BETAFLIGHT - GPS RESCUE 4.4.1 PROBLEMS AND HOW TO FIX!

If you have the same betaflight 4.4.1 gps return to home issue... then try this! It's the only single thing I changed, and it worked!
tbs m8.2 gps module
aos 3.5 quad
dji v2 goggles
tango 2

That was really cool.... and fun !

[@PhillyDroneLife]

Love it mate. Thx Budd.... Mikey

[@oneguysview1430]

New sub here. Thanks for all the info.

[@SkeezyFPV]

I’m really wanting to put a gps on my 5”. And my 2.5” lol. Great vid!

[@FPV-TV419]

Thanks dude. 😁. Yea id do gps on anything that I can get it on! Even if it's a 90% chance of it coming back its worth it all day long!

[@SkeezyFPV]

@@FPV-TV419 it just seems like something fun to mess around with and the units are pretty cheap. I’d love to have a reliable rth on my quads. I’d feel a lot better about flying them over water.

[@pilotpen2255]

hii.. i have maybe same problem or not, my gps work find but went my quad go to my home position he go down after 2m on air he disarm auto and drop.. how its work like this..😊

[@phiveone]

Looks good! Share screenies of your GPS settings?

[@FPV-TV419]

The gps settings really are dependant on what your flying, where your flying etc. The settings required to make it work are better explained on other channels like Joshua Bardwell etc, if you trying to set it up for the first time, I'd go have a look at his videos 👌

[@Chillin-fpv]

So am I able to put failsafe and gps rescue RTH mode on the same 3 position switch? First position is off / nothing. Second position is failsafe and third RTH?

[@Chillin-fpv]

Lol what I thinking back then lol.

[@craigdavidson52]

Thanks, will chat ge my rate as I had erratic behavior!

[@FPV-TV419]

Let me know if it fixed it for you.... thats the only thing I changed and it fixed it for me.

[@mccartikiss]

Can you interupt the return to home and take control again? Like with a Dji drone...

[@FPV-TV419]

Hi, yes u can. Just un press the rth switch, and it will be back in your control

[@dburke4]

@@FPV-TV419 hi mate what If it’s a real failsafe and you didn’t flip a switch, how do you get control back ?

[@gregorenz1437]

Yes Work nicely

[@gregor.potrebujes]

@@dburke4 you move the sticks for at least 30% or so... something like that. And don't ever move the throttle to 0% while rescue is active, because it will disarm.

[@mikeyama7277]

Mine drops like 5 meters before going up, what could be the reason of this? its useless like this.

[@kingsleyao7033]

Change your throttle to set on stage 1 and add 5% on hover throttle and put this value in there. Example if your hover throttle is 1300 then plus 5% is 1350 put this in your stage 1 throttle set value. This should ensure you your quad will climb and not drop in stage 1 which is 1.5sec before stage 2.

[@misturarica7519]

You know for how long someone has not flown by how much they shake :D

[@goonbreathfpv]

My gps rescue does a similar thing. Erratic behaviour. I changed angle from 70 to 30. Also the gps rescue has its down pid for throttle. It was at p=150 by default so I set to p=50. I will try what you said here about gps baud rate.

[@jeffclassics]

Hi Dan, the also suspect that the separate pid (actually hidden) of the gps causes the pitching. It's so annoying. I had 4.2 working perfectly especially after it rotates 180.now, the nosing is very sketchy af

[@trebor1477]

Yes this is correct. I had the same value of p=150.

[@goonbreathfpv]

@Trebor my issue was not fixed. Also one time it disarmed about 80m in the air and nearly hit me. I don't wanna do that again!

[@trebor1477]

Problematic settings when drone did not want to land an did disarm in the air on same altitude he came back set gps_rescue_throttle_p = 150 set gps_rescue_throttle_i = 20 set gps_rescue_throttle_d = 50 set gps_rescue_velocity_p = 80 set gps_rescue_velocity_i = 20 set gps_rescue_velocity_d = 15 set gps_rescue_yaw_p = 40

[@goonbreathfpv]

@@trebor1477 so what settings do you use now please?

[@Les_Grossman]

Thanks for the video but you REALLY should mount your RX antenna differently!

[@FPV-TV419]

For what reason??

[@softart5235]

could a drone return home without baro?

[@borisdamole]

From betaflight docs: If a Baro is present, enabling it will improve IMU altitude estimations significantly. We recommend enabling Baro by default, especially for short flights (eg up to 10-15min). Usually this results in better altitude control and more reliable landings. Check the baro data in the sensors tab after enabling the ALTITUDE debug. It should be reasonably smooth after arming. Whether or not Baro is helpful is readily seen by doing some LOS rescues at low altitude over flat ground. For longer flights, and some Baro hardware, Baro drift can be more of a problem than GPS drift. Hence do some testing with it on or off and then set your Baro trust value appropriately for the kind of flying you intend to do

[@rgglenn150]

so setting the baud rate fixed it?

[@FPV-TV419]

It did for me yes.. but it might depend what gps unit your using. Mine was the tbs m8.2

[@renerjose4753]

@@FPV-TV419 very informative presentation sir! if setting to max baud rate fixed your erratic rth flight issue, what is the default stock baud rate for the TBS M8.2? cheers!

[@rgglenn150]

@@FPV-TV419 i just installed it today. sad to say everything works but it disarms about 10 feet during landing

[@rgglenn150]

I might be downgrading to 4.4.0

[@renerjose4753]

@@rgglenn150 so i assume the quad returns to home as intended? but disarms at a height of 10 feet when it arrives? if so, are you getting accurate altitude indication from either gps or FC? you may also want to check this altitude setting option in BF4.4.1 to be sure.

what props are you using ?

Hq dt90 cinewhoop props. I tried some others too, but these fly great! And very quiet!

@@FPV-TV419 really? what flight times you have ? and how many mAh is your batt ?

[@waynegoldpig2220]

Hey bud, there's a few more settings you need to get right. This guy explains it: kzbin.info/www/bejne/q56ul4WFp71jl6c

[@FPV-TV419]

Hi mate. Yea all my other settings are correct. You don't always need to set throttle to a value in the failsafe tab. Mines set to auto and works just fine. All other settings are as you would usually set up gps rescue in bf.... its just the baud rate that was too slow, and this has to be manually set on mine. Some gps modules may auto set at a fast enough baud rate. But mine didn't. It works perfectly now 👌. I've done a fair few tests and it's been solidly reliable so far. The auto land is a potentially useful feature, but usually you only want to rescue the quad back to where you can retake control
