Quad goes crazy on lift off
#1
Hi all,

I have a new build that when I arm and touch on the throttle, the drone just goes crazy and crashes (tumbles flips etc) 

It is an Omnibus F4 Pro using a 30A ESC's (called Quadracer), EMAX 22005S and FrSky XM+

I have the latest firmware on the FC and ESC and running DSHOT 600, checked motor and prop direction, reset and centred the top and bottom end throttle, have even dropped on BLHELI 

Ok so now I am lost and have been googling and fiddling for days :-)

I could not upload the BlackBox or TXT cli dump.


Cheers all and thanks in advance !
Steve

Sounds like your flight controller may be mounted incorrectly' Is the arrow facing forward?

Have you tried to re-calibrate the ESC's? Possibly check channel and/or motor order, FC orientation as well. To be honest I don't really know Wink just some quick brainstorming.
One of our pros will be along shortly I'm sure.
Good luck man, hang in there Wink Thumbs Up

Speaking of "props", you know about our rating system?  You can use the little thumbs-up "Rate" icon on the lower left of a post to give a member some well deserved "props". Big Grin

That was an easy one for me, as I've done it a few times. I know if a quad goes into instant "Tazmanian Devil" mode, it's usually board orientation. Glad you got it works out. Now if only all fixes were that easy....................

Of course, you can always save some propellers by using the 3D model in the configurator to check that the model moves the same way as the quad if you tilt it forwards, backwards, left and right.

That's what it's there for!

Yes it is and allowed me to quickly check once it was suggested rather than pulling the top plate off.

Mine went crazy too. I didn't think it would be possible. What does orientation fuck things up when the quad isn't supposed to keep itself lvl. It should only go sideways when I want to make it go forward. At least, that's what I thought. I hope this is my problem too.
Basically forward is sideways. How and what do I adjust to fix this, I tried some different things but it didn't work.

You have to change Board Orientation in your configuration. We can be more specific if you tell us what firmware you are using and what exactly you've tried. The more info, the better.

Thanks for the fast reply. So, I'm using Betaflight. I've managed to fix the orientation. (right was up, left was down, front was left and back was right.) I fixed it by changing Roll degrees and yaw degrees

But, when I do this moving the throttle on my transmitter up makes it roll. ( Example <-- Here I'm moving the throttle.)

All of this is my first time so apologies if I don't include enough info. Transmitter is Taranis QX7 Only basic stuff set up. 2 switches and the joysticks.

Edit: I smelled something burning when it was freaking out, but after taking the props off and plugging it into the pc everything seemed to work. (including motors) I hope I didn't already kill it.

You should only change yaw unless you have also mounted the flight controller upside down.

If your channels don't behave as they should, change the channel ordering. You have it set to "AETR1234" but it should be "TAER1234".

Some more reading and watching some basic introductions to Betaflight/Cleanflight on YouTube would really help you understand things. As your craft isn't set up properly yet, you should not put propellers on it until you have checked that everything is working as it should and is configured properly. Then you can put props on, go outside and try flying.

Oh, and knock it off with the gratuitous four letter words please, this isn't an adults only site.

First off. I expect a filter if using such words is a problem. That being said, I'll try to remember.

Secondly, do you have a suggestion to fix it? Top is right, right is bottom, bottom is left and left is top. I don't really know how else to change the orientation. I've been scouring the internet to piece things together since all of the parts are new to me and I'm never sure where the problem could be. (Transmitter, quad, settings)
Thirdly, does AETR1234 mean Mode 1 and TAER1234, Mode 2?
