M10 gps and Betaflight 4.5 are really amazing. @12:10 The faster GPS baud is CPU intensive. It's advised to use 57600 baud AND 4k pidloop (even for F7) per the "Betaflight 4.5 GPS Rescue" docs. If you want 8k8k then you have to use 2Hz which is 19200 baud. Great how-to.
@@soar_fpv there is some kind of issue that hasn't been figured out yet, dshot300 seems to solve some of these. Regardless, 57600 baud is advised and sufficient for 10hz updates (which gives stable rescue mode flight)
Thanks for the setup explanation. With the GPS, HDOP is "horizontal dissolution of position" . It shows how much you are drifting horizontally. Less is better. Roughly speaking a 1.6 HDOP means your quad will hover 'in place' within a 1.6m horizontal square.
If you connect the GPS to a USB powered pad, it will sometimes interfere with BetaFlight firmware flashing. The iFlight F7s have this issue and it’s happened to me on IARTs I’ve been told it should be an issue on. It definitely happens on the one recxomended for GPS. Crossfire also has this issue. What has worked better for me is to use a flight controller with a built in put switch and use that to turn off the VTX for the first flight of the day until I get a fix. Your flight controller has this and also does not power the GPS from USB. This is much easier to deal with than plugging in USB for the first GPS fix.
About Galileo: It's the satellite navigation system of Europe. GPS is American made, then there is GLONASS (Russian) and BeiDou (Chinese). GPS, GLONASS, BeiDou and Galileo are the biggest/most well developed systems. General term for these is GNSS. Most GNSS receivers can work with three systems simultaneously.
As for the ground assistance, in north america it's safe to set it to WAAS because that's the only one available here. I highly highly suggest anyone using gps to have WAAS (or your local equivalent) enabled, because it takes the normal gps accuracy of 50 feet or so, and turns it into ~3 foot accurate with basically no downside. It's the same technology full scale aircraft use all the time to navigate to runways even in poor weather conditions.
Thats because H is horizontal which isnt correct. You want P for Postion. For the record 1 to 2 is excellent precision, 3 to 5 moderate and 6 and above is not good.
I don't know what you did for a living before you started RUclips Joshua but you awesome teacher lolthank you for posting all these wonderful how to vids
You said the simplest thing, and it made it dawn on me, about putting the GPS on a USB 5 volt rail, especially when using HD. Never even thought to just plug into it at the field, and let that "warm" the GPS up, so the VTX is not running and over heating. I learned something today!!!
Some words on the CLI parameters GPS_RESCUE_VELOCITY_[PID] and GPS_RESCUE_VELOCITY_[PID] would have been good. They make all the difference of either letting you sit back and enjoy the auto-return or, when set incorrectly, giving you a heart-attack. Any pitch-jerking on return or throttle oscillations on the descent can be tuned away.
I’ve been using Vifly gpsmate on a few quads that I have gps on. Self powered and it works on getting sats locked without plugging in and not having to use usb. If you have room for it they’re great. Also works as a self powered beeper if you crash and eject your main battery.
Galileo is a constellation of satellites (European) same as Gps(American), Glonass (Russian) Beidu etc… SBAS stands for Satelite based augmentation system, based on ground stations giving possible corrections to certain satellites being off time, transmitting it to a ref satellite (Wass is PN the Us, Egnos in Europe or Gagan India, etc..) to compute the correction signals, the SBAS geostationary satellites communicate with regional ground stations and this leads your system to use more satellites even if they are not perfectly synchronised : more satellites being used leads to a better position precision less than 2 meters in my case !
I know we’ve come a long way in the FPV hobby and I appreciate all the things the devs do, given that this is a volunteer open source project. But I’m still surprised it’s this complicated to make return to home function, sort of. Also, the heading arrow should really just be taken out. If it doesn’t work reliably most of the time then it’s really a hindrance. I nearly lost a drone by relying on. My bad I know. Issues aside, I appreciate where we are and I love this hobby! Keep flying kids.
Or maybe try INAV. Also flies great Acro, and will raise to a preset altitude to clear the highest obstacles before making a beautiful landing at the takeoff point or a safer preset home point.But...good progress BF. Looks very useful.
