Man, as a newbie to the world of fpv, I can't express how useful you've been. I can type in anything and you've made a video on it which answers my question every time. The fact you give this information out for free is commendable - especially when others shamelessly exploit beginners for information which is already available for free. Thank you Josh, you're a legend!!
This series is the best walk through of anything ever... and the timing for me has been just like your doing this to suit my own personal need for help on betaflight.😆😁
It's interesting that the 'likes' are lower here than the rest of the series. I have a lot of quads with GPS because I'm not a racer and use my quads on trips in the mountains or interesting places (formally with crossfire and now with ELRS. ) In my planes I use INAV generally but I do have explorer quads with betaflight with GPS's without compass so this is a pretty interesting video for me. Although my favorite quads are my 5" fun flying (no GPS) screamers even though I'm no where near great at freestyle. This has been my favorite series from JB! As comprehensive as I could've ever wanted. I've learned something on every video so far!
This series is great! I’ve learned so much from every video, even on tabs I thought I knew pretty well, still learned something. I really appreciate what you do for the hobby JB! You could have charged a lot of money for this series alone and I would’ve bought it. This series could not have come at a better time 🙏
Doesn't the accelerometer, that every drone has, allow it to know if it's accelerating up or down to set the correct throttle level to slowly descend? Is there a practical reason it's not implemented?
Ahhhhhhhh now I get it??? Thank you again Joshua! Thank you for keeping my brain from exploding! I'm struggling but havnt given up! Just lost all setting on my nazzgul evoke and never flown it yet. I'm watching vid now to try n get custom setting up. Thanks again.
Well, I thought I set up my GPS correctly, went out to test RTH today, sadly flew up way to high, seemed to yaw for a while, then disarmed. Luckily I was in a wide open space with no people or property around, but I didn't even hear my drone fall, no idea where it went, but before the VTX cut, I saw it fall. Make sure you read the wiki and check off every warning, or you'll lose your drone like me, gutted :(
There is a post from Chris Thompson where He says to set the Stage1 throttle a little bit higher than the hovering value so that quad starts gently climbing while entering in Stage1. And a good duration of Stage1 should be around 1.5 seconds. That is, if I well remember.
How does the FC know when to enable return to home? If I loose signal or turn my radio off the control values will automatically drop below 1000? Do I have to set anything is the modes section of betaflight or only select RTH in the failsafe section?
Hmmm... seems pretty trivial to measure the throttle required to (nearly) hover for whatever weight you happen to be flying. Then using a delay of 10 or 15 seconds, you now have some time to alter your TX position to see if you can regain the comm link. If not, the timer expires and it drops out of the sky like the "drop" mode you suggest. Why not give yourself a chance to recover signal before immediately dropping? Especially, if you happen to be flying over something like a lake at the time.
hello from Greece. I have assigned a switch to enable gps rescue to check if it works and when i need it, say i loose video feed etc and i would like the quad to start returning. After flashing Betaflight 4.3 and seting everything up from scratch i went out to test the quad. After flying around i enabled the gps rescue switch,400 meters away and the quad behaved like stage 1 failsafe and dropped. Recovered and had a broken arm. I saw in betaflight that the failsafe switch was to stage 1 but i dont have failsafe switch enabled i have gps rescue so why did the quad fall down from the sky?? I have the Nazgul5 Evoque F6d HD version. Thank u
Hey Joshua, quick question for you. Let's say I enable the 'Allow arming without fix' function, but at the time of arming, I happen to have more satellites than the required minimum. In that case, would the GPS rescu be enabed ?
