Air 3S drifting from take-off

[Meta4]

there is a possibility it could be your batteries if you're having a cell deviation the flight controller will prioritize stability over control this is the drones attempt to stop it dropping out of the sky on you

There are several very unlikely explanations (guesses) put forward in this thread, but this is the most unlikely.
There is no way that cell deviations would cause what the OP described.

Actually it happened to me and this was what it turned out to be two out of the three batteries I had had deviations it caused the drone to prioritize stability over control and it damaged the power management on the drone dJI is currently in the process of replacing the whole thing because they're acknowledged it was their fault I'm just saying it's possible and considering it took me pointing out the exact problem for them to look at it and go yep you're right and then decide to replace the thing I don't actually care it's not a thing I want to argue about you can believe me or not it's also very easy to prove or disproof you just open up the log go to the time where the incident happened and look for a deviation if it's there that's the problem it would be too much of a coincidence for them to both happen at once

you can believe me or not

I choose not to.

On the contrary.
Just because there are cell deviations, and some other issue does not mean the cell deviations caused the other issue.
I've inspected the flight data from hundreds of flights and incidents and having deviations in cell voltages is not uncommon, but there are always other real causes of the issues that are the problem.

If the cell voltage differences were big enough to cause a problem, the drone would be descending, not drifting.

No it wouldn't descend for safety reasons it's designed that way there are plenty of reasons why it wouldn't be a good idea for the drone to just descend when voltage dips on one of the cells. It tries to maintain its position it can drift it waits for you to give it to return to Home signal and then it will slowly climb to a height where it can safely return to home. just because you've never encountered something it doesn't mean it doesn't exist that's a completely arrogant way of looking at things. anyway have fun with that I really don't care what you think. I could give you the evidence, I could give you the communications with djis technicians confirmed this exact issue, and I could show you the logs where it happened. but I don't care enough I don't know why you're trying to turn this thread into a pissing contest what are you like 12. It's very weird that you're trying to use something like this to make yourself feel important, please don't waste my time I'm not interested.

Your logic is ridiculous it's like you're struggling to somehow reason yourself into being right in the face of evidence. that's hilarious can you bother somebody else with this I'm not interested.

 

[Meta4]

I could show you the logs where it happened. but I don't care enough

What a surprise !!

 

[Nexus Dragoon]

What a surprise !!

So you're saying if i asked you to prove that a cell deviation could not cause this you would care enough to prove it lol.
Ok then do it.
This is going to be hilarious.
Disprove thing that even the technicians at dji admitted was actual a safety function of the drone.
I am waiting show everyone how smart you are or are you all talk.
For me its far more interesting to watch you crash out about something that has nothing to do with you.
I am guessing you're not going to do anything.

Dream on.
It's clear that you're an uninformed blowhard and not worth engaging with.

you mean you have nothing, classic.
just as i predicted you had your chance to prove me wrong, and you couldn't do it.
you just proved you are full of it.
its probably time for you to stop, i have no desire to turn someone else's thread in to some school yard fight.

@Nexus Dragoon if you could share that flight log, I'd be interested in taking a look at that data.

Looks like you ran out of these these.

Lol my voice type wasn't punctuating and I honestly wasn't giving that much more effort than it needed

It's already sorted DJI is replacing it because of the issue. I can dig them up and share after work them if interests you. but they have already confirmed the conclusion I made. whether it was actually the cells damaging the drone or damage on the drone damaging the cells who knows either could be possible. but the end result was loss of control. I ended up with very limited control, it happened four times across two batteries mostly on one of them within a two-week period of receiving it. I just replaced it as DOA I can't take the risk as I don't have public liability insurance and I live in a population dense area. And rules where I live are enough of a pain as to that to be an issue.

Yeah, I’m following along and I completely understand. I was mostly just interested in taking a look at the data, not trying to prove what happened. I spend a lot of time reviewing flight logs, and I haven’t seen something like this before.

@Nexus Dragoon if you could share that flight log, I'd be interested in taking a look at that data.

And funny enough I actually used flight reader, I actually hit the 100 log limit looking for the problem, so there might have been more than four instances but I'm pretty sure that was all of them.

All good I just don't have access to them at the moment I will have later tonight when I get home. The only reason I suggested it could be the problem the problem is because it's not a common occurrence and the technicians are DJI did not pick up on it until I suggested it, and this guy said they couldn't find any problem so I thought in the absence of any other explanation it wouldn't hurt to check for that.

 

[msinger]

@Nexus Dragoon at this point, it’s hard to rule anything out until the OP shares the flight log data.

 

[Nexus Dragoon]

Yeah if you can't find any issue when you get the data it wouldn't hurt to see if there was a deviation that happened at the same time, not saying it's definitely the problem it's just something that they may not have checked for, but when I remember to send my data after work I'll just pm it to you, those logs have some info that I'm not 100% comfortable making public.
