This series came out at a very good time, my son in law is getting ready to install iNav on his 7" build. Thanks for sharing. 🤓
Fantastic, Pawel! Thanks a lot! 😃
Stay safe there with your family! 🖖😊
This helped me allot. Thanks for clarification on the calibration process.
Hey Pawel, great work. I saw this video thinking I have seen it before. The whole playlist is in your video description.
Just think of all the people, me included, who have INAV quads with the GPS/Compass angled down in TPU. Groan. Great video series! Coming from 2.5.2
I've just loaded iNAV 3.0....Looking forward to the new features...In particular constant flight trim on FW setups... Great work Pawel...🤨😳👍👍😄🇬🇧
I´,m ingeneer too, trust me when i got my vista/Polar Kit and the gps with compas of course i built my first 7 inch INAV Q.
Thanks for the info , not a big deal to swap over from bf.
Hi Pawel, I see the Speedybee F7 v2 target is coming soon in Inav 3.1. Thank you for doing this.
yes it is
too good.....!
Hi Pawel, a guide also on building would be appreciated, the tip of put the gps unit not tilt but flat i didnt know it , thanks
Hello Pawel
Should the magneto be calibrated with the Gopro on and the lipo plugged in? Or does it not matter?
Thx for your great videos.
Privet Pawel! How are you? Very clear your video. Thanks! Question... at the setup tab, and after calibrating the Magnetometer, when you move the model... The representation of the model in that setup tab is exactly the same position in which you have the drone? Or the magnetometer is like it forces the orientation a little different?
(I will do what you say about doing the calibration in open space away form metals)
BUt, I have a Fixed wing and for example, If I move it 90º to the left... at the setup tab I see not 90º but 45-50º (and like it tries to back even 30º or 20º). This, without magnetometer sensor not happen.
Is it clear my question?
I am wondering what happend last weekend that when I set angle mode... flip and crash. After that.. only manual mode :-)
Thanks Pawel!
What does the flip 270 mean, what does that adjust if you only need to adjust yaw to get correct orientation
Hello, Pavel. My FC is set according to the arrow on the board. GPS is installed with an inclination of 25 degrees. I have manually fixed these settings
settings align_mag_roll = 250
set align_mag_pitch= 1800
set align_mag_yaw = 900
On the SETUP page, I tilt the drone forward, then the brick tilts down and turns to the right by yaw. According to your video, should I change the FC orientation? Is it right?
what's that yaw setting for? how bout if you have the mag tilted a little as well?
calibrating the compass is easy now with that speedy bee phone app, just keep messing with it til it matches a compass.
hello, is it normal that after calibration the drone moves a little on the setup screen? while it is placed on the desk without moving physicaly.. and in the sensor page, the accelerometer is stable and does not move either?
Hi Pawel. i thought lets get one of my 5"quads migrated to inav 3.01, all is well, i have a Iflight Titan XL5HD and have removed the standard gps and replaced it with a matek
M8Q-5883 the one with the Compass, now i have a question, I do not have DA and CL on my board ( succex-d f7 twing v2.1
) I have looked in the cli and found out the CL and DA are on TX3 and RX3, (where my gps is on) so i desoldered the old GPS and soldered the DA on the corresponding Uart port and also the CL, and moved the TX on RX to uart4 and RX to TX on Uart4 for gps, In Inav the Magnometer and GPS are Both Blue But i cannot Calibrate my Magnometer.
Is there a CLI command to activate the magnometer on Uart3?
I hoped you might explain correction for roll degrees when the FC is mounted upside down. It took a fair bit of research to find the CLI command to correct it. Was there a particular reason why it was left off the graphical interface? These blow by blow videos of yours are magic; between you and Joshua Bardwell I manage to bungle my way through the setups. Many thanks.
we have a new policy to remove from GUI settings that are not frequently used. And mounting the FC upside-down is not something that many people do. So it's gone
hi care to share the cli command you used? i cant seem to find it in my searches - also need to mount my fc upside down under my glider - only space
@@FPVUniversity Sorry but this policy is just stupid.. The least you could have done is included a link to a wiki or something on the GUI that explains HOW to correctly orientate it... not just 'it's gone', 'refer CLI' as per the GUI... yeah CHANGE WHAT IN THE FUCKING CLI ??? There are hundreds of items in there and they don't even list in alphabetical order to make finding things easier... We're not all programmers mate...
I occasionally mount my FC's upside down/rotated for clearance issues on tight builds (in this case). I came to this video after watching 3 others hoping to get an easy explanation on how to fix it instead I find this bullshit half--arsed non-answer...