JOSHUA - i am so ready to learn something today so help me out if you can. nobody ever could answer me this question about GPS Rescue Altitude mode@ 16:45min so we got: - MAX altitude - FIXED - CURRENT now here is the thing. i often fly over clouds just because i can where i live. and i have it on FIXED GPS rescue at 80m. i climb up to lets say 2000 meters. then i see my battery getting lower and i start to decent. at 1500 meter height a cloud is moving between me and my drone so i loose video signal. ! if i failsave with switch or crossfire signal loss - does that mean the quad will go down to 80 meters and then try to fly back? or does it mean it will ignore my set fixed altitude of 80m and try to go back up to 2000m because that was the highest point i fly, draining the battery to zero and quad will be lost? ! sometimes the quad drifts away due to strong winds up there and i am at the edge of a failsave. means i was tempted multiple times to switch on GPS rescue but never dare to do that because nobody could explain what will actually happen if the flown altitude is much higher then what i set before. i would love to hear that fixed altitude means the quad will go UP or DOWN whatever it takes to reach the height you set and THEN try to fly back to the home point. do you have any knowledge what will actually happen in this case? thanks alot for everything you do for our community. keep the blue side up° ☀🌌⛅🌈
I would like to have a mix of Stage2 failsafe, have it auto level first and then fall off the sky, this way the odds of it landing upright are increased. I do not want it to check if it is leveled, just try to do it and fall off either way. Motor RPM could also be used to figure out if the quad got stuck somewhere but I think thats way too much, if you're failsafing then something is very wrong.
Hi 👋 JB, great 👍 series I’m learning a lot. I mAde the mistake of buying a qx7 accst. Now I had to buy rxsr for my Darwin baby ape. So what would the values look like for failsafe 1 with the rxsr? Also I didn’t flash to the 4.3 because of the problem I had with rxsr. I was able to recover it in Frsky’s hidden DL page thanks to your video. So you mentioned bind and fly’s on your first video. That the developers might have pre sets. So in the back up file it basically just says 4.2.5 firmware. So if something goes wrong would all I have to do is reflash the old firmware?? Thanks again for all your YT content.
Ok they just need a toggle button that does all of this for you. Select your Flight Controller, select what size drone (3, 4 or 5inch) Then it automatically configures everything for you so you can start flying. Then if you want you can go back and adjust as you want. This is all amazing information and I know how to do most of this but the learning curve for a new pilot is not getting easier it is getting harder.
Its made this way to force you to learn so you don't accidentaly make your quad dangeorus. However, with BF 4.3, easy presets are available for everything
Another close range failsafe to look out for is antenna loss on rx. Had it both with knocking of elrs ceramic and ufl disconnecting. Manifests as stage 1 at close range and then stage 2
Has the Minimum Distance to Home parameter been removed from Betaflight 4.2.11? I am unable to find it in Configurator but I don't see anything mentioning its elimination from the changelogs.
All those tutorials are great... Btw some of them I just downloaded as reference on the field Thanks Joshua ☺️. One thing I still not sure how it works... Yesterday I updated my quads to FrSky Access, using F.Port, and one of them was not working... (telemetry and commands from my RC)... Then I found out a bad contact in the receiver's connector with the cable (F.Port), after moving it a bit, worked perfectly, and no more problems. But, what if this happen again during the flight ? (I mean, The receiver and the RC are communicating but the Receiver and ESC aren't). Would the Failsafe be fired by the Throttle "inactivity" ??? (I know this video was released a long time ago, but perhaps is a good question, I did not find many topics about it on the Internet). Fly safe guys :)
Joshua, you should talk about gps_rescue_landing_alt and gps_rescue_landing_dist. The 2 settings define a cylinder around the home point that will cause GPS Rescue to try landing inside. But noboby talk about that.
It would be cool to see your parameters of gps rescue parameters you and other people use for GPS Rescue Tab numbers especially for differents size/5"-7" frames models with thrust to weight ratios!!
@@kaskobi3657 yeah I don’t own a computer. Only ever used iPhone but I’m going to buy a computer so I can look over that stuff and I’d like to change my rate also. I started with the DJI fpv and that was what was good about that as you could do everything on my iPhone or goggles. Thanks.
Would it be possible(besides the question if it would be smart) to disarm and then rearm your quad mid flight to gain/reset a home point and enable gps rescue that way? In the case you were not able to lock on enough sattelites at the moment of the initial arming.
