failsafe setup with Flysky X6B I-bus / PPM

Hello,
I need some help to set up failsafe with X6B receiver.
My X210 is almost ready to fly, failsafe is enabled in Betaflight but when I test the failsafe it doesn't work. After switching off the DEVO, motors are still spinning the same speed and don't stop so...no failsafe. Failsafe on X6B works only in PWM, I'm using I-Bus port.
I'd like to know the way to set this in deviation, had a look to the manual but I don't really understand how it works and which value to enter on which channels of the mixer.

Yes failsave it works on ibus, but you have to configure failsave settings in each configuration per channel.

I would really like to have a set failsave, in protocol option just press a button and. Store allsticks and pots as the failsave.

Hi. How did you get the x6b working with deviation? Is it plug and play. Just pick protocol Flysky afhds2a and bind??

Yes,very easy to bind with Devo 10 and 4in1 module. Finally I have set the failsafe for every channels in the DEVO but motors do not stop, they just decrease speed to min throttle, I'm still working on this.

Model menu > 2 Mixer > 3 Throttle > Failsave -125
Each channel has it's own failsave setting.

The props spinning at minimum sounds like a betaflight setting, not deviation. Some FC software only stops the props when you disarm, because if the props aren't spinning you have no orientation control. But I'm not familiar with betaflight details, so maybe not.

And how is this stored on the receiver? Which procedure?

I have no idea .....But after setting Failsave as described above, when switching off the TX, the RX went to this value.
Before when nothing entered (just default setting for failsave), it kept the last received value, basically quad will keep the motors powered......

For me it would make some sense, to have a store/set failsave button (or any failsave option) in the protocol options menu, basically set all sticks pots in designated position press failsave store button.

But anyway at least failsave works as way currently implemented AFHDS 2A, ibus to Betaflight.

...In other words, the receiver takes these setting into the memory? Did not find this in the manual.

But if not, all these settings on the transmitter are not important to the flightcontroller.

When it takes the last input as valid, you crash or will have a fly-away. The receiver must have an assigned channel on which a predicted value can be triggered in case of connection loss. Otherwise it will not work, at least on multirotors. Values below min throttle or no pulse are ok..
Anyways, on the first four channels the FC is the ruler...

Probably failsave value is sent over the link via afhds 2a protocol from Tx to Rx. Anyway failsave works fine for me and can be set to value of choice.

When failsafe is activated, how can the tx send a value to the rx since theres no connection anymore. The values should be stored on the rx. How did you set Failsafe in Deviation? Can you please explain to me Any help is appreciated.

Thank You

Failsafe values are a property of the Rx, not the Tx. You need to set them on the Rx. This is normally done by setting the controls on the Tx so you get the values you want to use for Failsafe sent to the Rx, then doing something to tell the Rx to store those values. Could be binding, could be pushing a "failsafe" button, could be powering on with a button held or a jumper installed or some such. Some protocols have a way to send "Failsafe" packets to the Tx to set them instead. Deviation uses the failsafe values in the channel settings for those packets, and in other protocols if the values are set at some specific point, like binding or connection.

Do the props stop if you throttle all the way down without triggering the failsafe? If not, then the problem could be the minimum throttle setting on the FC. Some of them don't like to spin the throttles all the way down unless you shut things down.

failsafe is set only on the TX, check also this topic

You sir are a legend!!!!!

Been trying to get this sorted out all day going through every option in Betaflight.

Still not sure how the quad knows to shut down when the failsafe is set from the transmitter that its supposedly lost signal too but hey, it works.
