Just built my dream quad. It’s bright blue skies and Bardwell releases a tuning video right when I need it.... too many things are going right today so my drone will definitely explode.
@@nolacross704 nah found a session 5 in perfect condition later that day on Facebook marketplace for $150. Flew 30 packs on a new drone with a new cam. Damn good day. May the Gods of sbang bless you all as well.
Joshua, you are the reason I'm still flying after 4 years man! I'm sure without all of you priceless info I would have long since gave up, somewhere along the way. You're a big part of this killer sport/hobby and are in the fpv history archives, for sure. So, thank you for your invaluable contribution dude! Long live the info king of fpv, the know it all, the guru, Mr. JB!!!
I'm watching Chris his videos for a few months now, and even though I don't fully understand everything he says, it really helps me to get a grip on what I am actually doing with pids, filters, etc.
Thanks a million. This really helped me dial in my Banggod 5 inch. Also, your alarm going off while you fly and try to talk over it was pretty hilarious.
The biggest help for me in learning what the P, I and D do is a video called "PID demo". A guy (Horizon 4 Electronics) made a box with a pointer that moves left and right. It had knobs for P, I and D on it and when he adjusts the knobs you can see what each one does and how it effects the pointer.
I don't know if anyone has told you this, but I feel like your flying has really had a breakthrough lately. You've always been a good pilot in my eyes, but some of the moves in the first part of that video I've never seen you lace together. Great flying brother!
I followed his tutorials to tune my newest Betaflight build and my quad is flying amazingly well. The stock settings in Betaflight just didn't work well at all for me, I was having those low throttle wobbles and instability after flips and rolls on stock, but after following his tutorials the quad flies amazing now.
The coolest thing about Bardwell doing this video is that Chris is going to Blow UP in this hobby! Thanks for yet again sharing the love to others in the hobby. You have always been great about giving props to people with talent, as well as helping to build up those who deserve it
It's been great to see the "banter" #short video's recently between you guys! But can clearly see how much respect you guys hold for eachother! Thankyou both for your Fantastic videos! I learn something EVERY DAY from you! Thanks for sharing the knowledge.
This is so good, things are getting so much easier for people tuning their quad. Big Thanks to Chris and you Josh, this is gonna help a lot of pilots flying a good quad!
Thank you for doing a companion series to Rosser's simple tune vids. Can't wait for the remaining videos in your series to post. I think the other folk(s) that make these tuning help videos are prone to talking over the heads of us non engineer types.
Good point. You know, after one gets to a certain level of ability, one realizes that 'proximity' skill is really what defines accomplished, smooth, all around captivating flight.
Holy shit, I learned how to fly on Chris' plot, in the simulator Liftoff. Didn't even know this was a real place. I was really proud when I managed to get into the shed for the first time!
I took my AOS5 v1 apart down to the frame, to begin a tune for the start of next season. Turns out I have been flying with a broken arm all summer. If it was not an 'A-arm' style build, it would have not been in the air at all. I'm glad I took the time to go through the first step. Even though, it probably could have gone on flying with no flight-ending failures, Chris's design kept it from failing, but with that fracture, I would have been chasing my tail trying to find what the resonance was coming from. Now. New arm. New Season. New Tune. Three months till spring here, can't wait for the new year! (yes, new year starts on May 1st, lol)
@@ugpfpv361 I found P at about 75 and D at 45 is my sweet spot. with 150 FF. I reduced all filters apart from the D lowpass @ 100hz. cool motors after 5 packs
I put the same filter tune on my 110g 3 inch and heavy 3.5 inch. Both of them fly amazing. I was trying all sorts of pid changes before and was a bit stumped... Now stock is nearly perfect for both.
for the Dynamic Notch Filter Tab, I don't have a Dynamic Notch Max Hz but instead I have Dynamic Notch Filter Range it can only be set at AUTO, LOW, MED, & HIGH
I haven't heard anyone mention the fact that you can change PID profiles via the OSD. Is there a reason you wouldn't want to have one "aggressive" profile when your quad's in good shape and then a second profile that you switch to when you crash and need to fly back home? I'm guessing that's because some of the filter settings are independent of your PID profile?
The gyro filter I think is outside the PID profile. Realistically the reason I that most people don't want to think about switching they just want to fly.
