Help

#

I built a drone a month ago and it flew fine and it had no problems. I built a new drone and finished it 2 days ago and when I armed the new drone, motor 3 was making a weird noise and I tried many things but nothing solved the noise problem, then I tried to put my old drones motor 3 onto my new drone to see if the problem was in the motor or in the flight controller, so I did and nothing changed, but I noticed that when I arm the drone and raise the throttle a bit then stop, the motors start to wind up like a jet engine and keep on winding up until they reach max throttle and the only way to stop them is to disarm the drone. So then I thought that maybe the problem is with the flight controller, so I took the bad motor and soldered it onto my good drone and then I armed it and the problem had happened again, so I thought that the problem was in the motor until I put back the original parts on to each drone then when I tried to fly my good drone the motors started to wind up like in the bad drone even though the original parts were in it.

So has my bad drone infected my good drone? pls help

The motors winding up is normal, if that is your question. Without the propellers on, it will wind up. With the propellers on, it will not wind up.

radiant ibex
#

really?

tall raptor
#

Look, I do a lot of trolling, but I do not lie to new people

#

If your props are set up correctly, this is simply the behavior of the I-term in your PID loop and will be fine

radiant ibex
#

how about the other noises in the video?

tall raptor
#

No idea. Seems like the old problem that we failed to resolve. I'll allow someone with new ideas to try.

radiant ibex
#

ok

worthy storm
#

👍

radiant ibex
#

I don’t think my drone is supposed to do that

#

Help

#

Guys what should I do?

#

@tall raptor do you see what I mean?

tall raptor
#

It actually sounds a lot better now

#

But I think the propellers are not on correctly

#

Can I get a top down picture of all 4 propellers?

radiant ibex
#

@tall raptor im positive that they are on correctly

tall raptor
#

They're on. Did you already check the motor direction, and that it matches the little diagram?

radiant ibex
#

yes

#

can I like restart the entire drone?

#

is there a way?

#

to like remove all the settings and firmware and try again

#

?

#

because I think this is not a physical issue

#

Im acually really upset because I was supposed to fly with my friends today

tall raptor
#

Nothing I can do about that but make sure everything works

radiant ibex
#

why are they doing that

#

😦

tall raptor
#

It's I-term windup. This is what happens when your props are not doing what the flight controller wants.

#

Happens on every drone if prop/motor direction is wrong.

radiant ibex
#

how can I fix it?

tall raptor
#

Tell you what. Put it outside in a safe, soft area like short grass and just blast the throttle. See what happens. Keep your finger on the disarm switch

radiant ibex
#

what will I prove with that?

#

I can do it but why? if you dont mind me asking?

tall raptor
#

Sure. I think something is set wrong. You think everything is set right. This way, we can identify the issue depending on how it goes wrong.

#

Can I take a peek at the motors tab in your BF page before that?

radiant ibex
#

ok

tall raptor
#

Looks about right.

radiant ibex
#

Like idk what went wrong, I did not change anything

#

I was flying fine 2 days ago but I changed one motor and brought it back and this happened

tall raptor
#

And is that motor spinning the right direction?

radiant ibex
#

yes

#

at least the last time I checked

tall raptor
#

Okay. So all four propellers are pushing air down and the drone won't lift off

#

?

radiant ibex
#

no

#

this is not the problem

radiant ibex
tall raptor
#

Uh huh.

#

You think it'll fly to the moon then

radiant ibex
#

listen to the audio

tall raptor
#

Either do that hover test or search "i term windup" in the server's search function, I don't wanna type this again

radiant ibex
#

This happens

#

Listen to the motors and watch the throttle

tall raptor
#

Are you reading what I'm typing?

#

This is normal.

radiant ibex
#

yes

tall raptor
#

Go outside without the goggles and hover it

radiant ibex
#

ok then?

tall raptor
#

It worked?

radiant ibex
#

no but I have to charge a battery first

tall raptor
#

Ok. I'll bet it won't hover.

radiant ibex
tall raptor
#

Probably right

#

When it goes wrong make sure to disarm

#

And take a video of it

radiant ibex
#

Ill do it real quick

tall raptor
#

Perfect

radiant ibex
#

@tall raptor

tall raptor
#

No liftoff whatsoever?

radiant ibex
#

there was a tiny bit of liftoff

tall raptor
#

And you gave it enough power?

radiant ibex
#

the problem is not that the motors are in the wrong direction or that the props are in the wrong direction

#

its this

tall raptor
#

If you show me the video where it spins up again...

radiant ibex
radiant ibex
#

sorry

tall raptor
#

BROTHER I KNOW.

radiant ibex
tall raptor
#

How about you just check the spin direction of that back right motor for me? And if you don't want to, take a top-down video of the drone just arming and disarming