BF will either raise to preset altitude OR a preset height ABOVE the highest altitude you have flown during that flight. Also, it lands perfectly smooth touchdown, I was impressed that one one landing one prop just tiny touched a leaf on a bush.... it immediately disarmed and dropped the remaining 2ft
We fly betaflight for the quad performance, not for missions or cruise mode, rth is for emergencies and its more than good enough right now@@spartan3299
You are the Master! When I can financially, I am definitely going to support your Patreon. You're an excellent teacher and instructional videos like these help tremendously. Thank you for your hard work each and every time! =)
Thank you so much for this video. I swapped out the m8 chip my quad had come with with an m10 and then decided to try to set this up. Must have watched this video 5 or 6 times. Flashed BF 4.5 on my new quad and then set GPS rescue up to a T as instructed in this video. Very first test of it returned to home successfully 5 times in a row. Only small hiccup is the altitude is all screwy and thinks it's higher than it is and descends way too fast. This would have saved my butt a few days ago when I fail-safed halfway up a mountain lol. Thankfully the VTX stayed on so I was able to find it and got some good exercise in the process.
Great setup guide... Once all my setings were dialed in my Chimera 7 lands flawlessly within feet of my take off point everytime. i find myself flipping on GPS rescue just for fun now and watching it out of goggles land like a Mavic.... well with a little more style lol
So you tested with Aux=FAILSAFE first and the drone returned home. Then you set the same AUX switch back to GPS Rescue.... Fly out far enough then turn off the radio? And the drone should kick into FAILSAFE mode and return home?
@@Wontonsoupz I always had the AUX switch set to GPS Rescue in Betaflight. With TX signal loss or flipping the switch manually the quad initiates return to home.
JB - Did I miss the part where you performed the 4th and 5th step under the "setup" section? : - enable a Mode switch that will activate level mode - in the Failsafe tab, set your Level Mode channel to activate Level 1 when in Stage 1. This will slow the quad down and level it out in preparation for the rescue.
This is exciting. Joshua, I wonder if you could do a complete updated video on a GPS position hold mod. I would like to also use an FPV for stills photography.
On the previous betaflight update Me and Droner Boner had a DJI goggles and DJI remote on a 03 unit and unplugged the goggles it went from 2 feet from the ground and flew way out and flew back to crash behind us. Very scary BUT when you done it on a switch it worked perfectly. We only tried this out because mine done the same on a long range flight. I seen the goggles loose connection. It came back in and was doing random hovering stuff till it flew away. I had remote connection the whole time. It would not do anything at all I tried my GPS switch. I tried disarming and everything. It just flew away... I specifically done a GPS test 2 baseball fields away before I done the long range flight. It returned back perfectly on the switch. So of course I felt confident to do the flight.
35:00 And a good advice would be to use the GPS-rescue mode in ordinary conditions for a few times till this switch will be comfortable and you will sure where is it. My first drone is now on the bottom of the ocean because I've switched the wrong one in the fog, when just lost the orientation of the drone(
Great video! I'm still new to all this. So, "Fail Safe" is for that oh SH$t moment and you flip the switch to get control again and the GPS return home is for like what, out of range or battery is dying?? Thanks for all you contribute to this :)
Thank you for everything you do Bardwell! One question though, I'm on 4.5.1 and everything is running perfectly. The only thing that I couldn't figure out was on the 27:05 mark where you're setting the "Period of time in Stage 1 failsafe after signal loss", yours defaulted to .4 seconds and I am unable to do anything under 1 second? It actually defaulted to 1.5 and I was out testing it and I'm very glad I was high enough when it finally kicked in. I would like to set it lower if there's a workaround for testing purposes although my GPS rescue is in fact working great!
¡Por supuesto, Carlos! Aquí tienes el resumen en inglés: Hi Joshua, I’m Carlos Viviano. I wanted to thank you for your videos, especially the one on configuring fail-safe and GPS Rescue. Following your steps, I was setting up my new Chimera7 Pro V2. On my first flight, I recently bought it, the drone flew away, and I lost connection with the goggles. I waited for almost 10 minutes, but it didn’t return. When I checked the last coordinates, it was about 300 meters high. I’ve been searching in areas with different parcels and farms but haven’t had any luck. Is there a way to track a drone’s GPS if it’s off or any tool you recommend to narrow down the search? Any advice would be greatly appreciated. Thanks!
