Interference help. Flight review

[flabombarda]

Guys,

Today I tried to fly in a region I fly at least once a week. It is IN the city, so interference is normal, and expected.
However today was almost impossible to fly.
- I was unable to get clear video, not even for a second.
- Did not lose signal on the remote, in fact the remote had 90% of the time full bars of signal for both controller and video.

The quality was so bad that I returned and landed
Below you can see the flight log on airdata.com

Is there any recommendation/setting to reduce this ?

Yesterday on a different location I got 2.8Km distance on a straight line, so it is not a hw problem.

thanks

I'm seeing a significant amount of interference. It could be Wifi or radio interference, maybe even a cell phone tower.

Crap. Either there is a lot of signal interference (in one of the most populous cities in the world) or there is something wrong with your system.
The state assembly building is there. Tourists with a gazillion phones. Buildings to the northwest....

Fly somewhere else.

It really is that simple, you have to understand this kind of location is going to give you massive issues.

Mobile phones
Cell towers
Wireless broadband
Wireless CCTV
Wireless Burglar alarms
Any and every kind of wireless home automation system.

Anything else that decides it's going to be there on that day


All of these will by tying to use the 2.4ghz licence free band that your craft is also trying to use.

****, how did you pull out these values?

Go to sensors.

 

[Cyberpower678]

Go to sensors.

And then what? I want to know how he flew to get such battery efficiency. Only 19% drop after 10 minutes? Is this a modded drone?

 

[HFMan]

I was wondering the same thing... don't see how a stock battery can do that.

 

[AlanTheBeast]

I'd say there's an error somewhere with the data or the airdata algorithm:

Here is a "normalish" result from one of my flights:



Here is his. 7 hours. 48 miles.



So I'd chalk this up to error and not a miraculous mod. And the error in the data may have something to do with all the interference.

Unlikely. He only used 19% battery in ten minutes. With that he can fly another 30 minutes at the same rate and still have 22% battery left.

 

[Qoncussion]

For the sake of troubleshooting this, you need to try and fly somewhere outside of the city. If it's still buggy, that will tell us something, like there is a problem with the drone. If it's not buggy, that will confirm signal interference (kinda).

Did you look at what I posted? Reporting that he had 7 hours and 48 miles of battery. Data error and/or algorithm error IMO.

That 19% is probably just as bogus.

I did, but I highly doubt the landing battery value is bogus. And given your recent slip, not your fault I know, on another thread...

Seriously though, if we want to find out. Let's have a look at the original TXT.

@flabombarda can you upload the original TXT to https://www.phantomhelp.com/LogViewer/Upload/ and post a link back here.

Kick me when I'm down, eh...

He flew a round trip of 2 km - could he have flown 4x that for a 20% reserve? Sure.

He flew 10 minutes - could he have flow 4x that with a 20% reserve? Not sure at all.

Here is his voltage over time (and speed so you know something is happening).

The voltage is the orange line. It's "jammed" at 12.256V from time stamp 09:58.

The data is bogus. The data is from airdata (download the CSV and use good 'ole Excel).



(Edit - re-did graph with volts scale on right).

That's why I want the original TXT uploaded. That will tell us if this is modded, or he got a freakishly good battery.

You really think the voltage magically got stopped at 12.whatever? See the revised graph for his drone, above, to illustrate the volts behaving normalish and then freezing. Chain of custody: his TXT to AirData; AirData . CSV to my Mac.

Here is what the volts should look like over a flight, freaky battery or not.
Again with speed for a reference. Volts on right scale. Volts drop over time other than short term variance. (Just some random flight of my own - P4P) .

Hi Alan, sorry but what you mean by post that public ?

Hi Alan, sorry but what you mean by post that public ?

Disregard. I screwed up. Happens to me a lot. (Ask HP and Power). I've got the data.

If you had the original .DAT file from the drone itself, that would likely give you what you want to see.
