Definitely not a hobby for those who don't want to invest in learning a new OS/System. From troubleshooting Betaflight to figuring out what the menu's on the controllers do. Many variables. It is rewarding if you stick with it though!
The way I tested the failsafe is Land over 200m away and then turning off the remote. If it works the quad will take off and come back. If it stays it won’t work. Just in case you don’t want to crash your stuff 😉
keep it armed. You can turn off air mode and/or idle prop spin so it does not freak out on the ground. Betaflight does not detect if you are flying or on the ground so as long as it’s armed it thinks you are flying and starts the return to home if the remote is turned off.
Niiiiiiiiice... He didn't mension your name!!?? You fixed his life-long frustration!! He should send you his quad as a "Thank You"... 😂😂 Just kidding 😘😘
@@stickboyfpv4742 CUT must be set in the module so when you failsafe the receiver stops sending pulses/commands to the flight controller and then the flight controller is able to trigger whatever failsafe method you configured in the GUI (drop, gps rescue, etc)
Glad you stuck with this project cause I get the feeling that with some of the tips you showed in here, my GPS Rescue issues will be gone when I hit the sticks tomorrow. Thanks for the trial and error work brother.
Great stuff Paul! Your persistence pays off! Thank the dev's for GPS rescue, its awesome! Found a few ways to get around any electrical "noise" that slows down your GPS module getting a "fix."
My daughter went to that school! You could see my old neighborhood from your drone! Know the area well and have had many DJI Mavic flights. Keep up the good work!
Funny how there’s many ways to achieve the same result. I used crossfire Fs.pos to trigger rescue mode by setting the switches in armed and rescue position when setting FS.pos on crossfire. This bypasses the Betaflight failsafe protocol and goes directly to rescue. It seemed like there was less delay and reconnect time when testing by turning off the radio. I’ll try it your way on my next quad soon and see what the difference is. Thanks for sticking with it.
YESS THANKS SO MUCH FOR MAKING THIS. super in depth, nice to see you show your failures and successes like you did. I am about to start my first long range build, first 7 inch build, first crossfire build, annnnd itll be my first ever 5s set up as well. Excited af to be building quads again. i haven't flown in months 0.0
I have been struggling with this same issue over the past months. The feeling you showed when something finally, FINALLY worked the way you wanted it to will hopefully be the same feeling I will be having soon. Thanks for sharing your struggles and success, it helps me out immensly. Stay safe and healthy
One more thing about your settings: the altitude setting is a bit tricky as well. It goes the value that you've set *plus* the highest you were during the flight. That is so that if you have flown over something that's higher than your altitude setting it will go over it.
@@jhonnycasshh yes, if you lose signal and the quad starts to come back you'll have some delay when it reconnects again, just stay cool and move the pitch and roll slightly till you see it responds to the inputs.
Channel fallback values are done after a failsafe has already been detected. So when you set failsafe mode (stage 2, receiver signal loss) from drop to gps rescue there is no need to set the AUX channel to FS also.Your main problem was Crossfire not triggering stage 2 failsafe at all. There is also a "Set Home Point Once" option under GPS settings. If you activate this it will only set the GPS Home point the first time you arm, meaning you can disarm/arm during flight and not change the home point to something else.
those are great drones. I'm an old fart myself. After flying my son's Holy stone I was hooked. Now have a Tiny Hawk 2 amd an Armattan Marmotte 5" and now doing a 5" Catylst Machine Works build myself.
This is so satisfying. The challenge of FPV is awesome in every level, even troubleshooting, followed by sweet victory and that feeling of excitement when you finally figure out the problem. ❤️🙌🏽⚡
Cheers for this man! I have set rescue up ages ago on an old quad and forgot how to get it set up so this was decent way to recap and just entertaining man! Away to go out and test now as heading across to the Isle of Skye in a few weeks and going to do some proper mountain surfing so wish me luck haha
sorry so late to the video, just going thru the same issues, glad to see it working and really appreciate you troubleshooting this on video. I had a feeling it was a crossfire issue since mine works fine on a RXSR and even a xm+ but on crossfire it only worked in rescue mode. Thank you so much will try this out tomorrow after work, weather permitting. I thought I was going to have to be quick enough to switch to rescue mode before I lost complete control, (not exactly what I was wanting), my panic mode is a little to slow.