Ok I watched this video a few times. I’ve seen all Your videos. But this one in particular. I got a bind and fly from Geprc. The Crocodile 75 V3. I plugged it into beta flight to make sure the GPS rescue was set. While I was watching this video on the failsafe tab. You said the throttle should be sent to auto. Geprc has it set to SET, And the number right next to it is 1500. My question is should I leave it the way it is or put it the way you said to put it.?? Can you please help me out because I’m confused now
I have no idea why they would lock throttle at 1500 on failsafe. Maybe they know something I don't. GEPRC aren't likely to have made a silly mistake, but personally I think there must be something else we're missing for that setting to make sense.
@@JoshuaBardwell when it comes to Beta flight and drones, I take your word for it. Because everything I learned about FPV. I learned it from your RUclips channel. So im going to change it to Auto and just see what happens next.
Great video - as always. How do I regain control in a failsafe gps rescue: Ideally the quad flies up and then I already regain a link. Does it just somehow tell me to fly again myself? Otherwise it returns to the home point and crashes into the ground. How do I regain control say 100 meters out to keep it from crashing?
It reconnects and you will see RSSI go back and show connection, and then you move the sticks to take control. Once it reconnects, you have to deflect the sticks at least something like 20-25% I don't remember the exact number to take control again.
@@JoshuaBardwell Awesome. Thanks. Will have to see how to show RSSI in the goggles but you probably have a video for that ;-) Used pur DJI/vista so far, just jumped to ELRS.
If set to auto Betaflight default stage 1 failsafe behavior throttle goes to low. It means that throttle goes to minimum valid pulse range right? Quad just falling for 0.4 second?
I have a question regarding allow arming when fixed, what happens when you have not set this slider, so Betaflight does not arm without having a certain amount of satellites and then you fly, crash and disarm. In the new position satellite reception is not as good and you loose a couple of satellites so that the number you have is below the minimum amount. Will the quad then not arm again?
@@JoshuaBardwell interesting, sounds like a reason to me to set allow arming without fix. Or maybe it realizes that it has not reached the homepoint and the homepoint stays until the fc is rebooted. I wonder how I can try that.... btw thanks for answering on an 8 months old video. I have to send you a tip now, since I'm also binge watching all your bf 4.3 videos.
😢 just lost my brand new build drone today. Been flying for many years. Second time I lost a drone. I realised I forgotten to set the fail-safe. Darn it. I'm so upset.
I am still a bit confused about how best to set up the failsafe aux mode switch in order to test that GPS rescue is functioning as it should. I did set up an aux mode on a momentary switch for failsafe and under the failsafe tab, I had the failsafe switch action set to Stage 1. Under the Channel Fallback Settings for that aux channel, I had in configured to set at 2000 as that is the value that activates the failsafe switch on the modes tab. When I tested this in the field the quad went into GPS rescue and flew back to my take-off location but I could not regain control of the quad and it ended up crashing. I'm thinking where I went wrong is that I should have set the Channel Fallback Settings for the aux channel that triggers failsafe to hold instead of set. Does this sound correct?
It's possible that your failsafe aux setting prevented the FC from leaving failsafe aux mode. I'm pretty sure the failsafe aux mode needs to be set to "hold" not "set" to work properly. If you go into GPS rescue and can't regain control, most likely it's because you did not deflect the sticks enough. Once link is re-established (or you release the failsafe aux switch) you must deflect the sticks at least, I think it is 25%, before the FC gives control back to you.
@@JoshuaBardwell Great, thanks for confirming the use of "hold" instead of "set" for that aux channel, that does make sense. I was trying everything to regain control as the quad was drifting down. The only thing I didn't try was turning the radio off and on again.
I recently flashed 4.3 and I get rx loss warnings i don't ever failsafe i usually run 100mw but thought to try even at 1000 mw it still says rx loss and maybe only 50 feet away it never actually acts like it's about to fall out of the sky and my rssi dbm is fine along with the 6:100 range thingy sorry don't remember the name for that hehe...so odd as it litterally only happened with the new flash ever heard of this anyone?
