Betaflight question

[Arne-W]

Hi @MoppelMat, I didn't find an other way to contact you than creation this issue 😄
You are the only one I know who uses a Diatone Mamba MK4 with BMI270 gyro stack on a 5 inch quad with betaflight. Could you please send me a diff of your settings or some screenshots of your PIDs and filter settings??
I have a lot of problems with my mk4 stack on my quad. I am using BF4.3 RC6 and it won't fly. I have massive noise problems on every small throttle punch the system freaks out and crashes with the default filter and PID settings. This is my 4th build and I never had such problems and therefore I though I should ask someone who has a flying mk4 stack.
It would be very cool if you could help a me little bit.

Hi Arne,

soweit ich weiß, bist du doch such von he?
Falls nicht, schreib ich dir später einfach nochmal neu :-).

ja ich hab den stack, aber auf nem 7“ ind nicht 5”…
Das macht das tuning aber schwerer und nicht leichter…
Du musst bei den filtern für diesen gyro ein paar sachen anders machen. Selbst diatone schreibt dazu auf deren page etwas.
Ich schicke dir gern nen diff. Es sollte sogar bereits einer im thread sein von mir…

Schsu mal ob du den findest, sonst schreib ich dir sobald ich aus dem bett bin. :-)

ich hätte sonst Threema als Messenger abseits von hier…

this is my current diff (50Hz Crossfire), GPS with MAG disabled (hopefully be fixed soon by a fellow coder), and some tweaks for the 7", should also "work" on a 5"

Moin, jo auf Deutsch ist ja doch immer ein wenig einfacher.
Erstmal vielen Dank für die schnelle Antwort und den Diff. Das mit den filtern hab ich auch schon gemacht - also Gyro lpf auf 250hz biquad aber den D lpf hab ich noch auf default (150hz).
Ich werde Deine Filtersettings mal testen - mal schauen was dann so passiert.
Ich nutze übrigens auch Threema: Meine Threema-ID: https://threema.id/232F6TXB