So glad you got that sorted out. I was scared after watching your video that my failsafe wasn't properly working, but I have r9 on my GPS quad, and the few times I tested failsafe it did work. Never shut off my radio though lol. Good to know all this today, because today's the day it moves to crossfire!
That is a great idea to fly 200m away and land, stay armed and test gps rescue. I tested my GPS rescue by arming the quad (removed props) and putting it on the dash of my car while I drove 200m away with the controller and flipped the switch. The motors spooled up and in my fpv goggles I could see the arrow pointing to where I drove from indicating things should work. I then did this same thing to test turning off the controller. Same thing success. So this gave me the confidence to try the failsafe in real conditions and so it worked.
I always thought it was so strange that the GPS rescue mode was a big mystery with no definitive instructions, at least that I could find. Almost as if BetaFlight was found in a cave from a long lost civilization. Betaflight has developers, right? Why has this been a mystery for so long?
A very useful tipp. Set your homepoint to the location where the quad is going to power up. So if you disarm and arm again while flying, the home position is still at the point where you plugged in the battery. if you unplug and plug the battery back in, then there is going to be a new home position set.
I think the "Channel Fallback Settings" take effect in Stage 1, not in Stage 2. So the quad doesn't set the aux 4 to 1800 after 0.2 seconds (in your case); it just sets it to 1800 instantly. It's annoying to have it set this way and you have microfailsafes on the drone because the gps rescue will kick in right away. If anyone knows something different, please answer :)
Please let us know in a follow up if you end up changing sanity checks back to failsafe. I'm going by your settings getting ready to fly and test gps for my first time.. 😮 Lol Ive had this for about 5 months now but I have waited and waited for a video like this to come out! Thanks for all the detail!!!!
Awesome! I'm halfway through my 8in qav-rxl build. And I can't wait to hopefully have the same success with gps rescue. Although I'll have an R9 handycap. But I have actually been lucky with its capabilities so far. But I am still definitely going to crossfire sooner than later! I need some TBS TRAPPY SECURRITY IN MY LIFE FOR THE REAL!
Surprised u had issues. Bardwell vid from last year worked first try. Glad it works. Make sure you’re far out enough. You can set less distance out too.
Try to set ur gps ground assistant type from autodetect to ur region. I guess that prevents u from those sattelite drops during flight. Also disable the autobaud rate and set it to 11xxxx.
Great stuff man, glad I know about the crossfire settings before I try this myself, thanks. BTW when you were flicking the switches coming out off failsafe I had already read somewhere that you get control back when you put in a stick command and I was almost shouting at my screen the first time lol 😂😂😂 and I know turning the radio off is something you really need to do a few times to start to trust it but man that’s terrifying. Thanks again for uploading these videos, they help a lot 👍😎
Hi Nurk i forgot to mention that point, but you can do either way , if you let Xfire in "FSPOS" you will have to program the Aux channel "gps rescue" in the correct position in your radio/RX this time, i don't remember the exact process you can do this way too. But the best way is to select like you did "CUT" and set in BF the failsafe gps rescue AUX chan with the good value 1800 in your case. when i had this issue my Xfire was set correctly to "cut" but the gps Rescue aux chan in BF was set to hold...and my Kwad tumbled down each time i switched off my radio. By using only the gps rescue switch it worked like a charme !. it is not obvious , 1st you have to declare an AUX chan for gps rescue, and then you have to tell BF that you did so, it took me a while to understand what was the problem. Sry for my really basic English :) Nice Channel Happy Flying cheers ! Phil
failsafe set isn't necessary; in addition, stage one functions are what you'd want to set for failsafes; set throttle to a level that allows it to climb, set flight mode to level stabilized mode instead of acro or whatever. This'll stop the quad from being in a real weird unexpected position or very aggressive angle, and then it'll be in a safe spot when stage 2 kicks in.
