Hey guys, 
I recently bought a my first ever FPV drone and already received some tips and trick setting it up
(It´s the iFlight Nazgul5 V2 by the way).
We had some terrible weather over here and today was the first day that I felt like taking it outside for a maiden flight.

But then I ran into an issue, after having everything setup I wanted to try the maiden flight, just like Joshua Bardwell explains it in his videos (slow roll, pitch & yaw and then trying to throttle up). But everytime I applied anything more than the slightest bit of throttle the drone would literally flip out.

So I googled what the issue might be and quickly ran into JB´s video about this topic:


I opened up betaflight and concluded the following things:
1. The motors are in the CORRECT order within betaflight
2. The motors spin the wrong direction
3. The FC board was not facing forward (that should be fixed)
4. Custom motor mix is obviously not possible since it´s a bind an flight.

So I quickly changed the orientation of the FC board and now the 3D-grafic shows everything correctly. (I added 90 degrees to the yaw axis within the "board and sensor allignment" section on the configuration page:
   

Altough I am wondering if the "reset Z axis, offset: -230 degrees" on the setup page is important (because I could easily put that to 0 if nessecary):
   

Now I am wondering on how to change the motor´s spinning direction, since it is the opposite of the configuration tab within betaflight.
I saw a video about how to do it within BL Heli and even installed it. But I haven´t had succes connecting my drone to it and am wondering if it is ever the correct software or way to go.
So basically what I want to know is how to reverse the motor spinning direction?

Thanks guys for helping me out once again.

Do not worry about the 230 degree.

To change direction, you have to use Blheli suite if you want to do it through software. Depending on your esc, you will need either the blhelisuite or blheli32suite. Likely the latter.

If all your motors are spinning the wrong direction, it is likely the quad was configured for prop out spin. If that is the case, you can toggle "motor direction is reversed" in the configuration tab under the diagram of the quad. You will see the motor direction changes on the diagram. Make sure that the motors are spinning the same direction as the diagram. Also make sure you mount your props accordingly.

If you want to fly the default with props in, but can't use BLHeliSuite, then you swap two of the three motor wire with each other to reverse spin direction. You will need to do it for all four motors. This is a hassle to desolder and resolder.

If it's this configuration: https://www.getfpv.com/iflight-nazgul5-v...f-bnf.html then it's BLHeli_S. Once you get things running, I'd consider upgrading to BLHeli_M or BlueJay ESC firmware to take advantage of some advanced features (bidirectional DSHOT for RPM filtering, higher PWM frequency). I see you have BiDirectional DSHOT enabled. Is it working? Do you see RPM values on the motors tab with a 0% error rate?

Also, the above setup shows a props out configuration, so check that box that says "motor direction is reversed" like voodoo said.

Oh, thats super interesting. I'll try out the "motor direction is reversed" toggle first.
Didn't even know Betaflight had that option.
Thanks!

Great to know, because the BLHeli version I have right now doesn't seem to work.
I'll have to look into those advanced features. RPM Values are with 0% errors. So it works fine for as far as I can judge.
I followed the whole betaflight tutorial by JB am working on understanding what exactly some of the things I change actually mean. ?
But that's gonna be a fun process! Can't wait to get into the air and crash my drone a few times, haha.

Oh, didn't even notice the prop configuration on the pictures. Thanks for the heads up!

Just remember that the option in Betaflight does not change the motor direction. It just tells the Betaflight what direction you intend to configure.
