+David Downs yes.

[@DangerDavefpv]

Joshua Bardwell I am sorry for asking this I just seen u did video of this and I didn't mean to cause any disrespect, I respect u and ur knowledge alot and I'm very happy that u help us fpv guys.. ur awesome guy. just wanted to apologise for asking.

[@sxdev]

What is your tip for an x frame with underslung battery, when catching it from a dive with low throttle there is a real pendulum effect sometimes, just fly around it or raise I drastically? I don´t like the feel of high I so I prefer just avoiding it, any advice ? This series was awesome btw great work

[@JoshuaBardwell]

+Chris S. Anti gravity gain I guess.

[@patrickcol]

This is a fascinating series Joshua but it seems to my uninformed mind that the entire process of finding the perfect tune could be automated through smart software. I know there used to be an autotune, could it not be refined?

[@JoshuaBardwell]

+patrickcol this is one of those things that is easy to conceptualize but very hard to implement.

[@sxdev]

It´s already implemented with autotune but I havn´t heard much about people actually using it, the results are not impressive

[@badmofo350]

I want to use the buzzer on a matek 5in1 and trigger it from a switch. The matek manual tells me the pwm signal it looks for but I'm not sure where the signal wire would come from on my lux v2. There are buzzer pads but that only puts out voltage not a signal. The lux only has 4 motor outputs so I'm not sure how I would do it. Any advice is appreciated.

[@JoshuaBardwell]

+DrFuNK you need to use channel_forwarding but I'm not sure the Lux breaks out the pads the aux channels would be forwarded to. Maybe you could use Betaflight resource remapping to move the signal to an available pin. The bottom line is I don't think it will be easy for most people to get it working.

[@badmofo350]

Joshua Bardwell ok thanks. I'll just go buzzerless. One more question: the 12v linear bec on the matek says up to 500ma continuous and 1a for 10sec/min. I want to run the Unify pro Hv off of it because it's filtered power. Unify manual says it draws 600ma at the 800mw setting. I personally think it would be fine but also I'd hate not being able to fully trust it. I'm not using the 5v/.5a reg built into the Unify for the cam but tbs doesn't say if the ratings are with or without the reg in use. What would you do if you wanted to run 800mw? Use a different pdb/reg?

[@jackhammell1926]

Down the rabbit hole

[@michaelwilkes0]

@Joshua Bardwell What was the result? Did you ever get rid of the nose drift after punchout? After an hour of tuning I got all my P and I terms up to 100 and it still wont go away. I have almost no oscillations though. (250 quad, spracingf3evo).

[@schumata3356]

Great one

[@playlet]

Please make a video on setting up filters. Now there are 2 filters and I can't find info on how to set it up...

[@JoshuaBardwell]

kzbin.info/www/bejne/n4akhKuPm5Jpqck

[@playlet]

So I only need to set my max noise value to d-term notch frequency? I'm confused because i found a tutorial online where they set it to gyro notch frequency. Plus, then there was only 1 filter.

[@rtron2012]

i think it thend to nose up down 'cause the quad is not balanced from center of the propellers may be bad battery postion ....

[@spiderman-lf7wm]

how about ESC's ampere?

[@MaxBeamer]

What are some symptoms of too high I gain? Can micro wobbles on yaw at low throttle be one?

[@JoshuaBardwell]

No I don't think so. Honestly I think you can crank I pretty high on the latest firmwares and not get anything radically wrong, just a bad flight feel. Very stiff. Micro wobbles on yaw are probably either high yaw P gain or too much noise/not enough filtering. Soft mount the FC. Maybe lower gyro cutoff filters.

[@ADAMKINGTV]

Hello, This is a really helpfull video thanks.its getting me through tuning my matek/chameleon build. struggling at bit to lose jello. I have a question, when starting a tune should the filters in Betaflight be set on or off? thank you

[@JoshuaBardwell]

I usually go to PT1 for sure and then remove the gyro notches one by one, looking for hot motors as I go. Then I tune. Then while adjusting D gain I see if I can remove the D term notch without getting hot motors.

[@ADAMKINGTV]

ok ill give it a go , thanks for the answer

[@TomMinnick]

My apologies if it's been covered previously, working through your back catalog now. But what I am experiencing is when I yaw the copter seems to roll. Example: I take it up to level flight in a hover and give right yaw input. The copter yaws right will simultaneously rolling right (no roll input given), as much as 30degrees or so on a 90+ degree yaw. What is your opinion on what that could be?

[@kentboehm1981]

Do you have any camera tilt?

[@JoshuaBardwell]

+damage.cc the copter rolls the same direction as the yaw, or the opposite direction?

[@kentboehm1981]

Sorry Josh was referring to damage.cc when I asked about camera tilt. I know you have it!

[@TomMinnick]

Rolls the same direction as yaw. I.E. if I yaw right, it rolls right. I don't currently run a HD camera. I'll try to get some GS video of it. Also, I do run camera tilt, about 30 degrees or so, but I wouldn't think that would be a factor in this.

[@kentboehm1981]

damage.cc no if its in the same direction, it's not the camera tilt. what version of betaflight are you running? any chance you can get a blackbox log? that would be the easiest way to help you out. I'd be happy to take a look at your log. I know Josh is pretty busy these days.