Fantastic tutorial and testing, Joshua! Thanks a bunch! 😃 But a quad like that I'd definitely put iNav in it! Anyway, stay safe there with your family! 🖖😊
Yet again, thanks JB. If you get time can you think about this question please:- I have BF 4.4 on my two quads with GPS, both return to the correct point on triggering GPS rescue, but both fly back sidewards....... Any idea why and does BF 4.5 fix this? Keep up the great work mucker (English word for mate).
I'm the dummy who bought a GPS without SDA and SCL(not realizing), then needing a different fc on this build (without compass pads) thought my only option was the FT EZid. only my second time messing with these so I basically needed to know not all have a compass. that msp protocol seems interesting though.
The ascend rate and ground speed rate should be adjusted to something that matches a failsafe scenario. Default ground speed is 7.5 m/s. Should be around 30mph or 12m/s for a conservative 7" speed that gets you home but doesn't stress the battery (or do that repeated braking thing that you're seeing). I you're failsafing with a 7", you really want to baby the throttle and not ascend too fast, because chances are you're on top of a mountain, your battery is cold, and you really do not want any sag if you're trying to make it home. Set the ascent rate lower, down to 4-5 m/s instead of the default 7.5.
Galileo is the name European Union satellite consolation with 24 operating satellites as a posed to the USA satellite consolation called Navstar. Also, with 24 operating satellites. So, with it on in betaflight, it gives you access to 48 satellites instead of 24. I'm not sure which ones do or don't, but the gps unit has to be able to receive the signal from the galileo satellites, or it won't work. HDOP stands for Horizotal Dilution Of Precision.
Ehy jb. Appreciate your work a lot, thanks a million. Can you tell me what kind of facemask you applied on your goggles 2? I have the integra and even changing the pad doesnt fix the issues.
This is a font issue with AP and BF using opposite facing arrows for the same characters ( and Goggles 2 using hard coded BF font for its custom OSD). There’s an option to fix that - OSD_OPTIONS bit 5 is TranslateArrows.
Thank you for the tutorial. ❤ Do you have any idea, why gps acquision is very poor on btfl4.5? Sometimes on bad cloudy day it might lock 7 sats. But sometimes, even on clear days, gps sits there with zero sats for 30mins, until the lipo runs out. Even with vtx turned off. I know, that I have set it up correctly. In inav I always get no less than 14 sats in 2mins. I have even shielded and grounded gps wires. Btlf is so poor with gps, even on 4.5 version.
Hi Joshua, I have discovered a problem with BF 4.5.0. After updating from 4.4.2 to 4.5.0, the symbol for the number of satellites disappeared in my V2 glasses. However, the icon for the satellites is displayed in the OSD tab. Unfortunately, I cannot solve the problem. Do you have any ideas? If I go back to 4.4.2, the icon for the satellites will be visible in the glasses again. Many thanks in advance and best regards, Sascha
Hello and thank you for this video! I only have one question!! Its about the value on the stage 2 section the "Throttle hover". After testing on my osd the throttle % so I can hover is 27%. So I connect into BF, went on the receiver tab and my 27% throttle of the radio goes about into 1360 value. Is that an ok way to set it up? My quad is a 7" with a big liion battery and camera so I guess that this value looks excesive but normal if I count the weight? Thank you!
Does disarming reset the "maximum height during flight" value? Because if it does, then if you use "set homepoint once" you could fly home too low or something.
That's a great question and I don't know the answer for sure. I would guess that it does, and each time you re-set the home point, you also re-set the max altitude. But it's a pure guess.
@JoshuaBardwell At stage 2 settings at altitude mode you can set altitude at fixed altitude.That way the return altitude will be fixed at the desired value always.
Hi. If switching to ANGLE mode in Stage 1 (via Set instead of default Hold), does it have any effect on Stage 2 RTH settings (ie will it be able to reach maximum pitch angle like in AIR mode) ?
