Hello random guy on the Internet, this is excellent advice regarding failsafes, especially the distinction between S.Bus and PPM. I'm a quad, or Betaflight, guy, so while I'm used to the layout, functions, and terms used for iNav, I've been watching videos like yours to guide me through my first GPS fixed wing installation. Many thanks for sharing, Pawel!
I thought hold meant the receiver sends the stick output you configured on your receiver. You can do this with the most Frsky receivers when there's connection between the transmitter and the receiver, placing your sticks and programmed switches into the desired position and short press the F/S Button on your receiver. Anyway, you right Pawel, it's always necessary to setup AND TEST your failsafe mechanism!
Hold, holds the last commanded stick positions when the failsafe happened. What your talking about would be the custom setting, where you can set a pre determined stick/switch command when failsafe happens. Many other protocols or cheaper radios would use such a failsafe.
Can you go out to the field and prove that this works? I have extensively tested inav emergency landing using no pulses and it works perfectly with FrSky SBUS gear.
No pulses setting works correctly since the beginning of the times. It works in the BF and also the INAV. All the possible failsafe procedures like Drop, RTH, GPS rescue. All the "modern" receiver protocols (sbus, fport). As you are telling in the video - the FC knows that receiver is without a signal from a flag bit, so the channels values are irrelevant at this moment. So why would I ever need to set it to hold? I'd appreciate a typical scenario when the no pulses will not work and hold will. And yes, I've tested all my F/S settings in the bench first...
Pawel, can you please explain the correct procedure of Failsafe for us EZUHF uses..? PPM does not have a "No Pulse" or "Hold" option, so I assume we need to set a conventional "Hold" using EZs standard FS procedure, ie Bind button pressing. May I suggest separating Failsafe options inside iNAV depending on the TYPE of craft chosen..?
HI Pawel ! can not disarm after failsafe. props are spinning . Only unplugging the battery stops the motors. Can you help me ? I put RTH mode in failsafe tab but I have no RTH in Modes ( gps receiver without compass) and the switch works as failsafe only . I use frsky and expresslrs. Thanks
Pawel i use for my receiver the L9R, but the taranis radio in order to Bind it you have to set the internal Rf Mode to LR12, with this on the radio failsafe does not show any option whether to select Hold, no pulse etc. Can you explain this since there is no indication for this on the radio. I did a no pulse failsafe procedure on the L9R rx as which was written on its instruction manual by quickly pressing the FS button on the Rx to activate the no pulse feature on the rx. Will this be work to create a proper FS even if the radio transmitter does not indicate any FS choice?
Many thanks, but I need to clarify, for all frsky receivers then I will have to set the radio to holt, currently I had it on no pulse, and works on the bench but even do works in the bench do not means will work in the air, I learn my lesson 3 years ago, the plane flight away never to be found, so for R9slim, R9 receiver set the radio to hold, correct? Now for the crossfire micro i got it to cut on the crossfire module and seem to work. This morning I will do a test by driving, leaving the transmiter at home and drive away until the motor and alarm in my plane go off. Thank you one more time for the info.
What throttle value be use for failsafe+RTH ? I bench test the failsafe+RTH procedure. It went well but I notice the throttle ramp up to 93% during failsafe+RTH. How to change that ? Because with that high throttle I doubt the plane will make it to home point.
RTH over water has saved me. What about when the UAV is in GPS waypoint mode? For example if the route triggers a fail safe will the route continue, if not is there a way to change failsafe in flight? Great channel btw !
Pretty nice, man! Thanks a lot! 😊 Only one tip: test the failsafe WITHOUT props. 😐 Because... I made that mistake and my quad scared the hell out of me. 😐
You can't say it too often! Remove your props while testing !!!! One of us has cut his fingers while changing vtx configuration via button 3 weeks ago. (And another reason using remote vtx configuration :) )
@@DroneMesh Pawel said many times that you should test your failsafe, but I think not one time that you have to remove your props before testing the failsafe. Yes everybody should know that, but I see enough people ignoring the fact that this can be dangerous for them and others. OK rth without props is .... :)
Pawel, can you give me some tips on RTH? I setup Inav on a 4'' quadcopter using the Matek gps with compass. Alt Hold and Pos Hold are working perfectly with no drift. The compass and accl are calibrated. When I execute RTH my quad starts toilet bowling, and although the home arrow points the correct direction, the quad is going the wrong way. I've checked the course heading, and all appears correct. If I change Mag Alignment, Pos Hold will toilet bowl. Could this be that I just need a better Mag Calibration? Very stuck on this problem.