A single biquad isn‘t appropriate and most important a biquad causes overshoots. Thats why ctsnooze came up with PT2/3 filters and before that the bf defaults were set to two PT1‘s.
first off we love Joshuas videos and follow every word.So I heard you say tune on old props,my problem with that is if the props are worn or weighted differently from being worn or even knicked .It will make every prop different and screw up your tune.I get your reasoning but I believe you should start from perfection (as close as you can)as the props get old you will feel problems and know better when to replace.We would still be stuck on camera drones if it wasn't for Joshua.As it is we have about 20 succesful builds and many more prebuilts and we couldn't have done it without your help.My common sense says you might be wrong on this and since so many of us follow your every word please prove me wrong,lol Thank-you
Awesome video. Thx for sharing this criss Rosser magic. Apart from that.. Damn Joshua. You became an incredible pilot. Back in the days I always watched your videos for the latest information and stuff but damn.. Now its even more enjoyable since you are absolutely killing it at your home spot. Much respect
Thank you for all you do for the hobby. It's just such a shame that anyone getting into the hobby, can't because of the absolute evaporation of inventory available to buy. It's like a steakhouse with no steak.
There's tuning for performance and then there's tuning for longevity. Reliability can be built into either side of the spectrum but if you play chicken with the edge of performance envelope, it begins to become unreliable. Tuning for performance shortens lifespans of components - make sure you can sustain the cash flow for that tuning. Ask any car tuners. I think Betaflight presets lean towards longevity and reliability - easier on the wallet and increases flight time over bench time. Looking forward to the rest of the series!
When seeing the D-gains-first approach to tuning I wonder where I should stop. I must think about Bob Roogi's statements about how even moderate motor temperatures compromise power output.
@@Gosuminer exactly. it could be shown on osd instead of esc temp or other value. of course this would be a bf fork at first but could be accepted by devs if used enough.
I followed these steps on a GEPRC mark 4 prebuilt(They somehow give me a prebuilt quad with no factory tune). But then I keep frying the left front motor when i was tuning D term, the other three are just fine and cool. I sent it back to their shop for repair all they did was to replace the motor and put tune in, then the quad was flying fine. I recently find a lot of prop wash on it so I kind wanna follow these steps and retune it again, i find out they have crazy amount of filter in their factory tune and pit loop time of only 1.6khz. So I raised the loop fz to 3.2(they have slower gyro on this one),and reduced to the filter setting by the recommendation of this video. Immediately I fired the left front motor again with a 360 row, I really couldn't figure out why It seems to act nomarl but keep frying the left front motor the moment i try a flip.
Yup, thanks for sharing Chris' info. An important thing to remember is that betaflight defaults are intended for a 550/650g 4s build carrying a gopro... So yes for a heavier build it is advised that you increase the master.... For a lighter 5inch builds, its recommended you decrease the master... At least to start with.
Josh you have gotten way better at flying ever since your 3packs a day series. Just saying.🙌🔥👏 I'm very interested in trying what you're doing here on my build that you connected to your laptop at Rampage. It was the 5-inch player one with a iFlight H7 beast toothpick board which is 55 amp mine would really be pushing the limits though because I'm using it with 2206.5 2550 KV Tmotors on 4S. I've been flying it lately doing speed runs and it's working great with stock beta flight setup but I like pushing limits so let's see how it works... Looking forward to part two and possibly three 🗣️💯 Also if you haven't already a link to those stick overlays would be awesome
If I tap like twice, it goes away. If I tap it a lot of times, will it count the total? Good stuff, appreciate you being there for us. Your skills are rocking now, bub.
This comment is not meant to sound like I'm bashing BetaFlight or Emu but the combination of FETtec FC/ KISS FC coupled with a FETtec ESC gave me results like this out of the box with very, very little change 🤷 Again, not bashing it and not everyone can justify KISS/ FETtec but it is bloody good. The tune on this quad at the beginning looks mad though JB! Nice flying
hey brother thanks for takeing the time to help me out yesterday for my BIRTHDAY ..josh i just will never know how u do all that you do ..Thank you so much for making this hobby accessible ,with out you i could of never done this hobby..Once again the video was awesome thanks again.... SANDYDOG_FPV
great video the day that the usb connector goes away and a more robust connection during the tuning process would be sweet. sure mostly my ham fingers, but haven't broken a usb conn on my phones; usually the cord wears out first...just beeching
You were so nearly in the tree at 2:30… you had no idea where it was and then styled out of it into a power loop! 😂 (I only know this because I do that kind of thing all the time)
@@JoshuaBardwell yeah I totally agree. There’s blind moves and then completely blind moves where you really don’t know where you’re going, just that something is there and you need to get away! Keep doing what you’re doing anyway, Joshua. I’ve been doing fpv for almost as long as you have and you’re one of the view channels that I still follow.
completely unrelated, but I see you got a trampoline bed on your backyard, have you ever tried to crash a quad in it and then recover the flight mid bounce? that would make a fun challenge :D
I wouldn't. Props could and likely would shred the matt. That could cause the threading in it to unwind and whip springs around at high speeds. The whole thing is under significant tension.
