Great helpful tip. Thanks Lee. Timely as was trying to setup a new gps with integrated compass on my Flywoo Explorer this last weekend, and like you was confused. Can confirm this works. 😃👍 Originally was setting the offset as -10º, as compass(and integrated gps) is mounted at tilt -20º in pitch. Was thinking better to use "average angle" between when quad would be level (in hover) and assuming 20º pitch forward in normal flight. However, after watching this it sounds like the offset is the difference between the FC (INAV) orientation and the GPS/compass orientation. So compass alignment should be set at -20º.
You're very welcome. This has stopped lots of us with INAV builds getting the thing into the air with the GPS/Compass stuff working! Best of luck with the maiden!
Update: always remove props before modifying stuff in iNAV. My Source One flew through my hand I lost a prop too... No serious injuries, so that prop might be the disappointing part... and the midnight ER visit...
I can not tell you how many hours I spent trying to figure this out:( . I tried so many combinations but never got it working. At the end I just 3D printed a new flat GPS holder and it works good, but I always had the feeling that INAV beat me. Thanks for sharing this.
Tip: If you cannot figure this out, especially on a board with atypical magnetometer placement (with no directional markings), use XYZ mode in INAV magnetometer tab (new thing) and look up datasheet for that magnetometer (note the dot in a corner). Write down that orientation with XYZ arrows on a paper and match it with your magnetometer (rotate the paper) and then match it again in INAV. Next do the compass calibration and it should be working.
Excellent discussion as it was not intuitive at first. Thinking of the perspective of the compass chip orientation, it makes sense that the roll is -20 degrees for this drone model. Seriously considering getting the Rekon 7 LR with DJI air unit and using INAV
@@Painless360 😂 luckily I figured it out. There is definitely a lack in useful quad info out there about iNav. Tons of wing stuff, but, not a whole lot about quads.
@@Painless360 would you suggest having the compass at a similar angle to what will be flown if your goal is to have a freestyle drone that has an emergency button? I built my 3d mount flat, because I was having toilet bowling when it was at an angle. Now that I have this knowledge, if there is a benefit to having it at an angle, I may switch it back.
There are two schools of thought. I've used both here and both have worked great so I just set it up for the compass/GPS mount the model has.. Happy flying!
I've been really struggling to get the compass reading properly in my OSD, it seems to bounce around pretty erratically. Great info here, hopefully will get me pointed the right direction.
For some reason Inav configurator won’t launch on my laptop, BUT luckily…. It’s all CLI commands so just did it with betaflight! I’ll test it tomorrow when it daytime 👍
mine worked fine like this tbh. just get a decent compass gps unit like matek m8q and just hit calibrate. set the orientation in the config mine is ccw 90 flip and you're good😊
You can do the same in Betaflight. I had to set it to CUSTOM for it to allow manual number entry. align_mag = CUSTOM mag_align_roll = -200 mag_align_pitch = 1800 mag_align_yaw = 2700
@@Painless360 It doesn't do navigation, other than GPS rescue, but I like to see where home is. And this setting seems to make the heading on the OSD a LOT more accurate. I have had problems with it so THANK YOU!
I found the explanation to this in RCgroups back in July when, like you, I'd spent hours fiddling and somehow got it working by trial and error. The acid test after all this is point drone North, East, South and West - does it display the correct headings? Then invert drone and test again, does it STILL display correct headings? If it does you got it right, if not start again 🤣
Yea been doing this. but my rekon7 has compass at cw180flip settings to work. at 270 its off by 90degrees. so on mine to add angle it is pitch 1500.. which is rekon hglrc default settings pitch = 1500 and yaw = 1800 in inav config. (though they still show config at cw270flip its just not used if manual values entered)
Thank you so much for this information! I'm building off the same frame. What are your thoughts about using 2604 1350kv for cruising on 1300-2200mah 4s packs and a Runcam 5 Orange? I'm trying to avoid purchasing $120 on the heavier, more demanding but popular 2806.5 standard.
@@Painless360 it flys! Really needed a lot more D and P. I'm using an old bn880 gps compass and still having issues getting it working. According to the documentation I can find it should be a 180flip for mine but that's not looking good either.
