Hey folks

I need clarification:
In the last youtube for Brain:

when using CrossFire 50 Hz, if you increase the FF above 1.0, P and D will be disrupt.!
Is there an explanation for this?

thank you

I'd ask on Betaflight's Discord, you have a higher chance of getting an answer from the experts on highly technical questions.

Ff is sensitive for signal jittering, high feedforward can cause issues.
As it is a boost feature, it does increase any unwanted signal either.

50hz doesnt match the signal quality for best controll, its benefical to gain rangeas example.

Link preset is gains high importance and does increase data quality.

Does preset 50hz crf the same issue ?

Slow link doesnt work for fast processing, fast boost features like ff dows make it even worse.

A link preset can improve, but the general issue named above stays.

Is there a need for 50hz? Why not 150hz?
All reasons speak for 50hz might also make ff less important.
