f550 not very stable

[heliuser]

Hello everyone,
i´ve having a problem about being able to keep the flight stable in the same point. The video below shows the issue. I can´t make it stay flight but still it looks like its always ajusting the position. One thing i noticed is that the gps shows the green light but when its on the air the green light changes to a blink red. Any tips?

Thanks a lot

doesnt look so bad. try flying out of gps mode. raise the gains. try flying in a different spot to make sure its not interference. most likely a gains issue.

Thanks, will check that

Something's wrong if you're taking off in GPS and the LED starts flashing red.
Something's really wrong if your video was what happened when you told you told your F550 to do a GPS hover and then only took control when you landed.

Had you successfully flown in that spot before?

It was the first time. Now after adjust gains, its much more stable . On the video i´m always on control , but the first part of the video is the hovering that was shaking. About the led still checking it.

Just a thought

Check one thing! If your Naza assistant is showing hexa rotor I, you will get these symptoms. Switch to hexa rotor v and it should be fine.....
mine was behaving the same - it's now perfect

Flashing red usually means low voltage, what packs are you you, where is you low voltage alarm set?

Pete has a point about the flashing red light. I've noticed that mine is stable in GPS most of the time but not all time. When I fly in my usual spot the building can block out the GPS satellite signal and then it becomes unstable, switch to att mode and it will behave. Sometimes it will give a twitch when it finds another satellite to lock on when it loses the signal from the one it's on. Just my experience that's all.

Hey Pete what is a good voltage for the low voltage alarm or should I leave it at default?

Flashing red usually means low voltage, what packs are you you, where is you low voltage alarm set?

At the moment i don´t have low voltage alarm configured. I using a gens ace 3s 5000. This Red light its right after start even when the battery is full. I´m going to try to film it to show.

OK, a couple of observations. The height you're hovering in is barely out of "ground effect" and you're going to have a lot of turbulent air which will be made even worse due to the height and proximity of the fences and the building you're flying near. Also, I'm assuming you're using the Naza? The GPS on the Naza is a little less forgiving when compared to the Wookong-M (from experience) and it can struggle to get a decent GPS lock on more than 5 satellites in a built up area, particularly in your back yard with fences like you have - my F450 with Naza behaves similarly with just 5 satellites. Go out to a more open space, let it get a full compliment of satellites to lock onto before you take off (no flashing red lights and wait for a nice stream of green lights indicating that it's remembered home) and get at least 5 foot off the floor - I think you'll find it behaves quite differently.
