PWM - reduce PWM refresh rate

Hey All,

I was wondering how to change the PWM refresh rate of a quad (PX4 v1 - latest stable firmware)?
I cannot find a setting in QGroundControl to do this.

My escs cannot handle the 400Hz refresh rate.

My airframe is the generic 10inch ‘+’ quad.


You will not get a stable flight performance if they can’t handle it. I would recommend to switch your ESCs.
