IMPORTANT TIP I MISSED: --> Turn off Air Mode when in Angle Mode!! It helps a ton for not "sticking to the wall" and for general recovery after hitting things.

[@marinehm]

hahaha. Who's flying around in angle mode.

[@uavtech]

@@marinehm , people racing around in the house. It is much better and faster. PID controller reacts for you when you brush against things much faster than you can.

[@ProjectMockingbird]

that's one of the things I really like about Silverware, it has special code in it's angle_pids section to recognize these events to not do the wall suck. As you all know I've been a big proponent of no air mode in Angle for a while now, and I still generally feel that way other than I really like how Absolute control feels and it can only work with Air Mode on.

[@ProjectMockingbird]

@@marinehm I would say 90% of people race Whoops in Angle mode including all of us (JET, Vanover, Nurk, Gab707, Phluxy, Nubb, JesseP, Noodle to name a few) that flew at the Tiny Whoop Invitational. :)

[@nathana5379]

Man thank you so much for posting this. I just got my Mobula7 V2 (came with Crazybee F4 Pro V2.0 Flight controller) and I made the mistake of flashing to Betaflight 4.1.6 before even flying it and found myself in a heavy jam when I went to fly it. The oscillations were soo bad on takeoff it wasn't even flyable. I tried other people's PIDs with little to no luck. I thought the problem might be because I was copying everyone's PIDs from their F3 flight controllers, but apparently that's not the case. I ran your PIDS and the thing is night and day Butter compared to everything else, so thank you so much for this!

[@pkvillager]

Thank you for this video. Got my Toothpick running nicely tuning just through goggles since my FC doesn't have BB. Normally I tune my 5" rigs just by tweaking defaults and maintaining the P/D ratio. But that had my P too high and I was getting close to runaways. Finally reset to defaults and went step by step through this vid and it was a much better process and having D higher than P was my silver bullet. I would really like to see logs since I cant see how I is doing so I just set it to 35 lol... I'll do the JB method of upping I until things get worse then back off a step or two. Looking forward to your Toothpick tuning video for comparison. I'm basically running Kabab's setup on 2S at about 85g AUW.

[@fprintf]

I used this exact tuning on my Mobula7 on 1S and it is perfect in 1S acro and horizon mode. Thank you for doing all the research and work... next up, 48khz and maybe JESC too!

[@drbra1n]

JESC 48KHz works especially good with HappyModel's crappy LiPos, it is free and you should try it out :)

[@fprintf]

@@drbra1n Thank you for the recommendation. I just flashed to 48khz mode and it seems to be fine. I'm not seeing any longer flight times but the throttle seems smoother for some reason and the amp draw doesn't seem as high in the OSD. I'll run a bunch of batteries to be sure but at the minimum I did no damage with the update! This Mob7 flies great on 1s inside the house.

Thanks a lot for this video! It's amazing what you've achieved in terms of flight performance with a whoop. I flashed my BetaFPV Hx 100 toothpick to Betaflight 4.1 and started to work on the rpm filtering with default PIDs but it flies just like the whoop at the beginning. Can you estimate when the video for a toothpick will be online? I'm definitely looking forward to that.

Hi Mark, thanks for the all the pid tuning videos, I'm slowly starting to get my head around things. One question, how do I record blackbox files if my fc doesn't have onboard dataflash chip or sd card like the mobula 7?

[@marinehm]

Very informative !

[@ja3ntr0py]

Hey uavtech, love the videos always good stuff. Reminds me of being back in school, how much I love controls and how much I sucked at it. A quick question, and I've seen it come up time and time again tuning my quads. Looking at PIDtoolbox's step response graphs I get a good step response on moves with greater than 500 deg/s (decent rise time/single digits overshoot) while dialing in my P and D however my sub 500 deg/s step response is trash (20-30% overshoot). Any ideas?

[@uavtech]

Do a flight with full rotation moves and stepped moves (the half rate twitch moves I show in videos). Put that into PID Toolbox. See what you get. If still overshooting, look at the log directly to see if that is what you see (confirm). If overshoot, turn off FF and see if you still get it. If so, reduce P till it stops. If not, turn back on FF and use D_min as D-Boost to stop the overshoot with your desired FF gains.

