0 Hi guys, I am using the Matek F4 AIO FC, but I got some yaw twitch problem.
I heard from some of you solved it simply by dropping pid loop frequency?
Or is there another solution?

1 Make sure you use low ESR capacitor on either your ESC's, or XT60 power (required on AIO boards)
Soft Mount your FC
Use lower looptime, such as 8K/8K or even lower, I've found people are mostly having problems on 16K/16K
If you are still having issues, drop your Yaw P gain, and increase your TPU to like 0.4

2 Which FC? The early 405 and 405 AIO had a twitch issue due to using a sensitive gyro. As JP said turning the gyro loop down to 8/8 fixes it.

139 I think they are talking about the early version. The later version is renamed to CTR.

2 you could try turning down p on your yaw. I'm not sure if you can turn up d on yaw, but if you can turn that up a bit and leave p alown. unless d is causing your motors to get hot, then turn down p .
f.k.
