Betaflight 4.3 Configuration Tab and GPS Tab | COMPLETE WALKTHROUGH PART 6

[@bkfpv]

No one does these kinda series better. Thank you Joshua.

[@andrewhull5095]

11:16 changing this saved me from losing my drone because my beeper wasn’t loud enough to hear where i lost it in the thick brush but it would spin and chop up leaves around it and that’s how i ended up finding it a few acres away🥳

[@Malzanar2010]

So I haven’t flown or touched my quads in over a year… man Betaflight has come a long way. Setup seems so much more intuitive and convenient than it used to be.

[@maryjane136]

One of my quads is equipped with a range laser which is supported by 4.3. I modified the BF source code to have a bar graph in OSD representing the height. I chase cars and for me it's very helpful to see where is my limit how low I can go because I don't want to read a numeric value all the time during the flight.

Thanks Josh! I just got back into flying and forgot everything about setting up the GPS... You saved me so much time :)

[@stephantertel]

I still learned something today. So setting camera angle mixes yaw and roll. I didn`t know that, will set it back to 0 and try to feel the difference .

So I wasn’t the only one pressing a motor to his ear and saying “no shit….”?

[@maloriezastrow971]

Just a quick tip for board and sensor alignment. Whichever axis is correct is the one that you need to put the correction angle on.

[@MrStreetboy80]

These are awesome series! Iv gone into fpv blind and had no idea about betaflight, so far Iv update firmware on a mobula6 that had mode 1 control setup and wouldn’t fly properly. So configured it from scratch, it fly’s pretty good now! I have another two drones with unknown esc and controller boards which need doing next.

[@quentincampbell5865]

33:50 The GPS icon at the top will only show when you have GPS lock. To see if your GPS is communicating properly (especially indoors), check the GPS tab. You should see some sort of activity there if it is communicating.

[@athenovae]

Also with Airmode and indoor flying, if you are close to anything your quad will get stuck from bumping into it all the time instead of letting you shimmy your way clear before take off.

[@andymattock397]

The GepRC Cinelog30 has an odd ball fc mount configuration, it's mounted inverted & at 45⁰. For the board and sensor alignment I set roll 0⁰...pitch 180⁰...yaw -45⁰. Fantastic set of videos

[@GifyTheOld]

0:50 I think you said small mistake there, because Accelerometer is for measuring how something is accelerating (how fast is moving) on certain axis in some unit per second, and gyroscope is used to tell, whitch direction is up (like artificial horizon in airplane)

[@dihler55]

I hope betaflight implements ublox7 at some point for GPSs since it allows for a higher update frequency on GPS modules that are ublox7 compatible (like the BN-880 which if you use Ublox7 on inav can update with a 10Hz rate).

[@XSPHEAR]

Have to say this series of videos has helped me understand more than i could have imagined using Betaflight so thanks JB for a great series .. amazing channel .!

[@AEMBowers]

I've got the weirdest situation going on. I just received an RTF quad from GetFPV. In the configurations tab on Betaflight (BF), it has the flight control (FC) set at 0 roll, 0 pitch, and 0 yaw. However, the gyro is set at CW 180. At the same time, I can see that the FC has physically been rotated 180 upon install (the arrow points toward the tail of the quad). Based on JB's instructions, the settings in BF's configuration tab should instead be: gyro set to 0 degrees, while the yaw for the flight controller is set to 180 degrees (I put -180, since I assume this corresponds to CW--it might matter for the math, as you'll see below). With either setup, physical movement of the quad matches that shown in Betaflight's Setup tab. This makes sense to me, and I will change it to how JB recommends. The issue is that I would now like to install a Matek M8Q-5883 GPS w/ compass. The manual for this GPS states that, if the arrow of the GPS points in the same direction as that of the flight controller, the Mag alignment in Betaflight's configuration tab should read CW 270 flip. For the best mounting and cable running for my GPS, I do in fact want the arrow on the GPS to face the same as that of the flight controller. However, the FC was mounted CW 180 as previously mentioned. So, do I need to input a mag alignment reading of CW 270 flip + CW 180 = CW 450 flip or, in other words, CW 90 flip? I realize that I can test this, but I won't have the ability to for a few weeks, and I'd simply like to know the theory in any case.

[@kd2rdhlarry571]

Well Done, very well done.

[@Deserthacker]

Maybe inflight accelerometer calibration could be (ab)used to keep the quad tilted forward and use it as a cruise control for level mode? Seems like a fun thing to try out.