[@normcleod360]

I too love to Whoop inside, but go out for insane speed runs. I have a 3S Whoop that screams in a fly-by. I can get ridiculous angles without needing full throttle, but seem to get a lot of prop wash in tight turns. Hopefully this video helps me fix that. Shout out to JB for sending me here to check you out.

[@bluelinefpv559]

Very informative video. When will the video be released on the Toothpick? Iam having some issues with tuning mine and would love to follow along.

[@upplsuckimcool16]

Hey man I ran into something interesting. I was helping someone through a forum tune his quad, however it's like a side project type thing to see if we can get a consumer grade drone to fly acro with just a hobby grade FC and ESC. The interesting thing is that we tuned it for a few days and finally got it to look slightly better in the BBlogs..... The FC is an F3 and we are at outrageous PIDs like 70 on the Dterm and 90 on Pterm lol... So He sent me a screen shot of his filter tab and I saw tht RPM filter was being used... I suggested he disable the RPM filter and when he did it was like magic... all of a sudden those PIDs WERE outrageously high and the drone flew 100x better..... Before removing the RPM filter the gyro was following the set point during a hover, but as soon as the stick was moved it became horrendously unstable.... I had thought this was just the nature of trying to do this particular project. The question I have is this..... Why would removing the RPM filter have made such a drastic improvement? Does it have to do with it being an F3 FC? I had the theory it might work removing the RPM filter, but I had no basis for this theory, and when it DID work I was like pulling out my hair trying to understand WHY. I was hoping you could had some insight as to why this might've been the case....

[@uavtech]

RPM filter doesn't work on F3 boards unless you have a special build. Soooooo...

[@MojoPapiFPV]

Would love to see some PID and Filter screenshots of UAV recommended settings for different class quads. Something much more agressive than default settings and that uses the most common setups on certain categories like freestyle 5" (600g ish) light prop, 2207ish, etc.

Hi! Great video as always. One question, I see your tuning on beta 4.2 in which u suggest to disable dmin. For the woop class with a D so high is better keep the dmin active? Thanks a lot!

[@uavtech]

For whoops you need a high Dmin gain. So weather you turn D_min for a boosted D-gain to the Dmax is up to if you need additional dampening for high FF values or not.

[@CiottiFPV]

Sooooo since none of the whoop boards have blackbox for me to tune one properly, any thoughts on how you would massage this tune for an acro only 65mm rig with 0802's? Also, any guess on I terms? I'm in the 90's now and it feels good but I'm wondering if you did some proper testing to really dial that in

[@ianozborne1555]

Can’t wait to tune my 3 inchers, also, I have an f7 dual gyro board, but I can only pull off dshot 300 with 4k 4K for my rpm filters. Does the additional gyro take up the extra processing power? Even with the accelerometer off if I wanna run 8k 8k my tasks values end up being around 7700-7800 and 70% max load. Would it maybe be better to run one gyro at 8k 8k or keep it at both on 4k 4k? Thanks!

[@wh0deany]

Great video Mark, just wondering why at the end of the video you have Dyn Notch Q set at 500, but at the start its at 250. Which do you recommend for whoop class?

[@uavtech]

With Whoop, 250 ONLY with RPM filter enabled. If RPM is off, then 120 (default). The Q = 500 was my Toothpick quad which has ultra low noise level.

[@Darksagan]

Damn you know your stuff.

