Just converted a quad from Betaflight to INAV and this is super helpful in understanding the new NAV mode features and how they work. Much appreciated!
One way I like to think of the gains is, P gain makes the loop respond to how far off you are. D gain acts as a break on the P gain but is sensitive to noisy inputs, it can catch and break the response of the P gain before you overshoot assuming you have a clean input signal. The I gain is good for removing steady state error. Just how I have always viewed the gains. Just my two cents.
Another great video, thank you! Was wondering can you please try to tune big drone, like 10 inch drone for example in INAV. in general and navigation. It looks very challenging comparing with small drones. Even RTH is tricky because of excessive vibrations which usually leads to Dron rapidly gain altitude in RTH even on pretty stiff frames. Also making it fly great in general is also tricky
Great video man !!!. Was waiting for this. Will surely help as atm actively playing with tuning rangefinder based alt/poshold on 2 diff quad types. You gave me some good pointer to look at.
p.s. One tip , but pretty techie but surely usefull for you during your testing. What you can do is put all the OSD element on screen like you did , but then setup some nifty open-tx (or in my case freedom-tx) programming to drive selecting and adjusting these parameters IN FLIGHT . You use the programing page for that in INAV configurator and a few free channnels. I have a 2 position switch to switch between selecting the parameter to adjust and then the other to adjusting the parameter, and 2 momentary buttons to inc or decr the selected value or select the prev/next value to adjust. So without landing you can immediately see the change in behavior of the quad. It take a while to set up but is massive and impressive to play with. I was afraid to push the P too high as was reaching crazy values , but seeing you reach the same and confirming its not an issue in itself hepls me a great deal and i can do some more finetuning. Again keep up the great work !!!!!!!!!
I need to tune mine. Use to not be too bad. But seems when hover throttle is off cause battery weight changes drastically. Other day was just slowly sinking for a little bit before got under control
how about "I" for "imbalance". we have p for push, d for dampen, but not a great word for i. imbalance is the best i have come up with so far and it's pretty appropriate since the i term controls imbalances in the quad.
Hi did you know why INAV cannot detect my M181 Walksnail Compas? I already plug into the socket to my Speedybee f405wing (SCL &SDA already connected) I heard that if I want to use Altitude Hold feature in INAV I have to activate the Compass
No compass needed for Alt Hold. Only for decemt Position Hold. Set Mag to AUTO in Config. page and Save & Reboot. Make sure correct port in Ports tab has GPS selected if Compass is on a GPS Module.
Scariest things that happen to me whilst using inav is engaging rth then quad kinda ignored throttle value and will keep at 100% throttle to a point makes rth pointless as the battery drops insanely
Ive also gone through adjusted my altitude gains as per your video and made it really snappy compared to before so yeh overall good quad, i also remember to mention to you that there is a way to limit current to motors maybe you could dive into as a video
hi… I set the loop time to 1000 in the inav 6.1.1 CLI, and therefore having set the black box to 1/1 =100; I get the frequency range that goes from 0 to 500hz... now how do I get 1000hz instead? I set the looptime to 2000 in the CLI, but I get 250hz, not 1000hz…🫠 Thank

You would be the coolest neighbor ever, my bro. Cheers!

You should really make a series of these fantastic videos without caring of audience.😊❤

Yes this.
Nice, I was waiting for this one, thanks!

How do you set the deadband for your throttle stick in altitude hold?

Great instruction!
Would love to get back into this! I have been fascinated with flight.... Too much government control.
Thank you.

that's a great word for it!
Altitude hold & positon hold can be used on same channel mode? thx
When you engage POS Hold, it engages ALT and Heading Hold as well.
but in the blackbox explored of inav, the graphic frequency vs throttle, where is it? thank
that is not available in INAV BBE. That was added to BF a few years ago, but not INAV. Not sure who added it. Would need to look.
@@uavtech thank you so much
Hi did you know why INAV cannot detect my M181 Walksnail Compas?
I already plug into the socket to my Speedybee f405wing (SCL &SDA already connected)

Set Mag to AUTO in Config. page and Save & Reboot. Make sure correct port in Ports tab has GPS selected if Compass is on a GPS Module.
@@uavtech hi thank you for your information
It was my bad
I thought I need the compas for my RC Plane
I will disconnect the SCL and SDA cable
Scariest things that happen to me whilst using inav is engaging rth then quad kinda ignored throttle value and will keep at 100% throttle to a point makes rth pointless as the battery drops insanely
YIKES!
Wonder why. Did you try again after (on a switch) and log it?
@uavtech i did a flight still havent checked logs but only did it once, i will how ever check now that you mention it 7 inch quads so funn
Ive also gone through adjusted my altitude gains as per your video and made it really snappy compared to before so yeh overall good quad, i also remember to mention to you that there is a way to limit current to motors maybe you could dive into as a video
i got zeee log how to share with you sir
discord. tag me a ref to these comments.
NOPE! :)
Inav have no autotune like Mission planner ........
It's INAV not iNAV 😂
iPod, iPhone, iPAD, iMac...
... iNAV!!!. 😜
@@uavtech I is for Inertial not whatever apple decided it should be ;)
You never know.

Thank
Nyquest Limit (look it up).
To get 1000 in graphs, set loop to 2000.