You still don't need it to set to return to home. If you have stage 2 set to GPS rescue, then it will GPS rescue. Previously it must have just been the crossfire sending a disarm signal that was the problem. Also, you can change all your GPS rescue parameters in the OSD now.
I followed the instructions under Oscar Liang and also set the Crossfire failsafe to CUT. Worked like a charm the very first time I tried it. Thanks lots!
Hey Nurk FPV! Awesome video. You said you added a fail-safe switch at 14:20. What is a fail-safe switch? Is this similar to the switch that we use to trigger GPS rescue?
So I took a break from the quad world. What happened to iflight?? I wanted to do a build that had a position hold function and iflight was the only option. It looked decent from the few vids that were posted. Flip a switch, freestyle, flip another, position hold. Would even return to home and land nicely.
did you ever figure out what happend at 8:00? I keep getting those same results every 2-3 attempt at tesing gps rescue. ATM I have 0 confidence that this will bring my quad back home... when I flight the gps rescue switch the quad shoots up into the air (over 200m, even though my rth height is set to 30m) and it does not come home... even though my distance to home indicator does show the distance from home point correctly.
Note for RR:…don’t have failsafe as a switch. This for testing only, and may result in a false sense of security being that the test is in controlled conditions. Instead, being that we are more likely to lose video b4 rx, have gps rescue mode as a switch. In this way, if we lose video, trigger gps rescue. When vid is restored, resume control via stick command input.
Hi Nurk, I like you OSD setup.Can you explain to me how to get the altitude bars showing on the right hand side? and what are the multiple bars showing on the left hand side? what do I have to enable in the OSD to see the commands like in yours? thanks so much!
The only thing that still has me puzzled is the channel settings for stage-1 failsafe... If I had the quad connected w/o power to the receiver it would say in BF "GPS rescue switch in an unsafe position"... So *if* you're using GPS rescue on a switch (in addition to failsafe) the value for stage 1 needs to be at the value where it would be activated on a switch. ... ?! ;D
Just had a thought.......it would be great if betaflight was able to detect the bitrate of the dji system so that for example if the bit rate hits 0 mbps for more than a pre set time then the gps failsafe would kick in. So a failsafe for Rx loss and also video loss!
Nurk this is a cracking video and so helpful. So just to check - I have GPS bailout set for my failsafe and changed the delay to 2. I have NOT set a failsafe switch & have crossfire (on jumper t16 lua script) set to cut. Anything else ? Thanks man 👍👍
I'm at 7:40 and recall seeing a green ring on the xfire module during the first test - radio off, xfire still connected to rx = no failsafe, just no control = no gps rth?
You can use "set gps_set_home_point_once = on" to make sure that it only sets your home point the first time you arm after connecting a battery, so disarming and re-arming mid-flight won't mess up your home location.
what about your modes tab? do you have crossfire set up as 8ch? will you post your modes tab so we can see your switches. thx Nurk. I have been tuning my 10" and am ready to apply some GPS rescue. Thanks a million for this video
It's the same thing for inav with csrf. The only time you want pos hold is with a fixed wing with no fc or with zohd ko -piolet with the rth switch enabled when you record the fs position
@@NURKFPV I wouldn't mind seeing documentation from betaflight about this essential step when setting up a GPS failsafe. I can only imagine how many people lost quads thinking they had some kind of insurance
Hi there, i am planning to put the BN880 to my Protek 35 FPV. But I realized the FC (Beast F7 55A V2.2 AIO (BMI270) 25.5x25.5) does not have the SDA & SCL slot. I wonder where should the SDA and SCL wire on the BN880 be soldered on? I plan to use the BN880 instead of the BN220 because I want the compass function as I keep getting lost in the forest...
