Betaflight GPS Rescue Configuration (my best settings)

---

Let's go through Betaflight GPS Rescue configuration and I'll show you my best settings, as well as explain what all the settings do and which ones you might want to change.

How to wire up GPS and configure Betaflight to use the GPS:

[FPV]

One thing to consider (what I do on all my GPS quads) is set the aux for the flight mode in the channel fallback to angle mode. So when the first failsafe stage triggers, it puts the quad upright and sets the antenna in the most optimal position and most likely regain rc link and prevents the second stage to trigger.

Wish my teachers in college were this good.Thank you!

Just a little tip. I was working with getting GPS rescue to work on one of my quads, using the Radiomaster Zorro as my controller. The G and H momentary buttons on the bottom of the controller are perfect for this. I set the G button to activate "failsafe" when pressed, and the H button to activate "GPS rescue". This worked great. When I pressed and held the right button (H) the quad would execute the return to home sequence, and when released the quad returns to manual control. The left button (G), when held for longer than the threshold time, initiates a failsafe. The quad switches to "GPS rescue" and begins to return to home. It continues in GPS rescue mode until you take over and move the sticks.

I just finished my first 5 inch build thank you so much Joshua Bardwell your videos were so helpful could not have built it without your videos also i used your ESC and flight controller thank you man

Hi Joshua, manual switching turn off GPS rescue isn't necessary for freestyle or bando, because there is gps_rescue_min_dth parameter. I set this parameter higher (over my freestyle distance) and GPS rescue is ready for long range flight only. For short distance there is drop mode only (under min_dth).
BTW: Many thanks for you job. Greetings from Czech republic.

Thanks a lot for making this. On the fence about buying a Flywoo Explorer and this pretty much sealed the deal by helping me wrap my head around this FPV kind of GPS rescue.

Joshua, you are a FPV tutorial dream my friend. My quad fell from the sky while testing the GPS Rescue mode the first two times. I think you just solved my issue with Sanity Checks....but now its too dark and too late to try it. Fingers crossed 🤞

You can activate or deactivate GPS rescue through the OSD display on your goggles.
Set it like setting up smartaudio.
Adjust your failsafe settings to suit your flying environment.
I am using BF 4.2.2.

Just want to say thanks JB! First FS today, thanks to this video I still have my bird. Worked perfect!

I think you’ve just found the perfect workaround for being able to fly freestyle with gps rescue temporarily disabled. At 4:33. Enable allow arming without fix. If you’re only going to do some freestyle then arm your quad as soon as you plug the battery, that way you won’t have 8 satellites for sure and gps rescue is disabled for the whole session (yeah of course if you disarm and in the meantime you got 8 or more sats then when you arm, gps rescue will be enabled). On the other hand, if you’re flying long range plug your battery and wait for 8 satellites before arming, this way gps rescue is enabled. :))

Just starting in this hobby and I have to tell you your presentations on the channel are top drawer. About to build my first FPV Drone and without your channel it would be a lot harder. Well done Josh keep it up.

Hi Josh Great new video on GPS. I have just finished watching your video on GPS you did two years ago and I am finally figuring out INAV and RTH, but I didn't know what Betaflight was doing. I just purchased the Flywoo Explorer and was looking for some videos on how to set it up. Thanks for the remake.

Missing 2 things in this video

When gps rescue is active and at the time your back in control, you need to imput at least 30% stick movement to get out of gps rescue.

And for the people using li ion packs, you really want to set your max trottle lower. Good chance that you will pull to much amps and kill your pack.

[MadRC]

This is such a good video. I refer back to it from time to time as there is some quirks to Rescue I always forget.

[gmivisualsjason]

Was just thinking... and please correct me if I am wrong. (I'm not the sharpest tool in the box) if we lose rx signal and the gps failsafe kicks in and we have selected "yes" to sanity checks either it will return or fall to the sky.

With control links such as CRSF it's more likely that we will lose video before we lose RX. So when this happens we have to manually activate gps rth.
If this happens when we have selected "failsafe only" as you suggest then the Kwad will either return to home or simply keep flying. If the latter occurs then at the point our video fails we may be able to get the gps coordinates but they could be very wrong as the Kwad could be still flying and eventually land along way from the gps coordinates.

Therefore I believe the safest option to be to set "yes" to sanity checks! Either it will fly home of fall straight to the ground directly where the gps coordinates in our osd indicate.

[twinturbostang]

Very good. The one thing missing though is which failsafe approach to use in the receiver. You can set it to activate GPS Rescue mode on failsafe via aux channel position. Or.. set the receiver to "cut" all channel outputs which then triggers GPS Rescue at the flight controller. The preferred method may be debatable. But setting the receiver to "cut" might be the safest option.

Great video. I’ve been slowly taking my DJI FPV 4” to it’s range limits now that I have a reliable GPS unit installed, the iFlight unit. My previous TBS M8 unit sometimes would get a lock in about a minute and other days I could fly for 20+ minutes and never get a single satellite even on a clear day.

[devilidol]

Cant you change the failsafe settings in your OSD? I've always seen the failsafe option in the OSD.

[CesiumSalami]

In 4.3 - "current altitude" will include a configurable buffer. Like "current altitude + x meters" which I really think most people will want. Like, current + 35-50m (although the default is 15m). Mid/long range you just can't go too far behind obstacles before blackout, so ... i really think 95% of the time this would be the option instead of max alt.

Thanks, Joshua, very in time! I am just planning to fly away on my flywoo explorer