[@norbertwenkel9139]

Joshua Bardwell, when doing your PID lessons, which i like a lot, is AIRMODE on permanently? Thanks for your answer

[@JoshuaBardwell]

+Norbert Wenkel yes.

[@bradsimionescu]

Dear Joshua, do you think that a custom mmix that takes into consideration the exact geometry of a frame will help/improve in any way the flight characteristics of a quad? Thank you very much for such good content!

[@JoshuaBardwell]

Not if it is a flat quad (i.e. not an A-tail or V-tail) with rectangular or square motor layout.

[@bradsimionescu]

So basically this geometry information does not help the PID algorithm on roll and pitch in such a way to be more correlated to the actual frame geometry ( i am refering to a 210 qav). I was thinking that by putting the correct mmix information one will get closer ( equal ) PIDs on roll and pitch or something like that. Thank you again for making the time to answer our questions!

[@JoshuaBardwell]

+Brad Simionescu yes, PIDs would be closer to equal. But the dominant factor is not motor layout but weight distribution. And determining that is not trivial for most people.

[@bradsimionescu]

That is insightful Joshua, thank's again!

[@jeremyred6343]

Hi, in just hovering, when i throttle up or down my yaw drifts slowly to the right. Until i throttle some more it rotates the quad like more or less 90°. Is that a sign of low yaw I gain? No matter how many times i add yaw trim it doesn't go. And also my roll, it drifts left even no wind and just keep adding trim till its almost 50% trim. Are those i gain probs?

[@JoshuaBardwell]

First, don't add yaw trim :-) Your channels should always center at 1500 us or the quad will have issues. Go into the Receiver tab and use subtrims on your transmitter (or trims if it doesn't have subtrim) to adjust the channels until they center at 1500. Then never touch the trim switches again. If the quad is in autolevel mode and is drifting, here is how to fix it kzbin.info/www/bejne/paWtf62Qp6pgr80 The quad will never perfectly hover. You will always need to make small adjustments, but it should only be small adjustments.

[@DangerDavefpv]

what would cause a almost yaw to right when doing punch and most time hitting 75% throttle? its a very quick jerk to right and back ?

[@JoshuaBardwell]

raise yaw P gain by 25% if you are at default, then raise yaw I gain.

[@DangerDavefpv]

Thanks ill try that, well lol i had anouther random loss of data on board today but was the 15th flight this time and i was giving it second chance but nope again it erases all setting.. when board plugged in after happen saids something like "unrecoverable serial port connection" but the revo f4 board has no memory for blackbox so not sure whats happened. Omnibus f4 pro v3 will be going on soon though.

[@DangerDavefpv]

Joshua Bardwell so I have magnets coming loose again lol don't know what or why they do, so I used c.a glue to fix one then I had anouther come out 8flights after. I use mb2207/2400kv there strong but these had magnet come loose and emax 2205 did it to any suggestions? motor on hard run 80deg

[@vegardkt]

Question: Are there any form of autolevel here, or do the control system only control the rotational velocity?

[@JoshuaBardwell]

Acro mode. No autolevel. Gyro-based only. Rotational rate (degrees per second).

[@ishootyou805]

Hi josh, When i give full throttle my quad begins to whooble. When i put a heavier batterie on my quad the problem is solved... what do you think?

[@kostasganosis8019]

hello joshua one question: if I do roll ant the quad overkorekting I have to decrease the I gain?? or encrease?? Sorry for bad English.. thank you

[@JoshuaBardwell]

+Kostas Ganosis I don't think I gain is where I would start. P and D.

[@DangerDavefpv]

what would be common issue for quad to yaw left right after punch out?

[@JoshuaBardwell]

Raise anti gravity gain. Make sure anti gravity feature is enabled in the Configuration tab.

[@DangerDavefpv]

question im running 3.1.6 so would it be better i go ahead and update to 3.2?

[@alexdalton7290]

Hey josh I'm having trouble with my fpv system I keep frying Cameras I am getting 16v to my camera leads and the camera says it should be good from 5 to 17 volts am I just pushing it to close should I try a camera with a max of 22v like the run cams blew up 2 foxteer cameras please help thanks

[@DroneMesh]

Alex Dalton Use a bec with low esr cap

[@Conarc-313]

What camera are you using? Ive had very positive experiences with the foxeer hs1177 and foxeer arrow (hs1190?) Ive only run vcc 3s to the hs1177, but for the Arrow ive also hooked up vcc direct off a 4s w no issues (has a cheap OSD fer flight time and volts so requires direct bat connect, been running this for about 3 months) If you do go for the arrow tho, the 1 problem ive had was while changing the camera case, sometimes the camera doesn't sit perfectly square inside the case causing corner blurs, easily solved w a dab of hot glue. Good luck m8!

[@JoshuaBardwell]

I wouldn't run a 17v camera off of 4S vBat. I would use a 12v regulator.

[@alexdalton7290]

Joshua Bardwell ok thanks Could I use a linear regulator?