Man I live a few miles west of Indy. We should fly together sometime. Lol I could never get my bn-220 to work. Just drops out of the sky. I set all the things in betaflight correctly I think. Sanity was off too
If you could fly low at a distance, you could just land your quad at that distance, keep it armed and shut down your radio. If it works, it'll fly up and get back to home, if it doesn't work, it'll just disarm on the ground. which eliminates chances of any hard crashes. Another thing, don't ever set the failsafe switch to be in failsafe when it failsafe in the failsafe tab cause that will make you unable to get out of failsafe mode when you ever failsafe if that makes sense.
Just build a tbs discovery. Was hoping for this to work but will switch to inav. First all cuts when enabling GPS rescue. (ground test) Switched to sanity checks failsafe to get that work. Did a ground test by moving the quad 200m from home but didn't trust it. Turning of transmitter same issue as you. So already was thinking about tuning off crossfire failsafe. Decided to build a scratch 5" quad with same controller to test. Don't want to wreck my Discovery. Hope your video will help. Looks promising. Thanks. Btw my home arrow doesn't work properly. Any tips? Just re-upload another font. Not tested yet. How do you get the H (home) sign in your OSD. BetaFlight 4.2.2
The "Position" mode for Crossfire can still be used to activate fail safe correctly. Just set up your toggle switch for GPS Test mode on the radio and in BF. Then toggle the switch into the GPS Test position. Then set the failsafe positions via the Crossfire menu. At this point if the radio link is severed, the Rx will automatically enable the channel for GPS Test and BF will then enter GPS Test mode. *** THE BEST WAY TO TEST THIS IS ON THE BENCH! *** Plug everything in and run BF Configurator. Go to the Receiver tab and then turn off the Tx. Then watch the channel that activates GPS Test. It should move the channel value into the region you have set for GPS Test mode to be activated.
Thanks! You can also test everything IRL easier, just remove props then plug the battery (outside), wait for 7 sats then put your drone and transmitter on the car, arm, drive 300m and turn off transmitter. If your motors go full then it works, if it just disarm then it doesn't
@@jordigrau83 Interesting test idea! BTW, you should also make sure the quad is in armed mode when setting fail safe positions on crossfire. Not sure what happens if it gets a GPS Test signal but the quad is not armed. Maybe that's why Nurk was having problems using that mode. So... on the bench with everything powered up (props off!), arm the quad and enable GPS Test mode. Then set fail safe positions. Test it before flying long range though!!!
Hey!! Grest video! Can u answer me a question? When you turn off the radio and the back on your arm switch remain on arm position? You don't have to touch It, right?
I'm sitting here wondering if you ever checked what the channels go to when you power your radio off while in the mode config menu. Mine instantly disarm since that channel toggles from 1800 to 1100 when the link is lost. I'm feeling if 'FS Pos' is setup right, it would still work while 'FS Cut' just rules out that configuration aspect.
Yeah it really depends on a bunch of settings, but in particular, I just needed FS CUT to just drop everything back to the base level so that it would just go ahead and hit those failsafe modes.
@@timcable iNav is from the same code base. If you can use Betaflight, then you'll have no problem with iNav. The differences are in the minor features - such as GPS.

You land and keep it armed? Or disarm?
Lmao this is a way smarter way, then I suppose if this works then you can test it in air to make doubly sure.
keep it armed. You can turn off air mode and/or idle prop spin so it does not freak out on the ground. Betaflight does not detect if you are flying or on the ground so as long as it’s armed it thinks you are flying and starts the return to home if the remote is turned off.

You can change the 30% setting in CLI, to something more or less

ATM I have 0 confidence that this will bring my quad back home... when I flight the gps rescue switch the quad shoots up into the air (over 200m, even though my rth height is set to 30m) and it does not come home... even though my distance to home indicator does show the distance from home point correctly.
Why doesn't the parachute icon work in Betaflight to kind of give you that warm & fuzzy that your your FC knows to RTH when the radio is off?
What happens if your radio actually fails and you can’t get it back on? Will the drone continue to hover above until it kills the battery?
A tutorial for this would be really good, not many are going to be as technical as you and / or have the time or patience to pull this off.
great video but would have been good to also show the modes tab because i'm not sure when you set 1800 if the quad should continue armed or not.