[@theronin48]

Extrapolating from the starting D-Term rule of thumb where 6S should be 20-30, 5S 30-40, etc. Can we presume brushless 1S and 2S might be in the 80-90 and 70-80 ranges, respectively? Also what would you recommend as a general I term for 65/75mm brushless whoop class? Lastly, I keep reading that P and D ought to be generally the same for whoop class without a solid reasoning. And that D Min is recommended to be disabled as it causes oscillations. Is this what you are finding as well? Thanks man. With sub250 looming, I'm finding that tuning these tiny builds are a supreme pain in the ass lol.

i really need help with tuning my quad, maybe you can give me a rough guess on what my sliders should be at? its a 5 inch xilo phreak frame, 2250kv motors and weighs around 630 grams. running betaflight 4.2 with rpm filter, i just recently built in and i can not for the life of me get it tuned, i still cannot completely read my blackbox logs. i cant tell if i have too much p or not enough, it does not level out back to center the ways yours does in a roll on your logs. current sliders are 1.2, 0.9, 1.2, 1.0 oh and im running it on 5s, maybe somoene can point me in the right direction. awesome videos and thanks!

[@borgslayerfpv]

Good stuff Mark! You nailed it as usual... 👌 Any recommend changes from this particular P/D ratio and tune for a 1S 65mm 802 19000kv motor racing whoop? I've been using your betaflight 4.0 tune from the mob7 for the last 6 months on my 1S 65mm racing whoops, with quite acceptable results... I've recently completed an 85mm whoop build, with 4.1, and RPM Filtering, and I've been blown away with how it flies... So, now I'm jonsin to get RPM Filtering at 48khz rocking on my 1S 65mm racers as well... I'm just hesitant in the middle of whoop racing season... Its just cold here in Maine! 😢 I don't want to go outside, and find my P/D ratio by eye and ear; and, I certainly don't want to install my external logger on a 65mm whoop... Maybe it's laziness, but I just want to rip inside, with RPM Filtering... Can you help a brotha out? 😁

[@borgslayerfpv]

So, I just took my old P/D ratio from my betaflight 4.0 tune for my 1S 65mm racers. Then I just worked the sliders until it sounded right... I just had to see what RPM filtering could do to a 1S 65mm whoop... I'm still interested in your thoughts about 4.1 tunes for a 1S 65mm whoop... However, I wanted you to know that 48khz JESC firmware increased my flight times by as much as 80%! 🤯 You're a genius in my book! 🤓

Still getting the problem. Could setting a static notch help, or is the gyro just likely to be faulty? I can't soft mount the FC, since it's part of the frame, due to Eachine's "clever" design...

As amazing and comprehensive of a guide this video is - it's got to be the most complex tutorial called "101" ever haha ;-) With that in mind, one thing I'm wondering - is why not tune with the new sliders instead? Especially for something like a whoop? I was hoping this video was going to be exactly what it was, but using sliders instead. Going forward, I'm trying to slider tune everything, just makes it so much quicker and easier to visualize for me. I hope you do more slider tuning tutorials in the future! Keep up the amazing work and thank you!

[@uavtech]

Trying to get the point across that all PID tuning is the same with this process. Any size, any firmware, any craft. Sliders don't cover the range needed for whoops (60P and 80D). I helped develop them even. Trying to think how to make them work for a larger range but not get over complicated.

[@protonus]

@@uavtech That makes sense. I just love the idea of the sliders and am trying to use them as much as I can. I would love to see community presets in configurator someday. Better still, imagine being able to enter prop size, motor size, and all up weight and having it start you at a baseline that would work better than defaults! For instance I have a very heavy 3" build on 1408 3750kv motors, that uses 4S 850 mAh for DJI HD, and it's a whopping 344g AUW! Defaults were pretty bad as were most suggested 3" tunes.

just follow the video settings. move up and down sliders based on motor noise, feel or logs after you have RPM and Dynamic Notch setup done.

[@nikotttin]

Fantastic video. Thanks very much! My mobula on 4.1 without rpm filter climbs up the walls as soon as I hit it. What I mean is when flying indoors, if I bump into something, thus stopping the direction it's flying, the controller will over correct and send the quad into the blocked direction. If that happen to be a wall, it would literally stick to the wall full throttle until I unarm. Very likely my tune is bad... But what is the reason to do so?

[@uavtech]

Airmode and I-term windup. Turn off airmode in Anglemode.

[@nitron080]

hello! do you have dump or diff, for whoop like mobula 7?