Joshua, in the current implementation it is impossible to set the compass to the correct position; when checking in the configurator, the copter model always twitches with the default value and tries to turn around if the correct compass position is set
2:10 My FC doesn't have SDA and SCL marked pads, but there are two UARTs for that. And manual for this FC have information where to connect your SDA and SCL wires, so it's not really true.
I hate waiting for GPS lock when it take a long time. I have found you can warm-up the m10 by plugging power into the USB. Then if you fly soon after it gets lock faster and you don't have to use battery power or overheat your VTX waiting. But how does that work? Is there a battery in the m10?
Joshua, question for recue mode with BF4.5. my drone is 1m away from me and motors are spinning bit but not enough to hovering. When turning on rescue mode, the drone suddenly jumpped up and hit a house's ceiling, crazy!! Old version of BF set disarmed and motors are stopped because of less than min distance to home. I wonder this crazy thing happens to your drone. To reproduce this, place a armed drone near you and set throttle up to spin motors, then turn on rescue mode. See your drone either disarmed or fly up to be rescue mode, Thanks!!! (or my geprc f722 aio is not compatible completly with new BF config)
I'm using the DJI controller 3+ goggles 3 with o3air unit, if either of the connection lost will it trigger failsafe (gps rescue)as well? Or it only work with elrs remotes?
Hi JB. Have you messed around with the gps rescue velocity pids? My Chimera 7.5 has a nasty vertical/pitch during the return flight. Apparently, messing around with the "gps rescue velocity" PIDs helps to fix this issue.
I've seen the entire video so many times and i don't know what am i doing wrong. Sometimes my home point arrow faces the correct way but most of the times it faces the complete oppsite way, exactly what happened to bardwell. I don't know how to fix it. Any suggestions?? Thank youuu!!
I thought betaflight heading was done automatically, even with or without a compass, or if arrow is wrong. It is calculating the GPS data if the quad is getting closer or not to home, adjusting angle/rotation/direction in small amounts!?
HI JB! How do you take over control of your drone when is coming back? It just happened that today mine activated, it returned to home, but I was never able to take over to continue flying.
Thank For your vidéo. It s the same for Walksnail vtx because i have problème to fix GPS with Walksnail vtx in betaflight 4.4 and all information of gps in osd . I see your video on This problème but all persiste 😢
If the altitude displayed on the OSD is different from the actual altitude, what can I fix? Please help me, experts. ;( Is it a problem with the barometer or a problem with the beta settings?
I have a weird problem. I set it all up as described in the video, then, when I simulated the failsafe by a flipping a switch the quad went into GPS rescue as planned, however, it didn't let me deactivate the failsafe by switching back. It kept flying back and crashed into my house because I launched too close (didn't intend to let it auto-land). What can be the reason that I wasn't able to interrupt the gps rescue?
@@JoshuaBardwell I waited a little to see if it works, then I flipped the switch back to take control, but soon I saw it didn't respond to my input. However, I'm not sure if I moved the sticks far enough to deactivate it. I'll test it again on a meadow where it can't crash into anything in case it insists to fly back! Anyways, thank you Joshua for your amazing tutorials! You are the best!
Is there any way to make gps lock faster? I would like to use it, but if i wait for gps lock on nazgul eco dc 5, it drains about 50% of 1550mAh battery. I have about half of flight time comparing to the normal start, without waiting for GPS to lock. This is silly :|
Could anyone share their PID tuning preset for Chimera 7 Pro V2 in Betaflight 4.5 RC4? Is it anyhow different from the iFlight old preset for Betaflight 4.3.2? Whether Betaflight 4.5 have any significant changes that require doing PID tuning differently?
What is the reason to use BF4.5 rather then Inav for a LR quad? I have no Inav experience but heared that it works just as wel.. and can hold attitude.
When you are testing GPS rescue you flip a switch to turn it on and you flip it off to retake control. But if it really fail safes how/when do you get control back?
@@JoshuaBardwell Waggle the sticks. Ok, got it. Thank you. It isn't something you can really just test and experiment with. Maybe set your TX to 25mw and fly behind some buildings to trigger?
i have a unrelated question about the 03 air unit iv watched your videos on it but im still having problems with a bad rx warning and ill also just fail safe outta nowhere even when im ten feet from the quad thanks in advance
BADRX means the receiver signal went away, and then when it came back the arm switch was in armed position. This would happen if the armswitch was in armed position on powerup, or if you had a failsafe during flying.