#

Preferably with high frame rate or a slow motion mode

radiant ibex
#

no I can check for you

tall raptor
#

Do both if you can

#

I want to see

radiant ibex
#

do you want me to check all the motors?

tall raptor
#

Yes

radiant ibex
#

ok

tall raptor
#

Looks right to me

#

Yup, the only idea I have left is that you should try hovering it

#

Just went outside to see if my drone did this and it does not

radiant ibex
#

ofc it dosent XD

tall raptor
#

You could also pull a blackbox recording

#

To do this, erase the blackbox in Betaflight, then do the thing where it spins up again, then get the file out via Betaflight and send it to me

radiant ibex
tall raptor
#

On the left, there should be a tab called blackbox

radiant ibex
#

ok

#

how do I delete the black box?

tall raptor
#

Is it not on the blackbox page?

radiant ibex
#

erase?

tall raptor
#

yeah

radiant ibex
#

then

#

?

tall raptor
#

So do that, then do the thing where it spins up on the ground, then come back and hit activate mass, then you'll get something in your file explorer that you can pull a bbl or bfl file out of, then give me any one of them

radiant ibex
#

ok

#

theres a problem

#

I cant arm while its connected to beta flight

tall raptor
#

no no don't arm while its connected

#

disconnect the drone entirely, use your transmitter and do the same thing you did in that video you keep sending me

radiant ibex
#

wait like disconnect it from betaflight?

#

and plug in the battery?

tall raptor
#

ytea

radiant ibex
#

ok

#

which one?

tall raptor
#

those two that have btfl, one of them will do they are the same

radiant ibex
tall raptor
#

hmm

#

Motors 2 and 3 are spooling up

radiant ibex
#

really?

tall raptor
#

so this is the diagram

#

and its these two motors

#

which means the issue lies in yaw

radiant ibex
#

lies in yaw?

#

how about motor 4?

tall raptor
#

so, if you go into your setup page, where you see the moving little diagram, and you wiggle your drone left and right, does it copy?

#

Or does it do it in the opposite direction?

radiant ibex
#

nope

#

responds just fine

tall raptor
#

believe me when I say I am very confused

radiant ibex
#

im even more confused

#

ask me more questions that might help you find an answer

tall raptor
#

It's trying to turn left

radiant ibex
#

XD

tall raptor
radiant ibex
tall raptor
#

Wait

#

Motor order

#

If you spin up motor 1 on betaflight, does the same motor in the diagram spin up?

radiant ibex
#

yes

tall raptor
#

for all motors

#

?

radiant ibex
#

lets see

#

yes

#

they all do

#

idk what to do'

#

have you ever seen this happen to someone before?

tall raptor
#

No

#

I'm going to propose something weird

radiant ibex
#

do whatever you want

tall raptor
#

Flip it

#

And if it doesn't fly, send me blackbox again

radiant ibex
#

what switch

tall raptor
#

In the image I replied to

#

Also, one thing of note, the back right motor is the one you replaced, right?

radiant ibex
#

I did not replace it

tall raptor
#

Every time it starts winding up, the flight controller refuses to send power to that motor

tall raptor
#

Down until it drops, that motor doesn't get any power

#

Interesting

radiant ibex
#

I did not replace it btw

tall raptor
#

I got it

radiant ibex
#

I switched it up with my friends motor then switched back to mine

#

just to see if his motor is broken

#

where is the switch for reversed motor directions?

tall raptor
#

Above the little diagram?

radiant ibex
#

ok

#

I just switched them

tall raptor
#

So now the diagram is technically wrong, but I want you to try without changing anything else

radiant ibex
#

should I save the settings?

tall raptor
#

yeah?

radiant ibex
tall raptor
#

yeah]

radiant ibex
#

ok

radiant ibex
#

reversed blackbox

#

@tall raptor

#

if this dosent work ask me general things because I feel like the problem is going to have such an easy and dumb solution in the end XD

tall raptor
#

it didnt work did it

radiant ibex
tall raptor
#

how is it getting the SAME ISSUE WITH DIFFERENT MOTOR DIRECTIONS?

radiant ibex
#

I actually have no clue

tall raptor
#

ok fuck it

#

change it back

#

to the old settings

radiant ibex
#

ok

tall raptor
#

after that, give it enough power to get at least a foot off the ground. If it freaks out don't worry, disarm, then send the blackbox to me

#

By the way you don't need to erase the blackbox every time, only when its full

radiant ibex
#

oh sorry

radiant ibex
tall raptor
#

take your time

radiant ibex
#

ok thank you

radiant ibex
#

Wtf?

#

It came back to being normal again

tall raptor
#

i aint looking if its working

radiant ibex
#

No I just sent it in case

#

But How????

#

Like spending 6+ hours trying to fix this issue

#

And now it fixes itself lol