[@lievenvv]

Thanks! Just wondering; are things like P/D balance not expecting a linear thrust relationship?

[@uavtech]

All PID systems do expect a linear thrust relationship. That is a downfall of a PID controller; but NONONE has a better controller for a quad yet. BF does have a tool, Thrust Linearization, to help make the thrust curve linear; but motor torque curves still makes it hard. Joe Lucid - a BF dev - is has plans to feedback the motor eRPM data back to the PID loop to help with this kind of thing, but it is not done yet. Of course more complex then something like filtering. Nevertheless, a P/D balance is key for tuning a PID controller and that is what we got.

[@lievenvv]

​@@uavtech Thanks! That was partly why I was asking.. Is there a reason that Thrust Linearization is not default? I did try it once, and seemed to work pretty well. It might be interesting if we could make something like a lookup table (or other means) for motor signal vs. response calibration, e.g. using RPM and/or Gyro data. Perhaps even throttle response could be evened out using the accelerometer and a LUT or approximation curve. Curious to learn what Joe Lucid is scheming with the PID loop!!

[@dvmdoc]

Dude is brilliant. Way above my pay grade but great job.

[@uavtech]

1. RpM and sliders at 1.0 2. Paste the CLI stuff 3. Flips and rolls to move P to be as high as possible so no bounceback. 4. Move P and D up together till you get oscillations and then back down. You can do it. :-) easy peasy lemon squeesy.

@@uavtech i'm learning ... what is a bounceback?

[@uavtech]

@@gonebdg , it is defined in the last page of the document. But basically, when you do a flip or roll, it doesn't stop sharp. It kind of passes the stop point and bounces back. See the PDF used in the video, last page for a more extensive definition.

[@boratsagdiyev1586]

Regarding the Anti-Gravity CLI command, is that value lower or higher than normal? I think i get the idea, is it because anti-gravity kinda boosts I-term? And since you configured it for angle mode you lowered it, so it doesnt double down also like high i-gains + gyro. Am i on the right track?

[@uavtech]

Angle mode acts like an I-term for larger pushes. If you have higher I-gains and I-term happens to wind up because you are hitting or riding against something, then it will will have more influence after you have recovered as it winds down.

F3 performance edition branch ? I have a F3 board. how do I do this ? Thanks my friend. do you have a video on this ?

I really appreciate everything you have given to us in your videos and your software work.... However, I am really colorblind and it is very hard for me to see the pid traces.. Is there anyway to assign them with numbers that I could follow? Or something else. I can't be alone on this and I have dealt with my color vision problem my entire life. It may be a little selfish of me to ask for this but if there is anything that could be worked out, it would help me and I'm sure many more... Thank you and keep up the good work!!!!

[@uavtech]

I will keep in mind. Hovering over and highlighting traces I think would help?

[@cs-xd9gy]

If you are able to change the colors of the traces, then that would be great. Some people can only see so many colors, so they may have to change them all to a couple that they can see. Then the highlighted part should work. Thanks!

[@cs-xd9gy]

I just realized, you CAN change the trace colors;) I'm golden now!!!

[@pothead_fpvracing4050]

quick question. these pids are tuned for 2s set up. would the 1s setup just require an increased p-d ratio?

[@uavtech]

Increased PD Gain. Not PD Balance increase.

[@MojoPapiFPV]

Is your outro music Al Di Meola?

[@uavtech]

Not sure

[@Tish0eX]

I know it's an old video but are this tunes apply if you using 48 kHz or should they be further tuned?

[@uavtech]

It was on 48khz.

[@davegoddard]

Please step response chart, and pid error chart. Blackbox explorer freaks people out. I am getting oscillations with FF higher than say 150 on almost every tune. Also whats your favorite whoop flight controller?

[@uavtech]

Try turning up RC Smoothness. No fav.

[@ivanradfpv.4823]

I got distracted by your cat😂 he keeps wave at the back.

[@m7mds91]

me too 🤣

[@nyx574]

Question are you getting logs off the Whoop?