Nice work bud.. I'm just about to do a build like this and this video will definitely come in handy
Yes you have a little bit more confidence with going far !! Thank you for your video :)
well done. Hey Nurk, can you tackle the same, using all your DJI digital set-up?
Anything changed with new stuff these days?
Do you use gps on gigs and cine rigs?
Glad you got it working. Nice work!
Thanks man! Really glad that it's finally there.
Note for RR:…don’t have failsafe as a switch. This for testing only, and may result in a false sense of security being that the test is in controlled conditions. Instead, being that we are more likely to lose video b4 rx, have gps rescue mode as a switch. In this way, if we lose video, trigger gps rescue. When vid is restored, resume control via stick command input.
Nice Haircut about time 👍🏻 Thanks for all work that you put into test
Awesome, glad you got it figured out!
Hi Nurk, I like you OSD setup.Can you explain to me how to get the altitude bars showing on the right hand side? and what are the multiple bars showing on the left hand side? what do I have to enable in the OSD to see the commands like in yours? thanks so much!
How to setup these nice sidebars for altitude and speed? I cant find these on the OSD page of Betaflight 4.28... Thanks.
It's part of the brainfpv stack
@@NURKFPV Nice, thank you
The only thing that still has me puzzled is the channel settings for stage-1 failsafe...
If I had the quad connected w/o power to the receiver it would say in BF "GPS rescue switch in an unsafe position"...
So *if* you're using GPS rescue on a switch (in addition to failsafe) the value for stage 1 needs to be at the value where it would be activated on a switch. ... ?! ;D
Just had a thought.......it would be great if betaflight was able to detect the bitrate of the dji system so that for example if the bit rate hits 0 mbps for more than a pre set time then the gps failsafe would kick in.
So a failsafe for Rx loss and also video loss!
Nurk this is a cracking video and so helpful. So just to check - I have GPS bailout set for my failsafe and changed the delay to 2. I have NOT set a failsafe switch & have crossfire (on jumper t16 lua script) set to cut. Anything else ? Thanks man 👍👍
I'm at 7:40 and recall seeing a green ring on the xfire module during the first test - radio off, xfire still connected to rx = no failsafe, just no control = no gps rth?
saved me some hours of work man, thanks a bunch!
My pleasure!
You can use "set gps_set_home_point_once = on" to make sure that it only sets your home point the first time you arm after connecting a battery, so disarming and re-arming mid-flight won't mess up your home location.
Gonna set that right now.

what about your modes tab? do you have crossfire set up as 8ch? will you post your modes tab so we can see your switches. thx Nurk. I have been tuning my 10" and am ready to apply some GPS rescue. Thanks a million for this video
That tree just jumped out in front of you. LOL Good stuff
Yesss good job, now how about r9m module on taranis xlite which.. don't have that "cut " option haha
Set it to no pulses
@@ScrapHeapFPV but how, there is no display on it. It's the lite module
It's the same thing for inav with csrf. The only time you want pos hold is with a fixed wing with no fc or with zohd ko -piolet with the rth switch enabled when you record the fs position
copy that
@@NURKFPV I wouldn't mind seeing documentation from betaflight about this essential step when setting up a GPS failsafe. I can only imagine how many people lost quads thinking they had some kind of insurance
Just in case you haven't heard in bf4.2 there's an option to keep the home point after disarming ( Will only be reset after power cycling the qaud)
NURK,,, why are you not using your DJI fpv system and doing this they have the firmware download for GPS rescue
Every time I watch you I send more $$$ I have to have a 399 Super G now. Congrats on getting it going!
Hi there, i am planning to put the BN880 to my Protek 35 FPV. But I realized the FC (Beast F7 55A V2.2 AIO (BMI270) 25.5x25.5) does not have the SDA & SCL slot. I wonder where should the SDA and SCL wire on the BN880 be soldered on?
I plan to use the BN880 instead of the BN220 because I want the compass function as I keep getting lost in the forest...