So if it works either way, why is one way is better than another? Why is it preferable to hold last received values? To prevent fooling FC by "default" sbus values and triggering a disarm?
older versions of INAV had a trouble with signal loss near the max range that was connected with "no pulses" setting. With the current 2.0 it's no longer a problem but it's juts better to keep things as simple for FC as possible
I just got this Radio Master tx16s after 3 mouths, been using a flysky i6, thinking about sending it back. I have a pixhawk F.C. With a pixhawk and using Mission Planner. I put RTH on Ch.7 on 2 way switch. Got 4 modes on Ch 5 .Setup the failsafe on Ch7 with custom settings failsafe and add after two times on Ch5 on a 3 way switch one for the middle and at the end pointed down. do nothing for the one pointed up that will be for Ch 7 for RTH failsafe when you cut your Radio Off, simulating no pulses it interact with Ch 5 at 1500 on the second switch .Put the other two modes as stable on the second switch 1653 and 1802. When I cut my Radio off in Mission planner it says RTH and it switches to CH 5 on the second switch at 1500. My mode setup looks like this :PWM - Flight mode 1=1193, FM-2 =1326. FM-3= 1459 Number 2 switch Fight Mode number 5 = 1653, FM 6 = 1802 and ( FM 4 = 1500 when you cut off Radio RTH.) Hope this helps.
This is very interesting. I have all of my Taranis X9d+ set to No Pulses for all models and have had successful RTH on loss of signal fail-safes, including once when the battery fell out of the radio when I dropped accidentally. This is with when flying with iNav, with SBUS. I'll change them to Hold for the future.
Hummmm....has this disarm issue been fixed in 2.0.1 if the failsafe is set to "no pulse"? Or is the disarming issue solution to set the failsafe to "hold"?
so in resume: PWM, PPM to be set to no pulses, serial receivers like SBUS and Fport to be set to HOLD, crossfire do not have in my x9D screen any failsafe menu the menu is in the back of the fullside crossfire module and is set to cut.
Thank Pawel. I have iNav 2.0 and working on my first quad and have F4 FC set up for Ublox GPS. I have looked at many videos but none give specific detail on which modes/switch to set for GPS. Do you have a video for 2.0 thats shows the detail? Thanks
@@FPVUniversity Hi guys -Tahat is what i'm not sure about: I set hold on my Taranis -So should I also pres the button on RX to set Failsafe or just leave it?? Sorry for silly question but I want to be sure i'm new in fpv.Thank you for any answer Bob
that is a little complicated, right? and what if you change channel mappig but forget to update failsafe settings? I know a case when someone put by mistake RSSI on ARM channel. That was interesting
What about the failsafe setting when using FrSky Fport ? We are about to setting up our first Inav build and to spare uarts we decided to use the Fport protocol.
I think it doesn't matter. Because it is an extra information in the protocol it should also work if you have set your hold to arm an full throttle. There is a way to set the hold channel information for the receiver. Test it :) But remember to remove your props :)
Schon Richtig that isn’t hold...hold always sends the fc the receivers last stick positions before the failsafe occured...what your talking about is the custom failsafe setting, where you can set preconfigured commands that the rx will always give the fc when a failsafe occurs
Interesting! I use no pulses. Maybe an example with an oscilloscope would make it more clear for everyone. Is it possible to identify the failsafe signal with an oscilloscope?
Nice one again Pawel, can you explain for us noobs one more time, (more confirm) testing failsafe on the bench, if i switch off my transmitter and press fs button on my XM+ failsafe is set, in inav if all is connected, i turn off my TX the red parachute is lighting up, is this failsafe triggerd? Cause in olde inav i set my switch in failsafe, and angle mode, armed and 1600us throttle and pushed the fs button on my XM+ and than when i turned my tx off in inav all the sticks moved to the preset positions. If i do this in inav 2.01 the modes move to under 1000us instead of the presets. Bit confusing for me🙄 Ps this is with Hold and no pulses Thanks for the explanation
There’s no failsafe button on the xm+...your thinking of the bond button...all failsafe settings are done in the taranis radios, and are saved to the rx when you bind.