To see if your compass is correctly aligned you can enable in the OSD tab heading graph, now if start the quad you should see where the quad is pointing ( north, south.. ) compare with another compass example on your phone and should point the same direction, if not change the degree. I went trough hours of trying before figure out, without the compass align correctly its impossible to fly!
hello and good day.... can use the fpv flight controller and use for drone 500mm frame size motor 3806 700kv propeller size 12 in esc 40A for each motor ..TQ
Pawel where can I find the GPS .stl file for that GPS mount ???
my goodness who labelled these settings 270 flip! gut him for being a smart ass!
That's because the magnetometer in aligned 270º CW and upside-down in relation to the arrow by default if the GPS is pointing forward.
The default assumption, by engineers, is that a pilot will fly off into the sunset. ;)
Dear sir please make a video on Hglrc m80 pro gps and help me because on this product not mention the front direction thanku
What is the best way to calibrate the accelerometer of a dead-cat framed quad? Since the front arms extends further, it is difficult to keep the drone level for step3 and step5.
I use a tablet, with a two axis spirit level App. I use the edge of the tablet as a straight edge, and use the motor screws to hold the copter against the tablet, as I go through each step. If you don't have a tablet, any two axis spirit level and a jig would work.
even I made all the calibrations, inav still shows my drone upside down? what should I do?
Hello, i have the Frsky Pilot Flightcontroller, when i arm the drone the gyroscope get crasy. If i start all motors with INAV software ,the motors have the same speed and vibrations but the gyro work correct. I i arm again, the gyro gives out wron data. Does anybody know a solution?
My GPS mag/Compass sits bend forward slightly cause i crashed once and landing upside down when changed modes. Will the calibration resolve the Compass sitting forward, or will i have offset certain values?
i was having a problem setting up the Magnetometer (values where not saving fully through the calibration tab) with 2.6 config as i can't use 3.0 for BrainFpv our working of their forked version of Inav 3.0
Ok, slightly confused. Calibrated my compass several times. My X value is always in the -800 to -900 range. Y and Z are always close. Tried several compasses with the same result. Compass/ GPS is Holybro Nano M8. I assume this is why I constantly get drift in GPS hold.
Any advice from anyone?
Hello I can not calibrate it comes up upsidedown, and I cant change it
😬no arrow in my beitian be880q
my mag, is not turning blue. did many time calibration still nothing x , y , z showing 0. using 880
Hi Pawel, my compass calibration show the negative data on ZeroZ (-840), it is normal ?
No, this is not normal. Either compass is too close to the metals, sources of magnetic fields or is damaged
@@FPVUniversity My Gps M80 Pro HGLRC is New
The airplane model picture on the "Setup" tab doesn't look like my ZOHD Drift at all.
# get model_preview_type
model_preview_type = 14
Can I see the correspondence of these codes to real pictures?
But why should it look like your Drift?
@@FPVUniversity I just want to see the possible options for the pictures.
one question: what is the exact use of magnetometer on a quad? what to expect to have a magnetometer? how to use the information given by magnétometer? i don"t see any menu/option, except the activation and definition of the ùagnetometer.
Quad has to know where north is to be able to navigate. When it's moving above 5m/s this comes from GPS. But when it's moving slow or stationary, this comes from MAG
thanks pawel@@FPVUniversity
What am I doing wrong?I've got a recon 7 pro. My gps hglrc M80 pro doesn't have a direction arrow so I tried all the options in Mag Alignment from default to cw 270 flip and still in the heading setup it doesn't hold the position very well and when I try to tilt the drone it also rotates. Thank you
Probably MAG is too close to the source of magnetic field. Move it firter away. Rule of a thumb is 5cm from motors and wires
@@FPVUniversity it wasn't the gps distance. my angle setting for mag_roll didn't work. my default value is CW270FLIP and for my quad this works mag_roll=0 mag_pitch=1550 mag_yaw=1800
@@j1o2h3n4y1so you had to make changes to two of the three values? I’m attempting to setup the compass on my 7” long range quad and the gps/compass sits in a TPU holder that has a 10 degree downward tilt. CW180FLIP with -10 degrees change to the Roll is the settings I’ve found to give the least drift. I’m using iNAV 6.something.
The Board & Sensor alignment disappeared from the Configuration tab in Inav 7.1
There is new Alignment tab that is the only thing you need
@@FPVUniversity ok thank you. Just needed to ensure they were the same.
A kiedy cos po Polsku ? 😃