[@uavtech]

Yup. Using OpenLagger

[@rolosaenz]

I need to turn off RPM filtering on a SPRacing F3 Board with BF 4.1.1 , otherwise i get high freq oscilations, BlownSMoke from intoFPV forum is helping me with the BB logs, he is puzzled why we need to DE Activate RPM Filtering

[@embie8350]

Your cat really wanted to be featured in the video... lol

[@Ereqz]

Can you please tune the Diatone GT R369 with BF 4.1.X or 4.2 and RPM Filter? It’s impossible to fly with stock PIDs.

[@uavtech]

I don't have.one, but the setup for all quads is the same. RPM on, adjust dynamic notch settings and move sliders up or down based on the quads specific noise level.

[@vjnmusic2184]

Stupid question maybe: I have a crazybee AIO FC drone. How to get the blackbox data from it?

[@uavtech]

No flash. You can't. You would need to get an OpenLagger like me.

[@imothy]

can you explain how you got logging on the mobula7 board?

[@uavtech]

kzbin.info/www/bejne/m4CVmXyIp9R5idk

[@DT-ph2ip]

Hi! are mobula 7 0803 12000 KV engines suitable for 2s batteries

[@uavtech]

Yes, but it is near upper limit. 4v x 12,000kv = 96,000 rpm! Go light on prop pitch.

[@nathana5379]

maybe I missed it but how are you getting 2khz blackbox recordings on the mobula7? Insert memory card where? lol Do u have a seperate blockbox recorder that you soldered onto a uart or something? Link to product?

[@uavtech]

Yup. Google OpenLager

[@nathana5379]

@@uavtech i remember hearing about data loggers in the past but i thought they were capped at 500hz recording rate because of the uart speed or something to that effect. Cool man I will do some more research on openlogger and order one tonight! Thanks!

[@uavtech]

OpenLogger, yes. But not OpenLager. I have recorded up to 4k

[@JuanRodriguezArchitect]

Bossman....question: so what's the point of having the ability of modifying "D" term , why not have P and a ratio slider? So you tune P and adjust the ratio. I would assume the ratio can't be bigger than ..5 maybe. Wouldn't that be easier for tuning?

[@uavtech]

tuning with the sliders is intent to make it easier and reinforce the concepts of P/D ratio, etc... However, slides doesn't let you vary Pitch vs. Roll for a whoop and doesn't give you range enough to get the tun i came to here. Sliders are more for fast 5" tuning, but when you get into a more detailed tune, the intent is to leave them behind and move up to the PID grid.

[@imadabualia4843]

My newly built micro quad has way too much current draw. Constantly pulling 15+ amps. I can’t fix it. Anyone can help?

[@Tim-Shows]

Where can you point me to learn Black Box logging for BF 4.1?

[@justhackitfpv]

Can you make a video showing different levels of noise on different setups like 5" and 3" and whoop size i think you already have Blackbox data and also tell us till which level of noise is acceptable

[@uavtech]

It all varies based on your D-gains. High power to weight rigs need lower D-gains so can be more noisy. Low power to weight, vice-versa.

[@justhackitfpv]

@@uavtech so does this mean a 3" or 2.5" will have more noise compared to a 5" ?

[@uavtech]

@@justhackitfpv , yes they could easily. It all depends on the power to weight ratio of your 3" and 2.5". Also, props suck for small quads compared to 5". So it is critical for the little guys to have the right props first. Then look at noise, etc... "The right props" are the ones that don't produce a lot of vibes. For my 2.5", it had horrible vibes on GF 2540 props, but then i switched to HQ65mm props, it was awesome afterwards. It is ALL about the props on the little guys. If you don't know which ones are right for you, order a bunch and try them out. That is what I did, but happened to land on the HQ65mm right out of the gate.

[@justhackitfpv]

@@uavtech what a coincidence i have the same prop and high noise level thanks for this tip... Albert Kim also mentioned this but it was very brief so i didn't thought about this

[@alexanderkerner9669]

Did you try 48khz PWM on your whoop?

[@uavtech]

No.