Is there a way to set the behaviour with a switch? for example when I know I'm flying in an area where I dont want gps rescue to happen it just disarms but when I fly in an area where it would be safe to have it on, it's on. Is there a way to do that?

Any idea why and does BF 4.5 fix this? Keep up the great work mucker (English word for mate).
I'm the dummy who bought a GPS without SDA and SCL(not realizing), then needing a different fc on this build (without compass pads) thought my only option was the FT EZid. only my second time messing with these so I basically needed to know not all have a compass. that msp protocol seems interesting though.
The ascend rate and ground speed rate should be adjusted to something that matches a failsafe scenario. Default ground speed is 7.5 m/s. Should be around 30mph or 12m/s for a conservative 7" speed that gets you home but doesn't stress the battery (or do that repeated braking thing that you're seeing). I you're failsafing with a 7", you really want to baby the throttle and not ascend too fast, because chances are you're on top of a mountain, your battery is cold, and you really do not want any sag if you're trying to make it home. Set the ascent rate lower, down to 4-5 m/s instead of the default 7.5.
my fpv hero !
Do you leave the Aux4 switch as FAILSAFE or do you change it back to GPS RESCUE after all the final steps?
Probably I would change it back to GPS Rescue.
Galileo is the name European Union satellite consolation with 24 operating satellites as a posed to the USA satellite consolation called Navstar. Also, with 24 operating satellites. So, with it on in betaflight, it gives you access to 48 satellites instead of 24. I'm not sure which ones do or don't, but the gps unit has to be able to receive the signal from the galileo satellites, or it won't work. HDOP stands for Horizotal Dilution Of Precision.
Thank you! I've been waiting for this video!
Ehy jb. Appreciate your work a lot, thanks a million. Can you tell me what kind of facemask you applied on your goggles 2? I have the integra and even changing the pad doesnt fix the issues.
Interestingly, Ardupilot has a known display port issue where the arrow is directly opposite. Is BF using similar code segments now?
This is a font issue with AP and BF using opposite facing arrows for the same characters ( and Goggles 2 using hard coded BF font for its custom OSD). There’s an option to fix that - OSD_OPTIONS bit 5 is TranslateArrows.
Hey Joshua, what kind of antennas are you using in this drone? Thank you. Keep up the good work.
Does betaflight detect your angle mode switch? you didn't set it on stage 1.
loving INAV
Thank you for the tutorial. ❤ Do you have any idea, why gps acquision is very poor on btfl4.5? Sometimes on bad cloudy day it might lock 7 sats. But sometimes, even on clear days, gps sits there with zero sats for 30mins, until the lipo runs out. Even with vtx turned off. I know, that I have set it up correctly. In inav I always get no less than 14 sats in 2mins. I have even shielded and grounded gps wires. Btlf is so poor with gps, even on 4.5 version.
It seems it would be handy to have a button that could set home.
Been waiting for this video..👊🏻
This was cool. Thanks. Also congrats on the fria.
Im awaiting a JB video next for "how to export the GPX file in 4.5 and use it to do map overlays" please and thanks!
Thank you so much Joshua !
Hi Joshua, I have discovered a problem with BF 4.5.0. After updating from 4.4.2 to 4.5.0, the symbol for the number of satellites disappeared in my V2 glasses. However, the icon for the satellites is displayed in the OSD tab. Unfortunately, I cannot solve the problem. Do you have any ideas? If I go back to 4.4.2, the icon for the satellites will be visible in the glasses again. Many thanks in advance and best regards, Sascha
thanks jb for posting this
Hello and thank you for this video! I only have one question!! Its about the value on the stage 2 section the "Throttle hover". After testing on my osd the throttle % so I can hover is 27%. So I connect into BF, went on the receiver tab and my 27% throttle of the radio goes about into 1360 value. Is that an ok way to set it up? My quad is a 7" with a big liion battery and camera so I guess that this value looks excesive but normal if I count the weight? Thank you!
