- Hi everyone,
I absolutely love how the BOB57 quad flies using both the factory well as the the EllisVanJason PID and Rate profiles in Betaflight.
Unfortunaterly, BTFL has several drawbacks compared to INAV, e.g. useful navigation modes and a reliable RTH function where the quad doesn't just drop out fo the sky.
To get the BOB57 to fly with INAV, I performed a series of PID tuning flights using the "Basement Tuning Method" and in this video I am showing you the results of extensive tuning to achieve near perfect flight performance.
I hope you enjoy the video and get to learn something new!
All the files that have been used in the making of this video are stored on Google drive here:

VIDEO PART 1:
i expected complete INAV PID tuning work flow from specifically your side as no one covered it . as one part of it you have excellently explained,appreciate your work for community!
I honestly struggled, I love what you said in the beginning, no clue what you were doing trial and error. Your video made this so much clearer than any other video I have seen and watch tons !!
Although my basement is 1/2 size high, I used the spare bedroom, after breaking the fan and lightbulbs 😂 I came to realize I didn’t know what I was doing either !!! Then realized you can’t tune in angle mode 🫣. Although I was tuning the gps pids , somehow got that workout really good ! Now to tune the main pids, but will probably do that outside. I used your pids for reference, although mine is the axis 7 kolas 7”. I came from betaflight as well. I’ll probably have to watch this video another 2 more times following along with you and hopefully get my main pids down .
Bro I don't care how long you make video you can make it for a full day. I am here to watch. Just tell the information ❤
Finally there is something very usefull. Thank you for your efforts.
Nasil yani,2024deyiz bu cok eski zamanina bile ardupilot automatic yapiyo bunlari
Clear as mud
Thanks for this
thanks
Actually that was a very good explanation
Do you have any suggestions how to tune bigger quads indoor, like 8-10"?
Is methods and suggestions described here will apply for lot heavier quads?
Will try to follow it and hope I'll finally will have adequate tune for my setup.
Bro please make a video how you installed and use blackbox step by step for inav. Mine says insufficient data
When I get the time to do it, I will. I have none of my drones with me at the moment.
Do you find solution. I have same problem
Thanks for the info. I’m actually building a Bob57 now trying to decide between beta flight and inav. I’m leaning towards inav. Do you feel like you have it dialed in now?
Absolutely, my last PID tune was excellent. I had no nasty surprises at all!
Could you share your tunings settings of pid etc? I plan to flash inav to my bob57 that would save a lot of time
The link is in the description, but here it is for the latest version: drive.google.com/drive/folders/10_idXlHsSvQfESs_36yqbrwMy9bdj17o
You can copy the DUMP file safely into INAV 6.1.0 wihout the gyro and accelerometer settings. Just make sure you callibrate your compass after setup and you have your GPS mounted FLAT towards the sky and not at an angle!!! This is very important!
@@DZARO awesome thanks a lot!
@@leomatis_ No problem, glad I was able to help. :)
How did you get the m10 mag to work? I copied your file and settings and it’s not recognising the mag
Thank for sharing your research : it help me a lot with Inav7 Tuning,
Could you confirm the method to have a good PID tuning :
1- set I and FF to 0
2-put a value on P (40) and keep it constant
3-log a fly for each value of D (from 15 to 30 ie every 5+)
4- choose with PID Tool the right balance P/D
5- keep the P/D ratio and multiply it from 0.6 to 1.4
6- chosse with PID Tool the right P/D
7-play with I to see the effect on PID Tool (not great for me...)
I'm at this point on this method and then try to play with FeedForward but not also great effect ...
What do you think ? what is your method to define the right PIDFF value ?
I'm not happy with the new Ez-Tune for Inav7 ... or I have no idea how to use it ...I think it is way better with Betaflight slider...
In essence, yes, that is correct. It is an interative process and you should learn to listent to the motors and props and how they sound when you make sharp and short stick inputs.
The other thing that I did after this was something that I wanted to make a whole different video about, where I show how to do tuning in flight. This one is all about what you see in the goggles and what you can hear, not so much about graphs and all that. Graphs are usefull to get you close, but they don't represent real flight where you can have disturbances from wind, turbulent airflow etc. because they are made in "ideal environment".
I'm looking to make that video on the next few months, probably around Christmas, when I'll have a bit more time. This will be specifically about tuning a quad in INAV. It might even be a two part video....
So all I have to do is push throttle several time to get good data?
Not really, you need to push the trhottle make aggressive movements in acro mode which will have you using the full length of the stick. You need full throttle for filter setup and to check for prop and frame vibrations as well as resonance.
Man you open my mind on Inav and basement tuning. I'm used at Betaflight, however on Inav I have a lot of questions on how to realize a good tuning , it seems that PIDs are so different from Beta. I usually set I and FF to zero, enable 100% angle strength and use angle mode not acro as you did if I'm not mistaken. I start leaving P to stock and start moving D. But with Inav it seems different, is it possible that stock P on nav is too high ? I'm tuning a a deadcat 7".
Yeah, that is possible. I had a flyaway when I used the Betaflight PIDs in INAV (only the ones that Pawel reccommended). I don't think he is correct in his advice. Every quad is different though. If you have specific PID that you would like to improve, just join my Discord: discord.gg/HkFBVHvz
How could u open a text file in pidtoolbox?
What is the Facebook group you talk about there is no link.
Great Vid!! one question.. did you made this in angle mode or acro mode?
Acro!
@@DZARO Thanks!!!
What is this log viewer is caled ?

@DZARO thanks
Any tuning tips for filters and pids for a custom 8"?
@@theinventionshow Start with low values for all P, I, and D. Gradually increase P and I until you start seeing oscillations. Then increase D to try and remove those oscillations. Finally, dial down on P and I to get rid of the overshoot hill and that's pretty much it I would say. It's not that hard tbh...
I watched the video. Very interesting. I think I'm having trouble optimizing the filters. Can you give me some pointers? Thank you
Sure, no problem, can you send me an image of your PIDs in Betaflight and an your Black Box log? I suggest using wetransfer.com for sending the files. The link will be available for 30 days, so I'll see it :)
@@DZARO Thank you. I don't use Betaflight, but INAV 6.1.1. I'll do a couple of test flights tomorrow and send them to you with a picture of the PID settings. However, I don't have his email address; can you give it to me?
@@waltertomazzolli5877 You don't need my email for this. With wetransfer.com you have two option, sned files via email or get link. If you post the link, I will be able to download it in the next few days. Can you try that?
As far as i know Powel advised that I and FF can be copied..not P gain
Yeah, well, Pawel advises many things and I don't agree with some of them. Pawel aslo advises different things in different videos, which makes his advice even more confusing and less trustworthy.
If you try it stock I and FF, on this quad, I guarantee you that you will have a flyaway event and you risk burning your ESC.
You can trust me on this one, I've tried!