Frsky Qx 7, Frsky R9, Matek F405 Wing and inav 2.0. I also have been using No Pulses and RTH (test modes and turning off the transmitter) is working properly. Is there any advantage to using Hold if No Pulses is doing the job?
@@FPVUniversity Actually, if the ardupilot RC fail safe setting is Disable, the random (very low) signals will go through. Finally when auto landing on a remote location - if the land reposition is enabled - the copter will go crazy.
Dear mr. Pawel, Howcome that my vector fc (is sbus, taranis is set to no pulse) gives a green RTL in my screen (pc vector gui) if i switch off my taranis?
So my failsafe is ok than? I thought you said i have to use hold instead of no pulse? In my taranis i have no pulse and the vector goes in failsafe ok if i turn off my taranis
I'd like to have my RSSI channel set to 0% when there is no signal. Currently it reads 50% when the transmitter is off. In Betaflight I can go to the Failsafe tab and set the channel position to be HOLD (which is what is happening now in iNav, I see 50%), or to some value. I always set it to 0% so when the radio is off I see 0% instead of seeing 50% in iNav. Does anyone know how to do this in iNav configurator?
i cant get my l9r to failsafe. I've tried setting it from the RX that did nothing it just holds last position and i tired setting it in inav failsafe the drop/land they dont do anything either and when there activated the motor wont spin. Any ideas?
Crossfire do not have a menu on you x9d for failsafe, the menu is set in the module and is set to cut, at least mine full side crossfire module is like that, running version 2.2 on open tx, but I will doble check when I get home.
@@humbertomontalban3932 yes there is. you can use the crossfire LUA scripts to set it. in fact, if you have the micro module, that'st he only way to set it. I have the full module. but i can use either
@TryerFpv set the crossfire module (TX) to cut and you'll be fine. assuming you're using CRSF. The flight controller will see that failsafe bit hit your rth or w/e you have set for failsafe
Answer please the question, I want to understand Failsafe is the feature of receiver, not transmitter. Failsafe is a special state of receiver, while it detect link lost. So, why the transmitter (frsky) has failsafe settings (hold, custom, no pulse) My be, does transmitter send this setting to receiver? and receiver knows what to do while link will be lost
I always set my FS to "No Pulses"...Im guessing everyone does...?...Switching my TX to OFF results in FS Mode appearing in the OSD, invoking RTH. Hold, seems very unnatural, as traditionally, this is a Fixed set of parameters that programmes the receiver to go to and HOLD upon loss of carrier signal. This is what I find a bit weird about iNAV, they choose to make it more complex by NOT using RTH Mode as a pre-set Fail Safe position, like other Flight Control software does. 1) "No Pulses" set invokes RTH upon loss of TX signal. 2) "Hold" apparently also invokes RTH, (Not sure why it would TBH unless a HOLD pre-set was programmed as RTH Mode). 3) Switch to RTH Mode manually with the system working normally. 4) Switch to Failsafe Mode manually with the system working normally. Four different ways of doing the same activity....?....Yes, that's right, 4 ways...Confused yet?...you should be..lol. No Pulses okay for PPM....but not for SBUS....that requires Hold.....Why not use the FS built into every receiver?
EnglishTurbines I’m with you on this 100%! This seems odd to me. I use no pulse and when I turn radio off my wing goes into failsafe and does a RTH. Now he’s saying you have to use this hold!! Granted I’ve only tested this failsafe on the ground with no pulse and it seems to work now I’m not so sure!! I guess this just gives me one more reason to dump inav and just flash Chibios Arduplane on my boards and be done with all this craziness. Geezz😒
This is all this video is about - Hold is used only with SBUS (NOT PPM) cause SBUS/FPORT has a dedicated "FS" flag that is set in every failsafe mode (No pulses, Hold). 3 - RTH is not the same as FS (as explained FS behavior can be also land/drop) 4 - failsafe switch is usually only used for testing you dont have to use it. Why isnt RTH default - not everybody is using GPS for example. "Other" FS do have to have GPS.
@@kabturek thank you for saying that. I fly quads and among the quad community, almost no one fly's with a GPS module. It is pretty much just unheard of
In that case, the Failsafe scenarios on offer inside iNAV should be different Depending on which type of craft you choose......Less is more....Too many options.
Well, modern SBUS and No Pulses does work for me, he's saying now Hold is a bit safer. Im confident in iNAV it has worked flawlessly for me TBH...Different story using PPM as these scenarios are not possible, and he didn't cover us EZUHF users and PPM.
