RC_CHANNEL_OVERRIDE update rate

Hi everyone,

I’m new to the community but i’ve been playing with PX4 for some time now.
I’m playing with RC_CHANNEL_OVERRIDE but i’m concerned about the update rate.
My Raspberry Pi is connected by serial to the Pixhawk and send the override msg.

I’m not able to find at which frequency the Pixhawk reads those override msg ?
Is it fast enough to control a drone in ACRO mode ?

Thanks for your help
