Betaflight Rescue Mode (BF4.4) - Using Switch and Activated by Failsafe. Auto Landing like DJI Drone 

Thnx for all the help you hand out. I did try this today only to smash my airunits cam. I did do the settings like your webpage says. (just not the hold set throttle and yaw pitch roll) So what happend was from 1,5 to 2M of altitude and a fix of 9 to 10 sats It dropped on the gras for a second. then went up in the air and came back home. I tested mine with the radio turned off. I turned my radio back on and my crossfire went to 2:100 so a perfect connection. I then deflicted the sticks.... but nothing happend... tried again... ( I knew about the 30%) So then it just flew home I tried a quick disarm and arm.. but still just fly back home into RX lost... and right before it was home it just failsaved and crashed in the pavement smashing the cam. :( but My head can't get around why it would not regain controll.. Eventough the connection was mint. any toughts ? no blackbox files unfortunatly.

Yup, just practicing my wing skills again after about 2 years :D

@@OscarLiang1 Nice! Keep it up!

we are getting closer to owning a DJI drone day by day LOL

Maybe not enough sats on your way home?

Just use a good omni directional antenna from a reputable brand, here are my recommendations: oscarliang.com/best-fpv-antenna/#Omni-Antennas-Best-Value

you can do either. but you must take off after you have a solid satellite fix if you want to test it.

please check the link in video description where i explain each settings.

i can see so many people are gonna abuse rescue mode just because they are feeling lazy to fly the quad home XD

@@OscarLiang1 lol and ...oh look hunny watch this ,this is sooooo freakkkkking cool ! ........smash 🤕

yes, you need a gps on the drone. i have a beginners guide here if you are totally new to FPV drones: oscarliang.com/fpv-drone-guide/

Nah, freestyle shouldn't be an issue for sats. as long as you mostly fly under open sky and not inside a building

It keeps coming toward you when set up right. After you lose both connections, just sit down and be patient and keep looking up. It will land close enough to you.

Rescue mode should still be on until you manually terminate it. Quoting wiki: the pilot must move the sticks more than 30% to regain control after the radio link comes back after a real failsafe

set it to cut, and let Betaflight handle failsafe

@@OscarLiang1 thank you for the fast answer you are doing great work

Sometimes, if you take off and spin around during arming or immediately on takeoff, the quad’s attitude information can become corrupted, and the Home Arrow can point the wrong way. It’s best to arm cleanly and fly away from Home in a straight line at a reasonable speed immediately after takeoff. Watch the Home Arrow carefully to ensure it quickly points back to Home. If the Home Arrow points the wrong way when a failsafe occurs, the GPS Rescue will initially fly off in the wrong direction, and in some cases, you may lose the quad.

@@OscarLiang1 I see. But in my case, the wtof osd arrow is pointing reversed while the dji osd is correct. I put them on at the same time, I see them both on my goggles

The wiki explains how the new sanity check works: github.com/betaflight/betaflight/pull/11579

What do you mean?

@@OscarLiang1 where does the writing in your OSD come from?

just download it from github and put them in the goggles :) i show how to do here: oscarliang.com/fpv-wtf-dji-goggles-osd/#Custom-Font

@@OscarLiang1 Hmmm, "Nov 2022 - added instructions on how to change font". Looks like in older versions of the fonts it was "km/h" but was changed to "kph" later. I need to check that as "kph" kills my eyes :P Thanks!

@@rfly-fpv oh, that's the last update you see? I updated the guide last night with links to those color fonts, maybe you need to clear the browser cache (press CTRL + F5). Anyway I downloaded those font here: sites.google.com/view/sneaky-fpv/home

@@OscarLiang1 No no, I just posted the date when you started playing with fonts and thought that you see "km/h" only because back then (in Nov 2022) it was like that in the older version of the SneakyFPV fonts ;) I see the most recent article without clearing the cache - all is fine :)

@@rfly-fpv ah i see, I am using the latest Sneaky Conthrax font if that helps :) i am gonna make like a screenshot comparison of all the color fonts this afternoon

See last link in video description :)

@@OscarLiang1 Saw it after typing. 😂 Copied the fonts in the SD card root, still they don’t show up. Also if I don’t boot the goggles first, the OSD is not HD and all off center.

probably the flight controller trying to adjust attitube while landing.

@@kithng yeah I get that. But it doesn't seem normal 🤣

just my theory - it's a form of warning if there are people below the quad. also i think altitude isn't updating fast enough so it's descending little by little

@@OscarLiang1 that is a nice interpretation for that " FeAtuRe" :D

when failsafe is triggered you will see RXLOSS on screen. also you see RESC in OSD when it's flying home.

@@OscarLiang1 did you use the BF standard "RTH" settings?

@@1stslave143 I am not sure what you mean by RTH, it's just Rescue mode in Betaflight.

Nobody cares

@@sten6537 awesome 👍😎

@@transient-sight9692 I care :D

@@OscarLiang1 i know, my good man 👍