This is so wrong! Please change this video! Pos hold as failsafe is dangerous. If your GPS unit fails during a failsafe what will happen? Your wing will fly away. I have tested this multiply times with the same result in a fly away. Please correct your self and set to cut!!! It's the safest way!!
How often does your GPS fail?? If my GPS failed it would be because I'd had a total power failure (in which case the aircraft is going down anyway!) That said, I don't like the idea of position hold on failsafe. I want my wing to come home if the receiver goes out of range :-)
Chilternflyer it’s not position hold...it holds the last command you have the rx before the failsafe occurred...as far as Smokey saying what if your gps failed...well if your gps failed, your losing your plane whether you have hold or no pulse selected...inav has built in safe guards for gps glitch or failure that will force land the plane in such an occurrence.

Dear mr. Pawel,
Howcome that my vector fc (is sbus, taranis is set to no pulse) gives a green RTL in my screen (pc vector gui) if i switch off my taranis?
because it should? Failsafe is comunicated by a single flag. No pulses/hold only defines whet is sent from RX to FC together with failsafe flag
So my failsafe is ok than?

Failsafe is a special state of receiver, while it detect link lost.
So, why the transmitter (frsky) has failsafe settings (hold, custom, no pulse)
My be, does transmitter send this setting to receiver? and receiver knows what to do while link will be lost

Hold, seems very unnatural, as traditionally, this is a Fixed set of parameters that programmes the receiver to go to and HOLD upon loss of carrier signal.
This is what I find a bit weird about iNAV, they choose to make it more complex by NOT using RTH Mode as a pre-set Fail Safe position, like other Flight Control software does.
1) "No Pulses" set invokes RTH upon loss of TX signal.
2) "Hold" apparently also invokes RTH, (Not sure why it would TBH unless a HOLD pre-set was programmed as RTH Mode).
3) Switch to RTH Mode manually with the system working normally.
4) Switch to Failsafe Mode manually with the system working normally.
Four different ways of doing the same activity....?....Yes, that's right, 4 ways...Confused yet?...you should be..lol.
No Pulses okay for PPM....but not for SBUS....that requires Hold.....Why not use the FS built into every receiver?
EnglishTurbines I’m with you on this 100%! This seems odd to me. I use no pulse and when I turn radio off my wing goes into failsafe and does a RTH. Now he’s saying you have to use this hold!! Granted I’ve only tested this failsafe on the ground with no pulse and it seems to work now I’m not so sure!!
I guess this just gives me one more reason to dump inav and just flash Chibios Arduplane on my boards and be done with all this craziness. Geezz😒
This is all this video is about - Hold is used only with SBUS (NOT PPM) cause SBUS/FPORT has a dedicated "FS" flag that is set in every failsafe mode (No pulses, Hold).
3 - RTH is not the same as FS (as explained FS behavior can be also land/drop)
4 - failsafe switch is usually only used for testing you dont have to use it.
Why isnt RTH default - not everybody is using GPS for example. "Other" FS do have to have GPS.
@@kabturek thank you for saying that.
I fly quads and among the quad community, almost no one fly's with a GPS module. It is pretty much just unheard of
In that case, the Failsafe scenarios on offer inside iNAV should be different Depending on which type of craft you choose......Less is more....Too many options.
Well, modern SBUS and No Pulses does work for me, he's saying now Hold is a bit safer. Im confident in iNAV it has worked flawlessly for me TBH...Different story using PPM as these scenarios are not possible, and he didn't cover us EZUHF users and PPM.
Should i set no pulses or hold for crossfire??
you can not set that on you radio, has to be in the module of cxf to cut.
This is so wrong! Please change this video! Pos hold as failsafe is dangerous. If your GPS unit fails during a failsafe what will happen?
Your wing will fly away. I have tested this multiply times with the same result in a fly away. Please correct your self and set to cut!!! It's the safest way!!
How often does your GPS fail?? If my GPS failed it would be because I'd had a total power failure (in which case the aircraft is going down anyway!) That said, I don't like the idea of position hold on failsafe. I want my wing to come home if the receiver goes out of range :-)
Chilternflyer it’s not position hold...it holds the last command you have the rx before the failsafe occurred...as far as Smokey saying what if your gps failed...well if your gps failed, your losing your plane whether you have hold or no pulse selected...inav has built in safe guards for gps glitch or failure that will force land the plane in such an occurrence.