[@___fernando]

Hi there. I'm building my first FPV drone, TYRO79(Matek F411) and I’m doing some improvements, for now, I would like to get a GPS on it. I read some articles that some people got success doing it when creating a softserial and using the led_strip pad (Pin A08) to do that as a serial_rx 11 A08 and the serial_tx 11 A02. I activated everything on betaflight (feature GPS), on ports, enabled the GPS, and on configuration enabled the GPS too. But, I didn't get it recognized on FC (betaflight). I also connected the BN-220 directly on my computer, just to confirm that it's working and it is. So, the gps unit is not the problem. I powered the gps unit on a external power supply at 5v to confirm that there's no issue with the power supply from the fc. I also tried to connect the gps unit directly on the UARTs 1 and 2, but no success. I am connecting the GPS TX pin to the FC RX pin port and the GPS RX pin to the FC TX pin port as mentioned above. It's right, correct? I'm not comfortable to invert it. I also tried different firmware versions, but no success. The last one available for this FC is the 4.2.11. Can you help me ? Thanks

[@Idontdohandles]

On the GPS topic - having a hellish time getting a GPS going on a board I pulled from the Crux3.5. I put a Beitian 220 on UART1 - rx1/tx1 --- and when i set it up for GPS as instructed -- I am not getting the yellow confirmation "GPS" indicator in Betaflight that FC and GPS are communicating, of course, no fix either. I've tried everything - a different GPS - Beitian 180, swapping out Rx and Tx wires just in case I have them backwards - power lights are coming on for the GPS unit, FC is otherwise BRAND NEW and in perfect working condition. BAUD rate i set auto and manual --- auto its jumping to 57k on its own. Now stumped. :( Something up with UART1 not able to be GPS --- this is an ELRS SPI Antenna on the board -- does that maybe mean UART 1 is not available if i'm using the SPI antenna -- wouldn't make any sense though. Grrr its 4am and still trying at it.

[@luvmyhondasi]

Thanks again

[@guytas]

ok, 4 months later, I have another question on compass. I have installed the GPS with magnetometer. I also adjusted the declination related to where I live. Now the compass on the betaflight screen shows pretty much the right direction. But the thing that bugs me is if I rotate the quad on my desk, I see the compass moving along with the rotation. But when I stop rotating, I see the compass readjusting itself more or less depending on how many degrees I rotated. For instance, when I rotate to about 90 degree, the compass re-adjust to about 2 more (or less) degrees. It's almost like if the gyros degrees are not the same width as the mag degrees. It's weird.

[@DieCurrywurst]

[@turionb1408]

[@Fly_High_FPV]

Are you sure the FPV camera angle changes flight characteristics? I just tested at 45 degrees and 0 degrees, I hover the quad in acro and do a yaw spin, both spin perfectly flat. I really dont think this changes anything in flight. Happy to be proven wrong

[@JoshuaBardwell]

If you are hovering, then no, the camera angle has no effect, except that with higher uptilt you're looking at the sky. The difference comes when you are in forward flight, and you have leveled the horizon in your goggles. With higher uptilt, you are pitched forward more, so the mix of roll and yaw required to turn is different.

[@Fly_High_FPV]

@Joshua Bardwell i understand crosscoordinating turns and how camera tilt effects that in flight. I'm just not convinced that setting the FPV cam angle in BF has any impact on flight dynamics, are you certain it does?

[@Fly_High_FPV]

Ok, so BF does have compensation, but it's dynamic and varies based on how close you are to the set pitch angle 👍

[@FluffRat]

I thought all it did was offset the horizon line in the OSD? I've been using it like that never even thinking it might change flight characteristics and haven't noticed any weird yaw/roll shenanigans at all.

[@Fly_High_FPV]

@FluffRat it does change flight characteristics, closer to the tilt angle, the more it compensates

[@antonixalkou3738]

JB I LOVE YOU

[@carlonchino]

Muchas gracias por la explicación me sirve de mucho

[@guytas]

At the beginning of this video you show how moving the gyros moves the quad on the screen. I can see on your screen, that the compass in the INSTRUMENTS panel moves too. But how do you set this compass north? For me, the north is always where the quad was pointing at power on. Sounds strange. But my main concern is this: will this affect the return to home feature if I powered it on facing other direction?

[@JoshuaBardwell]

That's because you don't have a compass. So the quad just guesses that north is where you were facing when you powered up. No, it won't affect return to home. The FC knows that isn't really where north is.

[@chriskasten376]

@@JoshuaBardwellSo in theory, if I set my quad due north when arming, my goggles should show approximately the correct heading?

[@danield.8615]

Very good tutorial! Thanks a lot for this update.

[@fayazmd83]

Thank you so much Joshua for making highly informative videos! I upgraded my Trashcan from BF 4.1.0 to 4.3.0. I noticed that actually some PID controller settings are changed after the upgrade. for eg. feed forward, dynamic damping etc. I restored them to original settings. As you mentioned that after you import the preset (saved file from earlier firmware) into the newly flashed firwmare, all factory settings should be applied/restored. I performed this step as well. Everytime I fly the quad after a few seconds of flight, the motors get disarmed. Can you please suggest what might have gone wrong?

