Thanks for the comments on how negative number's work ;) I'm aware, but please keep in mind that I've tried to explain it in a way that would make sense to the majority of viewers and included the graphics to remove any confusion. Happy flying!

Excellent Video! Yesterday I lost my ZOHD Drift in a field with tall grass and could not find it for 20 minutes. Then I remembered that I might use signal strength and watched your video on my phone to see how to do it. At first I walked past my plane several times because I assumed that I would see a number close to -25 db near the plane, but with -65 db I was almost on top of it already. Holding my TX antenna to the RX I get about -27 db. So thank you very much for helping me recovering my plane!

Genius. Unfortunately I watched it AFTER I need this. I'm prepared for the next time. Thank you very much 👍🏻

Did the same with FrSky and FlySky radios a while ago. This finding method indeed works. Still it is good to have a buzzer in your model. And even better - with batttery backup, because batteries may detach. Racing/freestyle pilots will understand.

lost a toothpick in salt marsh, loose power lead on the VTX meant I had little idea where it came down and it had the quietest becon sound and in the windy conditions it may as well not been on. Genuinely thought I’d never see it again. The ELRS signal strength telemetry saved me… although it took me a few minutes of wandering around in panic before I figured out I could use it to get a zero on where the quad was. Very useful!! Also I had no idea if it would work or not but I wandered away from the area I thought the drone was until RSSI bottomed out and then did my first spin, then realised it may just work.

@Painless360 11 месяцев назад

Seeing that you still have telemetry is always a relief. Our best recovery of a 'wayward' model was almost 2 miles away using this method!

@TechnicallyTom 11 месяцев назад

You can also check for the weakest signal by pointing the null of the antenna where you want to check. That works better sometimes. I have GPS as well as a self powered buzzer. Also just got the mandatory RID module and suppose that might come in handy for finding a downed model as well.

Thanks!! Love ExpressLRS!! Converted all my fpv drones to ExpressLRS and this trick is great!

@ramonsmithnz 11 месяцев назад

I love your channel!!! Been subscribed for a few years now, and have used it so often from my wings to my quads, love the way you deliver your content, and your message...I now mainly buy from a local store if I can just to help because of you!!! Keep up the great work!! 😊

@ellingolsen3194 11 месяцев назад

Yes, I have done this! Lost my quad in a large field of dense grass, bushes and thorny things. I got close but still could not see it. In addition I had a very loud beeper on the pre-arm switch. The kind of beeper that must also be connected to 5V power. Afterwards I could hardly believe how easy it was.

@bulufish8208 11 месяцев назад

A simple solution 👌 thanks 😊

@dayworkhard 11 месяцев назад

I have used this 8 years ago by setting up a switch on my x9d plus radio which can be pressed to play the sound for RSSI in db so that I would know which direction I should go in search for my drone in the field. 😊

@charleswatt4397 11 месяцев назад

Keep in mind that you can have dynamic power set in ELRS and that can confuse this method.

@tubamanandy2 11 месяцев назад

Agreed, numbers will change with different power levels but if you still walk in direction of lowest value (strongest signal) you should still find your model ?

@cyclops-fpv 11 месяцев назад

I've used this system but I've also spun up the motors too as a way of finding it as long as they are able to spin up freely(for a few moments only).

@CapungPlastik 11 месяцев назад

Long while ago based on DIY ELRS TX using ESP32 I make somekind of bird tracker (tracking RX position) using the same method. Add some buttons, oled and buzzer for setting & notification. while for the RX I'm using the Matek PWM RX and add buzzer on a channel to locate the bird if we're close enough.... 😄

@jaysonrees738 11 месяцев назад

I've been using GPS telemetry to find my way to lost models. Can put the coordinates into my phone and it'll usually get me close enough for the beeper. It saved my Dolphin after the motor burned and it "landed" in a corn field. With some GPS models costing as little as $15, they're just going to go on anything with a spot for one.

@baggszilla 11 месяцев назад

@ewaldwasscher7251 11 месяцев назад

You had me confused here. To me the lowest number is the number that is most negative. So with all RSSi values on the radio being negative, -100 is lower than -50. I realize that it's different from FrSky, so we'll done that you took the effort to explain it.

@pavlobalandin1021 11 месяцев назад

@z2kk 11 месяцев назад

Pair this technique up with a gyro and radio manufacturers could have a great built in feature.

@jeffbluejets2626 2 дня назад

Would you have any idea on range one could expect from a grounded model given initially the much larger using expressLRS?

@Painless360 2 дня назад

Depends on lots of factors but about 300m is something I see a lot... Happy flying

@Catiadr 11 месяцев назад

Perhaps a lua script could display an arrow based on this feedback? I don't know what graphics libraries are available. I did this once by connecting my cell phone to my go pro and once I found the camera, I searched in increasing radius for the drone that had rejected the battery and the camera on impact.

@Painless360 11 месяцев назад

There is a LUA script already (see link in description) but the idea of it storing the values and heading, like the motion tracker in ALIENS, is a great idea!

@TheWingnut58 11 месяцев назад

Just got myself a Radiomaster Pocket (total newbie to erls), will this work with this radio?.....is there a specific receiver that I have to have, or must I have a FC?

@Painless360 11 месяцев назад

No, all radios will work. ExpressLRS always sends back RSSI data. Best of luck

how to get that detail telemetry in radio? I have enabled telemetry in receiver tab betaflight but in radio only show battery and time when i press telemetry button in radio

Select 'Discover Sensors' in the telemetry tab, they should appear. Best of luck!