Does disarming reset the "maximum height during flight" value? Because if it does, then if you use "set homepoint once" you could fly home too low or something.
That's a great question and I don't know the answer for sure. I would guess that it does, and each time you re-set the home point, you also re-set the max altitude. But it's a pure guess.
@JoshuaBardwell At stage 2 settings at altitude mode you can set altitude at fixed altitude.That way the return altitude will be fixed at the desired value always.
great video and as always i defiintely learned something today!!!!! Stay In the SKYZ Pilots!!!!!!!!!
Hi. If switching to ANGLE mode in Stage 1 (via Set instead of default Hold), does it have any effect on Stage 2 RTH settings (ie will it be able to reach maximum pitch angle like in AIR mode) ?
Can you bind the rescue mode to a button in order to completely shut it off or on if you would failsafe
Joshua, in the current implementation it is impossible to set the compass to the correct position; when checking in the configurator, the copter model always twitches with the default value and tries to turn around if the correct compass position is set
Can we also configure GPS/Compass hover as well? I've seen some videos but haven't yet found a video on how to configure it.
Betaflight does not have that function.
Sir i download betaflight configurator but i can't open it in my PC.please give me detail were i what file i open it. Thanks
Wow, thanks Joshua!
Where i get the purple lanyard like you used?
It was a giveaway item at Rampage.
2:10 My FC doesn't have SDA and SCL marked pads, but there are two UARTs for that. And manual for this FC have information where to connect your SDA and SCL wires, so it's not really true.
I hate waiting for GPS lock when it take a long time. I have found you can warm-up the m10 by plugging power into the USB. Then if you fly soon after it gets lock faster and you don't have to use battery power or overheat your VTX waiting. But how does that work? Is there a battery in the m10?
Don't just turn on "Use Galileo". I've had some GPSs that don't work when it's turned on. If it works though, afaik you should use it
Joshua, question for recue mode with BF4.5. my drone is 1m away from me and motors are spinning bit but not enough to hovering. When turning on rescue mode, the drone suddenly jumpped up and hit a house's ceiling, crazy!! Old version of BF set disarmed and motors are stopped because of less than min distance to home. I wonder this crazy thing happens to your drone. To reproduce this, place a armed drone near you and set throttle up to spin motors, then turn on rescue mode. See your drone either disarmed or fly up to be rescue mode, Thanks!!! (or my geprc f722 aio is not compatible completly with new BF config)
I'm using the DJI controller 3+ goggles 3 with o3air unit, if either of the connection lost will it trigger failsafe (gps rescue)as well? Or it only work with elrs remotes?
Hi JB. Have you messed around with the gps rescue velocity pids? My Chimera 7.5 has a nasty vertical/pitch during the return flight. Apparently, messing around with the "gps rescue velocity" PIDs helps to fix this issue.
First thing to do is make sure your GPS is operating at 10 Hz. If it's a 1 Hz GPS then that explains the issue.
Thank you I’ll verify the gps freq.
@@JoshuaBardwellyes it is set to 57600 in ports tab
Isn't a barometer better for the auto landing? Betaflight should use it like inav does
It uses barometer if there is one.
Very helpful. Thank You
I've seen the entire video so many times and i don't know what am i doing wrong. Sometimes my home point arrow faces the correct way but most of the times it faces the complete oppsite way, exactly what happened to bardwell. I don't know how to fix it. Any suggestions?? Thank youuu!!
I thought betaflight heading was done automatically, even with or without a compass, or if arrow is wrong. It is calculating the GPS data if the quad is getting closer or not to home, adjusting angle/rotation/direction in small amounts!?
Heading is reported by the GPS receiver. But Betaflight also estimates heading by integrating the gyro.
There is no interference from the electromagnetism of the motors, battery in the compass?, this happened in the old F330 and F450 drones.
Yes, there is such interference. Unless you can put the magnetometer some distance away from the motors and antennas, it's not very useful.
hdop seems to have changed to pdop in final build
HI JB! How do you take over control of your drone when is coming back? It just happened that today mine activated, it returned to home, but I was never able to take over to continue flying.