If the quadcopter instantly flips over when you arm and raise the throttle with props on, it is almost 100% certain to be one of these things: 1. Clockwise prop installed on counter-clockwise spinning motor or vice versa. 2. Flight controller not facing forward. Go to the Setup tab in the configurator. Tilt the quadcopter on all axes (pitch, roll, yaw) with your hands. The 3D model in the configurator should move the same as you move it with your hand. If it does not, use the Board Alignment parameter in the Configuration tab to fix it. 3. Motors not wired correctly. TAKE OFF YOUR PROPS. Plug in a battery. Go to the Motors tab. Turn on the "props are off" slider in the lower-right. Raise the individual sliders (1, 2, 3, and 4) one at a time, just enough that the motor begins spinning. The motor positions (1, 2, 3, and 4) should match the graphic in the upper left. If they do not, then either move the signal wires so that they are correct or use resource reassignment to virtually "move" the motors. 4. Motor spinning wrong direction. Do the same as step 3 but compare the motor direction to the arrows on the graphic in the upper left. If a motor is spinning the wrong direction, either reverse it using BLHeli (or whatever ESC software you are using) or swap any two motor wires with each other, which will reverse the direction. Many times, people swear up and down they have checked all of these things, and then come back to say oops I missed one you were right. So if you think you have checked all of these things and your quad still FLIPS OUT, go back and check again. If your quad is insta-flipping on takeoff, it is almost always one of these things.
Regarding Failsafe....I tested GPS Rescue with the aux switch on my 5 inch. But still haven't got the guts to turn off the radio in a field 100 meters away to test. I'm using TBS nano receiver. I've seen a video where the author indicated he had to put the TBS receiver into Failsafe = Cut. before GPS Rescue would work. The default is Fs Pos. Anybody have experience with this?
The default for crossfire is definitely cut not pos, and that's definitely what you want unless you're flying a servo plane with no flight controller. Test by using failsafe aux mode. Don't power off your controller.
Betaflight has this capability but it disables it shortly after arming. If you tap an obstacle you don't want the quad to just drop out if the sky. You want to be able to keep flying.
@@JoshuaBardwell In that case yes, but I was talking about the failsafe landing procedure. As it's automated, Betaflight could guess that the quad has touched something and it has to disarm to avoid to cause collateral damage.
No offense this is great but a summary of all videos would be awesome. The total time of all these videos make it hard to set up with batteries. If you make a summary video with less explanation you would get over a million views in a few months. Think of beginners wanting to get into the air fast. 1:53

Your content is near solely responsible for me finally taking the leap into real fpv gear. Thanks for being an educator.
This series is the best walk through of anything ever... and the timing for me has been just like your doing this to suit my own personal need for help on betaflight.😆😁

Yes
I have a question regarding allow arming when fixed,
what happens when you have not set this slider, so Betaflight does not arm without having a certain amount of satellites and then you fly, crash and disarm. In the new position satellite reception is not as good and you loose a couple of satellites so that the number you have is below the minimum amount. Will the quad then not arm again?

I'm thinking where I went wrong is that I should have set the Channel Fallback Settings for the aux channel that triggers failsafe to hold instead of set. Does this sound correct?
It's possible that your failsafe aux setting prevented the FC from leaving failsafe aux mode. I'm pretty sure the failsafe aux mode needs to be set to "hold" not "set" to work properly.
If you go into GPS rescue and can't regain control, most likely it's because you did not deflect the sticks enough. Once link is re-established (or you release the failsafe aux switch) you must deflect the sticks at least, I think it is 25%, before the FC gives control back to you.
@@JoshuaBardwell Great, thanks for confirming the use of "hold" instead of "set" for that aux channel, that does make sense. I was trying everything to regain control as the quad was drifting down. The only thing I didn't try was turning the radio off and on again.