Need to compare Chris' approach with UAV Tech's approach. I've just tuned an Apex with UAV techs, it flies really nice, I bumped up the master slider one notch and I like the feel of the increased I gain, but took it back down because he says to leave it at default. I will try tuning it again with Chris' approach on a new profile and compare them, but a video from you doing the same would be great too.
I really like this way of PID tuning, a lot of tutorials on pidtuning are basically "I feel I need to up/lower X based on how I feel the quad should move. Just avoid hot motors". Which in all honestly is pretty useless metric seeing as a viewer like myself can't feel the changes by watching a video, let alone have the feeling to change certain value without it being just a whole lot of blind trail and error. And at that point is such a tutorial really useful? This data driven way of PID tuning is quite useful as you remove most of the guess work and don't need to base it on feeling alone.
I’ve played with increasing pidsum_limit from the 50% default to 100% and I found no real advantage in pushing the pidloop any harder. Motor saturation is already a problem at 50% pidsum_limit, increasing to 100% will not improve anything really. I saw a comment by ctsnooze in some PR somewhere where he also corroborated this
According to Mark Spatz, the reduced pidsum limit was designed to help deal with iterm windup, which is now solved by iterm relax. So raising the pidsum limit allows the motors to go to saturation when needed, and doesn't have a downside. I don't know who's right because even if I tested all of my quads, that still wouldn't be as much research as is needed to draw a firm conclusion.
i hate u. 😂 This is why I wait to watch. So I do not have to wait for the next part. One time I jump the gun, gotta sit on my hands. Being in the middle of repairs and builds, I have plenty to do. My gopro is temporarily out of commission, though, so I can't film anything. i hate u. 😂 Cheers JB!
Hey brother, I just built a xl10 v5. It’s flying pretty good so far but I can’t figure out why it has low throttle shakes. When I get down low say to land it’ll shake a little. Thanks Joey! I enjoy the videos
Is it bad that I can easily come up with half a dozen people who are in unrelated fields who are better at this? To be fair, Chris is awesome, and doing a great job with the FEA V&V and making useful stuff happen... but there are people who haven't spent time producing youtube content who do it better
@@JoshuaBardwell That's exactly it, and why my content isn't in this area - I just can't put explanations at the right level, it's just middle school or grad school, whereas you, Mark, and Chris do a fantastic job of that. Being able to make troubleshooting seem logical and well-ordered, that's why you're full time. Plain and simple, you make this sport accessible to not complete nerds. It's arguably insane that Chris can actually make finite element analysis VV&A something that can actually be a popular discussion topic, which is crazy. The discussions I've had as an output of that, including some with Chris, have been intensely enlightening as well. I guess I'm grumpy about how much I'll be trying to put out fires in a few groups and discords with people who are following about 80% of this method and having all sorts of problems with it. No intention of gatekeeping on this, but there will be some growing pains with getting all of that work, and SliderGate was kinda an extension of that.
I’m going to learn something YEAAAHHHHH!!! 😃😃😃😃😁❤️ Rosser is a dreamboat of technical brilliance, of course everyone knows who he is but the “Yahoo/suck it and see” approach to FPV tech works well too 👍. This message reads a little…gay…🤨 It’s not intentional..😏
I'm surprised we haven't seen an auto tuning FC already, surely it can be done where a computer is analysing the blackbox data and making adjustments as you fly. I don't know, could be wrong!
Nice job on these videos. In a couple areas you used the term "hitches" as a descriptive term (among others). I'm not sure what you meant by that or what you were pointing out. In that specific scene I saw what I interpreted as oscillations...but I'm not sure if that's what your were calling out. One bit of feedback... If when calling out items like this...would you be willing to use more accurate descriptive terms so we all know exactly what you are pointing out? Maybe what I'm asking for is difficult to explain.