[@1870movie]

I feel you need to understand Airmode in BF 4.3 has a very bad user experience for some people. For some of us (not all and I do not know what only some), Airmode causes a runaway that is not detected by runaway detection (very bad). When Airmode is enabled and the quad is armed, the motors spin as expected. Once the throttle is raised, then immediately a runaway occurs. People with this problem find switching back to BF 4.2 resolves the problem. I have been pulling my hair out trying to understand why and this is what I found. I found the problem can be resolved with two options: 1) disable Airmode and enable motor stop (not desirable) 2) disable Airmode and set Dynamic Idle Value (found in PID Tuning) to 3000 to 4000 RPM as recommended in the BF Wiki This problem is present any time Airmode is enabled even with Dynamic Idle enabled or disabled. According to the BF Wiki, dynamic idle has been rewritten in BF 4.3. I assume the BF developers are not aware of this runaway problem as a result of rewriting dynamic idle. Maybe you can help raise awareness of this safety problem. Here is an example of the problem. This does not seem as severe as a runaway like I am experiencing, but this looks to be the same problem. github.com/betaflight/betaflight/issues/11655 By the way... Thank you for your excellent service to this sport!!!

[@JoshuaBardwell]

If airmode causes a flyaway, there is some other mechanical problem with the quad. The gyro should not get enough feedback to cause flyaway even with airmode enabled. Turning off airmode obscures the problem, but it's like putting a splint on a broken ankle. You might still limp on it, but it's not fixed. This isn't a betaflight bug. It's damaged hardware or improper building methods (no disrespect intended to the builder).

[@1870movie]

@@JoshuaBardwell Thank you for the feedback. I am surprised the problem is with the quad since the quad flies great with Airmode turned off. The flight controller is new. Should I use rubber mounts?

[@Flyit37075]

is it possible to physically disconnect the GPS wire harness in the field or a building if Im having trouble , or Is it possible to put an in line switch in the GPS wire harness , would the quad operate at all ?

[@joecachia2]

Hi Joshua, Great work as always. So helpful. Small question from a newbie. I ordered a tyro79 rtf kit , as my first beginner quad. Now I have no idea what Betaflight version it comes with . but I am assuming that if i had to flash the firmware to 4.3 , I would loose all the settings it currently has right ? Would flashing to 4.3 , still have some default values and keep the quad operable or would most stuff have to be manually set ? Would it make sense for me to take screen shots of all Betaflight tabs , so that I have a ref of what settings there were ( apart from taking the CLI backup of course ) ? I also plan to take note of the original Betaflight ver it has so I can revert back to it along with the CLI backup.

[@JoshuaBardwell]

Please start at part 1 of this series where I show how to back up settings before flashing. That will ensure you can go forward without losing the old config if you want to go back. You will lose all the manufacturer settings but you can use this safe migration tool to bring many of them forward. bf43-safe-migration.robertodedomenico.it/

[@Sleeperknot]

Hi Joshua, Thank you for your videos! I have a question: I have connected a Ublox Neo 6M GPS module to my quadcopter, which is based on the Speedybee F405 v3 and running Betaflight 4.4.3. In the Betaflight configurator, I can see that I have a 3D GPS fix, and when I issue the "gpspassthrough" command, I can see data being written to the CLI. However, I've noticed that the GPS icon in Betaflight does not turn yellow. I have connected the GPS module to UART6, disabled auto baud (although I have also tried enabling it), enabled auto configuration, and set the baud rate to 115200. I'm wondering why the GPS icon is not turning yellow. Should I be concerned about this issue, or can I just ignore it? It's worth noting that even with this issue, the quadcopter arms with Return to Home (RTH) configured, which is set to disable arming without a 3D fix.

Make sure the motor is spinning the right direction, when looked down from the top. Install props the right way up, when looked down from the top (so, upside down relative to the motors).

[@ls4life544]

Great video! question if someone could answer it. What would be the negative effect of making the board alignment fix using first gyro? I have fixed the issue of not facing the direction I moved the quad using the option "first Gyro," and it still flights as I think it should be based on my base judgment.

[@JoshuaBardwell]

There is no disadvantage, as long as you get the alignment right. But since boards don't always default to 0 degrees rotation as default, setting that value can be unintuitive.

If you're on a firmware so old that it's even possible to un-sync the PID from the gyro, then I wouldn't use it. Update the firmware to something newer and/or skip that FC and get something newer.

Quad arms as usual, no funny noises and when you want to takeoff quad goes like 5cm in the air and just wont go higher, even if I put 100% throttle it will just hover 5cm from the ground.