Hi Lee. I'm having a hard time with this because, in my case, I had to rotate the FC in 180º now, the instructions say the alignment has to be relative to the FC but does the values and alignment shown in the setup tab match the actual quad orientation or the FC? Thanks in advance
The only difference should be in the FC orientation settings in INAV. Once they are set then everything else is the same. This is why I always strongly suggest mounting the FC in the intended orientation, as it avoids all of these questions. Best of luck with it
I have attached an HMC5883 compass to my SpeedyBee F405 v3 flight controller, which is running the INAV7 firmware. The firmware successfully detected the compass. I calibrated the compass using the INAV7 configurator, simply by selecting the "calibrate compass" option and keeping the drone steady. However, I've noticed an issue: when I rotate the drone and observe the drone's depiction on the setup tab in INAV7, the image also rotates, but it does so at a significantly slower pace. It also takes a considerable amount of time to match the actual drone's changed heading. What could possibly be the issue here?
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 through JST Socket)
@@Painless360 because in Inav 7 configurator some of new updates.like alignment tool I was wondering may be u will post something regarding new version
Thanks for this one, as i have talking about re-positioning my gps mount off 20+ degrees. Do you think there is much more of an advantage for keeping satellites at 20+ degrees than degrees of 0 at horizontal with the quad?
It depends on how you will fly and where the gps is. An angle can help it point to the sky in forward flight but isn't as good if you regularly fly backwards..
thank you very much for covering this topic ! I also had been struggling for a week or so with the same problem in inav, and ended printing a flat gps support :-) Since I am converting to arducopter on a build with a tilt support, do you know if there is a special param for ardupilot ? or will the compass calibration do the job by itself ? thanks again !
Hmm... Pretty interesting indeed, Lee! Thanks! 😃 In the case of the GPS being flat, would it be the same without the roll part? Anyway, stay safe there with your family! 🖖😊
Hi master When I press inav rth, it wobbles when I come back, the electronic compass and compass are in the correct direction, and the adjustment is correct, what is the problem? #5inch #ArmattanDji
Is it just that the accelerometer in your FC was mounted at 90 degree about yaw and so the pitch axis became the roll axis? Also would be great to know if you set the mag align to 180 deg flip, does the direction of yaw become inverted (i.e. does a positive 20 deg yaw increment relative to the FC now become a negative 20 adjustment in the cli since, because the mag has been flipped about pitch, the positive direction of yaw relative to the mag is now negative)
@@Painless360 so, if inav reports the FC being pitched forward by a couple of degrees when the drone itself is on a flat surface, should we add those degrees of pitch to the mag alignment?
hmm i am rebuilding my glider with inav at the moment but i have no "flat space" to install the gps and compass unit. it will be always slightly tiltet in two directions .. does anyone have any data how precise it needs to be setup in the firmware? is +/- 10 degrees acceptable?
A compass isn't needed for an INAV fixed wing build unless you plan to fly in higher winds. As shown, compass alignment can be off level with the FC and set up easily. Best of luck
What am I doing wrong? I have a recon 7 pro. My gps is exactly same as in your video. I have tried all the options in Mag Alignment from default to cw 270 flip and still in the setup heading does not hold the position and when I try to tilt the drone it also rotates. I also tried your values in the CLI and it doesn't work either. Thank you
@@Painless360 mag_roll angle setting didn't work for me. is it possible that when I have default value CW270FLIP that mag_roll=0 mag_pitch=1550 mag_yaw=1800 works for my quad?
Surely that angled GPS/MAG mount is so that when the quad is in forward flight it becomes level, So can we not just, when rotating the quad during compass calibration, angle the quad so as to keep the GPS/MAG level ?
Try it. I did for 3 weeks. Lots about this didn't quite make senses. It seems to be the relationship of the compass to the FC you are setting up.. Happy flying!
I think the theory is that the quad tips forward ~20 degrees most of the time during flight making the module 'level' so it can see more of the sky and more sats.
could you just use the telemetry to tell you what the values are when its sitting flat? then you'd know exactly how much and where you need to apply it?
There are two schools in of thougt. It's easier to setup if it is flat but at an angle can point to the sky in forward.flight. Most compact quads mount at an angle.. Happy flying
@@Painless360 Thanks for the video. I’m not an INAV user and only tried it once and could not get the compass to work even with the fact that I had it mounted flat parallel to the FC. All that aside, based on what you found, I’m really surprised why the INA folks don’t have these settings setup as settings with a note as to which settings to change if your GPS/Compass is mounted different otherwise.

I was just about to type the same thing. Ha!
