Hi,
apex 7" , 4.5.7, am32
When the throttle is sharply increased, the nose rises, when the throttle is released, it drops in the stab and acro modes. Which way should I look? If I raise pitch PID, the effect decreases, also raising ATC_THR_MIX_MAN parameter reduces the effect, but in my opinion this is a fight against the consequences. Betaflight flies cleanly on this drone, so I don’t touch the ESC. What other parameter can affect such behavior?

You have “The nod”. ATC_THR_G_BOOST was introduced to try and fix this and can have some beneficial effects. Try a value of 0.1 or maybe 0.2. A better solution is fast rate attitude but it won’t be available until 4.7
Thanks, I’m just reading about g-boost, I’ll try it tomorrow.
I’m not afraid of versions in development) in 4.7.0 they added a separate parameter for this?
No, but the basic problem is reacting too slowly to error - running the attitude control loop much faster mostly fixes this
ATC_THR_G_BOOST=0.3 (0.5 oscilations)
ATC_THR_MIX_MAN=3
Not ideal, but it’s not bad enough. Small accelerations with the throttle are not noticeable anymore, full throttle reset is a bit of a movement, but not critical.