I got super confused when you said the same thing twice back to back. I had to go back 30 seconds to make sure I wasn’t going insane. At 14:20 😆
Man I live a few miles west of Indy. We should fly together sometime. Lol I could never get my bn-220 to work. Just drops out of the sky. I set all the things in betaflight correctly I think. Sanity was off too
if you use the fail safe on a switch. And you re arm it sets a new home position and the distance is set from there
Also very helpful! Thanks for sharing!
If you could fly low at a distance, you could just land your quad at that distance, keep it armed and shut down your radio. If it works, it'll fly up and get back to home, if it doesn't work, it'll just disarm on the ground. which eliminates chances of any hard crashes. Another thing, don't ever set the failsafe switch to be in failsafe when it failsafe in the failsafe tab cause that will make you unable to get out of failsafe mode when you ever failsafe if that makes sense.
Just build a tbs discovery.
Was hoping for this to work but will switch to inav.
First all cuts when enabling GPS rescue. (ground test)
Switched to sanity checks failsafe to get that work.
Did a ground test by moving the quad 200m from home but didn't trust it. Turning of transmitter same issue as you.
So already was thinking about tuning off crossfire failsafe.
Decided to build a scratch 5" quad with same controller to test.
Don't want to wreck my Discovery.
Hope your video will help.
Looks promising.
Thanks.
Btw my home arrow doesn't work properly.
Any tips?
Just re-upload another font. Not tested yet.
How do you get the H (home) sign in your OSD.
BetaFlight 4.2.2
What patch antenna do you use on your goggles?

The "Position" mode for Crossfire can still be used to activate fail safe correctly. Just set up your toggle switch for GPS Test mode on the radio and in BF. Then toggle the switch into the GPS Test position. Then set the failsafe positions via the Crossfire menu. At this point if the radio link is severed, the Rx will automatically enable the channel for GPS Test and BF will then enter GPS Test mode. *** THE BEST WAY TO TEST THIS IS ON THE BENCH! *** Plug everything in and run BF Configurator. Go to the Receiver tab and then turn off the Tx. Then watch the channel that activates GPS Test. It should move the channel value into the region you have set for GPS Test mode to be activated.
Thanks! You can also test everything IRL easier, just remove props then plug the battery (outside), wait for 7 sats then put your drone and transmitter on the car, arm, drive 300m and turn off transmitter. If your motors go full then it works, if it just disarm then it doesn't
@@jordigrau83 Interesting test idea!
BTW, you should also make sure the quad is in armed mode when setting fail safe positions on crossfire. Not sure what happens if it gets a GPS Test signal but the quad is not armed. Maybe that's why Nurk was having problems using that mode. So... on the bench with everything powered up (props off!), arm the quad and enable GPS Test mode. Then set fail safe positions. Test it before flying long range though!!!
for us with express elrs we cant set no pulse? i am struggling with this drone just disarm like you did , rth did work but not when i remove module
Hey!! Grest video! Can u answer me a question? When you turn off the radio and the back on your arm switch remain on arm position? You don't have to touch It, right?
I'm sitting here wondering if you ever checked what the channels go to when you power your radio off while in the mode config menu. Mine instantly disarm since that channel toggles from 1800 to 1100 when the link is lost. I'm feeling if 'FS Pos' is setup right, it would still work while 'FS Cut' just rules out that configuration aspect.
Yeah it really depends on a bunch of settings, but in particular, I just needed FS CUT to just drop everything back to the base level so that it would just go ahead and hit those failsafe modes.
Hey, good work sticking with it until you got it to work!
You got it working! Nice job. Maybe you could try using GPS on an iNav flight controller - that would let you fly waypoints.
can one mix betaflight and inav? or do I have to choose only one of those two? May be a silly question for experienced, but I'm a noobie, ok.
@@timcable iNav is from the same code base. If you can use Betaflight, then you'll have no problem with iNav. The differences are in the minor features - such as GPS.
Hey Nurk, this is incredible! Can you also do this with the DJI FPV HD modules?
yes
