Also that did make my rssi go up to 90% !!! You must have been doin this for a while lol your solving weeks worth of probs that I have had in minutes

That's great news  A lot of issues are usually easily solved via configuration if you know what settings to tweak/change.

And yes, the R-XSR supports redundancy if you want to set that up and it doesn't require any extra hardware other than the two receivers themselves. But TBH I probably wouldn't bother on a short range mini quad where the receivers and antennas are going to be close to each other anyway, whereas on a plane/wing you have the space to add some decent separation for the receivers/antennas on either end of the wings.

This is how you would wire up an XM+ and R-XSR for redundancy...

Ok so let’s say I did try to do the redundancy feature how do I know if I have enough power to distribute for both of them? I am not runnaing anything except the basics ... camera vtx, motors etc... but I read somewhere on my fc instructions that I could only have so much power drawn from my fc at once ... or how would I meter the draw of everything to make sure I don’t exceed that limit? I only have the one camer and I would like a run cam as well but what I am really wanting is a gps of some sort and the lost beacon sound as ons which I know would need more power as well.... is there a way to add another pdb or something? And sorry I just have so many questions lol very eager to learn it all but I cannot get the static noise to get out of my audio when I record audio as well... I love the sound of the motors just getting in it when I watch videos of other people and the sound is great quality with no static noise ... and I dont know how this into fpv works but is there a way for me to show my appreciation for your help ? Because I will give u the best there is if it’s possible.. thanks again !

Most FC have dedicated pads for all the necessary components you need. If you are very worry about overloading the regulator, you can always use a digital multimeter to measure the current draw. Most of us do not worry too much about the amp draw as long as we wire things to what the manufacturer suggest.

Receiver amp draw is usually very minimal. So a second redundant receiver should still be fine.

So I flew today finally!! But I don’t understand what’s going wrong because every indicator or warnings were perfectly fine I had around 90 % rssi and everything appears great but after about 3 min into the flight my quad just quit responding to anything and just kinda drifted for a couple seconds then dropped about 120 ft or so on to someone’s house:/ again I was in a open flat area and maybe 300 ft or so away from where I was standing... easily within direct site.. it broke an arm and somehow the sd card slot so I can’t look at the black box log. When I returned to my laptop I plugged it up to my fc and my receiver would act accordingly as far as LED indicators but when I don’t have a cable plugged into it just the battery the receiver acts like it has no pwr at all? Kinda doesn’t make sense to me but have you heard of this before ?

If your quad appears to lock up, drifts for a couple of seconds, and then drops, a failsafe condition has kicked in. For comparison, you can see the same at about 2:20 into one of my videos in another post HERE.

It's unfortunate that you don't have blackbox logs because that would have helped try and understand the sequence of events that happened. Do you have any DVR of the flight you can post because that can also sometimes shed a bit of light?

Failures like this are a good reason why you shouldn't really fly over houses or people where there is the potential for someone could get hurt by a falling quad, or for someone's property to get damaged. So just something to keep in mind because we're already under heavy fire from over-regulation in this hobby and the public generally hate drone pilots.

If you're getting no power with just the LiPo plugged in then it sounds like you may have fried the 5V regulator on the FC which could be a cause of the failsafe or something that happened as the result of a crash, but if you didn't lose DVR when it dropped then it is probably the latter. Do any LEDs light up on the FC itself when just a LiPo is plugged in?

It is hard to say what happened. You can download the content of the SD card through the USB connection. Maybe the blackbox will reveal something.

Is it possible to update r-xsr with jumper t16? If not any other way without taranis?

I can't be sure that this will work, because I don't have this radio.  But the Jumper T16 has the JR bay.  since you can push firmware update to a module, you should be able to push firmware to a receiver.  the bottom pin in the bay should be the S.port pin. You will setup a wire harness like you would do on the Taranis X9D plus and tell the Jumper to update the external module when you have the receiver wire up.  I used to update my receiver with my Turnigy 9XR Pro like this.

Yea I repinned my harness and got the firmware on the sd card I see it in the t16 but I dont see the option to flashit I can only copy or delete the file dont see how to initiate the flash.

If you have the SmartPort wire connected from the R-XSR to your flight controller, you can use FC passthrough to flash it...

Maybe Oscar or sloscotty will chime in. They both have this radio.

I did this step by step with no luck. Bardwell Said in his video to remove receiver power wire but ill leave this for another time i have it working for what i need right now dont really need the extra uart pad.

The other way to do it is to get an FrSky STK Tool and flash the R-XSR directly from your computer using that...