[@alexdalton7290]

Conarc thanks I believe it was 2 foxteer mini fpv cams 700tvl ( was weird cus I plugged up once and it was fine plugged up agian and magic smoke I'm trying a run cam swift now with a 12v regulator to bring the 16v down to 12v

[@Tavdog]

I've having nose dip after punch out problem and no amount of I gain can fix it. Have you discovered any other cause of this problem ? It seems like it's caused by motors spinning up and braking at different rates or something. I could see an aerodynamic effect causing it too but what could it be ?

[@JoshuaBardwell]

Use anti_gravity_gain. Enable the Feature in the Configuration tab, then raise the gain number int he PID Tuning tab. Start at gain of 3 and go up from there. Usually between 3-5 sovles it on my quads.

[@Tavdog]

Worked like a charm ! thanks.

[@TheKitorama]

Hi Joshua maybe you can help me. I only have oszilations on my quad when I do high throttle punches. I tried that tpa but it does not seem to have an effect. Have that on 2 same builds. Maybe you have a tip for me.

[@JoshuaBardwell]

Reduce P gain.

[@TheKitorama]

Thank you that helped me for one copter. On the second it didn´t. I have seen that i forgot a cap on this. After soldering it this copter seems to fly right. Can a cap influence the high output (35A ESC)? Thought it´s just for Videoprobs...

[@rohansinghkunwar4740]

my quad move back how to fix it

[@kadebulow887]

When I punch out then cut throttle, my quad acts as if it had no thrust keeping it level, it just starts tumbling to the ground, I raised my min throttle from 1070 to 1080, did nothing.

[@JoshuaBardwell]

Turn on air mode.

[@kadebulow887]

Joshua Bardwell thanks Joshua!

[@TaterMater22]

Are you flying in acro mode in these videos? I am currently trying to switch to acro, so I watch as many videos with stick overlays as possible to try to get a feel for what the sticks should be doing. In your videos, if you turn right, for instance, it doesn't appear that you have to take the stick back to the left side of center to stop turning? It is difficult to see when it is happening so quickly, though. I am just really struggling converting to acro mode.Especially on indoor tracks on the simulators. Any tips?

[@JoshuaBardwell]

+Taylor May in acro, the copter stops moving when you center the stick.

[@redazu911]

Is there a part 5? It seems you ended this one and never quite ironed out the wobble on punch. You ended the other two around like 70p 50d or something but ended this with them lower. I assumed once you found the sweet spot with P and D, then you just raise your I until it holds solid attitude?

[@JoshuaBardwell]

These days you should use anti gravity gain instead of raising I to keep the nose stead on throttle punch. There isn't a part 5.

[@redazu911]

Ohhhh alright thanks!

[@SnowbirdSteeze]

Joshua Bardwell as in, turn it on or did you mean increase anti gravity gain?

[@rotorixfpv]

How do you adjust pids in flight?

[@JoshuaBardwell]

kzbin.info/www/bejne/gKHRdICCot2gm5I

[@rotorixfpv]

Joshua Bardwell oh that's not really what I mean. I know about this adjustments. I'm talking about OSD with PIDS in flight. But in comments to that video I saw something about github and betafligh osd.

[@JoshuaBardwell]

Betaflight OSD has the ability to show PIDs on screen in real time.

[@DennisSantos]

How do you adjust the PIDS whilst flying?

[@JoshuaBardwell]

kzbin.info/www/bejne/gKHRdICCot2gm5I

[@MBSTimberwolf]

Out of curiosity, how many times have the birdhouse or pole been struck?

[@JoshuaBardwell]

Not yet.

[@MBSTimberwolf]

Bravo! If it were me, I'm afraid my quad would make it target number one.

[@kn8alpha263]

Oh man.. you are just lucky to have a flying field out your door, all the time in the world to PID tune and then you go about adjusting PIDs while flying,, makes my blood boil =D :'(

[@nyx574]

Joshua, how are you editing the PIDs while in-flight without the quad reacting the the stick movement?

[@JoshuaBardwell]

+NyxFPV kzbin.info/www/bejne/gKHRdICCot2gm5I

[@nyx574]

Thanks!

[@JT-jy2sy]

Joshua, on a windy my quad wobbles when I was just flying in straight path. I had to lower the I gain and wobble stopped. Is this correct?

[@JoshuaBardwell]

+Jack Truong well it worked for you.

[@colelandreneau304]

how many packs does it take on average to tune a quad

[@JoshuaBardwell]

It really depends on the quad. Some quads fly great on default pids and only need a little tweaking. Some quads, you're constantly trying to get it right.

[@colelandreneau304]

I only have 6 packs so I'll see how that goes. Thanks for the help

[@christianhoxworth8049]

THANK YOU FOR THESE VIDS! #ProblemSolved

[@GiffysChannel]

This is like trying to understand color in 3D

[@janprejzek4706]

This tuning series ended in nowhere ? Looks like there is problem to tune betaflight properly right ?

Hi Joshua, you say that with I term, the quad stay on its attitude after punch throttle. but does the CG influence ? my motors spins when the throttle is 0, and tends to horizontalizing the quad. So do I need to stop the motor when tuning PID ? thx