You deflect the sticks past like.... I think it's 24%
My man! I just tried right now and worked! I saw your replied as I was finishing flying and then gave it a try. Thank you! ! ❤
Thank For your vidéo. It s the same for Walksnail vtx because i have problème to fix GPS with Walksnail vtx in betaflight 4.4 and all information of gps in osd . I see your video on This problème but all persiste 😢
Is this a grasshopper you are holding in your hand, JB?😅
If the altitude displayed on the OSD is different from the actual altitude, what can I fix? Please help me, experts. ;(
Is it a problem with the barometer or a problem with the beta settings?
Hi Joshua
I saw you updating the chimera to 4.5
Did you fly it on the stock pids
Or did you use the iflight 4.3 pids from iflight
Thanks for your time
I used stock PIDs.
@@JoshuaBardwell thanks!!
I have a weird problem. I set it all up as described in the video, then, when I simulated the failsafe by a flipping a switch the quad went into GPS rescue as planned, however, it didn't let me deactivate the failsafe by switching back. It kept flying back and crashed into my house because I launched too close (didn't intend to let it auto-land). What can be the reason that I wasn't able to interrupt the gps rescue?
After you kick out of GPS rescue, you must deflect the sticks at least, I think it's 25%, to get control back. Did you do that?
@@JoshuaBardwell I waited a little to see if it works, then I flipped the switch back to take control, but soon I saw it didn't respond to my input. However, I'm not sure if I moved the sticks far enough to deactivate it. I'll test it again on a meadow where it can't crash into anything in case it insists to fly back!
Anyways, thank you Joshua for your amazing tutorials! You are the best!
Great Guy ! Nice and Thanks !!!!
Is there any way to make gps lock faster? I would like to use it, but if i wait for gps lock on nazgul eco dc 5, it drains about 50% of 1550mAh battery. I have about half of flight time comparing to the normal start, without waiting for GPS to lock. This is silly :|
I also have iflight chimera 7. Would i be able to plug in these same values to setup rescue
how to enabled or disabled gps with remote switch on betaflight?
Thanks Joshua
In the middle of the video, a mark appeared on the head from a successful GPS RESCUE?
Did they ever fix gps locking issues?
Could anyone share their PID tuning preset for Chimera 7 Pro V2 in Betaflight 4.5 RC4? Is it anyhow different from the iFlight old preset for Betaflight 4.3.2? Whether Betaflight 4.5 have any significant changes that require doing PID tuning differently?
What is the reason to use BF4.5 rather then Inav for a LR quad? I have no Inav experience but heared that it works just as wel.. and can hold attitude.
For a LR quad, iNav may be preferable. Betaflight has better acro performance, as well as some features that iNav lacks.
What to do if gps rescue make the drone go really fast up and never stop ? Even in landing when I drop value 😅 pls help I’m no expert
When you are testing GPS rescue you flip a switch to turn it on and you flip it off to retake control. But if it really fail safes how/when do you get control back?
When you regain link, you deflect the sticks past 25% to retake control.
@@JoshuaBardwell Waggle the sticks. Ok, got it. Thank you. It isn't something you can really just test and experiment with. Maybe set your TX to 25mw and fly behind some buildings to trigger?
Does Betaflights GPS Rescue even take advantage of a compass if you got one?
Yes.
For comparability, does this mean I need to update my FC firmware on 4.5.x? In addition to Betaflight 4.5?
Can u explain failsafe settings for elrs module or transmitter
What we need for r2h to work
i have a unrelated question about the 03 air unit iv watched your videos on it but im still having problems with a bad rx warning and ill also just fail safe outta nowhere even when im ten feet from the quad thanks in advance
BADRX means the receiver signal went away, and then when it came back the arm switch was in armed position. This would happen if the armswitch was in armed position on powerup, or if you had a failsafe during flying.
I hope they don’t get rid of NMEA it’s all my Hakrc flight controller will run on one of my favorite old quads
Don't flash 4.5 then.
Is there a way to set the behaviour with a switch? for example when I know I'm flying in an area where I dont want gps rescue to happen it just disarms but when I fly in an area where it would be safe to have it on, it's on. Is there a way to do that?
No that's not possible.
