Correctly configured Failsafe is super important for your, your drone's, and others' safety. In Betaflight (or INAV) you might be tempted to use the Failsafe flight mode that can be found in the Configurator's Modes tab. But, don't use it! It's a legacy, absolutely obsolete way of configuring and working with the failsafe of your drone or RC airplane. All modern radio systems will communicate a failsafe state in a way that does not require you to worry about this flight mode at all.

I agree 100%, INAV should remove the failsafe mode and add land mode 😁😉
I know 😆
@@FPVUniversity Are there plans for land mode? I know you can autoland, what is next on the roadmap there?
no plans I'm afraid
Maybe remove dead wood like 'Killswitch' and 'MC braking' too. One is frustrating and the other often doesn't brake.
what if I want to test my failsafe configuration? is this a good reason to set failsafe aux channel?
Radio receiver "Failsafe mode" is obsolete, configuration of lost receiver radio signal in flight controller software configuration is a very important safety feature. (not obsolete)
"Failsafe flight mode is obsolete" leaves some confusion. Perhaps flight controller software should rename to "Emergency Mode" to differentate? For rotors, a "hold and decend" at controlled decent rate would be good option (as land implies an end state that may not necessary be achieved). For wings, a "loiter and decend" would be helpful. Both should offer options for RTH (return to home) as an initial "Emergency Mode" action.
Yes I'm confused 😕 🤔😂
I use Crossfire and have been having failsafes on my 3" quad. The reason is that, for some reason, my NanoRx is loosing power from the FC. So, the radio link is great because of I use Crossfire, but a HW issue causes failesafes. So, maybe it's still good to configure failsafe. even with new RC links.
Hey Padwell I had a motor burn out on fail safe RTH on iNav 3.0 cause i crashed and it flip upside down. Has there been anything to try and a identify a crash happening with Radio connection lost to cut motor from going into over drive? i know that the value of G-force can be taken into consideration of sensor of indication.
I always used this mode to test if drone would ascend or descend with certain props and throttle value. And i will wont stop using until You will remove it ;P
Pawel, I suggest your recommendation makes sense for fixed wing flyers but not multicopters. With a multicopter, we feel it is a wise safety feature to have Failsafe available on a switch.
Why? RTH has own mode and Disarm is already on a switch. So why to have this 3rd option?
@@FPVUniversity because there is a stage 1 which will prepare the quadcopter to a good GPS Rescue (if well configured).
Makes sense… As long as the RED parachute is triggers via Rx, we should be good…😊🖖🏻
Thanks Pawel!!
How about if you want to test if RTH failsafe is working properly? Just turn off the radio instead?
Turning of radio is dangerous. In some radio, all switches must be back to normal position when it's turned on, which means you'll have to disarm your air craft on the sky. I destroyed my Dart because of doing it.
I wouldn't want to turn off my radio if the model is flying! Surely it's better to set a failsafe channel just for this test, then disable it afterwards.
"failsafe" is for non-GPS rigs. RTH is a GPS-rescue which will work fine if you have programmed it properly. Nurk has a video where he goes through turning off his radio and playing panic while it drops from the sky. You can re-arm, he does it. It's called something like "finally got gps rescue to work"
To test RTH use RTH mode. And you can test Failsafe at home on a workbench
@@FPVUniversity If you test Failsafe on the bench by switching off the radio, how can you tell if the FC has gone to RTH mode if the aircraft doesn't have FPV gear?
I have a holybro Kakute F7 and PH and RTH work ok. I can do Mag calibration with sticks and hear the beeps from the drone,
also I load WP to FC and hear the beeps. I built a new drone with Matek 722 SE and can not not hear the beeps from drone when I do mag cal with sticks.
My PH and RTH do not work either...any Ideas? Thanks.
My mag orientation looks OK in configurator. Tried both 4.1.0 and 3.1.0 and same problem.
I respectfully disagree. I had a flight that made me change back to using the failsafe mode rather than using the built in failsafe detection. The problem was it would not let go of the failsafe condition after the RX signal came back. After that flight and bench tests, I always set the Crossfire to send the correct modes to start the failsafe condition. I tested this on the bench and it is the only way my plane would go into failsafe and come out of it properly. That was version 2.5.1 and I continue to set my planes up using the mode, not the auto detection. This video was the time it happened in a flight. I would strongly recommend to keep failsafe mode around. Anyway watch the video footage and I also recommend some bench testing. (Go to the back yard and get sats and try failsafe.) Maybe it's only a Crossfire issue. A few years ago I had Dragonlink v2 receivers and the mode was the only way to set up failsafe on it and that works perfectly with iNav / Crossfire and other receivers as well. czcams.com/video/JBd1i0JWAn4/video.html
Oh yeah, I almost forgot. THANK YOU!!!!!! for all the cool stuff you do. Without you and your development team we would have given up on the hobby (Just kidding I can't quit, we would just be stuck with DJI flight controllers without you guys :)
yesterday we did try failafe with the new betaflight rc6 and a new lrs reciver arrow did point correct way and when my friend did remove the module the drone lifted from the ground but in the wrong direction and almoust did not climb much also. He did manage take controll and land the drone safe. But why did this happen. Is it the Reciver fault ore the FC faults. yesterday he did same test with different reciver and it did work problem was that elrs reciver had very bad range.
Ardupilot's failsafe & RTL implementation from 10 years ago make today's failsafe implementations in Betaflight look like a joke.
Great information again thanks
Why not remove these confusing modes ? I crashed a drone playing with FAILSAFE...
Hello I have a drone and when throttle between -75 to -100% the yaw, roll and pitch do not work. When throttle stick is in up position to -74%
and more then yaw , pitch and roll work. Where is the parameter in CLI that controls this behavior.
I would like to change it to have yaw, pitch and roll work when Throttle at lowest position -100%. Thanks.
You should enable airmode, although it is weird that they stop working at -75% already. Maybe you should also adjust your throttle curve, but airmode is what keeps the motors spinning even with no throttle.
i use failsafe setting when i first set up a craft or make firmware changes just to test what the fc is going to do when it failsafes
I feel like this video's title would have been more on-brand if you titled it;
"FAIL-SAFE IS DEAD"
😉😁❤️
Yeah, my trademark 🤣 @xjet has "overregulation and rules" I have this
It happened to me to lose or to have a very bad video link while flying FPV. I was happy to be able to trigger failsafe to ease the landing of the quad instead of disarming it (I'm using Betaflight). Or to check if the rotor speed for descent is okay.
I just upgraded INAV to version 4.1. I went to add the mode RTL and found that it is missing, so I created the mode Failsafe to RTL. This sounds like it is the wrong way. What happen to RTL in the flight modes? I am using a MATEK F4 flight controller.
If this is a drone, you need enabled and configured baro, mag and gps to have RTH mode
Thank you so much.
its good for testing so you don't have to actually turn off your radio.
And THIS is my problem with INAV...new features, new features, new features....and all that old stuff, no one needs anymore, but its there - and confusing ppl, if not watching all that videos and reading all that thousends of forum threads to know that....
FIX THAT!
And then, everytime we drop an old feature there are those people who complain why we dropped it as they need it so much!
Hi Pawel, where do you get the inspiration for the video's thumbnails?
Every month I make like 30-40 photos with different facial expressions. And then, when I need a thumbnail, I just go through the archive and get something that fits :)
Thanks!!
Excellent, Pawel! Thanks a bunch! 😃
Stay safe there with your family! 🖖😊