First like, then watch
I recently flashed 4.3 and I get rx loss warnings i don't ever failsafe i usually run 100mw but thought to try even at 1000 mw it still says rx loss and maybe only 50 feet away it never actually acts like it's about to fall out of the sky and my rssi dbm is fine along with the 6:100 range thingy sorry don't remember the name for that hehe...so odd as it litterally only happened with the new flash ever heard of this anyone?
I'm having issues finding the correct download link for Betaflight. Can you help me?
It's in part 1 of this series. Playlist link is in the video description.
@@JoshuaBardwell I found it. I appreciate it
Please I have a problem with omnibus f4 board …..when I throttle up the drone just flips forward or backwards how can I fix that ?
If the quadcopter instantly flips over when you arm and raise the throttle with props on, it is almost 100% certain to be one of these things:
1. Clockwise prop installed on counter-clockwise spinning motor or vice versa.
2. Flight controller not facing forward. Go to the Setup tab in the configurator. Tilt the quadcopter on all axes (pitch, roll, yaw) with your hands. The 3D model in the configurator should move the same as you move it with your hand. If it does not, use the Board Alignment parameter in the Configuration tab to fix it.
3. Motors not wired correctly. TAKE OFF YOUR PROPS. Plug in a battery. Go to the Motors tab. Turn on the "props are off" slider in the lower-right. Raise the individual sliders (1, 2, 3, and 4) one at a time, just enough that the motor begins spinning. The motor positions (1, 2, 3, and 4) should match the graphic in the upper left. If they do not, then either move the signal wires so that they are correct or use resource reassignment to virtually "move" the motors.
4. Motor spinning wrong direction. Do the same as step 3 but compare the motor direction to the arrows on the graphic in the upper left. If a motor is spinning the wrong direction, either reverse it using BLHeli (or whatever ESC software you are using) or swap any two motor wires with each other, which will reverse the direction.
Many times, people swear up and down they have checked all of these things, and then come back to say oops I missed one you were right. So if you think you have checked all of these things and your quad still FLIPS OUT, go back and check again. If your quad is insta-flipping on takeoff, it is almost always one of these things.
@@JoshuaBardwell okay thank you very much and I will check everything again
You were right the motor position were wrong and after changing it flies well
Regarding Failsafe....I tested GPS Rescue with the aux switch on my 5 inch. But still haven't got the guts to turn off the radio in a field 100 meters away to test. I'm using TBS nano receiver. I've seen a video where the author indicated he had to put the TBS receiver into Failsafe = Cut. before GPS Rescue would work. The default is Fs Pos. Anybody have experience with this?
The default for crossfire is definitely cut not pos, and that's definitely what you want unless you're flying a servo plane with no flight controller.
Test by using failsafe aux mode. Don't power off your controller.
amy i ask how to disable battery low voltage fail safe?
You gotta update your configurator :)
Isn't there a bug in betaflight 4.3 that prevents gps rescue on fail safe from working?
Every time I save with GPS mode selected, it goes back to selecting the "drop" option. So I think you're right.
Um, arm without GPS lock has been removed?? A lot of options seem to have been removed. 🧐
Depends on what betaflight version you have, in earlier versions, that setting can only be acceesed through CLI
@@kaskobi3657 I found out that I hadn’t updated the FC firmware, I thought I had. This gave me the extra options.
😍😍😍😍😍😍😍
10:30 : Actually, using the gyroscope data, betaflight should be capable of figuring out when the quad touches something and disarm instantly.
Betaflight has this capability but it disables it shortly after arming. If you tap an obstacle you don't want the quad to just drop out if the sky. You want to be able to keep flying.
@@JoshuaBardwell In that case yes, but I was talking about the failsafe landing procedure. As it's automated, Betaflight could guess that the quad has touched something and it has to disarm to avoid to cause collateral damage.
Oh I see. Yeah it does have sanity checks that monitor the gyro and PID error and such. But it's not very reliable.
No offense this is great but a summary of all videos would be awesome. The total time of all these videos make it hard to set up with batteries. If you make a summary video with less explanation you would get over a million views in a few months. Think of beginners wanting to get into the air fast. 1:53
